FUN LTE has been designed as a comprehensive planning tool to satisfy operator requirements for network planning and optimisation. Its newly designed user interface is intuitive and provides easy access to a rich feature-set of planning functionality. FUN supports large operator networks for a multitude of wireless technologies in large regional office deployments as well as small work-group configurations. FUN LTE is being used by large technology driven operators to plan and optimise 3G networks. It is available as a stand-alone product, or as part of the FUN wireless network-planning suite of tools.
Principle Features include:
The LTE module utilizes all the foundation functionality as described in the FUN GSM.
This includes:
– Intuitive user interface
– Comprehensive multi-technology data model
– Wide range of Macro / Micro / Pico cell propagation models including ray tracing model
– Powerful interference algorithms
Algorithms
– Coverage Planning
Coverage planning is essentially based on results of field strength predictions, normalized to RS power. Besides standard displays
– Best server areas
– Best server (RS) field strength
– Cell assignment probability
– Interference (1:1, 1:n, n:m)
LTE specific displays are provided:
– Quality of service
– Data rate
The use of data mining (coverage DB) provides enhanced performance of displays.
– Parameter Planning:
Main targets of LTE parameter planning are:
– Neighbour relations, especially from and to GSM, UMTS
– PCI
– PRACH
Parameter planning is based on a chain of consecutive calculations:
– Cell Assignment Probability (CAP)
– Interference Matrix
– Neighbour Relations
– PCI Planning
– PRACH Planning
In calculation of interference matrix and neighbour relations overlapping best server areas based on CAP results are used which provides a more realistic scenario.
– Automatic PCI Planning:
Automatic PCI planning is based on interference matrix. PCIs are optimized with respect to interference relevant parameters which are cell identity, RE position of RS and PCFICH and – of course – PCI.
– Automatic PRACH Planning:
In automatic PRACH planning the following parameters can be determined automatically:
– cell radius
– zero correlation zone configuration
– PRACH configuration index
– PRACH logical root sequence number
Based on interference areas determined in IMatrix optimization is done with respect to overlapping areas of subframe numbers determined by PRACH configuration indexes and overlapping areas of PRACH logical root sequence numbers. The special planning algorithm of high speed cells is available.
