GoingWiMax.com was granted an interview with Berkeley Varitronics Systems CEO of 10 years, Scott Schober. BVS has provided design and consulting services for the wireless telecommunications industry for over 37 years. Most recently, BVS has introduced a line of WiMax and LTE testing tools and analysis software to meet the demand for network build out and optimization. In this interview, Mr. Schober offers his valuable knowledge and insight on a variety of current trends and topics in the wireless world today.
1) In light of WiMax trends in the past 3 years, in what way has your company been influenced and affected?
Berkeley Varitronics Systems (BVS) has seen significant WiMAX growth over the past three years greatly because of our diverse capability and smaller size. The initial business we appreciated was greenfield testing with our stimulus transmitter “Gator” and the “Coyote”, a modular receiver system. This combination allowed carriers such as Sprint and their respective partners to drive a particular area and plot out what type of coverage and signal propagation they would achieve in the 2.5 GHz 4G band planned for future deployment. This was done in all the major markets throughout the US with this system of test equipment. After the initial studies in 2007/2008 the carriers immediately could begin buildout of the actual network. BVS also provides the growing industry with the YellowFin 802.16e mobile WiMAX analyzer. The YellowFin allows 4G buildout to accurately reflect how WiMAX signals will propagate in real world conditions as opposed to using the traditional 3G propagation equipment and models of the past. Advanced measurements such as (Carrier to Interference Noise Ratio) CINR is measured along with Multipath information that could be problematic to the desired thru-put the carriers are looking to achieve. The fact that our portable test solution is used for in-building and out-door drive studies, coupled with our intuitive (Graphic Users Interface) GUI allows RF engineers around the globe to build out their 4G WiMAX networks rapidly with solid coverage.
2) To what degree do you think the introduction and increasing momentum of LTE will effect WiMax technology?
There are clear opportunities for BVS to grow as both WiMAX and LTE are embraced on a global scale. I continually hear of speculation as to whether WiMAX will survive and be replaced by LTE, but I believe the two competing standards will more likely migrate into an accepted standard that … Read the rest
