FEATURES OF LTEBY

CYBERSPACE DEPARTMENT OF TECHNICAL

OUTLINE

• Why LTE?

• LTE UE

• Cyberspace LTE

WHY LTE?

Higher spectrum efficiency drives cost-per-bit reduction.

LTE has higher spectrum efficiency than all the past data network, hence lower operation cost per bit. More bits are transmitted and received at a lower cost.

1. COST REDUCTION

WHY LTE?

Applications now have a very sky-high demand for high speed and low latency. Such as Mobile-TV, Online gaming, VoIP, Video-on-demand, See-you-see-me

2. NEXT GENERATION APPS

WHY LTE?

LTE has fewer network components and migration path is easier and cost effective.

3. SIMPLIFIED NETWORK ARCHITECTURE

WHY LTE?

LTE can run on wide range of bandwidth depending on the one that fits the operator technological and business model. The bandwidth; 1.25MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz.

4. SCALABLE BANDWIDTH

WHY LTE?

With LTE, you can have uninterrupted connection moving at high

speed of about 350Km/h, this is not possible with other

technology.

5. MOBILITY AT HIGH SPEED

LTE UE CLASSES

UE classes are as presented below;

• It should be noted that UE classes are constantly being developed and more

classes are now specified by 3GPP (up to class 10), but the five classes are

physically available in the market.

• Higher classes of LTE UE have improvement on the capability to do 64QAM

on the UL and higher order of MIMO transmission.

WHY LTE?

LTE supports roaming with the 3GGP mobile networks. However,

these services are not easy to achieve some other technology like

WiMAX.

5. ROAMING

WHY LTE?

LTE needs lower power consumption than other

telecommunication multiple access technology. One of the

reasons of this is the use of SC-FDMA modulation in uplink

channels.

6. ENERGY EFFICIENCY

CYBERSPACE LTE

• Cyberspace LTE network run on TDD Technology. TDD is Time

Division Domain. Which means that both downlink and uplink

use the same frequency.

• FDD is Frequency Division Domain which means the downlink

and uplink use different frequency

1. TDD OR FDD

CYBERSPACE LTE

• Cyberspace LTE network covers only Lagos (for now) with 100

eNodeB (eNodeB are base stations).

• The network has the potentials of growing in the nearest

future.

2. COVERAGE

CYBERSPACE LTE

• Cyberspace LTE network run on NCC Licensed band 42 and

frequency 3465 – 3485MHz.

• Our bandwidth is 20MHz. The largest bandwidth for

deployment of LTE. LTE Advance can do more than 20MHz but

the technology is till under-construction.

3. FREQUENCY BAND AND BANDWIDTH

CYBERSPACE LTE

• Cyberspace currently has three types of devices, MiFi, Indoor

terminal and outdoor terminal.

• The modems have two parts inside by design;

• A. the LTE WAN – connects to the LTE network and gets public

IP address.

• B. the WiFi – connects devices together in WLAN and assigns a

local IP via its inbuilt DHCP.

4. TERMINALS (UE)

CYBERSPACE LTE

• The Huawei MiFi (Model E5776s-420) can support 10 connected WiFi Users

• It has in-built battery that can last over 3 hours in active use and more when idle.

• The battery is rechargeable via its USB port on a computer or its adapter.

• It very portable and can be carried about.

• It is class-4 LTE UE device with 2X2 MIMO transmission system.

4. TERMINALS – MIFI

CYBERSPACE LTE

• The Huawei Indoor CPE (Model B5142 ) can support 30 connected

WiFi Users

• It is currently used for internet deployment for clients.

• It has a better gain than MiFi, but not as much as outdoor. It also has

2 RJ-45 ports for LAN connections.

• It is class-4 LTE UE device with 2X2 MIMO transmission system.

• Default log-in details;

4. TERMINALS – INDOOR TERMINAL

CYBERSPACE LTE

• The Huawei Outdoor (Model B2268 H/S) can support 15 connected WiFi Users per SSID. 2 SSID’s can be configured.

• It has two RJ-45 ports for LAN connections.

• It can do L2TP for layer-2 trunking function. It is currently used by enterprise clients. It has more gains and can work at far distances from the eNodeB.

• It is class-4 LTE UE device with 2X2 MIMO transmission system.

• Default log-in details;
