Notion of Orthogonality in LTE

In FDM, the sub-carriers are separated in the frequency domain to avoid interference between the sub-channels It results in a loss of spectrum efficiency because the frequency guard band can not be used to send data. The OFDM allows one to remove the frequency guard band.   Benefit: There are more sub-carriers, so more symbols … Read more

Why to evaluate operator existing Network condition for InterRAT in LTE planning

Radio planning engineers need to understand the existing operator’s network configuration as well as its footprint. This is particularly important before designing any network that requires commitment on KPIs later. In any Greenfield LTE deployment, there will be a need for InterRAT handover either due to coverage hole within the LTE network or on the … Read more
