Part 1

Compare and contrast at least five technologies that are readily available for in-home internet access. You should consider practical as well as technical differences in your comparison. Do not include Frame Relay or ATM as these are primarily larger scale business solutions.

802.11N

Higher-speed standards up to 300+ Mbps

802.11n uses (MIMO) technology and a wider radio frequency channel

It provides a mechanism called frame aggregation to decrease time between transmissions

Channels operating at 40 MHz are another feature incorporated into 802.11n

The transmitter and receiver use pre-coding & post-coding techniques  to achieve the capacity of a MIMO link
