Clearwire has begun selling PC cards to let Seattle customers access its broadband service without having to lug around a modem, according to InfoWorld.

The card will easily fit into a laptop, bypassing the modem, which has to be plugged into an outlet.

According to InfoWorld, anyone can visit a Clearwire store in the Seattle area and sign up for the portable service. After rebates, the PC card, made by Motorola, costs $80. Monthly service costs $60 (compared with the $42 charge for the bulky modem) and offers 1.5Mbps download speed.

I reported in August that Clearwire was going to start testing the PC card in a few unspecified markets. It makes sense to test it on their home turf.

At the time, the company also said it will test in the same markets a faster residential connection speed at 2 megabits per second (Mbps), bursting up to 4 mbps, for $44.99 a month (that compares with 1.5 Mbps and 3 Mbps for the top-speed plan).
