For better or worse, more and more Portlanders are relying on cell phones and wireless devices providing internet access.  There are nearly twice as many wireless subscribers as "land line" phone customers in Portland.   The FCC estimates that wireless phones are the source of over 70% of call to the 9-1-1 emergency communications center.  Dependable access anywhere and everywhere, without signal loss, is viewed by many as essential.  As technology here is mobile, access to the technology has very little to do with demand or interest in any particular neighborhood - it has far more to do with the right and ability of the carrier to provide an adequate signal to mobile users wherever those users happen to be in the service area, regardless of neighborhood.  Reliable wireless access depends on signal availability.  Increasing numbers of wireless users means more antennas are necessary to provide reliable signals.  Unsurprisingly, some citizens prefer such facilities to be located away from residential neighborhoods.  Opponents site sincerely-held concerns about potential health impacts, aesthetic issues, and property values.  There are others who support wide availability of access to wireless choices, and regard such availability, along with good connections and competitive pricing, as an asset to the City and its neighborhoods.
