Comment WiFi is ready for a comeback. (Score 1) 259
The basic problem is the cost per square mile was too high. To get anywhere near 100% indoor coverage required 40 AP's per sqare mile. With AP's costing $1500-$11000 and engineers starting out saying that only 16 AP's per square mile, companies got into it, found out service sucked, then added more AP"s. By the time they got it right, they were out of money at $100-$200K per square mile. There just wasn't enough market to support a multimillion capital expenditure. The trick is to do some actual RF engineering instead of listening to manufacturers and network engineers who had a 4 hour class and were now RF experts, as to how many AP's were really needed. Then do a real business model and quiti giving it away for free (Metrofi was the dumbest idea out there, free Wifi in exchange for reading ads which kept competitors out). With new AP's costing as little as $100 and 802.11N specifications, it's time for WiFi to come back.
