It seemed reasonable at the time. I briefly used a DEC Multia with two Aironet LM4500 PCMCIA wireless cards as a point-to-point backhaul and access point. That was a lot of money for hardware but the cable company wanted tens of thousands of dollars to bring coax a very short distance to the site, and ADSL in those days was still something you could expect to deliver just 128kbps upstream under ideal conditions.
