Field Descriptions
Interface Type
The interface type can be WORP Satellite or WORP Base.
Network Name
A Network Name is a name given to a network so that multiple networks can reuse the same frequency
without problems. An SU can only register to its base if it has the same Network Name. The Network Name
is one of the parameters that allow a Subscriber Unit to register on a Base Station. The Base Station
System Name and Frequency Channel also are parameters to guide the SU to the proper BSU on the
network, but they provide no security. Basic security is provided through encryption, as it causes none of the
messages to be sent in the clear. Further security is provided by mutual authentication of the BSU and SU
using the Network Secret. The Network Name can be 2 to 32 characters in length.
Operational Mode (not configurable)
This field indicates the operational mode of the unit – 11a, 11b, or 11g – depending upon the specific
Tsunami MP.11. This operational mode cannot be changed as it is based upon a license file. For the
5054-R, this field shows 11a; for the 2454-R, this field shows 11g.
Dynamic Data Rate Selection (DDRS) Status
The WORP Dynamic Data Rate Selection (DDRS) lets the BSU and SUs monitor the remote average
signal-to-noise ratio (SNR) and to adjust the data rate to an optimal value (to provide best possible
throughput) according to the current communication conditions during run-time.
Each frame received in the WORP protocol reports the signal and noise level in dBm at which the sender
received the previous frame from the receiver, and provides the values to calculate the signal to noise ratio
(SNR) in dB. SNR is calculated then averaged:
