Wireless Network Technology
Why use Wireless Technology?
Most business buildings today are hardwired with CAT 5 network cabling.
However, wireless technology, which has become more the standard, holds substantial value
both logically and financially.
For example, wireless networking
technology would make much more sense in a building where running CAT 5 cables would not be
feasible such as a retail location. Wireless technology makes it much easier
for expanding a network as well particularly for network based IP
surveillance camera systems. This could save a business owner hundreds, or
thousands of dollars in installation fees alone.
Another common use of wireless technology is to
"wirelessly bridge"
two adjacent buildings together without the need for expensive and complex
ground works.
There are two major categories for wireless
communications
-
Wireless LAN (also known as
WLAN):
A LAN which stands for Local Area Network, is hardwired using CAT 5
networking cabling over short distances and
normally indoors. A WLAN would be the wireless equivalent while
maintaining the same standard networking protocols.
-
Wireless bridges
When it is necessary to connect buildings or different groups of networks
together, a wireless bridge equipment could be used. This can be a point-to-point
or point-to-multipoint scenario capable of long distance wireless
transmission. Also see Long Distance Wireless Networking below.

Wireless LAN standards
802.11.n
The latest standard providing maximum speed and distance with up to
450 Mbps and higher on 2.4 and 5Ghz bands.
802.11g
Fairly new standard providing improved performance compared with 802.11b. Up
to ~24 Mbps actual throughput at up to 100 m/300 feet in outdoor
environments. It uses the 2.4 GHz band. Theoretical bandwidth is 54 Mbps.
802.11b
The most commonly used standard, providing up to ~5 Mbps actual throughput
at up to 100 m/300 feet in outdoor environments. It uses the 2.4 GHz band.
Almost all products on the market support this standard. Theoretical
bandwidth is 11 Mbps.
802.11a
Standard using the 5 GHz band providing up to ~24 Mbps actual throughput at
up to 30m/100feet in outdoor environments. Limited range of products
supporting it. Theoretical bandwidth is 54 Mbps.
Wireless Network IP Security Camera Systems
Wireless technology is the best choice for IP
based video surveillance systems. There is just no comparison between
wired and wireless from an installation standpoint, wireless wins hands
down. The Wireless technology advancements as of 2011 have make wireless the
only choice for surveillance camera systems.
Below is an example of a typical installation
scenario of a wireless IP based video surveillance system. The focal point
is the wireless access point shown in this drawing. Once the wireless
infrastructure is in place, it can be used for any compatible wireless
device.
Wireless Networks
inside the Office
For the reasons mentioned at the top of this page, a wireless network has
become the standard in most office buildings. The ease of installation, and
availability of very high speed wireless equipment make it the only choice
with configuring an office network . Connect the data server, network
printers and the internet with all of your computers throughout your office,
all
wirelessly.
Wireless Network
Security
Due to the nature of wireless communication in general, an unsecured network
would allow anyone with a wireless
device within wireless range, to connect to your network. This is where
wireless network security comes in. All wireless networking equipment now
offers several security protocols. The most common referred to as WEP
(Wired Equivalent Privacy), WPA (WiFi Protected Access), WPA2
(WiFi Protected Access II). These security settings are set inside your
wireless router at the time of your wireless router installation.
Wireless security uses different levels of "encryption"
depending the type of wireless equipment you are using. To put is
simply, the encryption is like a 2-part wireless key. The router has one
have of the key, your wireless device, a laptop for example, would contain
the other half of the key. Without both parts of the key matching, there is
no connection. The encryption key is typically a 10 digit key and uses
either 64bit or 128 bit encryption levels.
Long Distance Wireless
Networking
Transmitting a wireless signal over
great distances has become more feasible with the advent of special
long range wireless ethernet equipment. This expands the wireless
capability greatly allowing a user to send a wireless signal up to a mile
or more away! This is most commonly used to connect remote buildings or
the installation of wireless video camera systems. Below is an example of a
long distance wireless camera system. not the CLIENT and HOST equipment. The
distance between these devices, line of site, can be up to 1 mile apart.
This type of wireless technology allows the installation of a video
surveillance system, in any remote location.
