Sounds like they bought 2.4ghz equipment and are having to return it and get all 5.8ghz and 900mhz equipment which is what they should have done in the first place.
Nothing like pulling that out of thin air. What is your basis for stating they bought 2.4? What is your basis for saying they should use 5.8 and 900mhz? You have none.
Every area is different. There are plenty of areas 2.4 works fine, plenty of areas it doesnt; plenty of places 5ghz doesn't work and more places 900mhz doesn't work than 2.4 and 5ghz combined.
