LigoWave’s iPoll PtMP (Point to Multi-Point) proprietary protocol is an innovative solution to eliminate transmission congestion and close cluster interference created in PtMP wireless installations. To see how Triple Play comes into use we’ll first need to provide you with a bit of information on the LigoWave QoS.

More about the QoS

iPoll is equipped with a traffic prioritization technique, which is mandatory in multiple services networks. QoS is implemented on four wireless transmit queues, where each queue has a different priority from lowest to highest. The prioritization policy uses the WRR (Weighted Round Robin) algorithm, which means that bigger capacity is given to high queues and smaller to lower queues. If the radio performance degrades the lowest priority traffic will be dropped first.

The base station performs traffic identification and mapping for the queues. The traffic has to be marked before passing the radio. The marking should be done on the equipment before the base station and after the CPE. The data can be marked according to VLAN 802.1p and IP ToS/DSCP fields. VLAN has precedence over IP (in a case when two marks mismatch). For more information refer to the user manual or contact customer support.

This is where Triple Play comes in.

The proprietary wireless protocol, QoS mechanism, and advanced multicast handling support Triple Play services in LigoDLB wireless networks.

Standard Triple Play is Voice (VoIP), Video (IPTV) and regular data to the consumer. VoIP is transferred in both directions at the higher priority queue. IPTV goes in multicast towards the customer from the network. The base station performs multicast switching and prioritizes the data. The balance of the radio capacity is assigned to the Internet data and arrives as best-efforts traffic.
