tablet, or computer. Product installation codes are used to ensure only authorized
devices can join the network. The simple protocols for forming and joining networks
allow systems to self-configure and fix routing problems as they occur.
●
Secure
: Devices do not join the network unless authorized and all communications
are encrypted and secure. Security is provided at the network layer and can be at
the application layer. All Thread networks are encrypted using a smartphone-era
authenticationscheme and Advanced Encryption Standard (AES) encryption. The
security used in Thread networks is stronger than other wireless standards the
Thread Group has evaluated.
●
Small and large networks
: Home networks vary from several to hundreds of
devices. The networking layer is designed to optimize the network operation based
on the expected use.
●
Range
: Typical devices provide sufficient range to cover a normal home. Readily
available designs with power amplifiers extend the range substantially. A
distributed spread spectrum is used at the Physical Layer (PHY) to be more
immune to interference.
●
No single point of failure
: The Thread stack is designed to provide secure and
reliable operations even with the failure or loss of individual devices.
●
Low power
: Devices efficiently communicate to deliver an enhanced user
experience with years of expected life under normal battery conditions. Devices
can typically operate for several years on AA type batteries using suitable duty
cycles.
●
Cost-effective
: Compatible chipsets and software stacks from multiple vendors
are priced for mass deployment, and designed from the ground up to have
extremely low-power consumption. Typical home products run in the connected
home include: normally powered (lighting, appliances, HVAC, fans), powered or
battery-operated (thermostats, smoke detectors, CO and CO
2
detectors, security
systems), and normally battery-operated (door sensors, window sensors, motion
sensors, door locks).
