Network Operations & Upgradation

Upgradation / Expansion of existing networks by introducing new equipment from alternate vendors entails critical re dimensioning of the network and reconfiguration of the network elements. This task becomes even more critical when redeployment of existing equipment’s is done on a live network without interrupting ongoing traffic. A high precision coordination is required between the RF Engineering, Network dimensioning, OMCR & I&C teams since the time window available for outage is barely a few hours and generally during night time. Few critical parameters that need to be maintained to ensure consistent delivery to customers during the redeployment activities are:

  • Consistency in pre and post swap RF parameters
  • No change in the traffic carrying capacity of the redeployed network
  • No impact on value-add services being subscribed to by the customer
  • Consistency in the coverage

E-NodeB / OutDoor Small Cell

E-NodeB/Outdoor small cell solutions can also be fully contained in many different existing infrastructures, including bus stops, information kiosks, billboards, street manholes and lamp posts. Connected street offer a great platform for providing seamless connectivity and digital services. They are also a natural part of a wider urban landscape, influenced by local needs and technological innovations.

Sector Addition & Network Upgradation

Once a cellular network has been planned to provide overall coverage, there are a number of ways of adding additional capacity. A simple and cost-effective option is to allocate further radio channels to existing cells. However, this can only be done by an extension band. Other alternatives involve rearranging the cellular plan, either by cell splitting or by sectorization.

Cell splitting is achieved by dividing an existing cell up into a number of smaller cells, by adding additional base stations. It is then necessary to reallocate the radio channels. By repeatedly splitting cells; the cell size, and hence the system capacity, can be tailored to meet the traffic capacity requirements demanded by customer behavior in all areas.
