I have a lot of Deliberant CPE in my network, just a few of their
APS. But the newer generation stock with Atheros cards supports
20/10/5 MHz channels.
From their site, concerning the Duos:
Product contains:
* Dual-Radio with adjustable RF Output Power
* Rugged cast aluminum hinged enclosure
* Full, half, and quarter bandwidth channels
* Multi-BSSID support (VSSID) with VLAN tags
* PoE built-in for single cable installation
* Configurable Multi-mode AP
* AP mode/AP client mode
* WDS
* AP router/AP client router
* AP repeater
* Redundant PtP bridge with STP
