SELECTION TOOL FOR ACCESS POINT POSITIONS

EKAHAU OY, (FI)

1. A computer implemented method comprising:receiving environment information comprising at least planning area definitions, information on propagation obstacles in the planning area, and access point installation height;
dividing the planning area into plurality of location topological cells;
calculating for each location topological cell a plurality of metrics of different types, wherein the plurality of metrics provides values for different properties of a radio signal coverage pattern, one metric providing one or more values for a single property;
converting each metric to a metric score;
calculating for each location topological cell a location score from a plurality of metric scores corresponding the plurality of calculated metrics for the location topological cells wherein a location score is a value depicting the quality of a corresponding location topological cell as an installation point of an access point with the access point installation height; and
storing at least temporarily the location scores associated with corresponding location topological cell for a computerized wireless network planning tool to provide information for determining of final locations of access points in a wireless network that is being planned.

WIRELESS NETWORK PLAN WITH MULTI BAND ACCESS POINTS

EKAHAU OY, (FI)

1. A computer implemented method comprising:receiving at least a first frequency-band-specific network plan for a network and a second frequency-band-specific network plan for the same network, each network plan defining in the network plan initial physical locations for radios of the corresponding frequency band to place the radios in the network, the radios representing physical access points in the network;
creating a set of pairs, in which a pair contains a radio from the first frequency-band-specific network plan as a first element representing an access point in the network and a radio from the second frequency-band-specific network plan as a second element representing an access point in the network, the set of pairs containing a plurality of pairs so that there is for each radio in the first frequency-band-specific network plan a pair with each radio in the second frequency-band-specific network plan;
assigning to each pair a utility;
selecting a subset of pairs that maximizes a sum of utilities and contains any radio from the first frequency-band-specific network plan and from the second frequency-band-specific network plan at most once; and
creating a merged network plan by performing, for each pair in the selected subset of pairs, placing radios in the pair into the same radio group, which represents a physical multi-band access point in the merged network plan for the network, and selecting a physical location of the radio group in the network plan based on physical locations of the corresponding radios in the first and second frequency-band-specific network plans, the physical location of the radio group indicating where to place the corresponding multi-band access point in the network.
