Wi-Fi Guest

It’s a facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area using radio waves.

Signal Strength refers to the WiFi signal strength indicator on your mobile device. Data throughput refers to the speed at which data is transferred within the WiFi network typically rated at Mbps (Megabits per second). So depending on which WiFi router or WiFi access point you have, data throughput will range from 2Mbps right up to 1.3Gbps.

Interference can come from a number of sources. i.e. building material and obstructions such as metal, brick and glass; electrical appliances such as microwaves, cordless phones and cell phones; interference from neighbouring WiFi routers and access points; poor placement of the WiFi router or AP, typically next to the TV, telephone line, etc.

Contention internally from multiple WiFi enabled devices such as smartphones, tablets, laptops, gaming consoles, etc; WiFi router and access points may be limited as per the manufacturers specifications and may not match your requirements; contention externally on your ISP service where the service may be shared with many other users (data throughput may also vary by time of day); and it stands to reason that if you have multiple users and devices competing for the same bandwidth then the initial bandwidth will need to be divided multiple times.

WiFi currently uses 2.4 GHz and 5 GHz radio frequencies to connect the devices to the WiFi network. 2.4 GHz has a larger range thus allowing you to access the WiFi further away from the WiFi router or WiFi access point, but data transfer at this frequency is limited to 300Mbps. This is fine for handling daily tasks like web browsing and social networking. In addition, the 2.4GHz band offers 11 channels within this band with channel 1, 6 and 11 being the most common. The limited number of channels make the 2.4 GHz band susceptible to radio interference.

WiFi gives us freedom from wires, but it’s not secure by default. Data is transmitted through the air, and anyone nearby can easily capture it with the right tools. Employing security measures is necessary to protect files, online accounts, and user privacy.

There are a variety of options available to extend and improve your WiFi coverage, namely, wireless access points designed to handle low, medium and high density environments or WiFi repeaters whereby the existing WiFi signal is expanded throughout a building by plugging WiFi repeaters into any available power socket. Repeaters are available for both the 2.4 GHz and 5 GHz frequencies. Power line adapters are also able to extend your WiFi coverage. They utilise your existing electrical network to extend the coverage of your network.
