In traffic zones (like city's arterial roads, express ways), wider coverage is expected with low to high mobility.
Connection/capacity densities and mobility may be estimated well in this field case.
Characteristics of this field case is concentrated set of users and moving at low to high speeds.
Similar to traffic zone case, connection/capacity densities and mobility may be estimated well.
The characteristic of moving concentrated set of users (indoors) may be exploited if we have concept of "moving (micro) cells".
Maintaining connectivity and the data speed at certain level over cell edge and during transition to next cell is field requirement for 5G.
Traditionally, data speeds are lower at cell edge and there is interruption time associated with transition.
Number of users are ever increasing in urban areas.
More areas are being urbanised.
Also, as in the past, there is increasing flow towards cities.
This has resulted in ever increasing connection/capacity densities and wider population areas.
Scalable, energy efficient and cost effective networks are expected from 5G.
In conclusion
Deployments, selection of carrier frequencies, and RF technologies shall play a major role in 5G.
Requirement on 5G is to have RF technologies and protocols that could exploit field characteristics (to achieve requirements coming from user trends).
Machines are relatively new entrants in 3GPP world.
Let us look at the requirements that it brings.
M2M stand for Machine to machine and IoT stand for Internet of Things.
An example of M2M is communication of sensed parameter values from sensor to central (automation) server in industrial environment.
IoT introduced remote machine communication over IP.
An example of IoT could be power meter updating its reading on monthly basis to central billing server of power company.
There are multitude of devices that could be connected wirelessly soon (or are already connected under IoT):
Industrial equipment’s/devices/sensors (already coming under M2M), devices from fields like Surveillance, Power transmission, Traffic control, Railways,
Ambient screens (used for various purposes like advertisements, public announcements etc.),
Medical/Healthcare monitoring devices,
Consumer appliances (aka Smart appliances) like refrigerator and so on.
