Multipoint-to-multipoint in DSSS mode. |
| Repeaters |
Modem can be configured as repeater to extend range and coverage in DSSS mode. |
| Packet structure |
Data is grouped into packets for radio transmission. |
| Addressing |
255 unique addresses, 1 broadcast address, multicasting possible. |
| Security |
Unique password to prevent eavesdropping and unauthorized transmission in DSSS mode. |
