Description

Press Releases March 2008 Praxsym is pleased to announce the addition of coverage for Broadband Radio Service (BRS) bands in its PST family of test transmitters. Commonly referred to as WiMAX in the United States, the BRS configuration covers the 2495-2690MHz bands. The PST is complete, portable CW test source. The output has a maximum of +33dBm (2W), adjustable down to +10dBm in 0.1dB steps. December 2007 Praxsym, Incorporated announces the expansion of its PST dual band test transmitter product. 600MHz/1400MHz WMTS, 1700MHz/2100MHz AWS, 2500MHz BRS (WiMAX) and 700/800MHz Public Safety were added to the base group of 805-960MHz, 1850-1990MHz and 1710-1880MHz. Extending the utility of the product further, power output levels of +10 to +33dBm (2W) and 0 to -70dBm are now part of the lineup. November 2007 Praxsym, Incorporated provides engineering and hardware support for underbuilding licensed 6GHz microwave point-to-point network. Using the existing waveguide and antennas, PTP system owners may add significant digital capacity at the cost savings unlicensed 5.8GHz equipment affords. Praxsym works with the legacy system administrators, tailoring hardware kits to meet individual needs. Bandpass filters and circulators are included as well as most other peripheral items for completing the installation. Customer Comments on our t-meter "Just a quick note on your meter. We are in the midst of building a pretty large network - spans several hundred miles, several very tall, tricky towers. We bench tested all our radios prior to deployment using your meter. The meter showed some radios performing at 1/2 power of vendor spec. Not having to troubleshoot this problem over a period of time on even one long link paid for the meter. It saved our tails." Thanks Chris Cooper Intelliwave, LLC “I had a few faulty units that customers were complaining about poor signal etc and the Praxsym PM-2458 confirmed this. I have had good reports back from the customer who has the first unit saying it works extremely well and takes all of the guess work out of installing a link.” Peter Davison Whywire - Wireless Networking Solutions www.whywire.com.au "The Praxsym meter is the ONLY tool that we have identified that combines the ease of use, portability, accuracy and economy that is needed for installing and troubleshooting our systems in the field. The single highest number of issues in the field related to our products is the poor performance of a transmission system. An RF cable with improper termination, or one that has been damaged, or a bad antenna feed can all present themselves as errors or poor performance on our radio systems. These problems have historically been very hard to troubleshoot. The Praxsym meter allows a technician to easily identify where the problem may be and to eliminate these issues as part of the troubleshooting process. In virtually every instance where I or one of my SEs has used the meter in the field, the installer has purchased a meter immediately afterwards. The ROI for this meter is nearly instant with respect to the amount of time that can be consumed in the troubleshooting process.
