Intelligent Buildings with wireless solutions from lighting control, to environmental monitoring, tracking, people counting and more are proliferating.
And with good reasons, reduced installation and maintenance costs being the primary driver for many with the promise of more granular data collection and control.
But not all wireless is created equal and there are untold numbers of horror stories across all types off applications where promises of wireless have never been delivered.
- NOTING THAT environmental parameters require bandwidth based on number of metrics and sampling rate,
- utilisation requires bandwidth based on spatial data points and sampling rate,
- RLTS requires bandwidth and extremely low latency.
This is a collection of the basic wireless benchmarks needed for implementing Intelligent Buildings.
It is in effect driven by four key parameters – get these four right and you are on your way – miss them and you will soon live to regret it.
1. Sensor Communication should be over a
• robust industrial mesh network using a
• low latency secure protocol such as
• OpenThread, 802.15.4, Bluetooth Mesh or Wirepas.
2. The wireless protocol should be a
• self-healing adaptive mesh for
• ad-hoc network configuration.
3. Network topologies should be
• optimised to reduce the number of signal hops and
• use a flooding technique or a
• routing technique for efficiency.
4. Communication bandwidth should
• exceed 500kbit/s to
• sustain uplink data logs and
• simultaneous downlink commands to the sensor with a
• round trip latency less than 200ms.
