We have 10 Ceragon links in a mixture of 11Ghz and 6Ghz (low band). The issues we have had are either cryptic enough that Ceragon themselves has no idea what to do about it or their support just flat out sucks. Here is the list:
- We paid for 200mbit license, however the radios seem to max out at 155mbps (they are an STM radio after all). - We have several radios that are not able to output full power it seems. We have a few 6Ghz links that output 30dB while others cannot go above 26dB. Same radio model, same outdoor gear, same cables etc. Ceragon had no answer. When asked about why the links were not able to do this the answer we received in the field was "It's a 50/50 shot". Awesome. Thanks Ceragon. - Ceragon radios with the 10/100 Ethernet interface do not have traffic counters in SNMP. Graphing of traffic must be done via a switch port. - Ceragon support always seems to be either stumped or the person who has the answers to our questions is always "out of the office". - I have yet to receive a proper response on exactly what the procedure is to upgrade firmware on the radios. We have several with issues that Ceragon explained are "fixed" in newer firmware. No idea where to actually GET the firmware either and support seemed clueless about that as well last time I called. The issue we see is that after upgraded to a Gigabit Ethernet interface, we are still unable to get higher than 100mbit/s on our radios licensed for 200mbit/s. Ceragon fixed one of them but we still can only get 155mbit/s out of it. They never told us what they did to fix it and I could never reach the tech who did the work either. I will say this, the links that work properly are fairly rock solid. We have had a couple RFU units die off due to them transmitting at 100% power 100% of the time in order to stay linked up. That is with ATPC enabled. We could never get an answer on that issue either (the antennas were DEAD on alignment). -- Adam Kennedy Network Engineer Omnicity, Inc. -----Original Message----- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Paolo Di Francesco Sent: Tuesday, April 20, 2010 9:36 AM To: WISPA General List Subject: Re: [WISPA] Best Backhaul link 11Ghz 20 miles @ 100MB?
