New SRW waveform set to increase range, reduce spectrum use

27 January 2017

Harris is developing a new narrowband capability for the Soldier Radio Waveform (SRW) in service with the US military.

At present wideband SRW is used to meet higher bandwidth requirements, such as for video and images, over shorter point-to-point distances. The narrowband mode of SRW will extend point-to-point ranges, provide electronic counter-countermeasures, and enhance network scalability, according to a Harris statement.

As many US forces operate in VHF with 25 KHz waveforms, they are used to the very long ranges across different terrains, Jeffrey Kroon, director of radio product management and innovation for Harris, told IHS Jane's .

"They have traditionally been doing voice and maybe a little bit of situational awareness traffic or location information traffic, [but they are] not accustomed to having a lot of data and networks," he said.
