Note: NOTE 1 to Table 1: Occupational/controlled limits apply in situations in which persons are exposed as
a consequence of their employment provided those persons are fully aware of the potential for exposure and
can exercise control over their exposure.
Limits for occupational/controlled exposure also apply in situations when an individual is transient through a
location where occupational/controlled limits apply provided he or she is made aware of the potential for
exposure
Note: NOTE 2 to Table 1: General population/uncontrolled exposures apply in situations in which the
general public may be exposed, or in which persons that are exposed as a consequence of their employment
may not be fully aware of the potential for exposure or cannot exercise control over their exposure.
Declaration of Conformity Compliance Information
Class B computer peripheral
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Note: Modification of this device may void the user’s authority to operate the equipment.

Welcome
This guide describes how to install and use the Expedience mobile subscriber unit (MSU).
The MSU maintains contact with base stations in order to provide wireless high-speed
Internet access to subscribers in moving vehicles, such as cars, trucks, and vans.
This guide is intended for use by professional equipment installers. Service providers should
not attempt to install the MSU.
Installation overview
This section provides an overview of the tasks you will perform when installing the MSU.
To install the MSU:
1Determine where the MSU will be mounted inside the vehicle.
2Install the antenna in the desired location.
3Run the antenna cable to where the MSU is mounted and plug the cable into the MSU.
4Determine the appropriate length for the MSU power cable.
a If using the full length of the cable, go to step 5.
b If you want to change the location of the fuse holder, cut the cable and use the crimps
to insert fuse holder at the desired location on the power cable.
5Power the MSU by preparing the cable and attaching the MSU power cable to the battery
or to an unused, positive fuse block terminal.
6Ground the MSU to a screw that goes to chassis ground.
7Connect the MSU cable harness to the connector on the back of the MSU.
8Connect the MSU to the laptop computer using the RJ-45 cable.
For further information about these tasks, refer to the sections that follow.
Determining where to install the MSU
The MSU is installed inside the vehicle. Cables on a cable harness connect the MSU to a
power source, to the frame of the vehicle for grounding, and to the subscriber’s laptop
computer. Also, a separate antenna cable connects the antenna to the TNC antenna
connector on the MSU.
When choosing a location for the MSU in the vehicle, be sure the antenna cable and the cable
harness can reach the MSU.
2Installing the mobile subscriber unit
Cabling overview
Figure 1 illustrates how the antenna connects to the MSU. It also shows how the cables
connect the MSU to a power source, to the vehicle’s frame for grounding, and to the
subscriber’s computer.

Installing the MSU inside the automobile
The back of the MSU is a mounting plate with 4 holes. The MSU can be mounted on an
equipment shelf in the vehicle or on the side of the automobile.
The mounting holes on the back of the MSU are vertically spaced 9 x 5/8 inches apart center
to center. The horizontal holes are spaced 3 x 1/2 inches apart.
Figure 2 shows the back of the MSU.

4Installing the mobile subscriber unit
Installing the antenna
You should only use the antenna that NextNet has approved for use with the MSU.
The antenna is installed on a horizontal surface on the exterior of the vehicle, usually on the
trunk or on a roof. To secure the antenna to the vehicle, you can use one of the following
mounting options:
• You can use a magnetic mount to secure the antenna to the vehicle.
• You can use a regular mount, which requires you to drill or use an existing hole through
the exterior of the vehicle.
After you install the antenna, run the antenna cable and connector to where the MSU is
installed.
Antenna requirements
This section explains which antennas can be used with the MSU.
Note: The antenna used with the MSU depends on the Effective Isotropic Radiated Power
(EIRP) requirements of the particular country in which the MSU is operated.
In the United States, the antennas approved for use with an MSU operating at 2.6 GHz are:
• The BMMG2400ML195C antenna from Maxrad, which is magnetically mounted to the
vehicle
• The IMAGO-2600 antenna from Mobilemark, which is magnetically mounted to the
vehicle.
