MICOM-2E-ALE Owner’s Manual LQA Memory The ALE builds a database of connectivity information based on calls and digital ALE “sounding” messages transmitted by other stations in the network. This information is stored in a special “LQA memory” and used to determine the link quality of all channels in the networks. The data in LQA memory is “time-weighted”, that is, recent information is given more value than old, thus compensating for changing propagation conditions.
Automatic Link Establishment (ALE) To select the best sounding cycle time, the trade-offs must be considered. On the one hand, a shorter cycle ensures a more updated LQA memory; thus the channel with the highest LQA value will, in fact, have the best link quality at that point in time. On the other hand, a shorter sounding cycle increases network occupancy due to more frequent sounding messages, leaving less channel-free time for the users.
MICOM-2E-ALE Owner’s Manual occupancy. A 60-minute cycle would result in 40% occupancy. A 90minute cycle would result in 27% occupancy. A 120-minute cycle would result in 20% occupancy. It can now be decided which sounding cycle is the best for any particular network, taking into account the trade-offs described above.
Automatic Link Establishment (ALE) Bi-directional Handshake The bi-directional handshake is a shorcut procedure to exchange LQA scores with other stations in the system without establishing a link. This procedure is useful in the following cases: • The radio has only recently been switched on and an automatic • sounding cycle has not been completed yet. The operator wishes to update the LQA scores before initiating a call to another station. When a new or passive station joins to the system.
