Expedience® Mobile Subscriber Unit

Mobile Subscriber Unit

High performance mobile solution for wireless broadband access

Motorola's Expedience Mobile Subscriber Unit delivers flexible, high-speed connectivity for nomadic vehicular wireless broadband access. Performance in the field and on the bottom line.

Motorola's Expedience Mobile Subscriber Unit (MSU) is a robust broadband wireless access modem intended for mobile market applications such as public safety and transportation. It is a true Plug & Play Ethernet device, requiring no special drivers to be installed in an interfacing computer. Particularly important for Public Safety applications is the compatibility with standard IP software appli­cations, eliminating the need to purchase special proprietary solutions to run on a mobile data plat­form. The MSU is also well suited for backhaul of a temporary emergency LAN that can be set up for first responders in emergency situations. The MSU incorporates automatic adaptive modulation for increased throughput and network capacity. Applications supported include data, VoIP, and streaming video.

The MSU is designed for automotive trunk mount­ing. It is operable over a standard vehicular voltage range of 11.7-15.9 VDC and a temperature range of -40° to +60° Celsius.

The unit functions as an Ethernet bridge (Layer 2) device, and is practical for single host or LAN appli­cations interfacing a standard Ethernet 10base-T RJ-45 connector. The MSU includes cabling for Ethernet connection and DC power feed, and is available with either a magnetic mount or through-hole mount antenna.
