Wireless Matrix MBS2 User Guide Document MBUD-0086v1b MBS2 User Guide INTRODUCTION This guide explains procedures for using the Wireless Matrix Mobile Base Station 2 (MBS2) modem as installed on a vehicle for data communications. Technical Support Technical questions should be directed to the Customer Care team at (866) 456-7522.
Wireless Matrix MBS2 User Guide Document MBUD-0086v1b The MBS2 satellite radio emits radio frequency (RF) energy when transmitting. The MBS2 must be installed in a manner that provides a minimum separation distance of 20 cm or more between the antenna and persons to satisfy FCC RF exposure requirements for mobile transmitting devices. Operators should maintain a safe distance from radio when transmitting. Wireless Matrix recommends installing the MBS2 device with a safe distance of 51 cm or more.
Wireless Matrix MBS2 User Guide Document MBUD-0086v1b GENERAL DESCRIPTION MBS2 Unit The MBS2 is comprised of an Interactive Satellite Packet Data (ISPD) modem, a General Packet Radio Service (GPRS) terrestrial wireless modem, and an 802.11b modem, well as associated antennas. It also supports a Global Positioning Service (GPS) receiver, as well as a Keyfob receiver for Personal Alert. The MBS2 is pictured in Figure 1 and Figure 2.
Wireless Matrix MBS2 User Guide Document MBUD-0086v1b Figure 2: MBS2 Front Oblique View without Covering The MBS2 is typically connected to a peripheral computer called the Client Side Computer (CSC) using a tethered serial port connection and/or an untethered 802.11b connection. The CSC can be a standard laptop or other computing device. The user application and associated middleware resides on the CSC. The MBS2 is capable of supporting some user applications.

Wireless Matrix MBS2 User Guide Document MBUD-0086v1b Satellite Modem The L-band satellite modem is used to communicate at L-band via the ISPD network. The modem is provided with an omni-directional cross-dipole antenna. The satellite modem is designed and manufactured by Wireless Matrix. GPRS Modem A GPRS terrestrial wireless modem is used to communicate on the AT&T Wireless Services (AWS) GPRS network. The GPRS modem is a Motorola model G20 OEM module. A monopole antenna is used with this modem. 802.
Wireless Matrix MBS2 User Guide Document MBUD-0086v1b Keyfob Receiver For Alert and Personal Alert features, the MBS2 uses a 315 MHz keyfob receiver and inverted-F antenna. An external keyfob transmitter is also provided. FEATURES Multi-Network Routing The Multi-Network Routing (MNR) function enables the MBS2 to send communications over the best available network, as determined by a “Primary Network” setting and the coverage situation.
Wireless Matrix MBS2 User Guide Document MBUD-0086v1b When the MBS2 is not in the coverage area of any AP, it will forward packets received from the serial connection to the WIPG, and the WIPG will route packets to the application host. The returned traffic from host side will reach the CSC in the reverse fashion. See Figure 4 for a graphical description. This ability is achieved using Mobile IP, as well as the MBS2’s 802.11b device in infrastructure mode.
Wireless Matrix MBS2 User Guide Document MBUD-0086v1b Internet Protocols Support The MBS2 is capable of supporting the following IP-based protocols: • • • • • DHCP client and server on all MBS2 IP-capable interfaces Standard IP routing between all MBS2 IP-capable interfaces PPP over the Serial Interface ICMP Ping from the MBS2 to the user-specified address Telnet and TFTP firmware downloads from all MBS2 IP-capable interfaces User Applications The MBS2 supports multiple User Applications residing in its

A minimum throughput is not guaranteed.
Wireless Matrix MBS2 User Guide Document MBUD-0086v1b To verify the MBS2 unit is operational; ensure the following items: 1. Move the vehicle to an area where there are no obstructions to the southern exposure for the Wireless Matrix MBS2. 2. Check the cable connections to the MBS2 and verify it is securely connected. MBS2 Operation The operation of the MBS2 is passive. It will activate in order to send data, which is triggered by use of an application on the Client Side Computer for such purposes.
