Network types

Computer network types can be categorized by scale or range, connection method, functional relationship, network topology or specialized function, among others. We will focus on the most commonly used classification: by scale or physical size.PAN (Personal Area Network)

Purpose

PAN networks link devices such as smartphones, tablets, PDAs, printers, laptops or desktops, by cable, for data transmission within

LAN (Local Area Network)

Yes, known as WLAN network (Wireless Local Area Network) the nodes are connected through Wi-Fi technology or Bluetooth and can reach a distance of up to 20 km. 

MAN (Metropolitan Area Network)

Purpose

MAN networks are similar but larger than LAN networks (in fact MANs connect LANs to one another at high speed).
These networks are usually designed for towns and cities.

WAN (Wide Area Network)

Purpose

A WAN network is an unlimited set of LAN and MAN networks connected to each other.

GAN (Global Area Network)

Purpose

GAN networks are composed of different interconnected WAN networks, the best example of this type of network is the global positioning system (GPS).

what is a wan

what is a wan? A wide area network (WAN) is a telecommunications network that extends over a large geographical area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits

WANs do not just necessarily connect physically disparate LANs. A CAN, for example, may have a localized backbone of a WAN technology, which connects different LANs within a campus. This could be to facilitate higher bandwidth applications or provide better functionality for users in the CAN.

WANs are used to connect LANs and other types of networks together so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private. Others, built by Internet service providers, provide connections from an organization's LAN to the Internet. WANs are often built using leased lines. At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. 

wifi monitoring tools

In today’s world an IT organization, you’ve seen wireless networks quickly evolve from a convenience offered to employees to a mission-critical component of your IT infrastructures. Wireless users now expect comparable performance and availability to wired networks.

Organizations enjoy the flexibility of Wi-Fi network access; however, it poses a host of challenges for network managers. Most managers lack the tools and visibility to effectively monitor their wireless networks, much less make informed planning decisions and proactively manage their performance.

Monitoring wireless performance is more complex than wired networks. The range of wireless access points (APs) can be affected by a number of issues, including building materials. As more users connect to a wireless access point and it is oversubscribed, performance begins to degrade. And as APs age, their performance begins to decline.

The Manage Engine Wi-Fi Analyzer and Surveyor can be used to effectively monitor signal strength and display channel graphs on all available Wi-Fi networks. You can use the Wi-Fi monitoring tools to detect slow Wi-Fi networks and identify channel interference and poor signal strength.

wi fi support

Operating system  Wi-Fi support is the support in the operating system for Wi-Fi and usually consists of two pieces: driver level support, and configuration and management support. Configuration and management support consists of software to enumerate, join, and check the status of available Wi-Fi networks.

Wi-Fi is wireless LAN, It is one of the important technologies of the computer networking, It allows the users to connect to the internet technology without the wires, It allows the router to be cordless also, The network is connected through an access point for internet and it is connected to a USB Port.

Wi-Fi   is a family of wireless networking technologies, based on the family of standards, which are commonly used for local area networking of devices and Internet access. Compatible devices can network through a wireless access point to each other as well as to wired devices and the Internet.

wifi management

WiFi Network Manager's are administrative software / applications that are used in controlling, manipulating and configuring the various devices on a wireless network. User managers are a typical example of network managers as they are used for granting access and monitoring the various members of a network.

Wifi management provides WiFi internet access for guests, residents and employees throughout a property. The design typically include devices such as wireless controllers, wireless access points, switches and extensive cabling.

The WiFiTel Network Manager is packaged enterprise standard hardware and software components integrated into a unified system with a cloud interface.

Designed for large networks with a high density of WiFi Access Points the WiFiTel Network Manager includes advanced features that set it apart from other WiFi network management systems and ensure that problems affecting user quality of service are automatically prevented, resolved or mitigated.

managed wifi providers

The days of spotty connectivity and Internet cables are far behind us; these days’ people expect instant connectivity .And when it comes to a business setting, quick and easily accessible Wi-Fi connectivity is not just about ease of business, it has tangible benefits such as enhanced productivity, efficiency and teamwork.

In the past decade, the business WLAN scenario has changed completely; from managing a few access points (AP) to provide wireless hotspots for a small number of employees, office Wi-Fi is now expected to provide complete enterprise-wide coverage to hundreds and thousands of users.

To manage this new scale of wireless connectivity demand and to ensure that scores of employees, guests and users are provided instant and secure connectivity, Managed Wifi providers, enterprises need to rope in professional service providers to manage their Wireless LAN.

Cloud based Wi-Fi services is the way forward; the entire WLAN ecosystem is managed remotely by the service provider ensuring a secure, scalable and stress free Wi-Fi network.

A managed WLAN solution is more than just managing user access, it can comprise the entire life cycle of WLAN – from designing, engineering and installing the wireless systems to managing the entire network. Cloud managed Wi-Fi uses a flexible subscription based payment model to deliver centralized management for authentication of users and network monitoring.

wifi support

WiFi support is the name of a wireless networking technology that uses radio waves to provide wireless high-speed Internet and connections. Wi-Fi networks have no physical wired connection between sender and receiver by using radio frequency technology -- a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space.

Wi-Fi's wavebands have relatively high absorption and work best for 

line-of-sight use. Many common obstructions such as walls, pillars, home appliances etc. may greatly reduce range, but this also helps minimize interference between different networks in crowded environments. 

Wi-Fi is potentially more vulnerable to attack than wired networks because anyone within range of a network with a wireless network interface controller can attempt access. To connect to a Wi-Fi network, a user typically needs the network name .The password is used to encrypt Wi-Fi packets so as to block eavesdroppers. Wi-Fi Protected Access (WPA) is intended to protect information moving across Wi-Fi networks and includes versions for personal and enterprise networks. Developing security features of WPA have included stronger protections and new security practices.

Wifi support provides service in private homes, businesses, as well as in public spaces. Wi-Fi hotspots may be set up either free-of-charge or commercially, often using a captive portal webpage for access. Organizations, enthusiasts, authorities and businesses, such as airports, hotels, and restaurants, often provide free or paid-use hotspots to attract customers, to provide services to promote business in selected areas.
