Introduction• In the area of cellular wireless communication, policy

makers have made mistakes due to lack ofunderstanding of the latest technologies and itsevolution

• Examples include:– Allocating spectrum according to a particular technology– Non-futuristic allocation of spectrum– Regulations/Policies that restricts technology– Allocating the same band of spectrum for different

technologies

•This way, after receiving a series of OFDM symbols, as long as theguard time is larger than the delay spread of the channel, eachOFDM symbol will interfere only with itself and ISI will be reduced.

How to avoid Inter Symbol Imterference?

• Insertion of guard time between each OFDM symbol

•This way, after receiving a series of OFDM symbols, as long as theguard time is larger than the delay spread of the channel, eachOFDM symbol will interfere only with itself and ISI will be reduced.

• To have correctable problem of self interference (red above) we use CP.

Regulatory and Policy Consideration of LTE

• LTE can work with the existing technologies andin many different frequency bands.

• The UHF band (300 to 3000 MHz) is consider thebest for land based mobile communication due toits propagation characteristics (in terms ofrange/coverage)

• However, lesser bandwidth is available at lowerfrequencies

• With the finalization of its work on the “Vision” for 5G systems, ITU has nowdefined the overall goals, process and timeline for the development of 5Gmobile systems. This process is now well underway within ITU, in closecollaboration with governments and the global mobile industry

• The next step is to establish detailed technical performance requirements forthe radio systems to support 5G, taking into account the needs of a wideportfolio of future scenarios and use cases, and then to specify the evaluationcriteria for assessment of candidate radio interface technologies to join theIMT-2020 family.
