SUs can be placed only in WORP Satellite mode. The Wireless Outdoor Router Protocol (WORP) is a polling algorithm

designed for wireless outdoor networks. WORP takes care of the performance degradation incurred by the so-called

“hidden-node” problem, which can occur when wireless LAN technology is used for outdoor building-to-building

connectivity. In this situation, when multiple radios send an RTS, if another radio is transmitting, it corrupts all data being

sent, degrading overall performance. The WORP polling algorithm ensures that these collisions cannot occur, which

increases the performance of the overall network significantly.

WORP dynamically adapts to the number of SUs that are active on the network and the amount of data they have

queued to send.

Subscriber Unit Wireless Interface

The following parameters are configurable:

• Interface Type: The interface type can only be WORP Satellite.

• Base Station System Name (SU only): The name found on the system page of the BSU to which this SU is

connecting. This parameter can be used as an added security measure, and when there are multiple BSUs in the

network and you want an SU to register with only one when it may actually have adequate signal strength for either.

The System Name field is limited to a length of 32 bytes.

If the Base Station System Name is left blank on the SU, it can register with any BSU with a matching Network

Name and Network Secret.

• 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.
