With Power over Ethernet (PoE) support, the same Category 5 cable that connects your access point to the data network also provides its power. A single cable installation dramatically improves your choice of mounting configurations because you no longer need to consider AC power outlet locations. PoE support makes it easier than ever to overcome installation problems with difficult-to-wire or hard-to-reach locations.

Wireless Network Standards

Understanding the characteristics of the 802.11a and 802.11g standards can help you make the best choice for your wireless implementation plans.

802.11a

Ratified in 2002, 802.11a operates at the 5GHz band and supports data rates at up to 54Mbps. Because there are fewer devices in the 5GHz band, there’s less potential for RF interference. However, because it is at an entirely different radio spectrum, it is not compatible with 802.11b and 802.11g.

The higher spectrum provides about 50m (164ft) of coverage. Consider 802.11a when you need high throughput in a confined space and you are:

■Running high-bandwidth applications like voice, video, or multimedia over a wireless network that can benefit from a five-fold increase in data throughput.
