RSS mobile signalGoogle's vision for an open wireless world
News But he might use AT&T while at work, where the signal is stronger. When people buy mobile phones today, they're essentially locked to one provider. Earlier this week, the search giant filed a patent... [29 Sep 2008]
Europe-wide wireless broadband on the way
News The move echoes calls by European commissioner for information society and media, Viviane Reding, earlier this year for the UHF spectrum to be allocated for WiMax mobile broadband use once the analogue... [24 Sep 2008]
Photos: Tomorrow's tech showcased by inventors
Photo Touching the piezoelectric textile pad lowers its electrical resistance causing a current to flow through the aluminium wires and sending the signal to the attached device. The system, seen here, works by sending an... [18 Sep 2008]
Five reasons I don't miss my 3G iPhone
Comment Even when there apparently was a signal it would often simply not work - or else be so slow as to make browsing painful. Yes it's certainly best in class for surfing the mobile web - but only when it works. [10 Sep 2008]
The flexcell Platform: A Software-Defined Radio Architecture for the Next Generation of Wireless Hubs and Open Architecture Wireless Hubs
White Paper The RF board receives the wideband analog RF signal from one of the antennas, converts the signal through analog circuits to a wideband analog IF signal, and then converts the... [02 Sep 2008]
Peter Cochrane's Blog: Out of range?
Comment Oh, and if you are having trouble getting a good mobile phone signal - standing in front of a dish also helps but it isn't very portable. Unfortunately, the location was at a marina some 500 metres from... [15 Jul 2008]
RF Bandwidth Capacity and SCM in a Radio-Over-Fibre Link Employing Optical Frequency Multiplication
White Paper As a result, the infrastructure costs rise enormously in in-building and business environments, where many micro- and picocells with even line-of-sight coverage and high signal processing load have to be deployed. [11 Jul 2008]
Efficient High-Frequency Bandwidth Extension of Music and Speech
White Paper However, at very high compression rates the perceptual quality of the signal is degraded, which is mainly exhibited as a loss of high frequencies. This paper proposes an efficient algorithm for extending the bandwidth of... [11 Jul 2008]
Robotics-Based Location Sensing Using Wireless Ethernet
White Paper This paper describes the design, implementation and analysis of a system for determining position inside a building from measured RF signal strengths of packets on an IEEE 802.11b wireless Ethernet net-work. [10 Jul 2008]
An Experimental Study of Localization Using Wireless Ethernet
White Paper Wi-Fi-based localization relies on the existence of one or more Wi-Fi devices in the environment to act as beacons, and uses signal strength information from those beacons to localize the robot. This paper studies the... [10 Jul 2008]
Simulative Performance Optimization for TCP Over UMTS
White Paper Generally, wireless networks have many different characteristics compared to fixed networks, as the radio signal is affected by fading, shadowing and interference that also change over time. Most of the future... [03 Jul 2008]
Linear Quadratic Power Control of CDMA Cellular Systems
White Paper The role of power control is to command the mobile station to transmit at the lowest power possible while maintaining the desired signal quality and thereby minimizing the total interference and... [03 Jul 2008]
Microsoft embraces cloud computing with 'Live Mesh'
News Industry analysts said the product may signal a watershed moment within Microsoft to embrace a technology that the company viewed as a threat in the past. Microsoft's "Live Mesh" program, which uses the internet as a... [23 Apr 2008]
Successive Interference Cancellation Algorithms for Downlink W-CDMA Communications
White Paper In this paper, successive intracell interference cancellation (IIC) of the wideband-code division multiple access (W-CDMA) signal at the mobile unit is considered. Three new interference cancellation... [10 Apr 2008]
OFDM for Mobile Data Communications
White Paper Only recently has it been finding its way into commercial communications systems, as Moore’s Law has driven down the cost of the signal processing that is needed to implement OFDM based systems. This paper describes... [10 Apr 2008]
