18. Exalt – Ahead of the Curve Again!
FCC approves 80 MHz channels
at 11 GHz!
Double the backhaul
capacity for the
same CAPEX!

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

24. Customer Case Study
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.
 Challenges
 Replace T1 lines to eliminate recurring
monthly charges
 Rapidly increase network capacity for
critical applications
 Minimize network latency for public
safety radio and VoIP applications
“If we want more bandwidth it’s just a

25. Customer Case Study
South Texas Electric Cooperative (STEC)
STEC, headquartered in Nursery, Texas
provides wholesale electrical power to eight
member cooperatives serving more than
150,000 members in 33 South Texas counties.
STEC generates power from a variety of
fuels, including natural gas, diesel and hydro-
electric.
