    All 3G sites are supposed to be candidates (to be selected/activated)GSM sites :

    are already existing, and share same antennas (E tilt not linked)

    can be reconfigured during UMTS site selection

    Site Selection Process for LTE Third Scenario-

    Deployment scenario with potential candidates, either defined with their

    coordinates in database or based on existing GSM/UMTS sites

    Candidate site location (X/Y) for LTE can be :

    Added in site table as location only

    Imported as a list (text format) directly in ACP

    Automatically created from location of existing GSM or UMTS sites

    Reconfiguration of Station template parameters is user defined

    Atoll ACP associates candidate location with Station template types, according to

    geographical area (ie Urban/Rural station depending on area)

    Common multi band antenna (UMTS/LTE) can be allocated to new LTE sites to

    link sectors

    Optimisation Setup / Third Scenario

    Principles of Site selection based on New candidates

    ACP calculates path loss matrices of candidates at beginning of optimisationprocess (only once)

    LTE Sites are always reconfigured when selected

    Control of existing Layers (avoid degradation of quality)

    Flexible settings

    Zone Weighting (focus on specific area, ie dense urban)

    Objectives weighting (RS Coverage vs RS CINR) Objectives per zone (Focus, Hot spot, group of clutter class..)
