It would be nice to have an integrated solution like RB951U/G but with 5Ghz or dual band.
As 2,4Ghz becomes more saturated and more newer client devices support both bands it would be really usefull to have an integrated Routerboard device that could work on 5Ghz for soho deployments.
I know it can be build using RB935/RB435/RB433 boards, an enclosure, a mini-pci radio and a couple of dipoles but the costs for large deploys (20+) is significanty higher, and the mounting time makes the costs even higher. It would be an excesive cost (components and mounting time) to use a DIY device instead of an integrated product.
