Wireless networks, smart phone technology and technologies like the Global Positioning System (GPS) and traditional cellular network such as Global System for Mobile Communications (GSM) and other radio frequency medium have opened up new opportunities in implementing secure monitoring system and is also emerging as a ubiquitous tool for securing Bank Lockers and Cars. The current scenario concentrates on implementing a system that enforces banking security by restricting any possibilities of unauthorized access. Theft in banks has been frequently reported by breaching the existing security. There is need to improve and fine tune bank security plans by using GSM technology, smart phone technology and microcontrollers devices. The current security plan has extra safety and alarming features that ensure the system more secure than ever.
SDMA techniques involves spatial dimensions, medium access control, space time scheduling, random accessing and performace evaluation too. There are various protocola as well, for the better working of the system architecture.
