Elektrobit (EB) has released a whitepaper on Cognitive Communication Networks that explores how cognitive radio can be utilized in military communications. The white paper discusses how cognitive radio works and how future wireless systems equipped with cognitive radio capabilities could dynamically access new frequency bands, and at the same time protect higher-priority users on the same bands from harmful interference. Cognitive radio capabilities utilized in military communications would enable mobile troops to communicate and share information even more effectively.
The Centre for Wireless Communications (CWC), a project-funded research group operating in conjunction with the Department of Communications Engineering at the University of Oulu, Finland, is employing EB Propsim F8 radio channel emulator and EB MIMO OTA Application to provide wireless testing and research capabilities under the most realistic propagation conditions.
This paper describes how LTE products, systems and applications are tested in a realistic wireless environment – not in the field but in a laboratory. The benefits of beyond conformance testing compared to standard conformance testing are explained. LTE terminal and base station manufacturers as well as operators are recommended to go beyond basic testing and carry out performance measurements already in the early phases of LTE product development. The White Paper also discusses the different testing methods and introduces key radio channel models which can be used in the testing process.
Product Feature A Hardware Multichannel Simulator for Wideband Wireless Systems Elektrobit Kauniainen, Finland Hardware-based multipath fading simulators have traditionally been used to generate up to two simultaneous fading channels. Mobile network testing and future wireless applications like geolocation, smart antennas and multiple input multiple output (MIMO) systems, however, require...
