Magnum Edge Switch Networks LAPD Cruisers


The Los Angeles Police Department (LAPD) is the third largest police department in the United States with over 10,000 officers responsible for a 500 mile, four million person area.

With such a large area and limited officers, increasingly the LAPD is turning toward mobile communication systems. Police need to be able to retrieve data such as personal and vehicle information via police headquarters and other government databases. Additionally, the interchange of data among various police officers in field cruisers is very efficient.

Industrial Ethernet Edge Switches from GarrettCom were selected for LAPD’s hardened mobile communication system. The six-port Magnum ES42 Edge Switches easily met LAPD’s temperature requirements, and the switches had a long record of fieldproven reliability. Each Magnum Edge Switch was mounted in the rear of a LAPD cruiser where it enabled a communication system among the different cruisers as well as to police headquarters. Each switch connected to a hardened trunk-mounted computer as well as to an in-vehicle laptop. Each 100Mb/s ES42 also networked an on-board video camera.

LAPD has also considered the PES42 Edge Switch that offers up to four PoE ports for possible connection to PoE-powered video cameras. Currently the ES42 Edge Switches are powered via the cruisers’ 12VDC car batteries. Adding a DC-to-DC power converter (12VDC to 48VDC) supply would not only enable networking of the PoE cameras but could also help filter out the electrical noise from the charging and discharging of the vehicle batteries. Magnum Edge Switch models are available with 12VDC, 24VDC, -48VDC, and AC power options. LAPD has found the compact, ruggedized Edge Switches to be a good fit for their officers in-vehicle networking needs and plans to continue to deploy the Magnum Edge Switches.
