LTE Strategy

LTE – Important Strategic Decisions to take


Radio Access Technology Planning Inter-Technology Radio Planning

requires tools to support multiple technologies simultaneously in same project Support for Shared Antenna Systems

Interim Voice Services such as CSFB are dependent on have 2G/3G coverage co-incidental with LTE

Inter-RAT multi-technology features such as: simulated/live traffic capture, neighbour planning, PCI planning

Joint planning of Tracking Areas in LTE and Location Areas in 2G and 3G

Automation, including Live update of configuration parameters from network keeps planning tools in sync

Voice Calls (CSFB) likely to fail in this area due to coverage/quality


Important to dimension and plan on an end-to-end basis from Radio Planning tool (e.g. AIRCOM ASSET®) across backhaul (e.g. CONNECT®) and the network (e.g. I-VIEW DIMENSION)

Technology evolution => LTE higher network elements are supported (SAEGW, MME) Ability to create the LTE logical interfaces (S1-SAE, S1-MME, X2) Realization of the LTE mesh topology (an eNodeB can belong to more than one SAEGW or

MME) Inter-technology operation Actual and simulated traffic

from different sources (GSM, UMTS, LTE sites) is created and carried over

LTE Planning and Optimization Complexities


High number of LTE cases need to be analyzed

· f-Band A· Channel bandwidth

· Different radio networks sharing same antenna

· Individual antenna tilts· 2G + 3G + LTE· High complexity· Traffic Sharing· Multi RAT Handover· Sharing equipment· Service level optimization· HetNet· Different traffic maps· Different traffic growth· Etc.
