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.
