Wireless Matrix Proprietary and Confidential 5/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 GENERAL DESCRIPTION MBS2-LP Unit The MBS2-LP is comprised of an Interactive Satellite Packet Data (ISPD) modem, a General Packet Radio Service/Enhanced Data-rate for GSM Evolution (GPRS/EDGE) cellular data 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-LP is pictured in Figure 1. Figure 1: MBS2-LP Front View with Covering The MBS2-LP 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-LP is capable of supporting some user applications. The CSC communicates over the Wireless Matrix Wide Area Wireless (WAW) Network via the MBS2-LP. At the link layer, PPP or the Modem Interface Protocol (MIP) can be used between the CSC and MBS2-LP. At the transport layer, the CSC can use UDP to communicate with a Customer Host via the WAW Network. WAW Network The WAW Network, shown in Figure 2, consists of a Data Hub, satellite and terrestrial wireless networks, and the MBS2-LP unit. WAW is an enterprise solution wireless data service between remote modems and Customer Host computers, offering seamless coverage with a single point of connection to the network. This packet-data service can be routed over either Mobile Satellite Venture’s MSAT-2 satellite or the GPRS/EDGE network Customer Hosts connect to the Data Hub via Frame, VPN, or leased-line. The Data Hub consists of: • • • Network Operations Support System (NOSS): manages the modems on the WAW network Wireless IP Gateway (WIPG) that connects to the ISPD and GPRS/EDGE networks and controls data sent between the Customer Hosts and MBS2-LPs. ISPD equipment Wireless Matrix Proprietary and Confidential 6/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 The Wireless Matrix-owned and operated ISPD Network consists: • • • • Primary Data Hub equipment located at Wireless Matrix in Reston, Virginia Secondary Data Hub equipment located in Ashburn, Virginia Communications Ground Segment (CGS) located at Mobile Satellite Ventures in Reston, Virginia MSAT-2 geostationary satellite. MSAT-2 covers the United States and its coastal waters as well as Canada On the client side, a CSC device connects to the MBS2-LP. The MBS2-LP routes messages over the Wireless Matrix ISPD Satellite network or the GPRS/EDGE network, depending on which network the MBS2-LP determines to be the “Active Network”. The MBS2-LP is also responsible for notifying the WIPG when its Active Network changes.

It has a dedicated port number that can be accessed by external entities to make configuration changes to and queries about the status of the MBS2-LP and wireless network availability. The command server is accessible by Customer Hosts, client applications, CSCs, and the WAW Network Operational Support System (NOSS) by using UDP. Some of the key features of the command server are as follows: • • • • Initiate the MBS2-LP commissioning process Send and receive MBS2-LP Management messages to and from the NOSS Provide control of and access to information about the various components within the MBS2-LP (GPRS/EDGE and Satellite modems, etc.) Monitor status of MBS2-LP and its components, and provide status information to the NOSS or CSC upon request 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/EDGE Modem A GPRS/EDGE terrestrial wireless modem is used to communicate on GSM networks. The GPRS/EDGE modem is a Motorola model G24E GPRS/EDGE OEM module (MS Class 10). A monopole antenna is used with this modem. 802.11b Modem The MBS2-LP uses an 802.11b WLAN modem to connect to the CSC wirelessly. By doing so, it extends the range of a CSC user to several hundred feet from the MBS2-LP. This “Wireless Tether” also provides good in-building penetration, exceeding 300 feet with a Itronix GoBook laptop or similar. Outdoor line of sight distances have been tested in excess of 1000 feet with similar client devices. The Wireless Tether supports all of the same functionality that a standard serial port connection supports. The MBS2-LP is capable of routing the communications of multiple CSCs via the WAW. Also, a CSC using one MBS2-LP may “Roam” to another MBS2-LP and use the latter to communicate with the WAW network. With this flexible scheme, the MBS2-LP is truly a Base Station that is mobile. The MBS2-LP uses the Cisco Aironet 350 PCMCIA card for 802.11b communications. An elevated dipole antenna is provided. The customer is responsible for providing the CSC with a Wireless Matrix Proprietary and Confidential 8/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 wireless modem card capable of communicating with the Wireless Tether modem and approved by Wireless Matrix. MBS2-LP supports ad-hoc mode for communications with a CSC, or infrastructure mode for communications with an Access Point in an In-Yard Communications situation. The MBS2-LP also has the capability to use the Wireless Tether to communicate with CSCs that use a sleep mode for power conservation. See the Magic Packet section for details. The MBS2-LP is capable of the following security methods: • • • WEP encryption LEAP Authentication EAP-TLS Authentication GPS Receiver The GPS receiver option includes a GPS receiver and a separate patch antenna. The GPS receiver is a Navman Jupiter J20, manufactured by Navman. It measures position with an accuracy of 2.1 meters horizontal, velocity accurate to 0.1 meters/sec, and time accurate typically better than 1 μs. The GPS information can be used by the Wireless Matrix AVL application or the application running on the CSC. Position information can be queried using the gps pos command, or by configuring the device to send NMEA 0183 v2.2 messages. The CSC application can access GPS information through command server primitives (refer to MBS Command Reference Document for details). Keyfob Receiver For Alert and Personal Alert features, the MBS2-LP uses a 315 MHz keyfob receiver and inverted-F antenna. An external keyfob transmitter is also provided. Wireless Matrix Proprietary and Confidential 9/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 FEATURES Multi-Network Routing (MNR) The Multi-Network Routing (MNR) function enables the MBS2-LP to send communications over the best available network, as determined by a “Primary Network” setting and the coverage situation. The routing algorithm is based on a parameter called the “Active Network”, and is explained in the sections below. The MBS2-LP is configured during Commissioning to have a “Primary Network”, or a preferred network. The MBS2-LP will always use the Primary Network as the Active Network when within Primary Network coverage. The Secondary Network will become the Active Network only if no Primary Network coverage is available. For instance, if the Primary Network is satellite, and the MBS2-LP is in satellite coverage, the Active Network for the MBS2-LP is satellite. If the MBS2-LP leaves satellite coverage but is still in terrestrial wireless coverage, the Active Network would become terrestrial. Bandwidth Steering (BWS) Bandwidth Steering provides a second network path via the MBS2, permitting the full speed of the GPRS/EDGE network, as well as providing a more economical path for data-intensive communications. It operates simultaneously with the WAW MNR path. Bandwidth Steering is based on IP routing rules: all traffic destined for one subnet is routed via multi-mode network path, while all other traffic is routed to the Bandwidth Steering network path. Bandwidth Steering is offered as an optional feature, priced separately from the standard multimode service. It enables: • • • Large Emails Web Browsing Large file downloads/uploads Figure 3: Bandwidth Steering Wireless Matrix Proprietary and Confidential 10/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 Active Network (AN) Determination The MBS2-LP periodically evaluates the Satellite and GPRS/EDGE Network coverage and updates its Active Network based on a predefined Active Network Algorithm (not to be confused with the MNR algorithm). In general, if a change in its Active Network occurs, the MBS2-LP will inform the WIPG of the new Active Network value by sending an Active Network Message (ANM), so that the WIPG can use the Active Network for its own MNR algorithm. Magic Packet WAW offers the Magic Packet (MP) feature to conserve battery life on a CSC while maintaining Wireless Tether communications upon demand. Thus, a CSC can enter sleep mode and be awaken by a Magic Packet whenever the Customer Host has data to send to the CSC (provided that the CSC is in WLAN range of the MBS2-LP). In-Yard Access In-yard access provides the ability to send and/or receive data with lower latency, high throughput, and reduced airtime expense by routing the data directly through a Customer-owned In-Yard 802.11 network When the MBS2-LP arrives in an In-Yard district, the MBS2-LP will associate with the AP at the district. On successful association, the CSC sends or receives traffic directly to or from the customer corporate network. As soon as the MBS2-LP leaves the AP WLAN coverage area, it will go back to its original configuration (i.e., WAW IP). When the MBS2-LP 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-LP’s 802.11b device in infrastructure mode.

The IP addresses are assigned and maintained by the WAW Network. WDHCP allows CSCs to associate with any MBS2-LP to gain access to the WAW Network. WDHCP relies on the Wireless Modem Discovery (WMD) protocol: a simple protocol used by client CSCs to query for the availability of MBS2-LPs within their communication range. Once the MBS2-LP is selected, the CSC registers with a WDHCP server in the NOSS, which processes the request and assigns the IP address to the CSC Internet Protocols Support The MBS2-LP is capable of supporting the following IP-based protocols: • • • • • DHCP client and server on all MBS2-LP IP-capable interfaces Standard IP routing between all MBS2-LP IP-capable interfaces PPP over the Serial Interface ICMP Ping from the MBS2-LP to the user-specified address Telnet and TFTP firmware downloads from all MBS2-LP IP-capable interfaces Wireless Matrix Proprietary and Confidential 12/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 Alert and Personal Alert The Alert and Personal Alert features can be used to inform the Customer Host of an important event, such as driver in danger or “man-down” messages. The Customer Host would be able to distinguish between a keyfob or vehicle button activation. The Alert message is generated by the closing of an electrical contact, and the Personal Alert message is generated by a keyfob. The wireless keyfob signal can be received by the MBS at a distance of 150 feet. The message is sent with location information and truck identification by using the Wireless Matrix AVL application. Wireless Matrix Proprietary and Confidential 13/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 MISCELLANEOUS Addressing All components of the WAW system are addressed using IP addressing. Customer Hosts, MBS2-LPs, and CSCs are designated IP addresses in the following subnet range: 10.128.0.1 to 10.254.255.254. From the Customer Host point of view, the CSC IP address may be statically assigned or dynamically assigned using WDHCP. The pool of addresses used for assignment shall be specified by either the Customer or Wireless Matrix personnel. Ports 51000 to 51999 shall be reserved for User Applications residing on the MBS2-LP. Throughput MBS2-LP throughput on the WAW network is almost entirely dependent on the throughput of the underlying ISPD and GPRS/EDGE networks. Raw data rates are known, but actual throughputs are estimated, based on the fact that multiple users share the over-the-air channels. Table 1 lists the data rate information for each network. Type of Data Rate Raw Actual rate ISPD 6.75 kbps 0.3 to 0.6 kbps GPRS/EDGE via MNR 384 kbps 10 to 25 kbps GPRS/EDGE via Bandwidth Steering 384 kbps 70 to 115 kbps Table 1: MBS2-LP Underlying Networks Throughput Comparison Note that since the underlying networks are transparent to the MBS2-LP user in MNR, the actual throughput depends on the current Active Network. A minimum throughput is not guaranteed. Tools Wireless Matrix provides two tools to assist the developer on the WAW system: Wireless Matrix Chat and Communicator. The tools are Open Source license tools distributed in code form. This provides complete visibility for the developer and enables straightforward extensions to the program that the developer may want to add. The Wireless Matrix Chat program was created to provide simple chat sessions over the air from Customer Host to MBS2-LP or from MBS2-LP to MBS2-LP. The Communicator is similar to the On-Board Computer (OBC) application used in the Wireless Matrix X.25 network. It allows an operator to: • Edit and send messages to an arbitrary IP address • Send a file of arbitrary size to an arbitrary IP address • View the text of messages received by the Communicator • Monitor the operational status of the MBS2-LP • Monitor the signal strengths of the networks to which the MBS2-LP is connected • Access the Command Server of the MBS2-LP Wireless Matrix Proprietary and Confidential 14/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 The Communicator user interface is suitable for all types of client devices, including small form factor WinCE handheld and, potentially, Palm devices. It operates on both sides of the WAW (server/host and client/MBS2-LP), so that with a single tool the developer can easily test end-toend communications. On the client side, the interface to the MBS2-LP command server is via the serial port (or wireless tether), and on the Customer Host side the interface to the MBS2-LP command server is over the WAW Network via standard UDP/IP. Wireless Matrix Proprietary and Confidential 15/16 MBS-LP EDGE User Guide Document MBUD-0122v1.0 INSTALLATION OVERVIEW Installation The Wireless Matrix MBS2-LP modem is mounted to a vehicle and wired in order to: • • Draw power from the vehicle to power the unit Connect the unit to a Client Side Computer (CSC) for data transmission/receipt purposes Installation instructions for the MBS2-LP, while not complex, are detailed, and are included in a separate installation manual (MBS2 LP Install Guide, MBUD-0110v1.2, dated 10/17/06). Please consult this manual if you need to install the MBS2-LP unit. To verify the MBS2-LP 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-LP. 2. Check the cable connections to the MBS2-LP and verify it is securely connected. MBS2-LP Operation The operation of the MBS2-LP 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. It will also activate when it receives a remote request (such as when it is polled for vehicle information), or receives data (such as a message from a dispatcher). In addition, because the unit will automatically select the best routing for messages without user intervention, the user does not need to interact with the unit to select a communications method. In this regard, there is no activity that the vehicle operator must undertake with the MBS2-LP unit. Equipment Failure or Damage If the MBS2-LP unit suffers a mechanical failure or is damaged during the course of the program, please notify Customer Care as soon as possible. Equipment that is returned damaged or in non-working order without prior notification will be the responsibility of the program participant. Wireless Matrix Proprietary and Confidential 16/16
