(2.4GHz - Use for internet access only)
applications, 802.11b, which operates at 2.4GHz is sufficient.
It is the most widely accepted standard of the three, and is
most deployed. The price of 802.11b equipment is also the
cheapest, due to the demand of 802.11g. The distance of 802.11b
will rely mostly on whether or not the communicating devices
have line of site or not. The less obstacles in between the
transmitting and receiving devices, the better the wireless
connection will be, which translates to better web surfing.
If you are using your
wireless router/access point only for internet connectivity
then this wireless standard is good for you. This is because
your connection to the internet through your broadband modem is
only operating at best about 2Mbps (depending on your service
area), which is still very fast. Your 802.11b devices can
transfer data up to 11Mbps, which is therefore sufficient for
So, if you are using
wireless for internet only, stick to 802.11b. It will save you
equipment, give you great speed on the web, but is being phased
out by 802.11g
(2.4GHz - Use for
internet access and file sharing)
This standard is
replacing the widely accepted 802.11b standard, due to the fact
that the frequency on which it operates is the same, and price
has dramatically gone down on products. Like the 802.11b
devices, products using this standard will usually need line of
site, to function at optimal performance.
802.11b and 802.11g
both work under the 2.4GHz frequency range. This means
that they are inter-operable with each other. All 802.11g
devices can communicate with 802.11b devices. The advantage of
802.11g is that you will be able to transfer files between
computers or networks at much faster speeds.
If you are using your
wireless connection to transfer files around the home or
office, whether it be data files, music, video, or voice, you
want to go with the 802.11g. With the home audio and theater
moving to wireless networks, you want to be sure to have an
802.11g network setup in your home.
This standard also
allows for some manufactures to have devices working at speeds
108Mbps, which is recommended if you plan to transfer large data
within your LAN.
(5GHz - Use for crowded 2.4GHz area or backhaul)
With this standard
having a different frequency then 802.11b and 802.11g, it
is used mainly in backhaul applications, such as long distance
building to building links, and Wireless Bridge Connections. It
has a higher frequency, so line of site is not depended on as
much as 2.4GHz,but it also does not travel as far without high
offers complete 5GHz Wireless Bridge Kits for backhaul, and long
range wireless applications.

This standard can
transmit at speeds up to 54Mbps, but the equipment will cost more
then 802.11b and 802.11g equipment. One of the benefits is that
you can use 802.11a
in conjunction with 802.11b/g. This is because the frequencies
are different therefore
allowing 802.11a(5GHz) to operate in a crowded 2.4GHz range.
