When military radar causes fixed broadband wireless interference
This article is part of the Network Evolution issue of February 2012 Vol. 3, No. 1
We established a RF link (using an Infinet router) to connect two locations about 40 KM apart with fixed broadband wireless. It was working fine for 2 weeks and suddenly it started going out for 2 to 3 hours and coming back on automatically. The ISP is telling us this is due to military radar operating in that area. If it is due to a radar issue what are the possible solutions? Do you have a question for our experts? Submit your question directly to our editors at firstname.lastname@example.org It is quite possible that your ISP has landed on the root cause of your problem. Military radar and commercial Wi-Fi systems have been known to cause co-interference with each other, as the military C-band occupies frequencies in the range of 5290 to 5925 MHz, overlapping with the IEEE 802.11a wireless local area network standard allocations of 5150 to 5725 MHz. Likewise, the Military E, F, and G Bands occupy frequencies from 2 to 6 GHz, which overlap with the radio frequencies allocated to many Fixed Broadband Wireless Access (FBWA) ...

Military radar may cause fixed broadband wireless interference. This expert tip explains tests and ideas to check if this is the case and how to address this interference.
Network bloggers have a lot to say, but do we care? We should. In the top ten network blogger opinions of 2011, our experts poke holes in TRILL, OpenFlow and 10 GbE optimization.
Migrating to 40 GbE will require network performance testing that will take into consideration backplane throughput, jitter and the needs of an FCoE environment.
News in this issue
Packet analysis may provide a deeper look into the network, but NetFlow analysis can offer a broader view. To achieve even better network visibility the two work best together.
Until now the DevOps movement has been lead by systems administrators, but now network engineers may find it also eases network automation and cloud orchestration.
