Recently I was going through the LTE deployments over the globe, and I found that a good number of LTE deployments are on 2.6GHz band. Compare this to Indian scenario - Pvt. players got spectrum on 2.3 GHz band and BSNL is shouting they are given spectrum on non-standardized 2600 MHz band. Compared to global scenario is it not the fact that pvt. players got non-standardized band while BSNL got standardized band if we think about roaming like conventional GSM spectrum is 900/1800MHz which enables global roaming in most of the countries? Secondly in US Verizon is offering LTE on 700 MHz band while Teliasonera in Scandinavia offers LTE on 2.6GHz band. So if we import a Verizon LTE smartphone it will not work with Indian LTE operators, not only for mismatch of frequency band but also for LTE technological differences. [in US Verizon launched LTE-FDD while Indian players are keen to go ahead with TD-LTE]. In Germany Vodafone is to launch LTE on 800 MHz band - So CDMA players in India can offer LTE on their existing spectrum, right ? At the same time some operators also plan to launch LTE on 1800 MHz band - So GSM players with much spectrum on 1800 MHz can roll out LTE on their existing spectrum, right ? Both are possible because LTE is compatible with many bands unlike GSM,W-CDMA & CDMA ranging from 700 t0 3500 MHz. We also do not know Indian LTE players will offer LTE on dongles via SIM (llike GSM) or no-SIM (like CDMA-EVDO dongles). So better we do not bring LTE devices from other countries to use it in India. I like to have some expert comments from RIMweb Gurus to clear my confusions!
