Advanced Wireless Communication Techniques

Measurement and optimization of the quality, coverage and capacity of a wireless network system is one of the mandate conditions for today’s mobile technology. For that, numerous radio frequency (RF) drive test tools are used for wireless technologies like global system for mobile communication (GSM), code division multiple access (CDMA), global package radio services (GPRS), third generation (3G), evolution data optimized (EVDO), etc. In this work, two such tools like telecom expense management software (TEMS) and X-CAL are used to collect reasonable data accurately in real time for two different mobile networks like GSM and long-term evolution (LTE). Basically, the drive testing technique is nothing but an automobile that carries a wireless network system making set up for drive test and at the same time RF engineers keep records of various parameters (physical and virtual) of mobile cellular service for report making for a particular geographical area. The drive testing technique is categorized into three broad headings as: network benchmarking, optimization and troubleshooting and finally service quality monitoring. The objective of these types of drive tests is to collect datasets like signal level, signal quality, dropped calls, blocked calls, call statistics, Global Position System (GPS) location co-ordinates, etc. In this process, drive testing files are used to diagnose the root sources of dropped calls or omitted neighbour cell assignments due to specific disputes, typically confined disputes or network disputes. Objective of drive test and electromagnetic field wave (EMF) survey is to optimize RF in the mobile wireless network. In this process, one network can optimize its throughput power by using less spectrum by proper regulation work of RF engineer.
