AB9400 Product Overview

3 AB9400: Point-to-Point and PMP on One Radio Platform

AB9400: Point-to-Point and PMP on One Radio Platform

Point-to-Point and PMP use the same equipment and are managed by the same EMS

Key benefits: leverage common training, sparing, network management, etc.

All Hughes advantages apply: Frequency reuse, even adjacent channels Frequency changes on-the-fly Mix of traffic E1, ATM, IP

4 Key Features

Key Features

Low startup investment with single sector HT Linear expansion: match investment with revenue Low operational costs: automatic installation, etc Highest efficiency with 16-QAM Flexible architecture: ATM, TDM and IP transport with QoS (Flexible bandwidth control) Optimized for cellular backhaul IP/LAN for SMEs Long Range: 5.7km for 99.99% Rain zone K Carrier grade EMS (Sun-Unix) Bottom line: lowest CapEx, lowest OpEx

5 High Spectral Efficiency with Multi-Modulation

High Spectral Efficiency with Multi-Modulation

Higher capacity using 16-QAM: 30 Mbps 3.2 bps/Hz (2.4 bps/Hz payload) Higher range and availability using QPSK: 15 Mbps 1.6 bps/Hz (1.2 bps/Hz payload) Hub radio supports remotes using both modes (slot by slot), optimizing system capacity and range

6 Hughes’ Patented Multi-Modulation Optimizes Range and Capacity

Hughes’ Patented Multi-Modulation Optimizes Range and Capacity

Hub

AB9400 Hub/Base Station Supports Terminals with 16QAM and QPSK Simultaneously on a site-by-site basis

DBA The HT is the controller of the DBA algorithm. The HT assigns timeslots based on demand and priority as defined by the QoS parameters on a per VP/VC basis. Each RT can receive up to the full air bandwidth.

8 Hughes AB9400 Advantages

Hughes AB9400 Advantages

TDMA architecture is more economical than FDMA, lower capex and opex AB9400 “first-link cost” [initial base station and one remote terminal] is similar to point-to-point microwave price AB9400 Base Station has ATM, NxE1, + 100BaseT interfaces, permitting migration of traffic from E1 to ATM to IP with no hardware swapout Higher Remote Terminal capacity Some FDMA products limited to 8 Mbps/4xE1 AB9400 Remote Terminal supports 4-12 E1s, up to 29 Mbps ATM throughput, 20-30 Mbps IP throughput AB9400 TDMA system allows dynamic bandwidth allocation (DBA) among multiple Remote Terminals DBA is vital for concentrating backhaul traffic from HSDPA/UMTS cell sites, allows oversubscription of 3G data carriers, reduces transmission costs at cell sites and upstream FDMA systems cannot share bandwidth among remote terminals AB9400 has more robust ATM and IP services & features

9 Hub/Base Station Costs

Hub/Base Station Costs

TDMA Base Station: Lower Capex & Opex

FDMA Base Station

4 TDMA Radios (120 Mbps Capacity with 4 Radios in 1/3 Rack

24 FDMA Modems

4-Sector Hub for 24 Remotes

FDMA Hub/Base Station: Multiple module types & multiple modules per radio Requires additional modem for each Remote Terminal Requires site visit to add/configure modem for incremental Remote Terminal Range decreases as Remotes are added to multi-carrier transmitter

TDMA Hub/Base Station: Only one module (circuit pack) per radio Each radio supports >16 Remote Terminals No hub site visit required for incremental Remote Number of remotes does not affect range with single-carrier TDMA

10 AB9400 Superior Redundancy

AB9400 Superior Redundancy

Protection available for ATM, IP, and E1 interfaces at hub/base stations and remotes Hub radios can be 1:0, 1:1, or 1:N redundant Remote radios can be 1:0 or 1:1 protected

11 TDMA Enables Active Redundancy for Hub/Base Stations

TDMA Enables Active Redundancy for Hub/Base Stations

Backup hub radio transmits test burst in maintenance time slot Remote Terminals report signal strength of primary and backup radios Alarm generated for backup unit failure or degradation Continuous “Active Redundancy Testing” avoids switchover to failed backup units, reduces system outages FDMA systems not capable of active redundancy

12 2/3G Capacity Requirements

2/3G Capacity Requirements

Cell site with 2G+3G will require 5-10 E1s AB9400 Remote Terminal equipped with 4, 8, or 12 E1s About 40 percent of Hughes PMP deployments for cellular operators are 8xE1 or 12xE1 RTs today Some PMP suppliers offer maximum 4 E1s, not sufficient for large cells or 2+3G cells

31 3G Requires ATM Today

3G Requires ATM Today

Today’s 3G Node B requires ATM transport: FDMA Base Station requires external mux to aggregate E1s with IMA onto E3 or STM-1 [extra capex & opex] AB9400 Base Station/Hub multiplexes ATM traffic from multiple Remote Terminals onto E3 or STM-1 ATM channel Some FDMA Remote Terminals limited to total throughput of 8 Mbps [4xE1 or 8 Mbps of LAN] AB9400 Remote Terminal supports total throughput of 30 Mbps [4-12xE1, plus E3 or STM-1 ATM, plus 10/100BaseT]

FDD UMTS + HSDPA = ATM Transport

Future 3G Cells Will Require IP

3G migrating to IP transport: TDD UMTS today – T-Mobile Czech, Orange Slovakia, etc. Future HSDPA overlay base stations 3G cells with 2-4 Mbps user traffic per sector, need 6-12 Mbps backhaul FDMA Base Station requires expansion unit for IP traffic [extra cost] Every AB9400 Base Station/Hub radio today supports 100BaseT interface for IP traffic FDMA Remote Terminal limited to maximum 8 Mbps [insufficient capacity] AB9400 Remote Terminal supports total throughput 20-30 Mbps IP traffic depending on packet size
