The thing is there are cases or palces where Wireless cant be made reliable for a specific situations that limit that location. People will remember those rare cases and associate them with Wireless in general, without understanding that taht is a different situation and not the norm. People blaim Wireless or the wireless provider for a lot, but its rarely the Wireless's fault.
You'd also be surprised how often Sonet Rings wont properly route the other direction around the ring, when a failure occurs, based on the type of failure. The Fiber Ring is a physical redundancy method, but it doesn't mean that the intelligence part over top it will properly direct the traffic. Its also hard to get a fiber carrier to truthfully disclose the full inner workings of their network, for the buyer to verify a claimed redundant path will truly offer full redundancy. The only way to know for sure, and guarantee it wont change over time, is to do it yourself, or work with someone small enough who is not afraid to show the proof. For example, for some of my customers, I'll map out hop per hop the path their data will go both primary and backup path. I'm not saying I give redunancy ever, because there are many places my network is not redundant. But I could built it redundant and PROVE IT, when customers were willing to pay for that. For Fiber,. If I want guaranteed redundant Fiber transport paths, they will charge me for two circuits, double the price. And I could get better diversity if I jsut deployed two wireless links to diverse paths. So To compare reliabilty of Wireless to Fiber, its really only an apples to apples comparison if we compare a single wireless link to a non-redundant single fiber path. For example, a Wireless ring could jsut as equally be created to compare against a Sonet ring. At the end of the day, the only thing Fiber gives us is more capacity when that capacity is actually needed. Unless of course, LOS cant be achieved, or distance to long for the technology. But the worst travisty in public perception is that the public often associates Wireless with the lowest technology capabilty. Fixed PTP wireless should NOT be bundled into the same category as PtMP Wifi.
