Test Bed for a Wireless Network on Small UAVs
White Paper Examples include multi-UAV swarming, flocking, and sensing operations; or, as a communication relay for a network of ground radios mounted at fixed sites, on vehicles, or in sensors. A key enabler is the ability of the... [01 Aug 2007]
Photos: Virtual war tests new technology
Photo The Combat Infrastructure Platform (CIP) and its Bowman digital radios (hence Bcip) were first accepted into military service in 2004. In a small field near Portsmouth, a war has been raging for the past couple of weeks. [14 Jun 2007]
Towards an Architecture for Efficient Spectrum Slicing
White Paper Most research in this domain is being conducted in design of cognitive radios and on specific PHY and MAC layer challenges associated with them. With the increased demands for wireless spectrum, dynamic spectrum sharing... [31 May 2007]
Peter Cochrane's Blog: Wi-fi radiation scare
Comment And yet strangely no one has spotted that domestic microwave ovens with faulty doors have a 1,000-fold greater density of radiation than wi-fi - or, even worse, the potential damage to thumbs and fingers that suffer radiation from car... [29 May 2007]
Fingertips of the Network: Featherweight Communicators and Sensors
White Paper The clipboards use IR to communicate with Pocket PC iPAQs carried by the staff and low-power 802.15.4 radios to communicate with a back-office data server. Hewlett-Packard has a business opportunity in low-power,... [16 Apr 2007]
An Efficient Implementation of NC-OFDM Transceivers for Cognitive Radios
