Internet Infrastructure is not owned by one single organization, rather it’s a co-existence & co-working of many collaborative network infrastructural elements, bind together with standard industry practices, as defined and documented by international standard authorities like Institute of Electrical and Electronic Engineers (IEEE), Internet Engineering Task Force (IETF) etc. There are four major categories of these networks, in building a successful internet infrastructure throughout the world. The largest one is Wide Area Networking (WAN), which connects buildings, neighborhoods & cities, and can even spans over national and international barriers. The physical connectivity in WAN is done mostly with Ethernet or Fiber Optics wiring. But it could be wireless too, in which case it uses Microwave, Infrared (IR) Transmission Technology, or even Satellite.
Metropolitan Area Networking (MAN) helps connecting end points in distant locations within a metro, such as the TV vans communicating with the central office. This is not being used heavily since most of the residential and business facilities need internet connections at fixed locations, and the internet backbone today is very extensive, exhaustive, and robust in reaching the last miles of those residences or business facilities. Rest of the demands seeking mobile connectivity are served by either cellular broadband (3G, UMTS, LTE, Wi-Max etc.), or Wi-Fi mess.
Local Area Networking (LAN) connects the computers, phones, and other devices within a local area, and it is widely used in any businesses. LANs generally uses the internet backbone to get the connectivity to the world, and uses its own intra-office network for intranet and other communication within the office network. Lately, these communications are also being carried out over Wireless Local Area Networking (WLAN), which comprised of the network elements with IEEE 802.11a/b/n/ac chipset (such as Wi-Fi Access Points).
Personal Area Networking (PAN) serves very close nit communications, generally on or well below 100 feet ranges. Bluetooth is one of the most popular technologies in this category.
WAN and MAN are not in the scope of our work. It’s generally provided by the local and inter-city internet infrastructure providers at the physical layer, and ISPs etc. for other layers. Kong Telecom builds the LAN infrastructure through cable wiring, setting up routers & switches, and verifying/testing the connectivity.
Kong Telecom also provides the WLAN connections through the mounting & installation of Access Points, and optimization of the in-building wireless infrastructure through proper positioning of Access Points throughout the building.
