Transceiver OL2381 using wireless M-BUS
1. Introduction
This application note describes how to use the NXP transceiver OL2381 in a wireless
M-Bus application.
Wireless M-Bus is a European standard
Ref. 5
for the transmission of data from utility
meters such as gas, heat and water. Its primary use is in the Short Range Devices (SRD)
unlicensed telemetry band at 868 MHz. As a broad definition, this standard can be applied
to various applications.
This application note only describes the physical layer.
The OL2381 is a highly integrated and fully software configurable, single-chip transceiver
operating in ISM/SRD band. The OL2381 has a small form factor, low power
consumption, and a wide supply voltage range. These features make it suitable for use in
battery powered handheld devices and their counterparts.
OL2381 value propositions for wireless M-Bus are:
Full wireless M-Bus compliance (except N-mode)
Efficient RF power amplifier with programmable power output
Highly sensitive receiver with programmable gain
Programmable data rate
Programmable center frequency; on-the-fly and multi-channel operation
Intelligent state machine reduces microcontroller load and power consumption
Several automatic signal monitors allow long system battery life
–
wake-up search timer
–
RSSI level checker
–
coding checker
–
baud rate checker
–
preamble detection
Programmable IF filter for different bandwidth requirements:
–
narrowband for long range with low data rate
–
wideband for short range with high data rate
This application note focuses on the 868 MHz application, however, the 433 MHz
(F-Mode) frequency is also supported (refer to draft version of
Ref. 3
).
For a specific wireless M-BUS solution, refer to
Ref. 6
which provides a complete energy
metering solution with software, hardware and data sheets. The internet solution uses a
3-wire SPI interface, whereas this document describes the 7-wire interface.
