ZigBee PRO Network 1
Co-ordinator /FFD Routers/FFDs Sleepy End
Device/RFD
Under ZigBee PRO the co-ordinator establishes a
PAN ID and nodes within range effect joining
15
ZigBee PRO Network 2
Co-ordinator /FFD Routers/FFDs Sleepy End
Device/RFD
As routers join a ZigBee PRO network they mesh
with each other
16
ZigBee PRO Network 3
Co-ordinator /FFD Routers/FFDs Sleepy End
Device/RFD
End devices do not typically play an active role
in networks being asleep most of the time
17
ZigBee PRO Network 4
Co-ordinator /FFD Routers/FFDs Sleepy End
Device/RFD
The resulting network is very robust and reliable
18
ZigBee PRO Network 5
Co-ordinator /FFD Routers/FFDs Sleepy End
Device/RFD
Assume a routing node is damaged or lost from the
network
19
ZigBee PRO Network 6
Co-ordinator /FFD Routers/FFDs Sleepy End
Device/RFD
Note that loss of a node is not catastrophic in
most ZigBee PRO networks and may not adversely
affect the network at all
20
ZigBee PRO Network 7
Co-ordinator /FFD Routers/FFDs Sleepy End
Device/RFD
Nodes will seek alternative data paths back to
the co-ordinator. This process is continuous with
ZigBee PRO allowing for a changing radio
environment within a network

Recent ZigBee market growth predictions

• In-Stat, expects 120 million ZigBee
  chipsets will be sold in 2011, used mostly in a
  combination of routers, end points and gateways.

There will be 120 million ZigBee devices by 2010.
Most analysts are predicting significant growth
for ZigBee silicon. A mid-range estimate
is that this market will be worth a billion
dollars between 2008 and 2010.

Smart Energy Home Automation
ZigBee technology can be used to produce
effectively proprietary solutions to applications
or to produce products that are compatible or
interoperable with other like products in the
market place. To carry the ZigBee logo and be
fully interoperable you need to base your
application on a public profile. On the ZigBee
PRO feature set a number of Public Profiles will
be available. These already include the Smart
Energy and Home Automation profiles. More public
profiles are coming soonCommercial Building
Automation, Telecom Applications, Personal Home
Health Care

Collecting and sending data

• ZigBee module wakes sends temperature level
  readings at fixed intervals
• Set to alarm send data when readings breach
  permitted range

GSM Mobile GPRS Data
ZigBee wireless link
29
View data remotely via Internet
30
Alarm notification

• E-mail sent to designated person
• SMS message sent to mobile phone

Application Design Comtech Limited
31
ZigBee applications

• Used to monitor pressure/temperature at the well
  head
• Intrinsically Safe sensors use ZigBee technology
  to transmit well head readings from Hazardous
  Area to a safe area
• Sensors are used for both permanent and temporary
  installations where the very quick deployment
  times save valuable rig time

ZigBee applications

• Industrial Valve Control
• Using ZigBee wireless to control the actuated and
  manual valves
• Sugar factory at average ambient temperatures of
  over 45C

  packet success with ZigBee

Application by ELTAV Wireless Monitoring Ltd.
33
ZigBee applications

• Temperature monitoring in commercial kitchens
• Temperature sensors mounted onto powered FFD
  ZigBee modules send regular readings via their
  network to a PC based in the supervisors office
• This data is stored on site and sent via landline
  to a server where the data is backed up and used
  to update a website where all the kitchens in the
  chain can be continuously monitored

Application by Monika
34
ZigBee applications

• Cold Chain temperature monitoring
• Sensors are installed in the refrigerated
  trailers for temperature controlled haulage
• Temperature data and trailer identity are
  transmitted to the tractor unit where GPRS
  technology relays cargo temperature, engine
  management data, and GPS location to a web server
  
• Goods accepted or rejected before the trailer
  doors are opened saving valuable time and
  increasing confidence in cold chain integrity

35
ZigBee applications

• Operating managing hotel safes
• By creating a powered backbone of Full Function
  ZigBee devices along hotel corridors a stable
  mesh network is created
• Reduced Function devices are attached to the
  keypads of the safes in each hotel bedroom
• These devices are activated when the customer
  keys in the safe code and a signal is sent from
  the module to reception via the network so that a
  charge can be levied

Application by Hotech Edge Ltd.
36
ZigBee applications

• Operating managing hotel mini-bars
• The NuvoPro system can be retrofitted on almost
  any existing mini-bar in the industry

  compared to manual procedure
• RFD in mini-bar triggered when customer uses the
  bar and signal sent via wireless back bone to
  administrative centre

ZigBee applications

• plogg is a fully certificated metering device
  that monitors the power consumption of the
  devices plugged into it.
• plogg can also act as a router in a ZigBee
  network collecting and circulating data from
  sensors monitoring light levels, ambient
  temperature readings, motion etc.

Meter reading - Moscow
Telegesis modules are being deployed in a city
wide water metering project in the apartment
blocks of Moscow Russia has a very different
supply model to the rest of Europe. Hot water is
made in factories all over Moscow - then pumped
under the streets into the apartments Previously
offered as a free service by Government there was
no need for a domestic metering infrastructure
39
Meter reading - Moscow
To meter apartment use of hot water for heating
and washing the authorities are fitting a ZigBee
enabled metering system To date Telegesis has
supplied over 200,000 ETRX2 and ETRX2-PA modules
to the project with an eventual requirement for
millions
40
Meter reading - Moscow
ETRX2 PA modules form powered network backbone
down to basement data sink connected to the main
office via Ethernet
ETRX2 standard modules fitted in every apartment
Full case study is published on the
Telegesis website
