Company Background

For over 37 years, Berkeley Varitronics Systems has provided design and consulting services for the wireless telecommunications industry. Over the past 15 years, BVS has anticipated the wireless industry’s needs by developing more than 50 unique and portable field instruments for GSM, TDMA, CDMA and Wi-Fi site surveys. More recently, Berkeley has introduced a line of WiMAX and LTE testing tools and analysis software to meet the demand for network build out.

BVS is headquartered in Metuchen, NJ but has sales offices in the Northeastern, Southwestern and Southeastern regions in the United States as well as in Latin America and Switzerland. Internationally, BVS has wireless product distributors in over 40 countries spanning 6 continents for a true global presence.

Berkeley Varitronics’ WiMAX Products & Solutions

Handheld WiMAX Analyzers

The newly released YellowFin™ is a tablet PC analyzer for Mobile WiMAX spectrum analysis as well as packet measurements. Full spectrum analysis features include power triggers, peak hold / search, multiple waveform traces and markers. Packet analysis identifies RSSI, Cell ID and Segment data, multipath and CINR (carrier-to-interference-plus-noise-ratios) all on a preamble basis.

WiMAX Stimulus Transmitters

Tortoise™ is a dual-band, high power stimulus transmitter that contains an optional WiMAX modulator. Class A amplification, quad cooling fan system and lightweight (under 30 pounds) ensure that Tortoise will output the cleanest RF signal from a crane to a rooftop. The optional WiMAX OFDMA Modulator allows Tortoise to simulate WiMAX base stations and features adjustable step sizes, channel bandwidth and user settable Preamble number, Cell ID, Segment and frame lengths.

WiMAX Site Survey Software

DragNet™ PC software runs on a YellowFin™ receiver using a tablet PC for on-the-spot WiMAX site survey analysis. The internal GPS receiver provides geo-coded data for automatically time-stamped LAT and LON WiMAX measurements anywhere in the world. Survey data is then over-layed onto satellite viewed earth maps to provide a complete overview for coverage studies and network traffic analysis.

WiMAX Pre-Deployment

BVS has developed a pre-deployment test system specifically for WiMAX engineers and installers. The system is comprised of Class A stimulus transmitters (Gator™ or Tortoise™), high-speed, modular receivers (Coyote™ or Gazelle™) and drive-study mapping coverage software (Forecaster).

BVS Engineering

All Berkeley products are designed, built and tested at BVS headquarters in Metuchen, NJ. Our in-house approach allows for quick turnaround, first class technical support and custom engineering solutions that lead to the best wireless testing tools in the industry. BVS designs all of our own custom silicon for calibrated receivers such as the one used in our YellowFin WiMAX Analyzer. This handheld, high-speed 802.16e WiMAX Mobile receiver scans up to 40 samples per second measuring all 114 preambles. And since our design team developed the digital receiver, power system, DSP and GUI, we can provide a complete WiMAX solution to our customers including RF spectrum analysis, multipath, RF interference detection, direction finding and WiMAX packet demodulation on a preamble basis.

Berkeley manufacturing methods utilize automated surface mount (SMT) and through-hole printed circuit board assembly techniques that provide quick (sometimes in just 48 hours) delivery of prototype or small production runs. Because of our internal manufacturing experience, we are sensitive to costs, manufacturability, parts availability, test-ware and other critical elements. Hardware design and prototyping are expedited through the use of in-house CAD tools, including schematic capture, PC board layout, Bridgeport, mechanical and LSI gate array design and simulation.
