As the only carrier-class, multi-service wireless Ethernet bridges for the licensed 4.9GHz public safety band, the EX-4.9r and EX-4.9r-c from Exalt provide highly reliable and secure communications for emergency response and public safety communications. The EX-4.9r and EX-4.9r-c provide up to 55Mbps of Ethernet capacity plus four T1/E1 interfaces to enable PBX or trunk line interconnectivity and seamless migration path from TDM to native IP-based services. Specifically, they provide a future-proof solution for implementing VoIP and P25 migration strategies. |
These systems are available with integral antenna or dual type-N connectorized with software selectable polarization switching for flexible external antenna mounting options.
The EX-4.9r and EX-4.9r-c provide affordable multi-service performance and maximum reliability in a system designed to meet the stringent requirements of telecommunications carriers. In comparison, most 4.9GHz solutions are based on Wi-Fi OFDM, which is best-effort technology designed for consumer applications with unpredictable throughput, reliability, and latency. Furthermore, Exalt does not require external T1/E1 multiplexers or sacrifice latency and performance by converting TDM connections to IP.
Exalt delivers reliable, sustained Ethernet and T1/E1 capacity over longer distances in the most adverse environmental and path conditions and at the lowest cost per megabit-mile available today!

** Firmware option required
*** Integrated antenna (EX-4.9r) and external antenna versions (EX-4.9r-c) both have user-selectable polarization switching.
**** The figure listed is the actual aggregate user throughput, maximum, as measured at layer 2. T1 circuits may be enabled one at a time, as needed, and subtract 3.1Mbps (1.544Mbps full-duplex) from the aggregate user throughput. Some combinations of frame size, link distance, T1 enabling, bandwidth, mode and desired latency will result in reduced maximum aggregate throughput. See your Exalt Communications representative for details.
**** Firmware upgrade required |
