HauteSpot NetworksCustomer and Technology Overview


What Is Haute?Haute - adj. Pronounced "hÕt". From the French word meaning high or

elegant. The Haute Route is the classic ski touring route between the two most famous alpine centers in Europe - Chamonix in France and Zermatt in

Switzerland. A Haute Router from HauteSpot Networks is the leading broadband wireless access device available today

Any Camera, AnyWhere®

From 20 yards to 20 miles, from CCTV to HD Broadcastproduction, HauteSpot Networks’wireless technology allows anycamera, or weather station, to belocated virtually anywhere.

Core Message


Video surveillance is the “killer” app for wireless broadband

Video is constrained today by wires and slow wireless

High definition real time video has unique demands for wireless—Low Latency—Consistent Delay Variation

Bandwidth requirements grow in parallel with resolution and frame rate requirements. The problem is only growing bigger.

Camera density requirements are growing rapidly

Existing wireless topologies and protocols do not support video well

802.11—Carrier Sense Multiple Access Collision

Avoidance—Designed for heterogeneous data—Short range—Non-deterministic timing—Stop and Wait— Basis for mesh networks

Mesh—On top of 802.11 adds link quality based

routing—Designed for heterogeneous, non-time

dependent data—Adds routing delay variation on top of

802.11 collision delay


HauteSpot TDMA-like ProtocolTime Division Multiple Access

Master controls stations— Allows for interference avoidance

Uniform timing

No collisions

ARQ error correction

1/2, 2/3, 3/4 Forward error correction

Standardized frame sizing


What’s Wrong with 802.11?802.11 Protocol is Carrier Sense Multiple Access/Collision Avoidance

Listen to No Traffic

Send Data

Wait for ACK

If ACK received, send next

No ACK, Back off Random Period. Begin resend

Timing Variation = Jitter


802.11 CSMA/CA protocol802.11 Uses Carrier Sense Multiple Access/Collision Avoidance

Collision = Jitter

InterferenceAvoidance

Mesh—Every node is a peer—Must share common frequency—Interference on a channel from

a high gain radiator could bring entire network down

HauteSpot TDMA—Master monitors signal and noise—Stations follow the frequency of the

master—If interference rises on frequency,

master will select the best frequency in band and move

—Stations follow master frequency


How Far Can We Go? Physics Limits Range

High Definition Video needs Bandwidth—25 to 81Mbps of actual throughput is

required—20 to 40 MHz channel width is required to

achieve this performance, even with the best modulation schemes (16 or 64-QAM)

—To get 20 to 40 MHz of contiguous bandwidth you need to move to higher frequencies

—Higher frequencies are more directional—Higher frequencies have more path loss

—High data rate ~ 8 mi—Lower data rate ~ 20 mi—NLOS ~ 2 mi but can be further using

lower rate at 900MHz


Licensed vsUnlicensed

Licensed (765MHz, 1.7GHz, 2.1-2.3GHz, 2.5 -2.7GHz, 3.3-3.7GHz, 4.4GHz 4.9GHz, 5.9-6.1GHz)

—Limits Interference—Coordinated

Unlicensed (900MHz, 2.4GHz, 3.65GHz, 5GHz)—Free—Unreliable due to interference—No co-ordination (except for 3.65GHz)

How Can You Achieve Reliable Unlicensed Links?—Narrow beam antennas—Vary antenna polarity—Adaptive Noise Immunity—5 or 10 MHz channel widths—Dynamic Frequency Selection/scripting—TDMA – Like protocol (TLP)

Only HauteSpotSupports All


Competitive Technologies

802.11—Slow – less than 15Mbps—Short Range - mostly—Contention Based – Lots of jitter—Prone to interference—Insecure—Not frequency agileMesh—All issues of 802.11 plus delay

variation—Much more reliable and easier to

install than 802.11

COFDM Microwave—Very Expensive—One Way Only—Completely Proprietary—Not extensible

802.16—Base station silicon too expensive

and too big—Intended for carriers, doesn’t

economically scale down yet—Designed for Asymmetric

download (web surfing)—Not currently frequency agile—Time Slotted, but still prone to

delay variation

EvDO/GPRS—Slow (less than 300Kbps)—High Latency—Fair access policy limits bandwidth

TransportProtocols

HTTP. Easy to use, passes through firewalls, not very efficient (TCP), heavy load on server, few simultaneous usersMulticast. Uses broadcast domains to send out traffic. On single layer 2 networks it works well (UDP),but to route you need IGMP, PIM and tunnels across the public internet. Difficult to deployUnicast. Uses UDP streams which have to be set upin advanced between server and client. Low overhead, good for static links, but not so great for dynamic stream sharingRTSP/RTP. Real time streaming protocol is a control layer that allows clients to make requests of server. Real time transport protocol is the actual transport stream being controlled by RTSP. UDP, very efficient.—RTCP. Real time control protocol used to pass back feedback from clients to server on network conditions and video quality


How Big A Pipe is Needed ?Encoded Stream Sizes


BestPractices

USE UDP, not TCP

Use Multicast or RTP/RTSP

Limit back traffic like management

Use RF channel segregation to achieve bandwidth

Don’t use 802.11

Avoid mesh

Avoid repeating on single radio
