AVIAT WTM 6000 OVERVIEW

ALL- IP LONG HAUL TRUNKING

WIRELESS TRANSMISSION PLATFORM

NOVEMBER 21, 2012

Long Haul Wireless Transmission or ‘Trunking’

• Wireless remains the only medium to enable many operators to deploy nation-wide networks

• Provides backbone network where fiber is not available, too expensive, fiber is not available, too expensive, or not secure

• Spans difficult terrain over long distances in challenging environments

Wireless Trunking Features

• High capacity• Multi-gigabit throughput

• Reliable• Paths can be engineered for 99.999% availability

• Long distance• A single link can span 100 miles, even over water.

Chains of links can cover thousands of miles Chains of links can cover thousands of miles across a continent

• Fast to deploy• A national backbone network can be established

in less than a year

• Common infrastructure• Shares the same towers as GSM/3G/WiMAX

networks

Designed for Maximum Trunking Performance

• Designed for highest level of performance and protection, not adapted from a split-mount product

• Dual plane propagation and equipment protection architecture

• Wide ATPC dynamic range (Manual TPC • Wide ATPC dynamic range (Manual TPC available)

• In-Phase (IP) combiner type Space Diversity w/Automatic Static and Dynamic DADE

• Errorless/hitless N+1 Radio protection switching (RPS) for carrier grade transmission

NOVEMBER 20126 AVIAT NETWORKS |

Industry's highest rack density

• 16 radio channels in a single sub-rack

• Support for M+0, N+1 Terminal or Repeater and (M+1/N+1) Terminal, ACAP/ACCP/CCDP

• Purpose-designed for all indoor installation trunking applications

• Other competing radios are adapted from access-type split-mount designs

• No cable interconnections between baseband, transceiver modules and branching unit

• Very low power consumption

Adaptive Modulation

• WTM 6000 introduces 256QAM Adaptive Modulation (AM) on a trunking radio for the first time

• Dynamically varies link modulation depending upon path conditions

• Allows use of 256QAM for higher • Allows use of 256QAM for higher throughput, with little degradation of path performance or length

• Reduces costs - smaller antennas, less tower loading

GE-SW “Port” Protection in a card, 1 or 2 per shelf

• GE-SW card supports 2 types of port protection

1. L2LA: Using Layer 2 Link Aggregation function inside GE-SW

• When Port 1 fails, Port 2 can handle the packet data to/from 8 x GE-ADAPT cards (Up to 1 x 1GbE)

• Note: Both of Port 1 & 2 are in normal state, the total throughput of line side is up to 2 x 1GbE.

GE-SWRadio

throughput of line side is up to 2 x 1GbE.

2. L2LA: Spanning Tree Protocol, STP/RSTP

• GE-SW always selects Port 1 or Port 2 to handle the packet data to/from 8 x GE-ADAPT cards. The total throughput of line side is up to 1 x 1GbE, in this case.

• Selection from above two types is an user configurable parameter on GE-SW
