Re: [WISPA] Long 5Ghz link over water
Have a look at our Radwin2000 MIMO radio- the diversity option is specifically for these applications.

Schafer o...@odessaoffice.com: It's probably ducting. Where the conditions in the AIR literally bend the signal over or under your receive antennas. You'll likely have to put in a system designed with something called antenna diversity. Basically two antennas for each link. One 10 to 20' higher than the other one. Then the radio will listen to the two of them and switch to the one with the greater signal levels for it's data flow. I always wanted to try this using a splitter placed EXACTLY in the middle of the two. But with wave lengths so small I don't think it's likely that I'd get it close enough without a lot of blind luck (get it wrong and you create multipath inside the cables). Exactly. My thoughts went to an 802.11n card, with two antennas on each end. WISPA Wants You!

Re: [WISPA] cellular repeater/bidirectional amps
Jason, BDA (Bi-Directional Amplifier) and DAS (Distributed Antenna System) systems for In Building applications- are more reliable and carrier class than Wilson, etc... Expensive though. What range does your Femtocell give you?] One thing they all have in common is they require a good clean originating signal from a near-by cell site. Otherwise, they amplify the noise as well. Two questions: What is the maximum range of your Femtocell? Do they need a boost for one carrier or multiple?

Now, since we're the local gurus of all thing wireless, one of our customers is wanting something comparable for a larger area in an rf unfriendly building (large metal building with various metal additions). It may be necessary to have multiple cellular boosters to provide the indoor coverage they need. I'm studying the various brands at Tessco, and they include the wi-ex series, Wilson, and Digital Antenna Inc. Seems these are amps, do I need to be concerned about feedback between systems if these are within earshot of each other? I know the outdoor antenna has to be sufficiently isolated from the indoor antenna to provide the gain, which shouldn't be a problem based on the type of construction.

The cost for radiax, mounting hardware, connectors, etc make it really cost prohibitive in an open air area. Radiax is best served in tunnels and corridors/ hallways as there is no gain factor, only loss. We have installed it up to 1800 GHz for PCS repeaters but I still prefer antennas and taps.

[WISPA] FW: RAD/Radwin x Wi-Fi
Answer to Rubens' post on September 18th. Please let us know if you have any further questions regarding the Winlink1000 or Radwin2000. Matt Musial Radwin, Director of Sales Cell- 562-659-1358 Radwin's radios consists of 802.11a or 802.11n modem chipset wrapped up with proprietary radio technology, powerful processor and software based signal processing algorithm. Every single radio goes thru comprehensive testing including burn in to validate compliance to the specification across temperature range. The result is robust high performance carrier class radio: - Low constant latency regardless of distance (important for WISPs who plan to offer voice and other real time services) - High PPS (packet per second) capability - Very low packet error rate (PER) and bit error rate (BER) even under interference. - And much more All that is offered at unmatched unbeatable price! Yes there are some vendors that brag about their proprietary technology. However proprietary technology does not guarantee performance and reliability. But it is defiantly ensures high cost as they cannot leverage on the economy of scale that off the shelf modem offers. Ilan Moshe, EE President Radwin Inc. -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Rubens Kuhl Sent: Thursday, September 17, 2009 9:13 PM To: WISPA General List Subject: [WISPA] RAD/Radwin x Wi-Fi I'm trying to figure out what's under the hood of Radwin Winlink-1000 / RAD AirMux-200 and the MIMO model Radwin-2000 / RAD AirMux-400, in order to better understand what traffic patterns may or may not be suited to these radios. Although costly backhaul vendors (Redline, Motorola) keep telling me that RAD/Radwin are Wi-Fi based, my testing of them insist on telling me otherwise... for instance, AirMux-200 pass with flying colors thru RFC-2544 performance testing with maximum performance (18 Mbps) even for 64 byte frames (27 kpps), which is a very good pps rate compared to the 2kpps of a Ubiquiti Nanostation (non-M). Data rates are indeed similar comparing AirMux-200 to 802.11a, although Radwin tops at 48 Mbps air rate, not 54 Mbps; the MIMO model have data rates that look very much like the MCS8-15 802.11n data rates, suggesting that there are indeed some Wi-Fi heritage in the product, no matter what the tests say.
