A number of spectrum allocation decisions, spectrum standardization decisions, spectrum availability decisions, technology innovations, component development, signal processing and switching enhancements and inter-vendor cooperation have to take place before the vision of 4G will materialize. We have the experiences of previous generations especially that of 3G, this will be useful in guiding the industry in this effort. Few factors that should be undertaken are as follows:-
Lower Price Points Only Slightly Higher than Alternatives
The business visionaries should do some economic modeling before they start 4G hype on the same lines as 3G hype. They should understand that 4G data applications like streaming video must compete with very low cost wire line applications. The users would pay only a delta premium (not a multiple) for most wireless applications.
More Coordination among Spectrum Regulators around the World
Spectrum regulation bodies must get involved in guiding the researchers by indicating which frequency band might be used for 4G.
More Academic Research
Universities must spend more effort in solving fundamental problems in radio communications especially multiband and wideband radios, intelligent antennas and signal processing. Standardization of wireless networks in terms of modulation techniques, switching schemes and roaming is an absolute necessity for 4G.
Integration Across Different Network Topologies
Network architects must base their architecture on hybrid network concepts that integrates wireless wide area networks, wireless LANS. Broadband wireless networks must be a part of this integrated network architecture.
Non-disruptive Implementation
4G must allow us to move from 3G to 4G.
