EF Johnson Technologies, Inc. has enhanced its ES Series of Project 25 compliant mobile and portable radios with Project 25 Packet Data and many other new features. Data in a land mobile radio opens up new applications for first responders. For example, the ability of a police officer to use a computer in their vehicle to run NCIC queries or get visuals and warrants could make the difference in an emergency. EF Johnson has also introduced Over-the-Air-Programming (OTAP) enabling officers to provision new radio personalities without having to send the radios to a service shop. The radios are programmed over the air, which saves considerable time. The new P25 Conventional features include an Out of Range indicator that transmits a P25 Data beacon at regular intervals to alert the radio that it is out of range, and automatic registration that registers a radio on the network when it moves from site to site.
