Describe the most popular wireless Internet access technologies today. Compare and contrast them.

Solutions is:

There are two popular wireless Internet access technologies today. They are Wifi and 3G,4G. Descriptions are below:

a) Wifi (802.11) 
In a wireless LAN, wireless users transmit/receive packets to/from a base station (i.e., wireless access point) within a radius of few tens of meters. The base station is typically connected to the wired Internet and thus serves to connect wireless users to the wired network.


b) 3G and 4G wide-area wireless access networks:
 In these systems, packets are transmitted over the same wireless infrastructure used for cellular telephony, with the base station thus being managed by a telecommunications provider. This provides wireless access to users within a radius of tens of kilometers of the base station.
