un-controlled sources of interference and hence inherently cannot provide guaranteed reliability; however,
higher levels of reliability is achievable with implementing efficient medium access mechanisms and operation
in low interference environment.

• Determinism
Mission critical applications require determinism to be provided by the access technologies. While unlicensed
technologies in general do not provide guaranteed timely access to the wireless medium, in special scenarios,
for example in an isolated industrial field, determinism can be achieved especially for short-range and high-
bandwidth communication technologies like WiGig.

• Cost
Unlicensed communication technologies enjoy lower cost in general compared to cellular communications.
Among unlicensed technologies the cost the complexity of the technology and the size of the existing
ecosystem impacts the cost.
• Security

Secure communication is required for many IOT applications and becomes more critical for longer range
access technologies.
