Only good experience with them. The radios just work. Some were 11 GHz, some were 18 GHz, only one or two 7.5 GHz. Throughput matched the nominal 200/300/400 Mbps for small packets; for large packets, 170 out of 200 Mbps and 360 out of 400 Mbps; those values are consistent with "IP-based" (not SDH/PDH) radios (they are not 140 or 155 Mbps multiples), but is the total opposite of what we would usually expect, as it is easier for the radio to deal with small packets, not harder. Considering the Internet traffic has 50% of 64 bytes packets, that would make the I-mix throughput pretty close to nominal; the monitoring software has RMON capabilities so you can see your packet size distribution in real time.
Adaptive modulation worked hitless for reducing speed during rain periods, but not every time it would go up again. It was a 50-50 chance that ACM would bring the modulation up again, so it's an index you want to be looking at your NOC. We did some firmware upgrades without issues; license upgrades were trickier and sometimes Ceragon had to generate license files again after we've sent the output from the failed upgrades. Except for 7.5 GHz units all the models had integrated antennas; we regret boughting those from RFS instead of Andrew, but Ceragon offered both and the decision was based on price... :-( Rubens On Tue, Apr 20, 2010 at 10:35 AM, Paolo Di Francesco <paolo.difrance...@teleinform.com> wrote: > Just curious, > > what about Ceragon?
