SENSING RANGE & ROBUSTNESS

2. Typical distance transmitter / receiver
100m in free field*
Here we will see why and when to use an antenna.
#First, the receiver can receive signal from transmitter around a 100 meter area in a free field!
A free field is an unobstructed area and no radio perturbation.
#But, it can happen that the transmitter is located inside a cabinet, which will absorb the signal: from 50% to 100%. #In this case, the transmitter must be moved closer to the transmitter, within an area around 25 meters.
##If the push button or transmitter cannot be closer, in this case a relay antenna can be implemented to reinforce the signal. #When the antenna is implemented, the reception area is larger, and can reach 40 meters or more, depending of the environment, when the receiver is inside a cabinet.

The performances are the same whatever the type of receiver.

5. How to ensure a reliable transmission anywhere in a workshop
By installing a set of relay antennas in a facility, the radio transmission will operate in all the area
Benefits : Reliability increased + independent from the changes of location of machines

6. Possibility to use many relay antennas for the same application
Example with 2 or many relay antennas ZBRA1
Transmission delay
Pushbutton receiver (change relay status): 20 ms maximum
Pushbutton relay antenna receiver (change relay status) : 74 ms maximum
Each relay antenna needs between 10 to 54ms to resend the message coming from the transmitter.

7. Why XB5R suitable for industrial use
ZigBee is developed by the ZigBee Alliance:
A consortium of end users and solution providers, primarily responsible for the development of the standard
Developing applications and network capability utilizing the packet delivery mechanism
Addresses application and interoperability needs of a substantial part of the market including industrial segment
Data coding system :
ZigBee relies upon the robust IEEE PHY/MAC to provide reliable data transfer in noisy, interference rich environments
32 millions of different ID numbers for each transmitter :
One receiver will not be tripped by a transmitter unless it has been taught before

8. Why XB5R suitable for industrial use
Phase Modulation :
Superior noise and interference rejection, enhanced immunity to signal fading, and reduced susceptibility to nonlinearities in the transmission and receiving systems
standard :
Channel 11 offers the lowest probability to interfere with other frequencies operating within the 2,4 GHz bandwidth

9. Compliance to industrial standards
EC marking (Transmitter -button- , Receiver and Antenna: EN 301 489-1 and EN 301 489-3)
