As a practical matter, standards bodies are aiming for fifth generation mobile networks providing guaranteeing 50 Mbps per device. That might have business model implications for smartphone users in a stationary location, where most consumer applications, including video, can be supported.
In “shared” settings, such as automobiles, per-user bandwidth might be reduced, if devices rely on the vehicle’s acces. If each connected device uses its own account, there might be much impact at all.
Standards bodies also are aiming for the ability to sustain connections when receiver are moving
on the ground at 500 kilometers per hour, supporting virtually all vehicular or rail system access applications, according to Adlane Fellah, WiFi360 managing director.
The 5G standards also will support venue access with support for at least 0.75 Tb of traffic in a geographic area the size of a stadium.
5G networks also will support one million or more devices per square kilometer. At such densities 5G would rival either Wi-Fi or ZigBee connectivity choices, in terms of capacity.
Network availability could be “five nines” or even more stringent (up to seven nines, perhaps).
End-to-end latency of perhaps 5 ms or less also is among the design goals.
5G networks also will support device-to-device communications, an advantage when mobile network transmitting sites actually go offline.
As always, cost will be an issue, enabling or limiting the range of use cases for the 5G network, compared to fixed networks. But 5G will be the first mobile network to have a plausible chance of substituting fully for the fixed network.
