A Novel Wireless Local Positioning System Via a Merger of DS-CDMA and Beamforming: Probability-of-Detection Performance Analysis Under Array Perturbations
This paper investigates the Probability-Of-Detection (POD) performance of a novel Wireless Local Positioning System (WLPS) realized via Direct Sequence Code Division Multiple Access (DS-CDMA) and beamforming techniques. The proposed WLPS has unique signaling schemes that discriminate it from the traditional wireless systems and allows the WLPS to have many civilian and military applications. The WLPS consists of two main parts: the detecting unit, a base station carried by a mobile unit defined as Dynamic Base Station (DBS), and the being detected unit, a TRansponder (TRX) that is mounted on the targets, each assigned a unique IDentification code (ID code).

Delivering Voice and Data: Comparing CDMA2000 and GSM/GPRS/EDGE/UMTS
Regardless of the wireless technology used, the same rule applies: The more subscribers, minutes and megabytes that a cell site can handle, the lower the operator’s cost to deliver those services. Lower overhead costs in turn determine the operator’s ability to price voice and data services competitively and still turn a profit. This white paper uses simulations to discuss how the evolution of the CDMA2000 and GSM families of technologies will affect their voice and data performance, including their spectral efficiency when delivering those services. While different technologies have distinct evolution strategies and different constraints, voice and data capacity will significantly improve with technology advancements in the coming years.

Ambulance crew learns to be skeptical of GPS
Don’t just blindly follow what the GPS receiver tells you to do! Instead of driving eight miles northeast of London to Brentwood, the ambulance drove 200 miles northwest to the suburbs of Manchester before the drivers realized their blunder and turned around, The Times of London reports. The total trip took more than eight hours. The crew, which reportedly has become a laughing stock, “was relatively new to the job,” a spokesman for the London Ambulance Service said. “Obviously they thought they were going to a hospital further afield.” How does the ambulance service plan to prevent this kind of thing happening in the future? Drivers have been told to study their geography and learn to think for themselves. UPI.com
