Mobile network settings influence on vehicle remote control equipment power consumption

3G cellular data networks in Lithuania are growing very rapidly despite appearing new network technologies in the market. As when writing this paper, 262k users were using UMTS high speed data transfers in Q3 2010 and this is 24.4% more than in Q2 [1]. All mobile network providers in Lithuania can offer high data transfer rates for various user needs and their used applications. For the quality of service measurements, Communications Regulatory Authority uses just HTTP data transmission (receipt) speed rate values in the operators' UMTS (3G) networks (as CRA stated in annual report for the year 2009). But speed is not everything as many consumers in the industry are experiencing recently. In addition, improvements now also revolve about reducing the signalling load incurred [6] when a radio bearer is established, modified or released. Another area for improvements is the signalling overhead on the air interface when little data is transferred as it consumes resources and causes battery drain from the mobile phone's point of view [7], Battery lifetime is a big challenge with smart phones. In this paper, we focus on the UMTS (the Universal Mobile Telecommunications System) 3G network, which is among the most popular 3G mobile communication technologies.
