A broadband connection is a high-speed Internet connection. Broadband usually has a data transmission rate of 265 Kbps (kilobits per second) or greater. The term broadband simply means a broad band of frequencies has been used. It is a radio term and normally means that multiple frequency carriers are used to carry one signal. It describes the way ADSL (Asymmetric Digital Subscriber Line) services work so has become a term to describe a fast internet connection. Broadband is a high-capacity transmission technique using a wide range of frequencies, which enables a large number of messages to be communicated simultaneously. Broadband internet is typically anything faster than dial-up (cable, DSL, etc.) and in other words it provides high speed internet. WiFi is a technology that uses radio waves to provide network connectivity. ... WiFi is NOT the Internet itself. What's the difference between broadband and Internet? The fundamental difference between dialup and broadband Internet connections is the manner in which the connection is made from your PC to the Internet. The modem in your PC "calls" an Internet Service Provider (ISP) and connects with a maximum speed of 56,000 bytes per second, better known as a 56K speed connection. On the other hand when you see cable companies advertising their high-speed internet, they usually refer to it as Broadband. DSL and Cable Internet access both offer an “always-on” connection to the internet. They both provide speeds greater than any you'll ever see on a dial-up connection.
