► The network makes the automatic selection of accessing terminals and will broadcast the signal on the same frequency throughout the coverage area ► Communications can be both on open and on selective channels, with semi-duplex mode between mobile terminals or duplex mode between Repeaters ► Using the same RF channel over the whole coverage to give a “large single cell” ► No complex setup required, Kairos automatically manages the complex configuration and timing needed for any size of simulcast system making setup much easier ► Additional sites can be added without a requirement forĭMR Tier 2 simulcast offers increased range while DMR Tier 3 offers large capacity wide area ► Easily expanded without reprogramming radios ► Reduced co-channel interference from multiple sites ► Low number of talk-paths required at each site Radios connected to a Simulcast network can move from one location to another without the need for the user to change channels simulcast is extremely user-friendly. In Multi-Frequency (multi-site) systems, where different frequencies are required at each radio site, the handover (site coverage changing) and roaming (research of desired group of users) is relatively slow and users will typically have to change channels or use a beacon function as they move between sites.Ī Simulcast network allows all repeaters synchronise their transmissions in time, effectively creating a large single cell which significantly reduces the time required for transmissions to reach a radio terminal or to locate the correct base station.
