Question

What is the difference between WiFi and broadband

Answer 1

WiFi is a type of networking. Broadband is a type of internet connection.

Answer 2

Broadband internet is typically anything faster than dial-up (cable, DSL, etc.).  The most common WiFi is wireless broadband router wired to cable or DSL modem, but some devices are all purpose wireless/router/modem.

There are high speed wireless ISP's or wireless hotspots in some areas that use WiFi frequencies.  Or if you really want wireless that operates over a wide area or nationally, there is mobile broadband that uses cell phone frequencies and requires a data plan from a cell phone company.

as written on Wikipedia

Wi-Fi (IPA: /ˈwaɪfaɪ/) is the trade name for the popular wireless technology used in home networks, mobile phones, video games and more, in particular it covers the various IEEE 802.11 technoloies (including 802.11b, 802.11g, and 802.11a).

Wi-Fi technologies are supported by nearly every modern personal computer operating system and most advanced game consoles, printers, and other peripherals.

The term broadband can have different meanings in different contexts.

Broadband in telecommunications refers to a signaling method that includes or handles a relatively wide range of frequencies, which may be divided into channels or frequency bins. Broadband is always a relative term, understood according to its context. The wider the bandwidth, the greater the information-carrying capacity. In radio, for example, a very narrow-band signal will carry Morse code; a broader band will carry speech; a still broader band is required to carry music without losing the high audio frequencies required for realistic sound reproduction. A television antenna described as "normal" may be capable of receiving a certain range of channels; one described as "broadband" will receive more channels. In data communications a modem will transmit a bandwidth of 56 kilobits per seconds (kbit/s) over a telephone line; over the same telephone line a bandwidth of several megabits per second can be handled by ADSL, which is described as broadband (relative to a modem over a telephone line, although much less than can be achieved over a fiber optic circuit, for example).

Broadband in data communications can refer to broadband networks or broadband Internet and may have the same meaning as above, so that data transmission over a fiber optic cable would be referred to as broadband as compared to a telephone modem operating at 56,000 bits per second.

However, broadband in data communications is frequently used in a more technical sense to refer to data transmission where multiple pieces of data are sent simultaneously to increase the effective rate of transmission, regardless of actual data rate. In network engineering this term is used for methods where two or more signals share a medium.

Broadband in analog video distribution is traditionally used to refer to systems such as cable television, where the individual channels are modulated on carriers at fixed frequencies.[3] In this context, baseband is the term's antonym, referring to a single channel of analog video, typically in composite form with an audio subcarrier.[4] The act of demodulating converts broadband video to baseband video.

However, broadband video in the context of streaming Internet video has come to mean video files that have bitrates high enough to require broadband Internet access in order to view them.

Broadband video is also sometimes used to describe IPTV Video on demand.

The various forms of Digital Subscriber Line (DSL) services are broadband in the sense that digital information is sent over a high-bandwidth channel above the baseband voice channel on a single pair of wires.

A baseband transmission sends one type of signal using a medium's full bandwidth, as in 100BASE-T Ethernet. Ethernet, however, is the common interface to broadband modems such as DSL data links, and has a high data rate itself, so is sometimes referred to as broadband. Ethernet provisioned over cable modem is a common alternative to DSL.

Thank you for your question, I have to read also and now I know more about this topic. Al was taken from WikipediA

Answer 4

WiFi is a wireless technology used for networking. Broadband is any high speed internet access.

Edit: High speed as defined by the FCC is anything over 768 kbps.

Answer 5

yeah. and Wifi is wireless, while braodband needs to be connected. broadband can be wireless too, by using a router.
