Hi all,

we are happy to announce the Milestone 1 (M1) release of the LTE module 
developed within the LTE-EPC Network Simulator (LENA) project.

Here is a summary of the new features available in the LTE module with
this release:

  - uplink PHY and MAC properly implemented including Adaptive
    Modulation and Coding (previously only downlink was supported)

  - interference modeling was implemented: it is now possible to
    simulate multi-cell scenarios with inter-cell interference

  - flexible spectrum model: it is now possible to specify the carrier
    frequency and bandwidth of each cell independently

  - an implementation of the Proportional Fair scheduler based on the
    FF LTE MAC Scheduler API is now included

  - support for output of RLC and MAC layer Key Performance Indicators
    (KPIs) via dedicated trace sinks connected to newly defined trace

  - the setting of the most relevant parameters (e.g. tx power, noise,
    carrier frequency, bandwidth, type of scheduler, etc.) is now done
    via the ns-3 attribute system

  - several test suites have been added, including both unit tests that
    check the correct functionality of specific objects, and system
    tests that validate the output produced by the simulator in several
    scenarios of interest.

  - the documentation of the lte module has been entirely rewritten, it
    now features three separate sections: the design documentation, the
    user documentation and the testing documentation.

The source code can be retrieved using mercurial from this address:

A stand-alone version of the documentation in pdf format can be
