6. 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)
