Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
Today its established that WiMAX is primarily running in the 2.5GHz and 3.5GHz bands, meanwhile LTE is still not as decided and looks like most LTE operators will either utilize the 2.5GHz band or refarm their 900MHz spectrum.
Having said that, its true that low frequency bands such as the 900MHz or the newly opened 700MHz offer better RF propagation but in the same time these band are limited in the number of available carriers, GSM900 carrier is 200kHz while LTE is looking at carriers of 10MHz and 20MHz to deliver the promised high throughput. 3G had to be moved up to the 2.1GHz for similar reasons.
From other points of view, both LTE and WiMAX adopt OFDMA which has better spectral efficiency and an all-IP architecture which means that an upgrade from 3G to LTE is as complicated as from 3G to WiMAX, it remains to see if WiMAX gathers enough supporter from equipment manufacturers which today is a losing struggle for WiMAX.
