Wi-Fi Deployment

Wi-Fi Wireless LAN

Wireless Local Area Networks (WLAN), known as Wi-Fi, allow workers to stay connected to an organization's network, allowing them real-time access to information whether they are at their desk or on the move. Wireless Ethernet link / Wi-Fi technology provides cost savings and creates flexibility with rapid deployments and expansions, without the high cost and time needed for traditional cabling. Employees become more productive when they can access information when and where they need it, whether they are using the internet, using email, or accessing a corporate database. Wi-Fi can support both voice and data. Wi-Fi provides instant, effortless connections for desktops, laptops and handheld devices.

WLAN's are made up of wireless access points (AP's) that are connected to the LAN. AP's are radios that use IEEE's 802.11 technology, that is commonly represented as 802.11b (2.4GHz @ 11Mbps), 802.11g (2.4GHz @ 54Mbps), 802.11a (5GHz @ 54Mbps) and now 802.11n (using either 2.4GHz or 5GHz @ up to 300Mbps). A single enterprise class AP can support roughly 40 plus users at any given time. Wireless Ethernet technology is extremely secure when implemented properly.

Wireless connectivity and wireless mobility has become a way of life. Today most everyone is carrying a mobile device and expects to have high speed wireless bandwidth everywhere they go. In many cases, people now have more than one wireless device carrying around their smart phone and their tablet device (e.g. iPad). A major problem in the wireless industry is when wireless networks get overloaded due to the high density of users on a local network. This problem becomes even greater when you have events that have thousands of people all trying to get online with their wireless devices all at the same time. Cellular networks can get slammed. This is why many carriers try and off load people onto Wi-Fi hotspots in order to free up the demand for their 3G / 4G networks.

A rule of thumb is to have a max capacity of 40 active Wi-Fi users on an access point at any given time. Now many manufactures have pushed that limit by using various techniques like timing algorithms, but as a general rule for high performance 40 is a good number. In high density wireless applications the thing to remember is that even if everyone is not trying to use their wireless handheld device, the devices still beacon the network. This causes a lot of traffic and overhead to an access point.

So what happens when you put thousands of people in a small area all trying to get a wireless Ethernet bridge using Wi-Fi connectivity? If you do the math you would have to add a lot of wireless access points in an area to handle the load. With Wi-Fi 802.11b/g 2.4GHz there are only three non-overlapping channels. In Wi-Fi 802.11a there are 8+ depending on the channel widths. Most all devices will try and use the 2.4GHz 802.11b/g Wi-Fi first by default. With only three non overlapping channels it becomes difficult to put a lot of AP’s next to each other in a small place, especially if the AP’s are using omni directional antennas. You have to do strict channel and power planning. Done correctly though a Wi-Fi network can free users to be more productive and mobile.

It can be less expensive to install a wireless Ethernet / Wi-Fi network than to run cables and install jacks throughout a facility, especially for organizations that need flexible and scalable network architecture. According to Gartner, the cost for deploying and managing a wireless network can be anywhere from 15%-40% lower per employee versus wired alternatives for some companies.


Deliver high speed data with minimized interference, multiple layers of security, transmitted for long, medium and short distances, around obstacles and over water. 


Deliver high speed data where hubs are equipped with transmitters/receivers that supply two-way bandwidth on-demand to a large number of buildings within a service sector. 

Based on your unique requirements, NetTarius will determine appropriate frequencies and range requirements to provide you with the appropriate products,  whether it be Point to Point or Point to Multipoint) including flexibility, performance and affordability to meet your current and future needs.


Deliver high speed internet access through a power outlet equipped with a modem connected to your computer.  Provide broadband services to your multi-dwelling unit and business simply and cost effectively.

Cable LAN Networks

Deliver high speed internet access by leveraging the use of existing electrical distribution lines, twisted pair copper wires and coaxial infrastructures to create a communication network.


Provides a way to connect and exchange information between devices such as mobile phones, laptops, PCs, printers, digital cameras over a secure globally unlicensed short-range radio frequency.

Personal Area Network (PAN)

A computer network used for communication among computer devices including telephones and personal digital assistants (PDAs) close to one person.  A PAN typically reaches a few meters and can be used for communication among personal devices or for connecting to a higher level network and the Internet.  PANs may be wired with USB and FireWire.  A wireless personal area network (WPAN) is made possible with network technologies such as Infrared Data Association (IrDA) and Bluetooth.


A broadband wireless metropolitan access network (MAN) that uses a point to multipoint architecture.  WiMax defines the use of bandwidth and frequency ranges and the MAC layer that supports multiple physical layer specifications customized for the frequency band and their associated regulations.  WiMAX supports very high bit rates in both uploading to and downloading from a base station up to a distance of 30 miles to handle such services as VoIP, IP connectivity and TDM voice and data.

Radio Frequency Identification(RFID)

An RFID system consists of an antenna and a transceiver that reads a radio frequency and transfers the information to a processing device and a transponder or tag, which contains radio frequency circuitry and information to be transmitted.


Satellite broadband offers two-way Internet access via satellites.  Your computer through a special satellite modem, broadcasts requests to a satellite dish that sits on top of your business.  The dish then sends and receives signals from satellites that orbit above the equator.  As long as your dish maintains a clear view of the southern sky (in the U.S.) you receive broadband Internet access.
