The government is seeking quotes for the acquisition of two portable, multi-band tactical software-defined radios for ground-to-air voice communications at Sheppard AFB, TX. The radios must be ruggedized to MIL-STD-810, support AES-256 encryption, and be interoperable with military and civilian aircraft networks. This requirement is a total small business set-aside, with the applicable NAICS code size standard of 1,250 employees. Funds are not currently available, so no award will be made until funding is secured, and the government reserves the right to cancel the solicitation.
