Infrastructure overview
The base station and AP server are network infrastructure components supplied by NextNet
Wireless. The network access provider configures and maintains this equipment.
Additional infrastructure components include switches for use at the base station cell sites,
and the head-end switch. These switches are supplied by the network access provider. If
desired, the network access provider can purchase the switches through NextNet Wireless.
Base station overview
The base station maintains contact with CPEs at your subscribers’ sites. The base station
integrates the transceiver and modem into one device.
Under typical configurations, the base station covers an approximate radius of 2 to 3 miles,
with a 5 mile maximum. If desired, network access providers can configure their base stations
to cover a maximum radius of 20 miles. To cover up to 20 miles, the network access provider
enables the extended range feature.
There are two types of base stations offered by NextNet Wireless:
• An indoor-only base station that slides into a base station cabinet after the cabinet has
been installed on a standard 19 inch rack. This base station is known as the rackmount
base station (RMB).
• A base station that can be installed indoors or outdoors. This base station can be installed
on a tower, on a roof, on a wall, or on a rack. This base station is known as the base
transceiver station (BTS).
Figure 1.1 shows an individual RMB which will be installed inside a cabinet. This cabinet is
then installed on a standard 19 inch rack. Up to 8 RMBs can be installed inside a cabinet.
