COMPONENTS
Command Server
The MBS2-LP command server is a logical entity that contains information about routing, MBS2-
LP status, and configuration parameters.
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 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 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.
802.11b 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, up to 150 feet.
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 modem card capable of communicating with the Wireless Tether modem and approved
by Wireless Matrix.
