This document discusses backhaul considerations for critical infrastructure applications. It describes how wireless backhaul can be used for video surveillance, radio communications, and SCADA systems. Key considerations for critical infrastructure backhaul include supporting both TDM and Ethernet, using licensed frequency bands for security, ruggedized equipment, long product warranties, and local technical support. The document introduces Exalt Communications and their portfolio of point-to-point wireless backhaul radios, which operate in frequency bands between 2-43 GHz and support throughput from 100 Mbps to over 1 Gbps. Their product lines include the ExtendAir, ExploreAir, ExtremeAir, and EX platforms.

19. See the Difference in Maximum Data Throughput
Exalt ExploreAir® and ExtremeAir® systems provide twice
the single-carrier capacity achievable before the ruling –
without the need to buy additional hardware.
*Throughput based on theoretical maximum over the air data rates.
ExploreAir, ExploreAir LR, ExploreAir HP, and ExtremeAir radios support the
80 MHz channels now available in the 11 GHz frequency band
ExploreAir LR, also supports the 60 MHz channels now available in the 6 GHz Lower band

City of Garland, Texas
Garland, Texas is home to more than 200,000
residents. The City’s network links 30-plus
facilities, and supports computer-aided police/fire
dispatch systems, public safety radio traffic, VoIP
systems and office productivity applications.
