I just would like to show, the bandwidth we have to cover. Quad band GSM plus UMTS 2100 in one antenna system is still a challenge. Anyhow, we will be glad to guideline you with recommendations on antennas and with design in aid as well. Do not hesitate to come back with further questions by email.
i think 2g is only suitable for india, the 3g equipment is not available in all places
Sundar, 2G is very popular in Europe as well. It is cheaper, has less power consumption and has much better coverage then 3G.
