900 MHz ISM BandMulti-hop

Wireless System

Factories, hospitals, schools, and many other entities throughout the United States have utility facilities that are in operation at all times. Such utility facilities include power, gas, boiler, and compressor equipment as well as pumping equipment for groundwater and wastewater treatment equipment. They play important roles in most sites. Nevertheless, many of them are maintained in conventional “manual” methods because they have not been considered as a subject for centralized monitoring.

M-System has released the WL40F Series 900 MHz Band Multi-hop Wireless System as a means to easily and inexpensively realize centralized monitoring of utility facilities . The FCC Part 15 compliant low-electric-power wireless devices require no licence for use in the United States.

Furthermore, for the effective use of the WL40F Series, M-System offers the DL8 Web Data Logger and the TR30-G Tablet Recorder , which can be connected direct to the Internet, as well as the DL30 Web Data Logger , which can be installed onsite for use with ease.

M-System has summarized application examples of these radio applications so that everyone in charge of facility maintenance may use them. These are a few examples of installations that M-System has delivered using the above products.

Recommendation for Wireless Monitoring of Utility Facilities Con�guration Example of M-System’s Wireless System

Introduction

1 Short installation work period

PCs with browser software can be used.

Wireless I/O

The user can collect monitoring data of a factory's utility facilities from remote locations such as the headquarters and

branch offices. The system can send e-mails to report abnormal or failures to

the user's smartphone.

Each child station takes in signals according to the commands from the master unit

and transmits data to the parent station.

I can monitor the status of utility facilities in my office.

Modbus-RTU

Modbus/TCP Master UnitsThe master unit transmits cyclic commands to the slave units

through the WL40F Series parent station and collects responses from slave units.

ISP

Router

Use another child station as a repeater if the communications distance

is long or if there is an obstacle.

Just install one Child unit in the desired place.

It’s also easy to change the location

afterwards.

Wireless system cost is much lower simply

because there is no signal line wiring.

The use of wireless communication equipment requires approval on a country-by-country basis. The WL40F Series products are usable only in the US. The use of wireless communication equipment requires approval on a country-by-country basis. The WL40F Series products are usable only in the US.

No opening in schedule for wiring work.

A wireless system needs no pit digging or

cable laying work, realizing a drastically shortened

installation period with a simple work plan.

The parent station transmits

commands from the Modbus master unit to the slave station and responds

from the slaves to the master.

Terminology in this Brochure: “Parent” and “Child” mean “Wireless Master” and “Wireless Slave” stations respectively, whereas “Master” and “Slave” mean “Modbus Master” and “Modbus Slave”.

The WL40F Series 900 MHz Band Multi-hop Wireless

System needs no radio license, no license application fee, and no

monthly communications charge.

We want to add more monitoring

points but work costs are surprisingly

high.

Introduction of 900 MHz band wireless products

900 MHz ISM Band Multi-hop Wireless System

What is 900 MHz band wireless communication?

What is multi-hop technology?

Communications path

Modbus/TCP Modbus/TCP

Automatically switched to an alternative path

An initial power level of 20 mW will be attenuated more and more as a result of path loss over a large area.

With consideration of the propagation environment,

the rated maximum inter-station transmission distance is set to 0.62 miles (1 km).

According to the graph of Distance vs. Reception Level on the right-hand side,

the communications distance should be several thousand meters at a level of -85 dBm.

However, this is a theoretical value.

As shown in table 1, the rated reception sensitivity limit of

the WL40F Series is -90 dBm.

With a margin of three times taken into

account, the practical reception sensitivity limit is considered

to -85 dBm.

Reference: A level of -90 dBm is equivalent to 1 pW based on a level of 0 dBm as 1 mW.

The WL40F Series Wireless I/O System employs a licence-free 900 MHz ISM band module. Compared with 2.4 GHz band and 5 GHz band wireless LANs and wireless networks for instrumentation that use higher frequency bands, the 900 MHz band ensures stable communication quality and a long communications distance. It does not require license registration, and unlike mobile communications, users do not need to pay telecommunications charges to telecommunications service provider. Therefore, the 900 MHz band is ideal in terms of operating cost as well.

Multi-hop wireless communication is a wireless network conveying data through a number of wireless communication devices in a “bucket-brigade” manner.Relaying paths are automatically switched to an alternative one when one section of the connection is weak.In the WL40F Series, up to 100 child stations connect to asingle parent station. The communications distance between stations can be up to 0.62 miles (1 km), thus making it possible to construct a wireless network in a wide range.
