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.

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.
