The high speed debate is mostly fiber centric , but the solution to cheapper and quicker deployment is the mobile BB solution. The 3g 4G and future 4.5g technologies will allow to provide 30 and 100 Mb at 1/50 of fiber deployment. And the microwaves wimax tecno with the exixting fiber deployment could solve the transport needs.
The fiber deployment is very expensive and could create a bigger digital divide because a lot of rural and poorer people will not have cocerage as consecuence of capex and opex.
Last mile radio access is the solution.
