Evaluation of two wireless communication standards for public safety and security (PSS) networks.

摘要

Law enforcement agencies in many countries have been using analogue wireless transmission networks based on an international standard known as MPT-1327 to support their operation. Recently, there is a significant move towards digital communication standards, such as Terrestrial Trunked Radio (TETRA) and TETRA Police (TETRAPOL). In this thesis, a study was conducted to compare the performance of these two standards when employed in a realistic network environment.; Selection of a realistic network environment was based on two criteria, namely the availability of data and the presence of a topology that represents urban and suburban settings. The City of Abu Dhabi, U.A.E. met these two criteria and was selected for this study. The methodology applied, however, is quite general and can be applied to typical environments in which law enforcement agencies wish to deploy Public Safety and Security (PSS) networks.; Both TETRA and TETRAPOL standards were evaluated by comparing their area coverage requirements and traffic capacity. The TETRAPOL standard was found to provide better coverage for the same number of base stations while the TETRA standard was found to provide a slight capacity cost advantage.
