Limitless™ Multi-Protocol Receiver, WMPR Series

Intended Audience

This guide is intended for people who are responsible for plan­ning, configuring, administering, and operating the Limitless™
Network.

Prerequisite Skills

It is assumed that you are familiar with the operation of Limit­less™ Networks.

About this Document

This document outlines professional installation requirements
for the Limitless™ Receiver, WMPR Series. Professional instal­lation is required to comply with certification agency and legal
requirements. This document must be adhered to for all instal­lations of the Limitless™ Receiver, WMPR Series.

These devices are not intended for critical control where there
is a single point of failure or where single points of failure result
in unsafe conditions. As with any process control solution, it
is the end users’ responsibility to weigh the risks and benefits
to determine if the products used are the right match for the
application based on security, safety, regulations, and perfor­mance.

References

The following list identifies all documents that may be sources
of reference for material discussed in this publication.

1 | PRODUCT DESCRIPTION

1.1 | General

The Limitless™ Series uses the latest commercial off-the­shelf wireless technology that can be used in a wide variety
of applications. This is especially beneficial for remote
monitoring applications where previous wiring installation or
wire maintenance was not physically possible or economically
feasible. This document will provide installation instructions to
properly install a Limitless™ Wireless MultiProtocol Receiver
WMPR, as well as a detailed understanding of its functions.

1.2 | Principle of Operation

A Limitless™ input sends an RF signal to the WMPR when
the Limitless™ digital or analog input changes state. There
may be up to 14 Limitless™ digital or analog inputs that
communicate and indicate their state to a single WMPR. The
WMPR receiver is menu driven through the use of function
buttons and a easy to read LCD display. The menu allows you to
see status of the nodes, configure nodes, and update receiver
functionality. A change of state of a Limitless ™ input will cause
a corresponding change in output of the particular node to be
output via an EtherNet/IP™ output. The WMPR indicates low
battery conditions, lost RF links, as well as other diagnostic and
functional operations described in further detail throughout
this manual.

4 | R.F. INTERFERENCE
CONSIDERATIONS

4.1 | R.F. Interference Considerations

4.1.1 | General

The 802.15.4 specification provides a high resistance to inter­ference. Within the 2.4 GHz band, there are 16 channels, each
using approximately 2 MHz of bandwidth. The channel used
may be rapidly changed depending on the presence of other
signals sensed in that channel. Thus narrow band interfering
signals may have no effect, while broadband noise sources may
cause loss. The effect of light to moderate interference is not to
make the system fail, but to increase the rate of “lost packets” of
data. These “lost packets” are simply retransmitted as needed,
so the user may not notice any problem. More serious interfer­ence can cause loss of more data updates, and error messages
reported by the WMPR, as well as shorter battery life.

4.1.2 | WiFi Networks

Most WiFi (WLAN) networks operate in the same 2.4 GHz range
and use wider bands within that range. Also, the faster proto­cols (802.11N or AC), may utilize multiple channels. Factors af­fecting R.F. interference would be channel separation, distance
separation, and duty cycle.

• Channel separation: Studies have shown that a channel
separation of 7 MHz will make interference less likely. WiFi
routers can be set to use different channels as needed, and
auto channel modes can be disabled. If possible, switch­ing to a 5 GHz-only protocol (using 802.11N or AC), would
eliminate any possibility of 2.4 GHz interference.

• Distance separation: A physical separation of 10 meters or
more will reduce possibility of interference.

• Duty Cycle: Generally the duty cycle of WiFi routers is very
low for simple uses as e-mailing, messaging, most web
browsing, and voice protocols. However, a video camera or
multiple users streaming video would cause a significant
increase in bandwidth usage and increase the possibility of
interference, making channel or distance separation more
desirable.

Regarding the WiFi client (laptop, smartphone, tablet), they are
much less of a problem as they generally operate with a much
reduced duty cycle (most data is received by the device), and
may operate with much lower transmit power

different. However, if a suspected interference source causes a
large reduction in consumer WiFi download speed, it is likely it
could also cause interference to the 802.15.4 data used by the
WMPR.

4.1.4 | Bluetooth® Devices

Bluetooth® interference is less of an issue, due to the very
narrow bandwidth of Bluetooth® signals, the low transmit
power, and the rapid “frequency hopping” of the signals. If the

802.15.4 device misses a packet of data due to a Bluetooth®
burst of data, the re-transmission of the 802.15.4 data will
likely succeed, as the Bluetooth® will have hopped to a different
channel by then.

4.1.5 | Wireless Video Camera and Video Links

Wireless video links operating in the 2.4 GHz band can cause
serious interference as they are operating continuously, use a
wide (6 MHz) bandwidth), and may be more powerful. Interfer­ence from wireless video could cause the “NO RF” indication in
severe cases. As mentioned, frequency and/or distance separa­tion may be required.

• Frequency Separation: Many video links have four or more

• Distance Separation: Separating the video link sensor from

4.1.6 | Microwave Ovens

Microwave ovens operate in the 2.4 GHz range, they are power­ful, and a high-duty cycle. However, they may not be a problem
to a modern 802.15.4 network. The magnetron in a microwave
oven is driven by half-wave rectified AC, so the R.F. output is
actually off for one half of the 60 Hz or 50 Hz power line cycle
(8.33 msec or 10.0 msec). During that part of the cycle, the
packets of 802.15.4 data may succeed. However, close to half
of the packets may require retransmission, so data throughput
could be greatly reduced.

channels selectable. Changing channels may help. Addi­tionally, wireless video links are available in the 900 MHz
band, and the 1.2 GHz band. Switching to one of those
would eliminate interference issues with 802.15.4 (and

802.11x).

the WMPR would be very desirable. Alternatively, utilizing
directional antennas on the WMPR, and /or on the wireless
video link would help greatly.

4.1.3 | Smart Phone “Apps”

Smart phone “apps” are available to display consumer WiFi
signal strengths or download/upload speeds. These apps
will not display the 802.15.4 signals as the packet format is

4.1.7 | Cordless Phones/Baby Monitors/
Intercoms

A 2.4 GHz cordless phone in very close proximity to a wireless
sensor could cause lost packets, while the phone is in use, but
is not a very likely cause. If suspected interference, a simple
remedy is to switch to a DECT 6.0 cordless phone operating on

1.9 GHz.
