Aeroflex 3900 radio test set offers new TETRA energy economy mode option for testing battery-life of portable mobile radios WICHITA, KS—August 23, 2006 —Aeroflex is announcing the availability of its new TETRA Energy Economy Mode (EEM) option for the popular Aeroflex 3900 series analog and digital radio test sets. The new TETRA EEM option enables more flexible battery-life testing for developers, operators and users of TETRA hand held mobile radios who need to prove their design and quantify or qualify battery-life performance claims. The new option will enable Aeroflex 3900 series users to configure battery test scenarios that simulate particular operational conditions. Additionally, it will provide the testing flexibility to characterize the expected battery life performance when the device is in use on the network. “Aeroflex developed this new option for testing TETRA battery life in response to a number of requests from key mobile manufacturers,” said Graham Stevens, product manager, Aeroflex. “Aeroflex continues to lead the market in developing testing capabilities that support the evolving and emerging technologies being used in the professional mobile radio market, particularly in the areas of TETRA protocol and TETRA conformance test.” About the TETRA energy economy mode Even in idle mode, a TETRA mobile station must monitor the infrastructure to detect signaling information–such as a new incoming call–transmitted by the base station. This constant monitoring by the mobile radio uses energy and degrades the battery life, even though messages to the handset may occur infrequently. The EEM procedure is a method of conserving energy while in idle mode. 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. By testing the energy economy mode, one can determine if the protocol has been implemented properly and also test the effect the economy mode has on power consumption and battery life. The 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 will temporarily suspend its sleeping cycle until it sends its last signaling message. Therefore, the more signaling messages it receives, the more times its sleep is interrupted. The TETRA EEM option provides protocol signaling to control a mobile radio’s energy economy mode from active mode through energy groups EG1 (shortest sleep) to EG7 (longest sleep) and is used in conjunction with the comprehensive signaling capabilities already within Aeroflex’s TETRA mobile station option. Availability and Requirements The TETRA EEM Option (Option 114) is available to order now 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.
