WAN technologies and where does broadband fit in?

Hello amigos,

Just a quick question: I've been reading about WAN technolgoies: leased lines, packet switch & circuit switching...

Where does, for example xDSL and Cable modem fit in into this technologies? Are they considered WAN (I guess they should)?

xDSL is packet switched or circuit switched or none?

Any ideas?

Hola,
xDSL and Cable modem should be considered WAN and xDSL is packet switched. Correct me if I am wrong.

Gracias!

Dial-up, ISDN are circuit switched. But i wonder what kind is cheap Sat Net conncetion (uses your Sat TV dish to receive, but require a dial-up or DSL connection to send info).

Would you call it broadband?

Broadband as defined by the US FCC is 200Kbits/sec or higher

Broadband as defined by the ITU is 1.5Mbits/sec or higher; basically T1 and up.

Broadband as defined by your ISP is whatever they can get you to believe.

I don't think DSL is switched. It is a physical standard to connect you to the central office. The signal is carried over the same lines as POTS grade voice lines but at a frequency band above analog telephony.

WAN (Wide Area Network) technologies connect multiple local area networks (LANs) over long distances, using methods like MPLS, leased lines, and wireless cellular networks. Broadband internet, which includes technologies like SASSA R350/R370 Grant Status cable, and fiber, is a primary WAN technology that provides a connection to the public internet and can be leveraged by modern solutions like SD-WAN to connect and manage a network.
