LTE Issues

Light Reading published an article based on discussions from the LTE World Summit. Carriers there identified a number of issues that need to be resolved before they deploy LTE, including:
  • Support for voice and SMS services including circuit switching as well as packet switching.
  • Building enough back haul capacity into the network to realize LTE's performance promises.
  • Intellectual property rights.
  • Spectrum
Much of this discussion revolved around lessons learned from 3G. It does point out the real problems carriers will have rationalizing both their 3G and 4G strategies. I think that they will either stay with 3G or replace their 3G networks with 4G networks. I think that trying to provide both will be a real mess.

    Let's see what the Japanese do. They led on 3G. They will also lead on LTE. The UK will follow several decades behind and its politicians will claim world leadership as they sign contracts using taxpayer's money with Chinese vendors. Meanwhile UK taxpayers will be paying bank bonuses and using dial-up over GSM.

    Verizon in the U.S. also promises to be on the leading edge with LTE. The CDMA operators are looking for a way out. The WiMAX deployments in both countries are providing some additional impetus.
