In an earlier post, I had written about the challenge that the iPhone 5 and this generation of phones face when it comes to operating across a fragmented LTE spectrum in international roaming scenarios.
Huawei just announced its Ascend P1 LTE Smartphone describing it as the device compatible with the highest number of frequency bands in the LTE spectrum.
In a recent article in Fierce Wireless, Phil Goldstein surveyed the complexity of supporting LTE spectrum bands in the US
‘Apple plans to sell three different models of the iPhone 5 to support various LTE bands. The GSM version designed for AT&T Mobility will support AT&T’s 700 MHz B Block as well as AWS Band 4 (2100/1700 MHz), which is used in Canada by Bell Mobility, Rogers and Telus. The CDMA version for Verizon Wireless and Sprint Nextel supports Verizon’s 700 MHz C Block spectrum and Sprint’s 1900 MHz LTE service as well as three international LTE bands: 850 MHz, 1800 MHz and 2100 MHz. The international GSM version, which will be used by EE in the United Kingdom, among other operators, sports those same three international LTE bands’
The LTE Roaming challenge is hotting up and operators introducing LTE smartphones need to consider this as a key requirement that could become the differentiator in the 4G Smartphone market. One can see a lot of LTE roaming agreements being signed up in the near future.
