To access 3G you must have a 3G capable device and a data plan

3G is not too bad price wise, but overages can cost thousands

Can be used to access internet, make calls (video and voice), and download/upload data.

4G CONNECTIONS• The Newest mobile

connection available to the public

• Can reach speeds of 100mbps download and 50mbps upload (under ideal circumstances)

• 4G works by using orthogonal frequency-division multiplexing or OFDM

• OFDM: Signal is divided in to parallel data streams and then brought back together once it reaches your device

• Under real world conditions, testers got 6mbps download on 4G and 1mbps on 3g

• 4g isn’t available everywhere (see next slide)
