Why Operators require Spectrum Reframing in LTE

Here I write down one basic idea of Spectrum reframing in LTE and why operators require spectrum reframing for LTE. Operators worldwide are looking forward to new LTE technologies deployment but not every one of them possess brand new spectrum…

3GPP Services Classification and EUTRAN Capacity Limiting Factors

Here I write on 3GPP Services Classification and EUTRAN Capacity Limiting Factors for LTE. 3GPP Services Classification Being a data centric technology, LTE has well defined classifications for Quality of Service. In general, there are two main classes of service…

What is Margin of Interference in LTE?

Margin sites intrusive noise levels due to an increase can be considered as If sites were spaced closer together than position using the same frequency The thermal noise floor. In other words, the system is interference limited as Opposed to…

Indoor deployment and optimization of the system after deployment

After completion of the design, installation takes place. For aesthetic reasons, the components of a closed system is often deliberately hidden. As a result, after installation, it is difficult to confirm or check them in full. Skill during installation, therefore,…
