text: It looks like HSDPA is getting more popular, with data transmission rates of 4 to 5 times that of current generation 3G networks (UMTS) and 15 times faster than GPRS.\nAnd UWB can deliver data rates in excess of 100 Mbit/s, while using a small amount of power and operating in the same bands as existing communications without producing significant interference. However it is not limited to wireless communication, UWB can also use mains-wiring, coaxial cable or twisted-pair cables to communicate - with potential to deliver data faster than 1 gigabit per second.\n\nThough it looks like HSDPA is getting more popular, we may need to wait for a while to see which one of them will integrate into daily life seamlessly.
