There are different communication standards in present mobile communication industry. Each of this standards has its own feature, architecture, and channel assignment strategies. Each mobile operator uses one of any standard and their aim is to support as much user as possible to communicate with tolerable interference. For that reason they use different cluster size and frequency planning to cover entire geographical area. To reuse the given bandwidth within the entire geographical area some cells uses same sets of frequency and interference arise when the distance between these cells is small. Also when distance is large then capacity is going low. In this thesis our work is to investigation the co channel interference among different cluster size assuming a limited sub urban geographical area in a cellular GSM network. Also we calculate the number of users using each of this cluster size and finally design a cellular system in this geographical area using best results (minimum interference and maximum capacity).

Localization Systems

Localization systems for indoor areas have recently been suggested that make use of existing wireless local areanetwork (WLAN) infrastructure and location fingerprinting approach. However, most existing research work ignores channel interference between wireless infrastructures and this could affect accurate and precise positioning. A better understanding of the properties of channel interference could assist in improving the positioning accuracy while saving significant amounts of resources in the location-aware infrastructure. This paper investigates to what extent the positioning accuracy is affected by channel interference between access points. Two sets of experiments compare how the positioning accuracy is affected in three different channel assignment schemes: ad-hoc, sequential, and orthogonal data is analyzed to understand what features ofchannel interference affect positioning accuracy. The results show that choosing an appropriate channel assignment scheme could make localization 10% more accurate and reduces the number of access points that are required by 15%. The experimental analysis also indicates that the channel interference usually obeys a right-skewed distribution and positioning accuracy is heavily dependent on channel interference between access points (APs).

Mobile Communication Industry

With the improvements in communication technologies and the increased need for mobile communication among users, the mobile communication industry has been faced with fast-paced developments in the last few decades. The developments in mobile communication technologies provide opportunities that cannot be provided by traditional communication tools. Mobile applications are considered examples of such opportunities. The services offered by mobile phone technologies are diversified by the mobile applications that can be downloaded through digital platforms, and with these applications smart-phone users become even more active users. The current chapter reports findings from a study that employed a structured online questionnaire with 271 smart-phone users. The findings revealed that mobile application use, either free or paid, is explained by the period of smart-phone use, attitudes toward mobile applications, financial cost, and opinion leadership. Furthermore, free applications are more frequently used when the innovativeness increases and the perceived application cost decreases. The results present important outcomes for mobile companies, the digital platform providers, as well as mobile application producers.
