★ Frequency re-use is the key factor of cellular network ability for increasing both coverage and capacity.

★ Different frequencies are utilized by adjacent cells; however problem does not arise to determine the cell sufficiently far apart using the same frequency.

★ Reuse distance and the reuse factor are the two elements that influence frequency re usability

★ The frequency is 1/K, where K is the number of cells that cannot use the same frequencies for transmission.
