Methods and apparatus for channel assignment
View Patent ↗Methods and apparatus for high throughput wireless cells and networks are described. The wireless cells may be equipped with multiple radios. Antennas may be arranged into overlapping and non-overlapping patterns. Channels may be assigned to foster servicing clients, and inter-cell communication. Attenuation may be used to decrease interference. Networks may be formed using a variety of methods and apparatus.
1. A method for assigning channels to a plurality of wireless cells of a network, the method comprising:
identifying a master wireless cell of a network having opposing physical sectors and a plurality of wireless cells, wherein each wireless cells has a shape of coverage similar to a triangle;
assigning the master wireless cell a hop number of zero;
setting a current hop number to zero;
setting a next hop number to one;
identifying a wireless cells physically closest to each of the current hop number cells;
assigning an identified cell the next hop number;
incrementing the current hop number and the next hop number by one;
repeating the identifying step, the assigning step, and the incrementing step until all wireless cells of the network are assigned a hop number;
selecting a channel assignment pattern;
assigning the channel assignment pattern to the master wireless cell and to all wireless cells having an even hop number;
rotating the channel assignment pattern about 60-degrees in a direction selected from the group of clockwise and counter-clockwise;
assigning the rotated channel assignment pattern to all wireless cells having an odd hop number.
2. The method of claim 1 wherein at least two of the opposing physical sectors are assigned the same channel.
3. The method of claim 1 wherein none of the opposing physical sectors are assigned the same channel.
4. A method for facilitating the assignment of channels to network, the method comprising:
identifying a master wireless cell of a network having opposing physical sectors and a plurality of wireless cells, wherein each wireless cells has a shape of coverage similar to a square;
assigning the master wireless cell a hop number of zero;
setting a current hop number to zero;
setting a next hop number to one;
identifying a wireless cells physically closest to each of the current hop number cells;
assigning an identified cell the next hop number;
incrementing the current hop number and the next hop number by one;
repeating the identifying step, the assigning step, and the incrementing step until all wireless cells of the network are assigned a hop number;
forming a nine-cell channel pattern by assigning a channel assignment pattern to the master wireless cell, to each of the wireless cells assigned a hop number of one, and to each of the wireless cells that are substantially adjacent to two wireless cells assigned a hop number of one;
assigning the nine-cell channel pattern to the plurality of wireless cells such that the center cell of the nine-cell channel assignment pattern falls only on wireless cells assigned an even hop number.
5. The method of claim 4 wherein at least two of the opposing physical sectors are assigned the same channel.
6. The method of claim 4 wherein none of the opposing physical sectors are assigned the same channel.
