M/A-COM announced during this week’s Association of Public-Safety Communications Officials conference in Montreal that it has added Text Link, a text-messaging application, to its OpenSky network. The company said the service is similar to the short message service (SMS) offered by commercial wireless carriers, and would enable first responders to share real-time intelligence and communications during incidents.

In addition, the company said it would upgrade its M7100IP and P7100IP P25 portable and mobile radios by adding AES encryption. The radios already feature DES OFB encryption.

Finally, M/A-COM announced that a recent series of customer tests indicated its P7100IP radios are compatible with other commercially available P25 radios—including those manufactured by Motorola, Thales, Datron and Relm—in three broadcast modes: P25 conventional common air interface (CAI) unencrypted, P25 CAI with DES encryption and P25 CAI with AES encryption.
