We even worked in a lions den! That's right, one of our most memorable installs came when we designed and implemented an outdoor wireless network with multiple access points, HD video cameras, full wireless video streaming support, webcams, a computer based recording and buffering system, a mobile HD wireless cam, and a custom website to feature a 1 month event where a man lived in the den with two 3 year old lions to raise money for the wildlife. The event went viral within a few days, and I'm sure most of you saw it on your local news.
About Installing Wifi:
When it comes to Wifi products and installation, not all Wifi equipment is created equally, and not all wifi installers equally create a well tuned and secure system. Wifi installation is not terribly difficult to understand, but understanding how the signal will react within the given environment through spectrum analysis, locating and working around RF interference, and learning how the equipment responds to these obstacles takes a bit of experience and a proper assortment of electronic and computer based WiFi tools.
Some Wi-Fi signals will easily bounce off of windows, mirrors, metal, and other substrates behind the exterior or interior walls, thus creating weak, limited, or no signal at all. When operating the equipment in different modes, the smallest of obstructions can lessen both network range and performance of the entire system.
Each WiFi installation is different, as all buildings pose their own challenge, either by electrical or structural interference. At minimum, it is imperative that your WiFi installer has the right tools to sweep, analyze, and optimize the Wifi Network, and once the network has been installed, a passive scan of the network should be carefully performed in search of rogue AP's, potential hackers, and other RF interference that may cause potential issues down the road.
In addition to the proper tools and experience, Wifi equipment comes in many flavors, and each has its place in the industry. A properly installed wireless network should consist of wireless equipment that is designed for the installation environment, should be built on the right platform for current requirements and future expansion, and should take in account all obstacles from building structure to environmental RF interference, as this will ensure proper functioning on the equipment side.
A good installer will:
1) Analyze and understand the design needs based upon an inspection of the property and its environment.
2) Turn that analysis into a workable print
3) Ensure the right platform is being implemented based on the clients current and future needs.
4)Take into account any preexisting interference, both RF and structural, and provide an onsite test of the intended equipment before the install, if needed.
4) Install the wireless network system with minimal interference to the client, with minimal disturbance to the property, and within the allotted timeframe given to the client.
5) Test and secure all aspects of the system, and provide the client with a fully detailed report. The report will contain security information, data rates, network maps, signal measurements and much more.
6) Provide show and tell. Our tech will take as much time as needed to properly explain the system and how to use it.
National Data Contractor has years upon years of wireless networking experience, and we know from this experience that a properly installed, analyzed, and secure network built on the right platform will require less maintenance and make for a happy end user!
Whatever your needs are, National Data Contractor can fulfill them.
What are the different types of wireless Frequencies available?
802.11b WiFi up to 11 Mbps (megabits per/sec) with good signal range, but has the slowest transmission speeds of the four. This signal suffers from interference as it uses the 2.4 GHz frequency that many appliances use, and has the lowest connection ability for simultaneous users.
802.11a WiFi up to 54 Mbps has a shorter range than the 802.11b and is more easily obstructed by walls or other obstacles. It uses the 5 GHz frequency which limits interference from other common devices such as appliances, and allows for more simultaneous users. 802.11a is not compatible with the 802.11b network adapters, access points or routers.
802.11g WiFi up to 54 Mbps enhanced signal range, simultaneous user connections and penetration over the above, and is compatible with 802.11b network adapters, access points and routers, but uses the same 2.4 Ghz frequency so it has the same interference issues as 11b
802.11n WiFi up to 600 Mbps depending on number of data streams and hardware support. This wireless network uses multiple antennas and signals for better speeds, allows for more simultaneous user connections, has the best range and penetration with the lowest interference from other devices, can use 2.4Ghz or 5Ghz frequency. Note: It is only compatiblele with with 802.11g when using the 2.4 Ghz frequency and will have the same interference.
802.16 WiMAX (Worldwide Interoperability for Microwave Access) uses the frequency range of 2-11 GHz and 10-66 GHz. It is a high speed wireless technology for delivering high speed internet services to large radius areas of 30 miles at 1 Gbit/s for fixed stations, though realistically more around 4-6 miles. It is part of the 4G wireless communications. Although WiMAX offers blazing transfer rates up to 75 Mbit/s to a single user, its signal must be split for multiple users and therefore reduces its speed. Even when split to between several hundred homes that speeds are at least equivalent to cable modem rates. WiMAX can be used in a number of applications at greater distances over WiFi such as cellular backhaul, hotspots, broadband connections, VoIP, IPTV, last mile broadband access and more.
