Internet Types: Cable, Satellite & WiMax
Cable, Satellite & WiMAX
Now we move away from telephone lines to faster transmission tools such as cable, satellite and WiMAXs.
Cable connectivity is actually performed by a cable modems which is more a transceiver that a modulator. It converts its signal from analog to digital which is how we receive movies, and is faster but is also restricted by geography.
Satellite is one alternative when cable-based connectivity is not possible. We’ll diagram that transmission path with is basically an installed dish at the client location pointed at the satellite dish in space which belongs to host ISP. It’s a one-to-one directional relationship, so the client must have line-of-site to the satellite for internet connectivity.
You’ll learn what a response ping time is, what the transmission variations are between download and upload services, and what latency is and why it plus bandwidth determines the degree of connectivity transmission speeds.
In WiMAX, you also have point A-to-point B line-of-sight requirements, but it’s a single station delivering wireless connectivity to multiple devices that are widely dispersed, over long distances at fast transmission speed and using the 802.16e standard.
