A Canadian-developed tactical software-defined radio used by the U.S. Army, U.S. Marine Corps, and a number other countries, the AN/GRC-245, with the current version called the Enhanced High Capacity Line-of-Sight Radio (HCLOS), replaces the AN/GRC-226 radios in the AN/TRC-190 family of transmission assemblages.[1] It is part of the Area Common User System Modernization (ACUS-Mod) variation on the Warfighter Information Network–Tactical (WIN-T) and JNN architecture, more compatible with the restructuring of the United States Army. The equipment has been in U.S. Army service since 2000. It is backwards-compatible with the AN/GRC-226, used in the Mobile Subscriber Equipment (MSE).

Configuration

There are three major variants:

  • AN/GRC-245 Enhanced Software Communications Architecture (SCA) radio
  • AN/GRC-245 high power radio
  • AN/GRC-245 Band IV radio

It operates in three freqency ranges:

  • 225 to 400 MHz NATO Band I
  • 1,350 to 2,690 MHz Band III+
  • 4,400 to 5,000 MHz Band IV; this is upgradable to support IEEE 802.16 WiMax long-range wireless LAN technology[2], which also can provide cellular telephony

The initial version had 16 Mbps of bandwidth, growing to 34 Mbps in a Joint Tactical Radio System-compatible mode.

International use

It was developed by Canadian Communication Research Center (CRC) in concert with Ultra Electronics.[3] In addition, it is part of the UK Theatre Wide Communications Network in the Cormorant project, and the follow-on Falcon system. the AN/GRC-245 is also to be used by Taiwan. It has also been sold to India and Jordan. [4]
