Following their long term efforts in promotion and application of most advanced technological solutions, in November 2006 MICRO-LINK d.o.o. engineers have performed extensive laboratory and field measurements of WiMAX (Worldwide Interoperability for Microwave Access) radio equipment using one of the first test samples of BTS Master (Base Transceiver Station – BTS) measurement instrument, manufactured by Anritsu Company, USA.
The instrument was made available to MICRO-LINK d.o.o. in order to perform test measurements of WiMAX certified networks and equipment, and also to obtain valuable field input data that would be useful in further development of the test system. During November 2006 MICRO-LINK d.o.o. engineers performed a series of detailed measurements on several types of WiMAX certified radio systems: RedMAX AN-100U base stations and SU-O subscriber terminals by Redline Communications Inc., PacketMAX 5000 base stations and PacketMAX 100 subscriber terminals by Aperto Networks Inc., MacroMAX base stations and ProST and EasyST subscriber terminals by Airspan Networks Inc. and BreezeMAX µBST base stations and BreezeMAX PRO subscriber terminals by Alvarion Ltd.
Detailed measurements have been performed in laboratory and on implemented live networks in trial or commercial operation. The scope of measurements included all radio parameters and parameters of WiMAX physical (PHY) layer. Measurements of interference and interoperability were also performed, as well as drive test measurements. The results of drive tests were correlated with GPS obtained coordinates in order to verify the radio signal propagation predictions.
