Sartre Project: Is Wi-Fi an Existential Threat to Telcos?
Jean-Paul Sartre died in 1980. There were fewer than a thousand cellphones in the world. The World Wide Web was a decade away. He's the most prominent existentialist philosopher. There's no obvious connection between his work and this analysis of the impact of Wi-Fi on telephone companies.
As I write in August, 2015, it's not clear whether the panic telcos are demonstrating about Wi-Fi is justified. Verizon is running scared about the risk they face from Wi-Fi offload. That's the most powerful signal that WiFi is a real threat. On the other hand, Cisco and AT&T continue to project 40%-50% growth in data demand for four or five years at least. I haven't seen any convincing data to the contrary.
Realworld likely speeds of 50-150 megabits 90+% of the time. Two 20 MHz bands will deliver speeds like this. You rarely will need that kind of speed but higher capacity wireless means more bandwidth for all. The 2 gigabyte and 5 gigabyte caps need to disappear and they will where there's enough competition. 55% of Singapore is covered now and they'll be close to 100% next year. 
Vodafone buys 110 MHz in German auction, DT 100 MHz. DT & Vodafone already offer 50-100 megabit LTE, which will increase in the next few years to a gigabit. LTE Advanced in the lab delivers over a gigabit in 100 MHz of spectrum, 5 channels of 20 MHz, 8 x 8 MIMO.
