Improving Coverage for a Given Service Area

Some common practices to improve the coverage for a given service area are:

  • Receiver selection. Selecting an eNodeB with a better receiver sensitivity will help to improve the coverage for a service area.
  • Implementing receiver diversity. In UL highers, the chances of correctly decoding the received signal from the UE improve the coverage.
  • Beamforming.  For uneven heights, beamforming can be a very handy feature to compensate for any coverage hole.
  • Improving the antenna gain. This is particularly useful for smaller cells, wherein the DL cell radius is limited in comparison with the UL cell radius.
  • Adding more sites. In case none of these techniques can be used to compensate for a coverage hole, the last option would be to add a new site.
