Wi-Fi in a Nutshell

Wi-Fi was originally designed for Wireless connectivity between a single

Access Point (AP) and multiple clients

Wi-Fi is a mass market solution, delivering best effort service using unlicensed

frequency bands

Originally, Wi-Fi was intended to support LAN connectivity over a short range in an

indoor environment for private use

It was intended to deliver traffic on a best effort basis without QoS (Quality of Service)

or SLA (Service level Agreement) between an Access Point and the clients

Wi-Fi is by its nature a point-to-multipoint (PtMP) technology

Wi-Fi in a Nutshell

The huge indoor Wi-Fi market that has emerged over the last few years has made the

technology attractive for outdoor applications due to its apparent economy of scale

An examination of the Wi-Fi outdoor user base, indicates that it is commonly

deployed by small limited budget ISPs:» Serving residential users without QOS or SLA

» Over short ranges of several kilometers

» Offering Internet access with low capacity under 1Mbps

The ready availability of chips and reference design in the industry, has reduced the

entry barrier for potential manufactures tempting many vendors worldwide to offer

this technology as a low-end broadband access solution


Wi-Fi Performance Overview

Interference in the unlicensed band used by the Wi-Fi (2.4GHz) is increasing steadily

with the proliferation of Wi-Fi devices

In addition, its incidence is quite random. Part of this interference is due to the

concentration of many Wi-Fi transceivers in a given area and part of it is due to other

systems using the same bands



It dramatically affects both the Wi-Fi service availability and capacity:

1. Wi-Fi link operation is not guaranteed due to interference

» The operating frequency channel (20MHz) in many of the Wi-Fi transceivers is manually selected during

network configuration

» Intensified interference while operating the equipment may intermittently drop the Wi-Fi link until the

interference drops to an acceptable level or until channel reselection takes place which may require

manual intervention

» Those Wi-Fi transceivers that dynamically select the frequency channel search for signals with a Wi-Fi

pattern only: During channel selection, they check for the presence of a WiFi signal rather than measure

the spectral energy in the channel

» That means that they are blind to any type of interference not due to Wi-Fi. Thus, these transceivers may

select a channel that is not subject to Wi-Fi interference, but does suffer from interference due to other

radio systems with a spectrum pattern different from Wi-Fi



It dramatically affects both the Wi-Fi service availability and capacity:

2. Wi-Fi link capacity is highly vulnerable to Interference

» Wi-Fi clients and AP sense the air-interface before sending data

» Having certain level of interference in the channel might delay the transmission for short or long periods,

» hence, reducing the effective capacity with no way to avoid it

» In addition, when error data is received, the Wi-Fi sender resends the whole packet from the beginning

» In harsh environment this approach not just reduces the capacity but also increase the latency and makes

it erratic, therefore damage the QoS of time constrain traffic as VoIP and video


Long term experience shows that on average, the Wi-Fi network capacity for TCP trafficis less than 30% of the maximum modem rate

Wi-Fi Deployment Limitations

Wi-Fi capacity performance can easily be degraded in certain deployment or service

scenarios, unless special care is taken – and even that may not help

Such degradation increases the TCO (Total cost of ownership)

Typically, the initial equipment cost is a small part of the TCO

But - note that compromising on transceiver equipment quality will also lower the

Link capacity



Capacity degradation due to a concentration of APs (Access Points)

» The Wi-Fi transmission and reception periods are not constant and subject to the size of the transmitted

packets

» Hence, when several APs are collocated on a site their transmission and reception are not synchronized

» Consequently, they interfere with each other even though they may transmit on different frequency

channels

» The end result is significant reduction of link capacity over a given distance or alternatively, reduction of

link distance for a given capacity

» Spatial separation of the APs improves the performance but requires additional costly space



Wi-Fi cannot support delay sensitive services

» Being designed for best effort data transmission, Wi-Fi is not “aware” of delay sensitive applications such

as video and voice

» It therefore treats them as regular over-the-air data traffic increasing the end to end delay

» To make matters even worse, this increases the delay variation of delay sensitive traffic

» There are some Wi-Fi clients that support the WMM (Wi-Fi priority policy for Multi Media), being able to

prioritize multimedia packets over other packets during transmission

» Such prioritization is essential but not enough: The Wi-Fi air interface (meaning the algorithm for

modulation selection) is intentionally tuned to deliver packets with PER (Packet Error Ratio) up to 10%,

relaying on higher layers such as TCP to re-transmit the packets with errors. Consequently, the

multimedia packets, carried over UDP are not retransmitted upon error, degrading the end to end

performance of voice and video services



VoIP traffic dramatically reduce Wi-Fi capacity

» Due to the Wi-Fi air protocol (Air link sensing before transmission and acknowledgment mechanism), a

short packet of 64- 128 bytes as used by VoIP, reduce the Wi-Fi capacity by tens of percent

» Typically, one AP can handle only 7-10 VoIP channels! Obviously, this capacity shortage can be

compensated for by adding more APs, leading in turn to capacity degradation due to concentration as

described in the first bullet above




To Summarize:

1.Wi-Fi is aimed at indoor LAN connectivity for best-effort data applications2.Wi-Fi technology suffers from inherent drawbacks that prevent it from being appropriate to high-end broadband applications like long range backhaul, mission-critical or business applications3.The vulnerability of Wi-Fi links to interference results in erratic capacity in an outdoor scenario

All of these weaknesses limit the Wi-Fi solution investment protection, adding up to a relativelyhigh Total Cost of Ownership along with degraded price/performance at the high end

Performance Overview


Automatic Channel Selection (ACS)

» Both during configuration and as a result of the link dropping, RADWIN radios automatically chooses the

clearest operating channel. In the event of a link drop it re-synchs itself within few seconds. This

minimizes service interruption due to interference and ensures high link availability

Synchronous TDD

» The WinLink 1000 transmits and receives on fixed timing basis, regardless the level of interference.

Therefore, unlike Wi-Fi, its transmission cannot be blocked by high level of external interference

Automatic Repeat reQuest (ARQ)

» The WinLink 1000 transceiver checks every portion of the packet immediately when it received and upon

error it requests re-sending again and again it until it correctly received. This process avoids loss of

capacity due to retransmission of the whole packet. It also improves the link error performance to PER

better than 0.1% for time sensitive UDP traffic as TDM, VoIP and video while keeping the latency to the

minimum necessary


Support of Data and TDM

» WinLink 1000 is built to support both data over Ethernet and native TDM. As mentioned above, special

care of TDM traffic enables low error rate with low end to end delay. · Stable and fixed capacity for

variety of services The WinLink 1000’s air interface ensures that the net capacity is indifferent to packet

size. It is therefore highly efficient even for services with short packets as VoIP

Support of collocated PtP links

» The WinLink 1000 supports Hub Site Synchronization (HSS). HSS is a unique Radwin collocation

technology designed to support Multiple Point-to-Point architecture from one hub site to many remote

sites. It avoids mutual interference between the collocated PtP transceivers, therefore maximizing the

dedicated capacity per site

Performance Overview

Conclusions


1. Wi-Fi offers low cost outdoor wireless solution to the low-end market with best-

effort SLA

2. As shown, Wi-Fi link’s availability and capacity are highly vulnerable to outdoor

interference

3. Further, its capacity is subject to the type of traffic and to the network topology,

therefore it does not fit broadband mission critical applications as backhaul or

business environment

4. This raises serious questions about the true economics of Wi-Fi: Low initial costs,

heavy operational costs due to “patching” an inferior solution along with a loss of

customer confidence – and the customers, themselves!

Conclusions


5. RADWIN radios are designed to ensure high availability of its broadband link under

harsh and noisy conditions – they maintain stable and predictable capacity with short

latency, regardless the traffic characteristics or the network topology

Air Protocol Highlights

HBS Activation

The HBS will not transmit unless it has been activated (Inactive State)

Upon reset or activation, the HBS scans all channels (selected in ACS) for the less

interfered channel (lowest noise)

The less interfered channel is assigned for the entire sector

When activated, the HBS will commence transmitting and receiving packets related to

sector management only


a) HBS IP address

b) HBS Sector name

c) HBS Frequency (or ACS)

d) Sector ID

HBS Activation requires:

HSU Registration

Assuming that the Sector HSUs are mounted aligned and powered up, the HSUs

will discover the HBS establishing links for management only.

At this point the HSUs may be managed over the air.

As soon as the HSUs are configured to your satisfaction, you must register them

on the HBS.


HSU Registration

Registration of an HSU enables service traffic between the HSU and the HBS.

During the registration process, you assign time slots to each HSU.

A total of 16 time slots are available to each HBS to be distributed among the HSUs in

the sector.

The relative number of time slots determines the relative amount of service each HSU

will receive.


HSU Registration

Each HSU receives at least one time slot.

To disable an HSU you must deregister it.

A suspend mechanism is also available, to suspend service on an HSU for a limited

period.

For each registered HSU, you can set separately, the uplink and downlink Maximum

Information Rate (MIR) in Mbps or leave it at Best Effort.

You may also manage an HSU Connection table to enable and disable connectivity

between HSUs in a sector.


“Synchronize HSU” – HSU is synchronized to HBS. HSU might have default Sector ID or the same Sector ID like the HBS No service to HSU yet

“Register HSU” – HBS commands to the synchronized HSU the required Sector ID and services HSU is associated and registered to the HBS HSU receives the same Sector ID HSU is assigned with a service (Time Slots)

“De-Register HSU” – HBS commands to release the HSU from the HBS The HSU deletes its Sector ID The HSU starts re-scanning of HBS

“Suspend HSU” – The HSU will not communicate the original HBS for a duration of configurable X seconds The HSU is re-scanning for other HBS with the same Sector ID

Terminology


Secure Registration

To complete a HSU installation, users are required to register the HSU on the HBS

To register the HSU on the HBS, the HSU needs to be discovered first by the HBS

Only the HBS can register the HSU(s)

Sector site planning consists of a set of surveys, which must be carried out before any equipment is deployed.

If for some reason, the outcome of any of these surveys is negative, HBS or HSU re-location will need to be considered

Recommended Equipment

For Preliminary Survey:

• Topological map of the area• Urban map of the area• Compass • Link Budget Calculator and/or Radio Planner

For Physical Survey:

• 100 meter tape measure• Ohmmeter, to check ground connection• Binoculars• Map• Digital camera• Paper, pencil, and a clipboard• GPS device (optional)• Compass (optional)


Recommended Equipment

For RF Survey:

• Spectrum Analyzer with Max Hold function capable of capturing screens and data • RF accessories (connectors and cables)• Communication devices (for example, cellular phones, or a set of walkie-talkies)

For physical installation:

• Crimping tool for RJ-45 (if the ODU-PoE cable is without connectors)• Spanner/wrench 13 mm (½”)• Drill (for wall mounting only)• Cable ties• Sealing material• ODU grounding cable 12AWG


Preliminary SurveyPerform before visiting potential installation sites:

1.Mark the designated installation sites on a topographic map of the area

2.Measure the distance between the sites; check that it is within the specified

range of the equipment

3.Check the area between the two sites for obstructions such as:

• High ground - hills or mountains

• Lakes or large bodies of water

• Construction cranes


Outdoor CAT-5e; Maximum cable length: •100m for 10/100BaseT•75m for 1000BaseT (GbE PoE)

Preliminary Survey (continued)

4. Determine and record the compass bearings between HBS and HSU ODUs,

relative to north.

5. If there are obstructions between the two sites, calculate the Fresnel Zone

6. If the sites chosen do not meet requirements, consider alternative sites.

7. Use the Link Budget Calculator (on the CD supplied with the equipment or using

the RADWIN Manager) to determine the expected performance.


Physical SurveyEnsure that the sector sites are suitable for the wireless network:

1.From the compass readings taken in the preliminary survey, find the azimuth (horizontal position) that each HSU ODU should face towards the HBS ODU.

2.Using binoculars, locate any obstructions such as tall trees, high buildings, hills or mountains. Look for other RF towers between the two sites. Mark the locations of the obstructions on the map.

3.Determine the location for the ODU (having regard for existing rooftop installations and tower space). It should be above any obstructions, considering the Fresnel zone.

4.When installing ODU on a tower, make sure that the tower is far enough from overhead electric power lines.

5.Determine a location for the indoor equipment; it should be as close as possible to the ODU. At an existing site, there is probably an equipment room with cable-routing channels.


Physical Survey (continued)

6. Measure and record the path length of the cable from each ODU position to the indoor equipment room.

7. Determine the ground and lightning connection points of the installation. The ODU and PoE must both be grounded.

8. Using the Ohmmeter, measure and record the resistance of the required installation to the grounding point. The resistance must be less than 1O ohm.

9. Review the results of the physical site survey. Decide if the site is suitable for the wireless network installation:

• If the site is suitable, you may proceed (RF Survey)• If the site is not suitable, survey another site


ODU operating temperatures: -35°C to 60°C (-31°F to 140°F)IDU operating temperatures: 0°C to 50°C (32°F to 122°F)

RF Survey

• The RF survey examines the wireless environment of the installation site, to

determine whether there are available channels within the radio operating

frequency band.

• An RF survey is performed using a spectrum analyzer.

• It is advisable to familiarize yourself with the spectrum analyzer before going out

on site, specifically the Max Hold and Marker functions.

• You should perform the RF survey at each of the proposed sector sites.

• The survey should be carried out during a busy time of day, to best judge the

worst-case radio interference. Allow 2-4 hours duration for a good RF survey.


RF Survey (continued)

Interference may arise from -

• Self-interference from collocated RADWIN radios

• Other collocated radio devices installed on the same site.


Use the Link Budget Calculator to Use the Link Budget Calculator to determine the minimum Tx Powerdetermine the minimum Tx Powerrequired to maintain sector stability.required to maintain sector stability.

RF Survey (continued)

To avoid or minimize interference, follow these recommendations:

• For collocated RADWIN units, use an HSS unit to synchronize between them.

• Select a different operating channels for each collocated RADWIN unit.

• If one or more collocated units are not RADWIN units, ensure that there is a physical

separation of at least three meters between a RADWIN unit and any other collocated

radio on the site.

• Use the largest possible frequency gap between these units

• Choose the best frequency channel (as clear as possible from interference). You may

be able to change the band used for the sector - depending on HBS model and

regulations.

• Decreasing the Tx Power of a sector will reduce collocation interference


Grounding


All RADWIN products should be grounded during operation:

1.The ODU should be earthed by a wire with diameter of at least 12AWG.

2.RADWIN 5000 HPMP ODUs must be properly grounded to protect against

lightning.

3.It is the user's responsibility to install the equipment in accordance with Section

810 of the National Electric Code, ANSI/NFPA No.70-1984 or Section 54 of the

Canadian Electrical Code. These codes describe correct installation procedures for

grounding outdoor units, masts, lead-in wiring and discharge units. It also lays down

the size of grounding conductors and connection requirements for grounding

electrodes.

Installing the Hub Synchronization Unit

103


• When several HBS sector radios/PtP radios are collocated at a common hub site, interference may occur from one unit to another.

• The RADWIN Hub Site Synchronization (HSS) method uses a cable connected from the master ODU to all collocated ODUs; this cable carries pulses sent to each ODU, which synchronize their transmission with each other.

• The pulse synchronization ensures that transmission occurs at the same time for all collocated units.

• This also results in all of the hub site units receiving data at the same time, eliminating the possibility of interference that could result if some units transmit while other units at the same location receive.

For a single HSS unit, ensure that the collocated units are connected in sequence from SYNC 1.

If an ODU is removed from the hub site, then all remaining ODUs must be reconnected to maintain the connectivity.

You may cascade (daisy-chain) two or more HSS Units with an HSS cable.

Installing the HSSU

104


• A single HSS unit supports up to ten collocated ODUs (PtMP and/or PtP, co-exist).

• In addition to each unit being connected to its PoE device, the collocated unit has an additional cable that is connected to the HSS Unit.

• The HSS Unit is a compact, weatherproof (IP67) connector box that is installed on the same mast as the ODUs.

• All collocated units connect to this box using CAT-5e cable.

• The HSS unit is supplied with ten protective covers; any port not in use must be closed with a protective cover.

Installing the HSSU

105


1. Unscrew the protective cover from the port marked SYNC 1.

2. Connect the RJ-45 connector from one end of the prepared CAT-5e cable to SYNC 1.

3. Connect the other end of the CAT-5e cable to the ODU connector labeled SYNC.

4. Tighten the protective seal that is on the prepared cable over the RJ-45 connector.

5. Repeat for all ODUs that are

to be collocated at the hub site.

6. The next ODU to be

connected is inserted in SYNC 1,

SYNC 2, followed by SYNC 3 and

so on.

Cascading HSSUs

106


1st HSSU 2nd HSSU

Cascading HSSUs (continued)

107


1. Up to nine ODUs may be connected to the first HSSU (left) using HSS ports SYNC 1, SYNC 2, SYNC 3,... up to SYNC 9 in consecutive order without leaving empty ports.

2. The next available SYNC port of the first HSSUN (left) should be connected to SYNC 10 of the second HSSU (right)

3. In the example below, the next available port on the first HSS unit is SYNC 6.

4. The 2nd HSSU may be filled out with up to nine more ODUs in reverse order.

Total HSS Cable Length

108


The total path of the HSS sync pulse must not exceed 300m. This applies no matter how many HSS units are used.

For example, for a HSSU with 5 ODUs, one should calculate the total length as the path the pulse signal travels till it reaches its final SYNC port (last ODU):

Total length = L1 + L2 + L3 + L4 + L5 + L6 + L7 + L8, where L2=L3, L4=L5 and L6=L7

In the event of an HSS installation fault, the HSU ODU will sound a beep patternaccording to the following chart:

Please note that only HSU ODUs are provided with the Buzzer sticker.

Installing the GSU

110


• The GPS-based synchronization unit (GSU) is designed to handle inter-site interferences under large-scale deployment scenarios.

• The GSU is an outdoor unit consisting of a standard Wireless Link enclosure, a GPS antenna and a PoE device.

• The GSU is connected to a HSS Unit using a standard HSS cable.

• It synchronizes the transmission timing of multiple Hub-Sites to the same clock source thus eliminating mutual interference.

• The GSU receives a synchronization signal from the GPS once per second.

• It distributes a RADWIN proprietary synchronization signal to all other ODU units using the RS422 protocol and the standard HSS mechanism, where the GSU acts as an HSM unit.

• If the GSU does not receive a synchronization signal from the GPS for 30 seconds, it moves automatically to Self-Generation mode and acts as a regular HSM unit, until GPS signal recovers.

Installing the GSU

111


GSU packing list:

• 1 x GSU• 1 x Mounting Kit• 1 x GPS Antenna• 1 x GPS Antenna Mounting Kit• 1 x RF Cable, 1.5m• CD

1. Mount the GSU and antenna.

2. Ensure that its ODU port connected to its PoE

3. device and the HSS cable is connected to the HSS

unit as shown.

4. The external LAN port of the PoE device is

connected to the managing computer.

5. The default IP address may be inaccessible and

you may not use the Local Connection method

over a network.

Mounting the ODU

112


• Each ODU should be pre-loaded with an IP address.

• This may be done prior to deployment in the field, or on-site using a Laptop

computer.

• The ODU can be mounted on a pole or a wall. In both installations, the supplied

mounting kit is used to secure the ODU.

1. Ensure that the ODU is properly grounded2. Mount the ODU onto the pole or wall. Ensure that the unit is oriented so that the

cable connectors are at the bottom3. Do not tighten the ODU to its mounting brackets until the alignment process of the

antenna is complete4. Ensure that there are no direct obstructions in front of the ODU or interference from

man-made obstacles

Aligning HSUs to HBS

114


HSU antenna alignment to an HBS can be performed using HSU ODU’s audible tone.

1. Ensure that the sector antenna of the HBS is aligned precisely to the sector it is

intended to cover. Use a compass and topographical maps to do this.

2. For both the HBS and HSUs: Using a coax cable with N-Type connectors, connect

the vertical polarization connector of the antenna to the ANT 1 connector of the

ODU.

3. Then, using a second coax cable with N-Type connectors, connect the horizontal

polarization connector of the antenna to the ANT 2 connector of the ODU.

4. Ensure that power is connected to the site PoEs across the sector.

Aligning HSUs to HBS (continued)


5. Provided that an HSU detects the signal from the HBS, the ODU starts beeping 20

seconds after power up, and continues beeping until the HSU is aligned to the HBS,

and the alignment is complete.

6. Make a horizontal sweep of 180 degrees with the HSU antenna so that the

strongest signal from the HBS can be detected.

7. Slowly turn the HSU antenna back towards the position of the HBS, listening to the

tone until the best signal is reached. See the following figure for audible signal

variations.

Aligning HSUs to HBS (continued)

• Three beeps and a pause is 'best signal so far'

• Two beeps and a pause is 'signal quality increased'

• One beep and pause is 'no change in signal'

• Long beep and short pause is 'signal quality decreased'

• One beep and a long pause is 'no air link'

• Any other signal does not relate to antenna alignment

If you require a band that is not listed, click on “Adding bands” and proceed to the next slide…

HBS Sector Settings: Adding Bands


Adding bands requires a license which can be generated using the URL listed below

Changing Bands


When changing bands is in process, the HBS will change the band to all the HSUs within the sector

Changing bands to a specific HSU is possible as well (right click the HSU)

HSU Connectivity Matrix


Click here to configure the connectivity matrix


Here we have only 2 HSUs in the sector

Each HSU has access the Network, HBS management and User data (other HSUs)

In this example HSU #1 has no access to ALL services

HSU #2 has full access to ALL services



In this example we have 16 HSUs registered to the HBS

All HSUs can access the HBS and Network

However, none can access the other HSUs in the sector (none-VPN)



Mark/tick the checkboxes that

supports the following scenario:

1.All HSUs can access the network

2.None can manage the HBS

3.Odd HSUs can talk to each other

4.Even HSUs can talk to each other

5.Odd & even HSUs cannot talk to each other


Reset & Deactivation


Two features remain uncovered:

1.HBS Reset 2.HBS Deactivation

You may practice now these 2 cases…

Bear in mind that Deactivation will result in a TX Mute where the HBS stops transmission and cannot detect the HSUs in the sector

Click here (Bell shaped icon) to

Active Alarms


The Active Alarms window show the current alarms that exist in the HBS topology (sector):

1. HBS alarms2. Alarms of all HSUs within the sector

Using the Spectrum Viewer


Two ways to run it:

From the HBS – •Users have a choice of analyzing all sites in the sector in one run, or making a selection.•Users may expect a “noise hump” around the channels used by the sector, due to the duty signals from the HBS.

From the HSU – •Spectrum View may also be run on a managing computer directly connected to an HSU.•Remember that in such a case the results will be quite different if the HSU is part of a sector (registered or not) or if it is completely stand-alone, for example using a different spectral range and operating Band from the HBS.

Using the Spectrum Viewer


Where is the Spectrum View Data stored

• Spectrum View data is always stored in the ODU originating the analysis.

• The HBS maintains the last Spectrum View analysis data for all members of the

sector.

• If you run Spectrum View from a directly connected HSU, it stores its own data,

which may be quite different from the analysis obtained for the same HSU from the

HBS.

Launching the Spectrum Viewer


Click on the SA button

in the Manager main

window

Scanning Options


• The analysis range is limited from 4900 to 6050 MHz with a maximum difference of 500MHz

• The timeout is the maximum analysis time per site

• Users may start and stop at any given time

• Highest Interference Scanning is also available

• Scanning will cause the whole sector to stop service for up to 120 seconds or until the Stop button is pressed.

• The scanning results of previous scan will be displayed until the Start button is pressed again.

• There is no difference in principle between running a Spectrum View analysis for an HSU and running it for the HBS.

• There is a major difference between running Spectrum View on an active HSU (registered or not) or in total isolation from the sector.

Here is what happens in total isolation:



In this is what happens when the HSU is within a sector:The hump reflects the duty cycle signal from the HBS centered on the currentchannel (barely seen but circled).

Configure here the HSU antenna parameters such as:

Type (Dual / Single) Max. allowed TX power Gain Cable Loss

Your configuration will determine the EIRP

Bear in mind – When registering a new HSU in a

sector, you will need to configure first the antenna type. Should you fail to remember this step, the Manager will display an alert during the registration process


HSU Configuration – Management – Trap Dest.

An effective managed network requires SNMP Traps to be sent from the agents (HSUs) towards the Manger (SNMP Manager)

To support sending the Traps from the HSUs towards the SNMP Manager(s), the user needs to configure at least one Manager (IP address and TCP Port)

Failing to configure Trap Destination(s) will result in failing to receive the HSU actual alarms. Next update will take place when the Manager will poll the HSU (according to Polling cycle user had configured).

Configure the IP address of Radwin Manager PC (use Port 162) as the first Trap Destination


To secure local management (PC to HSU), configure here the management VID and P-Bit

When not enabled, the local PC only requires to know the IP address of the HSU to gain access…

Please note – you will need to know the password as well when logging in to the HSU

Guide lines

Before we start reviewing the configuration steps and supported modes, we need to be familiar with the following guide lines:

1.All VLAN actions and manipulations that are related to DATA, are configured and performed by the HSU(s)

2.The HBS does not audit the ingress VLAN TAG coming from the HSUs within its sector

3.To control the traffic within the sector we can use the Connectivity Matrix (HBS Configuration)

HSU Configuration – Ethernet – VLAN Disabled When you wish the radio to transport all frames transparently regardless of L2 or L3 properties, set mode to Disabled.

The Ingress port and Egress port will ignore the L2 overhead

In this mode there is no L2 processing

HSU Replacement

Getting started


Let’s assume we have 2 HSUs in the sector

Both are registered and managed by the HBS as seen in this screen capture

Important Note –

To replace one HSU with another, you need at least one HSU available in the sector

When the sector is fully populated and all the HSUs are registered, users will not be able to initiate the “Replace” command

HSU Right-Click Menu

Right click the HSU to expose its menu of features and functions

When there are no free HSUs in the sector to take over, the “Replace” option is not feasible

As seen in this screen capture, the “Replace” command is disabled
