But radios carry their share of headaches, as well. Chief among these is that communications can be monitored by any hobbyist with a scanner. The last thing public safety workers need is the sudden appearance of curious onlookers at the scene of an emergency. And police know that any communications may be monitored by the very people they're trying to apprehend. Not only do radios compromise security, they compromise accuracy, as well.
Dispatchers often find themselves having to repeat or confirm information.
And while a dispatcher and field unit clarify the difference between Senate Street and Synott Street, all other communications are placed on hold. Using wireless data eliminates this confusion by placing directions or, better yet, an interactive map right in front of the driver. And, since data can be encrypted, all communications are secure. Everyone can access information on demand, be it medical records, DMV reports, warrant information or routing instructions. Officers can be proactive, checking vehicles or suspicious persons without burdening a dispatcher.
