IDAS Systems An Overview of IDAS LINQVote and LINQVote+ A Overview prepared by Icom America Inc. Manufacturers of high-performance, award-winning radios for over 55 years.
IDAS LINQVote is a method of providing single group (at a time) enhanced area coverage via optimizing subscriber reception by the system. LINQVote systems typically have two or more receivers and one transmitter. IDAS LINQVote+ takes this concept further by providing multiple transmitters thus providing a much wider area of coverage than LINQVote. With Vote Scan, it also offers seamless coverage without requiring the subscriber equipment operator to change channels regardless of location. A typical LINQVote+ system has two or more receivers and at least two transmitters. Vote Scan in the subscriber equipment is optional with LINQVote+ but generally desired. Beaconing is also added to the system transmitters to optimize Vote Scan operation. With either LINQVote or LINQVote+, when initiating a call, the subscriber unit will uplink to a common RX frequency, shared by all the receive sites on the network. One or many of the sites may receive this transmission. These receive signals are transported, via the IP network as packets, to the Voting Comparator (which is just a standard FR5000 configured as a comparator unit). This unit determines the best received signal via the RSSI information contained in the LINQVote packets. With LINQVote+, the voted packets are also routed to addtional transmitters for multicast RF transmission. These multicast RF transmitters need to generally be on different frequencies (unlike the system receive). With LINQVote, the subscriber is always listening to the main transmitter and the range of the system will be limited by the range of the main system transmitter. 2 IDAS LINQVote, LINQVote+: Overview
A simple LINQVOTE system FR5000 Stable, flexible and high-performing IDAS repeater for Multi-site Conventional systems, and MultiTrunk systems. In the case of LINQVote+ with multiple transmitters, Vote Scan is activated on the subscriber unit in addition to beaconing on the system side of things. Functionally, the Vote Scan and beaconing systems work together. Periodically, the site transmitters generate a beacon pulse. These pulses are received by the subscriber units and are analyzed for the strongest RSSI. The subscriber unit then listens for traffic from the site with the strongest beacon pulse. Thus the subscriber radio is always monitoring the strongest available site for traffic. Because the subscriber units are always monitoring the transmitter beacons, they will automatically change to the strongest site. No channel changing is required by the user. You can still have LINQVote+ without subscriber vote scan and beaconing. But in that case, the subscriber will have to change channels manually as they roam throughout the operational area of the system. 3 IDAS LINQVote, LINQVote+: Overview
