Cable AML has delivered a Wireless HFC Extension to provide 54 to 870 MHz downstream service plus 5 to 42 MHz return for Cable Modems and Interactive Set-top boxes (STBs) between the master headend and a subscriber pocket at a distance of 14 miles (22.4 Kms).

Cable operators are selecting two-way AML microwave links for two-way plant upgrades because in many situations microwave has significantly lower cost than fiber. For example, the system recently delivered by Cable AML has a LOS (line of sight) distance of 14 miles, which is equivalent on the average to twenty miles (32 Kms) of fiber. Depending on terrain and other factors, fiber can cost more than twice the cost of the two-way AML link.
