Vendors continue to provide for public safety

Two-way radios are critical to public-safety communications and have been used for decades to help police officers, firefighters and paramedics share information during emergency incidents. The vendor community continues to develop new technologies to assist the mission of first responders, from handheld radios to Bluetooth microphones. The following is a sampling of the market's offerings. — MARY ROSE ROBERTS

PA SYSTEM, RADIO MODEM

Ritron launched a VHF/UHF wireless PA system — the Loud Mouth — that eliminates the need to rewire an entire facility and permits PA communication in areas where long distances or obstructions would otherwise make wired connections inefficient. The company also unveiled the DTXM radio modem, a wireless modem that operates on the licensed land-mobile frequency bands at VHF, UHF and 220 MHz.

PORTABLE RADIO, BASE STATION

Tyco Electronics Wireless Systems offers the P5400 portable radio in 800 MHz, VHF and UHF frequencies. Operating modes include OpenSky trunking, Project 25 trunked or conventional modes, Enhanced Digital Access Communications System (EDACS) or ProVoice trunked modes, and analog conventional mode. The P5300 portable radio offers similar features in the 900 MHz frequency band, including Tyco Electronics' OpenSky trunking, EDACS and analog conventional mode. Both the P5300 and P5400 portable radios are rated as intrinsically safe.

The company's MASTR V 700 P25T base station provides secure digital trunked communications for mission-critical applications and supports the P25 Trunked Common Air Interface. The MASTR V 700 P25T incorporates P25 digital voice and data using a digital signal processor for maximum design versatility. P25 digital voice is translated through an on-board voice encoder/decoder in the station to allow immediate access to P25 communications through the user's existing network. It is software upgradeable to P25 Phase 2, supports linear simulcast and allows as many as eight channels per cabinet.
