Understanding Internet protocols

I need to know about 802.11 a, b, g, and n.

1. are any troubled with interference form devices such as cell phones, etc?

2. which is fastest, Is that one the most practical for a home net work or do problems arise with it?

3, is the hardware for one standard more expensive than the others?

Please help, I need to know this tonight!

Been here? www.google.com    Good place for homework related questions.

1) read here > http://www.juniper.net/techpubs/en_US/junos-space-apps12.3/network-director/topics/concept/wireless-interference.html - also read up on attenuation.

2)the 'n' standard is fastest out of your list. Being the fastest makes it the obvious choice for a household. Problems as with any wireless tech is anything that will be a disrupt the connection - solid walls, high emr devices etc.

3)most devices cover all standards anyway except for rising uptake of the newer, faster ac standard.

this is where i learned networking 

People hate on Wikipedia a lot but 99% of the stuff I have learned on Wikipedia has been 100% true, especially in the area of networking. It's amazing what you can learn just by messing around with some virtual machines on a little laptop.

 

Hey I'm just curious, what is "Super G"? Is that an actual thing? I saw it as a settings option while helping a friend configure an EXTREMELY old router (about 4 years old)

In your list N is fastest.

The only thing that has reported a slight interference with WIFI is home microwaves.

Currently the price for all these are relatively similar with AC (newer than N) being the most expensive.

Any other questions?
