WiSpire is already available
I'm reading this article over a wireless broadband connection hosted by my local parish church.
It is meshed with other church towers to a point were real connections are available.
Church towers are tall - its common to be able to see several from the top of one.
It works and it beats the pants of the 3mpbs offered by rebundled OpenReach coverage - I'm 200 yrds from the local exchange but we have no date for an upgrade.
