Kenwood plans P25 VHF radios

Kenwood Communications plans to introduce Project 25-compliant VHF portable and mobile radios. Portable handsets are slated for October 2004 delivery, while mobile radios are scheduled to be available in first quarter 2005. Three types of portable handsets will be available: a no-keypad, no-display version, a version with keypad and full display, and an assignable four-button version with full display. Each handset offers 512 channels, FM analog and P25 digital (conventional and trunked) capability and operates over the full spectrum range from 136 MHz to 174 MHz. The mobile radios will be based on the same platform as Kenwood's 90 Series radio. Mounting brackets, speaker microphone and interconnection cables will remain the same, the company said. The VHF version adds to the company's 800 MHz P25 offering.

Radio Waves adds 23 GHz antenna

Radio Waves introduced the Discriminator, a one-foot diameter antenna that operates in the 23 GHz band. The antenna has first side lobes 23 dB down from the main beam, which “greatly reduces interference” from other microwave transmitters when co-location is required, the company said. The antenna also meets FCC Category A requirements. Typically, operators in the U.S. need to utilize a two-foot antenna to meet category A in the 23 GHz band, Radio Waves said, adding that the lower profile reduces costs and improves aesthetics.

Interact public-safety portal enables data access

InterAct Public Safety Systems has unveiled its Public Safety Portal, which enables public-safety agencies using incompatible systems to access and view each other's data by converting the data to the Global Justice XML Data Model developed by the U.S. Department of Justice. The platform also converts radio frequency signals transmitted from an officer's in-vehicle laptop to Internet protocol format to allow interoperability between public-safety agencies using disparate systems. Data can be transmitted using a simple wireless air card, which enables transmission of still photos, or via an 802.11 wireless broadband connection, which enables the transmission of streaming video.
