Get to Know More About WiFi Hotspots

www.xsinfosol.comTechnological development in the information and communication technology sector has in the past seen the rise and popularity of two types of network connectivity options, i.e. Wi-Fi and hotspot. In a professional term, Wi-Fi also known as wireless fidelity can be defined as a wireless local area network component that is based on IEEE 802.11 standards. Its main function is to enable PCs using the device to connect to the internet or a wireless local area network without the need of a physical connection, i.e. cable via a wireless router (a network interconnectivity device that links two different LANs). Assess to wireless area network using Wi-Fi can either be open, i.e. anyone can use the network or closed, i.e. password authorization is required.

Geographical areas covered by wireless networks are commonly referred to as hotspots in the network technical terms. Users in hotspot zones are provided with access to the internet via a wireless router that acts as an uplink to the internet through an internet service provider. In order to access the internet in a hotspot zone, you need to have either a laptop or a cell phone that is Wi-Fi enabled. Whereas, this was a luxury for a few in the past, demand and competition has seen laptop manufacturers include Wi-Fi as a network connectivity option.

Hotspots can be located in the hotels, supermarkets, air ports, public libraries, hospitals, universities and colleges. Nevertheless, due to the rapid development of internet technology most governments have plans to have cities covered by hotspots to enable the millions of people living in those areas have an easy access to the internet, wherever they are.

Wi-Fi hotspots can be classified into two main classes, i.e. free Wi-Fi hotspots and commercial hotspots. Free hotspots can either be open public network, i.e. the wireless router in the hotspot zone can be shared by any user that is within the operating radius of the wireless network. The only lacking thing in this type of Wi-Fi network connection is that there is no control whatsoever on the use and access of the wireless router.
In closed public network hotspot zones, a control standard, i.e. hotspot management system is utilized to manage the hotspot connection. The application is installed and run from the wireless router or from another computer not used in the network. Using the program, administrators can limit the number of users who can gain access of the hotspot area and to restrict bandwidth usage thus enabling equal distribution of surfing speeds. Commercial hotspots, on the other hand, charges some specific amount of fee either through credit card or iPass or any other form of payment that users may find suitable.

Security in hotspot zones, however, is not guaranteed as the only types of security measures that may be available could be user authentication or virtual private network. To safeguard your data and system from the security risk such as packet sniffers when in the hotspot zone, install and update regularly reliable security software, e.g. firewall.
