iPhone 3G reception problems
August 25th, 2008
Repeat after me: the plural of “anecdote” is not “data”.
After a lot of blustering, internet forum posts, upset fanboys, and threats of lawsuits over the iPhone 3G’s alleged reception problems, some people with equipment and knowledge tested it an discovered its radio performance to be essentially identical to the Nokia N73 and the Sony-Ericsson P1.
It has to be, it has to conform to GSM and CDMA specs otherwise it won’t work at all, there is a set spec for power levels and it will be in constant comms with the netowrk about it’s Rx and Tx power levels. CDMA especially, if there is any issue with the power levels and/or timing it can bring the whole cell down!
Amusingly I had a piece of kit in my car today that would test that!
