The Aironet 1250 Series Access Point with one RM1252 radio module installed requires 12.95W, which is within the 802.3af Power over Ethernet (PoE) standard. Any Cisco switch supporting 802.3af may be used to power the Aironet 1250 Series Access Point with one RM1252 radio module installed. This is ideal for businesses that chose to only deploy on a single frequency (2.4 GHz or 5 GHz). A single radio provides optimum performance with approximately 300 Mbps maximum PHY data rate. Customers who deploy dual-band, 802.11n radios and power the 1250 Series using standard 802.3af will have more reliable and predictable coverage than that provided by traditional 802.11a/g networks; however, operation will be limited to a single transmitter per radio with maximum PHY data rates of 150 Mbps instead of 300 Mbps per radio. Customers with a significant investment in 802.11 a/b/g client devices that have low-to-medium bandwidth needs but high-reliability requirements will benefit the most from this type of deployment scenario.
