Operating Mode
Four operating modes are available on the R2 Extender. In a point to point environment where there
are only two radios, Peer-to-Peer is recommended as it works more efficiently.
Base Station: The R2 Extender connects directly to the main Ethernet LAN and receives
connectivity from other wireless devices.
CPE: The R2 Extender connects to a remote LAN and the Base Station in it.
Peer-to-Peer (CSMA)
: The R2 Extender connects to another wireless device within the same
networking program using CSMA protocol. CSMA ensures that only one node is transmitting on the
network at any one time. Under this mode, both PTP and PTMP are available. It is highly
recommended to use this mode when the distance between two nodes is less than 20KM.
Peer-to-Peer (TDMA)
: The R2 Extender connects to another wireless device within the same
networking program using TDMA protocol. TDMA divides each cellular channel into multiple time
slots to increase the amount of data that can be carried, hence increase the throughput. Under this
mode, only PTP is available and is suggested to use when the distance between the two R2
Extenders is greater than 20KM. To make the P2P TDMA work, you need to set the same Group ID
on both 2 peers.
