1. Does anyone have any experience with the XtremeWave MPR Series from PCTEL/MaxRad? 2. Can anyone comapre the PacWireless offerings to the XtremeWave MPR Series? I suspect the MPR's are more expensive/ 3. Some of the MPR's have side lobes that make alignment challenging. In this case we ar

You guys should know that the 802.11 radios I have worked with can have built in attenuators, sometimes more than one, that can get switched on and off based on RX power level sensed in hardware. How many and at what levels the attenuators kick in varies from card to card and vendor to vendor. O

I can recommend both versions of Mohawk cable. The burial cable is very stiff because of the thick plastic inner jacket. The aerial lash cable is the one I have the most experience with. Both cabled are flooded with silicon "goo" on the inside. It is messy but it cleans up very easily with an or

The link LED and all other LEDs for Ethernet Jacks/Connections are driven by the Ethernet PHY chip or the Ethernet chip itself the PHY is integrated. Link is turned on by the PHY sensing the LIT (link integrity test) in 10BaseT which I believe has become part of the auto-negotiation protocol in

Which cable or kind of fill are you using? If it's the silicon fill from Mohawk you can easily clean it with an orange cleaner and that could help. leb At 10:20 PM -0400 3/17/10, Robert West wrote: >I use flooded cable exclusively. Have you tried another make of crimper? >Maybe you aren't get

Re: [WISPA] Ubiquiti Sector Tilt angle

2010-03-29 Thread Lawrence E. Bakst
Technically speaking you're wrong. The highest gain area of a sector antenna is the center point between the horizontal and vertical spreads. If you don't downtilt you are sending the strongest part of the signal parallel to the horizon. Why would you ever want to do that? The whole reason you

I think you guys know most of this already, but here is my take FWIW. I'm not a WISP, but I spent 5 years leading the design and development of an 802.11[agb] security system. We did our own polling solution based on 802.11e HCCA to solve the RTS/hidden node problem. All things being equal (whi

Mike, If you can set your application up to be more switching than routing based you could consider the new Arista switches. Very high 10 GbE port density with low cost. You don't specify what kind of routing you are doing but if it is BGP they have that in Beta now. I have no idea what the rou
