Advantages of 700 MHz spectrum over a 2500 MHz spectrum

Just like somebody explained long back... " lower the frequency longer the distance" ...   :-))

It is a proven theory that a LTE 700 MHz is going to be a killer in case of LTE Services before 450 MHz can make a pitch in the competition. Because many of the major LTE markets are already having strong push to deploy 700 Mhz spectrum.

Both FDD/TDD modes are available in 700 MHz spectrum.

The below pictures are self explanatory of benefits/advantages over other spectrum...

LTE / LTE-A :- Integarted / Dedicated PGW

Many vendors are proposing an integrated SGW/PGW platform approach for operators, who just started rolling out LTE Networks. Combining both SGW+PGW in same hardware platform ( more specifically, the ever promising ATCA) has advantages over dedicated platforms.

The operator should decide whether to deploy the combined/dedicated platform according to their own projected traffic over their planned coverage.

For some operators who don't want piggyback their LTE traffic on existing 3G/2G platforms can opt for a dedicated infrastructure for LTE GWs (May be from different vendors). But in future if they decide to Upgrade their existing GGSN platform to have GW potentialities then  they should be careful in choosing their combined SGW+PGW Node for the present situation.

The important part is that integrated node should be able to offload part of the traffic on S5 interface to the upgraded GGSN (to PDN-GW) node. This is in a way will ensure the investment protection for existing infrastructure.

What is your view ?....
