Radio/Air Interface Features
Network Role
The Network Role can be one of the following:
• Access Point (AP); initiates contact/communication with End Point/Repeating End Point. The
Access Point is the radio that is normally connected to the Enterprise or backhaul system where
access to the radio system occurs. Downstream radios such as End Point’s and Repeating End
Points connect to the Access Point.
•
End Point (EP); waits for an Access Point radio to initiate communication. The End Point is the
radio that is connected to the end devices in the field.
•
Repeating End Point (REP); waits for an Access Point radio to initiate communication.
Point to Point (PTP)
A PTP network consists of two radios; Access Point (AP) and End Point (EP) that can only
communicate with each other. The Access Point sends a beacon message to the End Point, which then
responds.
Data may be transferred in either direction. Data transfer speeds can be manipulated using the Max
Payload Bytes and Dynamic Payload settings. When set to PTP with multiple End Point Transmit Rates
selected, both radios will be fixed to the highest End Point Transmit Rate. The Access Point Transmit
Rate will also be fixed to the same speed/modulation. Refer to the How to set up an ISM PTP Link
section for configuration information.
Point to Multi-Point (PMP)
A Point to Multi-Point network consists of one Access Point and many End Points. The Access Point
sends a beacon message to the End Points, which then respond.
