The TETRA Energy Economy Mode (EEM) option for the Aeroflex 3900 series analog and digital radio test sets enables more flexible battery-life testing.
Developers, operators and users of TETRA hand-held mobile radios can now configure battery test scenarios that simulate particular operational conditions. The can also characterize expected battery life performance when the device is in use on the network.
Before EEM, constantly monitoring the infrastructure energy degraded battery life, even though messages to the handset may occur infrequently. EEM works by assigning the mobile radio to an energy economy group, which tells it how long it can "go to sleep" between times it must monitor the messages from the base station.
Testing parameters include the energy economy group and the quantity of signaling activity. For instance, anything that causes the mobile station to temporarily suspend the sleeping cycles.
Whenever the TETRA mobile station receives a signaling message, it temporarily suspends its sleeping cycle until it sends its last signaling message. .
The TETRA EEM Option (Option 114) is available to order now starting at U.S. $1,000 and can also be retrofitted in the field. The Aeroflex 3901 and 3902 require software version 1.5 or above and must also have TETRA Mobile Station Option (Option 110) licensed and enabled. The Aeroflex 3901 and 3902 are available for order starting at U.S. $27,950.00.
