Comrex Version Security Concerns and Firmware Fixes



Comrex Connect Modems

Cellular wireless data connections like 3G and 4G LTE have redefined the way remote broadcasts are done. In particular, USB cellular modems make connecting to these networks fast and simple. But the number of USB cellular data devices offered by cell phone providers is dramatically decreasing in favor of cellular Wi-Fi Hotspots. Additionally, many of the off-the-shelf modems offered by carriers are not designed to meet the rigorous demands of the 24/7 news cycle.

Comrex designed the Comrex Connect Modem to support the unique needs of remote broadcasters. A high-powered, industrial strength 4G/LTE modem, the Connect Modem is also 3G compatible. Outfitted with a high-gain antenna, the Connect Modem is more powerful than most USB data modems available on the market, to handle the heavy data load of an IP audio broadcast.

The Connect Modem INITIALLY came in four varieties to support connections to Verizon, AT&T, International (for outside of US), and CJ (for use in China, Japan, Taiwan, Korea, and Brazil) networks, and was PTCRB and carrier certified to meet all necessary regulations.

As of July 2020, the ACCESS Connect Modem comes in three varieties (VZW/ATT, International, and CJ). The NEW Connect Modem for ACCESS can work with ACCESS 2USB, ACCESS NX, ACCESS Rack, ACCESS NX Rack, ACCESS MultiRack, and BRIC-Link II (when used with HotSwap).

VZW/ATT Comrex Connect modems purchased after 7/1/2020 will only work on units with FW 4.5p3 or higher.
