[PLUG] [OT] NYTimes article: What Carriers Aren’t Eager to Tell You About Texting
|
http://www.nytimes.com/2008/12/28/business/28digi.html
I thought this part was interesting enough to warrant an OT topic:
"Perhaps the costs for the wireless portion at either end are high —
spectrum is finite, after all, and carriers pay dearly for the rights
to use it. But text messages are not just tiny; they are also free
riders, tucked into what's called a control channel, space reserved
for operation of the wireless network."
