Zigbee Technology
ZigBee™ radios are used by Wellspring (and many others)
to communicate building control and monitored data using an
open published communications protocol. The word "ZigBee™"
actually refers to an open radio protocol documented in the
IEEE Standard 802.15.4. As such, any product that uses the
ZigBee™ protocol to communicate can send its data over
any ZigBee™ network. That's why ZigBee™ is actively
supported by 175 companies, including Motorola, Johnson Controls,
Trane, Inovonics, Mitsubishi, Honeywell, Samsung, IBM, Itron
Eaton, Invensys, Cisco, Hitachi and Texas Instruments, just
to name a few.
Why Choose ZigBee?
The Fact that ZigBee™ is an open protocol may be the
most compelling reason to choose a ZigBee™ based system
- but there are many other reasons:
Reliable Data Delivery
ZigBee™ radios form a self healing two-way mesh
network that delivers much higher data through-put reliability.
If one node fails, another picks up the load. If messages
are not acknowledged, they retry. If interference becomes
an issue, the frequency of the network can be changed.
ZigBee™ systems can run on any of 16 channels. |
Shut-Offs
Every ZigBee™ radio can receive as well send, so every
meter can accept control instructions. For example, you
can curtail utility use if the apartment is unoccupied
or if the bill is not paid. ZigBee™ gives you control
capabilities no other radio network has. |
Other Applications
ZigBee™ will lower the cost to add new ZigBee™
based systems as they become available from any supplier,
like security monitoring, smart temperature control, electric
load controls on peak, time of day electric metering,
intercom, text messaging to a display in each apartment.
The list of possibilities is exhaustive. |
Why Choose Wellspring's ZigBee™ System?
Easy Low Cost Installation
Wellspring systems self configure using routers that are
designed for easy installation inside the cabinet over
the refrigerator, or anywhere there is an existing electrical
outlet. No special radio expertise is required. |
Power Agility
Wellspring goes beyond the ZigBee™ protocol, by
allowing transmit power levels to vary between 1 milliwatt
(.001 watt) and 100mW (0.1 watt). Wellspring adds a layer
of software that allows each Wellspring radio to adjust
its power level up and down as the radio environment changes.
So as furniture moves, new interference sources pop up,
trees grow, and weather happens, transmit power is adjusted
automatically to assure that data get through. |
Long Battery Life
Wellspring uses replaceable $3 industrial alkaline batteries
that last at least seven years in our network. |
