An interesting question. 
And one that deserves an answer - I just don't have one.
Been having the same problems and that's with G and N 2.4 and 5.7 with
inteligent software to select which frequency to use to share the load
between four persons.

However, we have 14 networks visible, and constant retraining is making
the 100 mb p/s more like 10 kbs per second.

I wonder if the ACMA have a plan for future deployment possibilities. 
Other countries ghave planned for expansion by using 2.4-2.7 and CDMA.
