Move over 2G, Europe agrees to give 3G some space
News In May, the analyst group Analysys Mason said refarming 2G spectrum for 3G use would make it feasible to extend 3G coverage to rural areas, where rolling out more base stations may be seen by operators... [29 Jul 2009]
Peter Cochrane's Blog: Open info for all?
Comment It is a voluntary scheme under which mobile network operators make information available on the location and operating characteristics of individual base stations… Ofcom hosts the Sitefinder database on... [20 Jul 2009]
'Airwave does do data - unlike what some of the media say'
Comment It's also working on a second phase of its London Underground network rollout - to boost capacity at some major Tube stations and to fill in coverage blackspots in tunnels on overground parts of the Underground network. [11 Jun 2009]
Planning Base Station and Relay Station Locations in IEEE 802.16j Multi-Hop Relay Networks
White Paper In this paper, a problem formulation for determining optimal node location for Base Stations (BSs) and Relay Stations (RSs) in relay-based 802.16 networks is developed. The formulation... [23 Apr 2009]
Mobile WiMAX Femtocells: Big Challenges to Thinking Small
White Paper Mobile WiMAX femtocells may be beneficial in some deployments, especially in suburban or rural residential areas, where it might not be cost-effective for operators to deploy a dense network of macro base... [23 Apr 2009]
Multiple Antenna Systems in WiMAX
White Paper Multiple antenna systems are being implemented in both Airspan's Base Station and Subscriber / Mobile Stations. Increasingly the WiMAX technology will be integrated into portable devices such as laptops... [23 Apr 2009]
Bandwidth Allocation With Half-Duplex Stations in IEEE 802.16 Wireless Networks
White Paper That is to say, access to the medium by a number of Subscriber Stations (SSs) is centrally controlled by one Base Station (BS), which is responsible for allocating bandwidth to several MAC connections in... [23 Apr 2009]
Coverage Extension of WiMax Using Multihop in a Low User Density Environment
White Paper In this paper, a network consisting of BSs and fixed Subscriber Stations (SSs) is considered in which the SSs are capable to act as Relay Stations (RSs). The usage of multihop transmission enables a cost... [23 Apr 2009]
On the Construction of WiMAX Mesh Tree
White Paper In the mesh mode, Subscriber Stations (SSs) can directly communicate with each other, thus forming a tree, and can be used to forward other's data packets in a multihop fashion. On the contrary, in the PMP mode only one... [23 Apr 2009]

Rogue-Base Station Detection in WiMax/802.16 Wireless Access Networks
White Paper These reports can be assessed by the legitimate base stations, for instance, when a mobile station undertakes a handover towards another BS. This approach is based on the observation that inconsistencies... [22 Apr 2009]
Performance Analysis of Multiantenna WiMAX Systems Over Frequency-Selective Fading Channels
White Paper A multicell WiMax system which supports Orthogonal Frequency Division Multiplexing (OFDM) and antenna arrays at the base stations is considered in this paper as conforming to the IEEE 802.16-2004 standard. [22 Apr 2009]
Performance Evaluation of WiMAX System Using Convolutional Product Code (CPC)
White Paper The WIMAX technology based on air interface standard 802-16 wireless MAN is configured in the same way as a traditional cellular network with base stations using point to multipoint architecture to drive... [22 Apr 2009]
Local Authentication in WiMAX
White Paper Reliance on centralized base stations to perform node authentication creates a bottleneck that could be avoided completely through the addition of local authentication mechanisms. The IEEE 802.16... [22 Apr 2009]
Strategies for Fast Scanning and Handovers in WiMax/802.16
White Paper The paper propose strategies that a mobile station can use to reduce the time required for scanning operations while attempting to establish network connectivity or perform a handover between neighboring base... [22 Apr 2009]
