Base stations, subscriber units, bridges

Proxim Wireless launched its Tsunami MP.11 HS line of base stations, subscriber units and bridges targeted to the government, utility and enterprise markets. The product line meets FIPS 140-2 Level 2 standards for point-to-point and point-to-multipoint products in the 5.1-5.95 GHz, 4.9 GHz, 2.4 GHz, and 1.8 GHz frequency bands, as well as the AES-256 encryption standard, the company said.

Wireless gateway

In Motion Technology released the onBoard Mobile Gateway LE, a multi-network wireless communications platform that supports broadband applications, including video. The gateway switches between cellular, municipal Wi-Fi and other wireless networks. It also creates a vehicle area network for all on-board data communications, including laptop applications, surveillance cameras, ticket writing and printing devices, radio frequency identification technology, fingerprint scanners, and other law enforcement tools. These devices remain connected in and around the vehicle, so officers can receive dispatch information and access databases without being tied to the vehicle, according to In Motion.

Mobile digital video recorder

Safety Vision introduced the PatrolRecorder 4C mobile digital video recorder. It includes a solid-state, flash-memory hard drive or a mobile, removable hard drive and is capable of video transfer over a wireless network, according to the company. It can record up to 24 frames per second at a standard resolution of 720 × 480 pixels. It also includes a GPS system that tracks the location of a recorded event and maps the data on the company's GUI software system.

Power meters

Boonton Electronics introduced the model 4542 and 4541 RF power meters. The 4541 offers one measurement channel, while the 4542 offers two channels. Both meters support GSM, EDGE, CDMA, EV-DO, Wi-Fi and WiMax technologies, among others. They also support sensors up to 110 GHz, the company said.

TETRA base station

Tyco Electronics' M/A-COM introduced the MASTR IV terrestrial trunked radio (TETRA) base station, which operates on the 380, 410 and 450 MHz frequency bands. It is scalable from the standard four carriers to an optional eight carriers, according to the company.

Multisite IP networking

Kenwood's NEXEDGE 12.5 and 6.25 kHz VHF and UHF digital trunked systems are now capable of multisite IP networking to link up to 16 trunked sites for wide-area calling and auto-roaming capabilities. A multisite flash option creates scalable networks over existing IT assets, private microwave, spread-spectrum links or carrier bandwidth using off-the-shelf 10/100 Base-T Ethernet switches and routers, while the platform's 60,000 group and unit ID capacity provides flexibility for shared systems and large multiuser fleets, according to the company.

Premium operations include the choice of transmission/message trunking per site, group/unit/ESN validation, late entry and prioritized call queuing with pre-emption. The platform's system manager provides operators with secure site provisioning and monitoring capability through either a dial-up or IP connection, Kenwood said.

Other features include Over-the-Air Alias — which provides Caller ID without subscriber preprogramming — group call, individual private call, encryption, status/text messaging and GPS location with voice.

Direction-finding antennas

Astron Wireless Technology's HESA (high efficiency, sensitivity, accuracy) direction-finding antenna system now operates over a range from 2 MHz to 18 GHz for all applications (previously it ran only from 2 MHz to 3 GHz). The system is used by the military for RF surveillance, monitoring and jamming applications, and configures multiple antenna elements in a small form factor, the company said.
