1. Improved Speeds
Wi-Fi speeds have improved from the maximum
of 11Mbps with 802.11b to as much as 300Mbps
or more with the 802.11n standard. Since signal
strength can have a major effect on speed, creating
better coverage areas through multiple access points
(APs) and improved antennae can do as much to
improve speed as a standard with higher through-
put. There are a couple of caveats with the higher
speeds. First, 802.11n has gone from 50Mbps to
300Mbps through the use of techniques including
multiple-channel multiplexing, but those may not be
compatible from brand to brand, causing devices to
default back to the base level throughput. Further,
there are two frequency bands, 2.4GHz and 5GHz.
Many APs will use both frequencies, but doing so
on a single AP can reduce throughput.
Laptops used to be the only devices on the com-
pany's wireless network. But Wi-Fi has become a
ubiquitous standard used by a host of devices-inclu-
ding desktop PCs, laptops, netbooks, tablets, smart-
print
joli phones, printers, storage devices, and projectors.
To determine whether you need to update or im-
prove your Wi-Fi network, you need to know which

2. Improved Coverage
good idea to enable additional security. Many APs
allow for multiple groups of users, so you can set
up a separate guest network that allows access to
the Internet, but not to local resources such as file
servers and printers.
Security standards have become easier to set up
and harder to crack over the last few years. The
newest standards can automatically exchange keys
with new devices on the Wi-Fi network, but may not
work as easily with all devices with older operating
systems such as Windows XP.

Newer devices can handle higher throughput; better
coverage, signal strength, and security; and even
segregate traffic to protect your wired network from
unauthorized users or bandwidth-hogging traffic. If
you're getting complaints about the network from
users of Wi-Fi devices, review the new devices that
are available, and see which ones will best fit your
needs.
