New iPad or iPad 3 or iPad 4G is launched in US and supports 4G network in US. New iPad 4G LTE is supported only on AT&T and Verizon networks in the U.S. and on Bell, Rogers, and Telus networks in Canada. [specs details]
Worldwide 2G voice services are generally offered over 900MHz & 1800 MHz by GSM operators, while CDMA operators use 800 & 1900 MHz spectrum. For 3G services (WCDMA, HSPA, HSPA+, DC-HSPA) GSM operators use 2100MHz, while CDMA players can offer high speed EVDO services on existing 2G spectrum. This is general standard, so global roaming is easy for GSM and CDMA operators, though GSM is widely accepted compared to CDMA. But as we see to global deployment of LTE, there is no such standardization of spectrum band like we see with GSM and CDMA. It may cause problem with global roaming of LTE with a single device.
Do not buy a new iPad 4G if you are living in India. Because in India currently no operators offers 4G services. Secondly iPad 4G supports FDD-LTE on 700 MHz and 1700/200MHz spectrum band.
