Frequency Reuse

[mahdi]

Hi friends
What's the meaning of x1:x2:x3 (e.g. 1:1:3 or 1:3:3) frequency reuse pattern?

LTE sites deployed by using 3 sector. Each sector operates on the same carrier frequency. Nomenclature for this reuse pattern is 1 x 3 x 1. This range of frequency reuse represents a number of sites in a template re-use, the number of sectors in each site, and the number of channels on the site.

For example, consider a 1 x 1 x 3 Frequency reuse pattern.

• The first digit (i.e. 1 x 3 x 1) is the number of sites used in the template to reuse frequencies assigned again. For LTE, the first digit is always equal to 1, which means that the frequencies are reused in each site.

• The second digit (i.e. 1 x 3 x 1) is the number of sectors, to deploy at each site.

• The third digit (i.e. 1 x 3 x 1) is the number of channels or transporters, distributed by sectors of each site.
