Abstract

A method, system and computer for determining placement of at least one antenna of customer premises equipment in a fixed wireless access network are disclosed. According to one aspect, a method includes generating a map of signal strength for each of a plurality of possible antenna locations among one or more buildings. The method further includes identifying a percentage of a building having a level of wireless network coverage. The method also includes identifying a location of an antenna based on the map of signal strength and the identified percentage.

First claim

What is claimed is:

1. A method for determining placement of at least one antenna of customer premises equipment in a fixed wireless access network, the method comprising:
generating a map of signal strength for each of a plurality of possible antenna locations among one or more buildings;
identifying a percentage of a building having a level of wireless network coverage, the identifying including calculating a ratio of a length of covered segments to a perimeter of the building; and
determining a placement of antenna locations based at least in part on the map of signal strength and the identified percentage such that a distribution of antennas among dwellings of one floor of the building determines a distribution of antennas on at least one other floor of the building.

2. The method of claim 1 , wherein the level of wireless network coverage is one of a downlink throughput threshold and a signal to interference plus noise ratio, SINR, threshold.

3. The method of claim 1 , wherein the identifying of a percentage of a building having a level of wireless network coverage includes estimating segments of the building which receive wireless network coverage.

4. The method of claim 1 , further comprising classifying a building as one of a single dwelling and a multiple dwelling, the determining of the location of an antenna for placement being affected by whether the building is one of the single dwelling and the multiple dwelling.

5. The method of claim 4 , further comprising, when a building is classified as a multiple dwelling, calculating a number of floors of the building and a number of dwellings per floor, the determining of the location of an antenna for placement being affected by a number of floors of the building.

6. The method of claim 5 , wherein a number of dwellings is derived based on a perimeter of the building and a probability of non-livable space within the building.

7. A computer for determining placement of at least one antenna of customer premises equipment in a fixed wireless access network, the computer comprising:
processing circuitry configured to:
generate a map of signal strength for each of a plurality of possible antenna locations among one or more buildings;
identify a percentage of a building having a level of wireless network coverage, the identifying including calculating a ratio of a length of covered segments to a perimeter of the building; and
determine a placement of antenna locations based at least in part on the map of signal strength and the identified percentage such that a distribution of antennas among dwellings of one floor of the building determines a distribution of antennas on at least one other floor of the building.

8. The computer of claim 7 , wherein the level of wireless network coverage is one of a downlink throughput threshold and a signal to interference plus noise ratio, SINR, threshold.

9. The computer of claim 7 , wherein the identifying of a percentage of a building having a level of wireless network coverage includes estimating segments of the building which receive wireless network coverage.

10. The computer of claim 7 , further comprising classifying a building as one of a single dwelling and a multiple dwelling, the determining of the location of an antenna for placement being affected by whether the building is one of a single dwelling and a multiple dwelling.

11. The computer of claim 10 , wherein when a building is classified as a multiple dwelling, calculating a number of floors of the building and a number of dwellings per floor, the determining of the location of an antenna for placement being affected by a number of floors of the building.

12. The computer of claim 11 , wherein a number of dwellings is derived based on a perimeter of the building and a probability of non-livable space within the building.

13. A method for determining placement of at least one antenna of customer premises equipment in a fixed wireless access network, the method comprising:
generating a map of signal strength for each of a plurality of possible antenna locations among one or more buildings;
identifying a percentage of a building having a level of wireless network coverage, the level of wireless network coverage being one of a downlink throughput threshold and a signal to interference plus noise ratio, SINR, threshold, the identifying of a percentage of a building having a level of wireless network coverage including:
estimating segments of the building which receive wireless network coverage; and
calculating a ratio of a length of the covered segments to a perimeter of the building; and

determining a placement of antenna locations based at least in part on the map of signal strength and the identified percentage such that a distribution of antennas among dwellings of one floor of the building determines a distribution of antennas on at least one other floor of the building.

14. The method of claim 13 , further comprising classifying a building as one of a single dwelling and a multiple dwelling, the determining of the location of an antenna for placement being affected by whether the building is one of a single dwelling and a multiple dwelling.

15. The method of claim 13 , further comprising using a tuned propagation model to generate a throughput plot for downlink and uplink signaling that satisfies a minimum coverage requirement for each distinct antenna placement, the throughput plot being generated with a bin resolution on an order of meters.
