Assessment of cellular planning methods for GSM
نویسندگان
چکیده
The performance of various cellular planning methods for GSM, which decrease co-channel interference without sacrificing traffic capacity, is evaluated. For measuring the advantages of each method, the Carrier-to-Interference Ratio, is calculated. The use of different clusters and the benefits of sectorisation in C/I are studied. An evaluation of the influence of Frequency Hopping on C/I is also done. The Multiple Re-use Patterns (MRP) method is investigated as well, and a comparison is performed with previous results. The results show that changing the size from 4 to 3 leads to a decrease in C/I of 2.6 dB. Several real antennas are studied for sectorisation, the best results being obtained for the 90o beamwidth one. The use of sectorisation, together with MRP, allows an increase in network performance, without visible additional costs.

A TESLA-based mutual authentication protocol for GSM networks
The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...
متن کاملFrequency Planning in GSM Networks: Models, Heuristics, and Lower Bounds
Frequency planning is a key issues in fully exploiting the radio spectrum available to GSM . It has a significant impact on the quantity as well as on the quality of the radio communication services. Every change of the radio network infrastructure typically calls for a change of the frequency assignment. Roughly speaking, radio communication requires a radio signal of sufficient strength which...

Background & Aims: Since previous studies on complications resulting from exposure to electromagnetic fields emitted by mobile phones are based only on self- reported symptoms, this study was performed to find the capability of users in recognition of real/ sham microwave exposure and probable alterations of vital signs after microwave exposure. Methods: In a two- step screening, from 700 stude...
