3.1 General Description
The Radio Port (RP) is the radio equipment base station that relays the
communication from the user side to the operator/network side or vice versa. A
standard installation for RP applications places several RPs in a common service
area. However, the number of RPs and their distribution deployment depend on
the following factors:
• Topography of the service area
• Subscriber distribution in the service area
• Desired Grade of Service and traffic load.
There are two types of RPs:
• Outdoor - is small in size and is encased in a weather-proof cabinet. This
gives it the potential for various mounting scenarios - installed on the
dedicated poles, buildings, or street lamp poles.
• Indoor - is also small in size and can be installed in public and semi-public
locations like an office building, a shopping mall, or an underground
parking lot.
The power for the RP is fed from the RPC and a synchronous clock is delivered
from the RPC. The radio link between the RP and the FSU, or the RP and the PS
is based on RCR-STD 28 Ver.2 PHS technology, which defines frequency bands,
protocol, and so on. Both the indoor and the outdoor RPs have a 2 branch built-in
antenna.
The architecture of the WLL system is illustrated in Figure 3-1, which is followed
by a block diagram of the RP.
