Wireless Mode

Description

The TR-24 has the ability to be booted in one of three modes. These modes are wireless, wired and master wireless. This section will discus the wireless mode.

The wireless mode is the most used mode of the beltpack. The wireless mode is set by holding the <TALK> button down as the unit boots. Then release it once a channel LED has lit indicating communication has started. In this mode the beltpack’s radio is active and the bottom RJ-45 Ethernet connection is deactivated. The beltpack communicates to other beltpacks wireless via a base station (This base station could be another beltpack if it was set to boot in master wireless mode.). The base station serves as a “relay” for audio packets going between beltpacks. One base station can serve up to ten beltpacks in full duplex mode (simultaneous talk and listen).

Ten Beltpacks in Wireless Mode

With ten beltpack in full duplex, up to 28 additional beltpacks can work off the base station if these beltpacks are in Push-to-TX mode. In Push-to-TX mode the beltpacks are listen only and the beltpacks’ channel lights are flashing until the <TALK> button is active. At that point the beltpack transmits full time and is in full duplex mode until user disables the <TALK> button again.

NOTE: Only ten full duplex beltpacks can work off a base station. Thus the number of full duplex beltpacks on that base must be reduce by the number of Push-to-TX beltpacks that could become full duplex if their users press the talk button.

For example, a base station has 6 full duplex beltpacks and 28 Push-to-TX beltpacks. Up to 4 of the 28 Push-to-TX beltpacks could go to full duplex at the same time without reaching system limitations. If 5 of the Push-to-TX were to become full duplex, for a total of 11 full duplex beltpacks, the system would go beyond its loading limit and all users will start to experience drop outs and delays in audio.

Multiple base stations can also be utilized in an installation. The base stations have the ability to communicate to each other via an Ethernet network connected to the RJ-45 jack on the rear panel. The connection between bases could be a direct connection via an Ethernet cable (100m, 328ft Max.) or connected via the building’s Ethernet infrastructure (See “Network Information” in the “Wired Mode” discussion for details.). Due to the base station’s wired interconnection, the beltpacks of the various base stations can communicate with each other.

Ten full duplex beltpacks is still the limit even if multiple base stations, connected via Ethernet, in non-overlapping RF coverage areas, are in a system.
