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

High number of LTE cases need to be analyzed
· f-Band A· Channel bandwidth
(1,4MHz …20MHz)· Expected traffic

and Coding Schemes· Channel overhead· MIMO (2x2, 4x4, …)· Used antenna technology
(individual antennas)· Vendor specific settings & thresholds· Multi RAT deployments· Etc.
· 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.
