Wireless Devices with Propiatary protocols

Dear all,
I guess you are familiar with "Motorola Canopy SM/AP", it uses its own propieatary protocols and very stable Wireless Device but expensive one. DO you know some other Wireless Devices which has its own propiatary protocols as Motorola Canopy ? and can be used as Outdoor Unit ???

Everything that is not using 802.11 is 'proprietary'.

Is there something specific you are looking for that Canopy isn't able to provide?

I am concerned about Price, so i was looking for Alternative to Canopy...

If u know some devices then please suggest... Thanks
