NEW YORK: US cable television giants Comcast and Time Warner Cable have said they will not enter the bidding fray for the Federal Communication Commission's analogue wireless spectrum sell-off.

The auction, which begins in January, paves the way for a complete digital switchover in the US in 2009. The airwaves being sold are considered ideal for wireless broadband.

Comcast says it eschews the sale because it is already part of a consortium that bought wireless spectrum last year and "has many strategic options".

TWC also owns some additional wireless spectrum through its participation in another consortium, but has not yet decided what to do with it.

Among those that have declared their intentions to take part in the FCC sell-off are Google, startup firm FrontLine Wireless and cable operator Cox Communications.
