WiMAX or LTE for small city broadband service?

Howdy all!

I was thinking about bringing broadband to a small countryside city (around 60K inhabitants) my parents lived in, in Brazil. It's been some time that I last worked in the telco business, so I'm in need of a head start.

The scope is a bare home/small business wireless broadband service. Absolutely no frills, just internet access.

The technology candidates are WiMAX an LTE. I know the performance and range differences, but I'd like to know from the elders how both measure up in terms of the infrastructure costs/complexity and lifespan.

Thanks in advance!
