NextGen CNS Test Bed

• Sensis Corporation MLAT surveillance (18 RUs) and 802.11fixed wireless comm network

– Installed at 3 Cleveland airports (CLE, BKL, LPR) and NASA Glenn Research Center

– Operate in unlicensed 2.4 GHz band• ITT Corporation in process of installing

802.16 mobile and fixed wireless comm network at CLE and GRC

– Base stations (2) and CPE (6)– GRC holds 7 licenses in 5.1 GHz band

• Modifications planned for GRC’s “THEVAN” and potential use of S-3 or T-34 for emulation of transportable assets and mobile users

Network Partitioning by ServiceArchitecture Example

QoS & Security Service Levels for:

• Network Control• Voice over IP• High Priority

• Special Projects• General Purpose

Networks are logically partitioned.

Many logical networks share a common physical

infrastructure.
