Carphone Warehouse Blames Wireless for Fixed Broadband Sales Dip

You might not be surprised if a broadband access provider blames either housing or economic sluggishness for lower than expected unit growth, in the U.K. or U.S. markets. So it's probably no big deal that Carphone Warehouse blames a housing slowdown for lower take-up of additional broadband lines.

But note this tidbit: Carphone Warehouse also says "mobile broadband sales" are partly to blame for lower fixed broadband sales, warning it expects lower revenue next year if the trend continues.

So the question logically arises: are some U.K. consumers substituting wireless broadband connections for fixed connections?
