1. Overview
The A110LR09A and A110LR09C are surface mount modules –each with an integrated crystal,
internal voltage regulator, matching circuitry and filtering. The A110LR09A has an integral
antenna, whereas the A110LR09C utilizes an external antenna through a U.FL connector (see
Table 1). The modules operate in the European 868 –870MHz and US 902 –928MHz ISM
bands and are ideal for achieving low power wireless connectivity without having to deal with
extensive RF, antenna design and regulatory compliance, allowing quick time to market. The
modules are 100% tested to provide consistent performance.
The A110LR09A and A110LR09C have received regulatory approvals for modular devices in
Europe and in the US. The modular approval allows the OEM or end user to place either an
A110LR09A or an A110LR09C with an approved antenna inside a finished product without
having to perform costly regulatory testing for an intentional radiator. Section 2 has information
on the requirements for the end user/integrator must fulfill to use the modules without intentional
radiator regulatory testing. The receiver section of the modules has been evaluated and
approved as Category II receiver for use in Europe.
The A110LR09A and A110LR09C are based on the CC110L transceiver IC from Texas
Instruments. All control lines for the transceiver are provided at module level for full control of its
operation. Please see the CC110L data sheet (www.ti.com) for how to control the modules.
Please see section 2.5 for the recommended register settings to achieve optimal performance
and regulatory compliance.
The A110LR09A measure 9x16x2.5mm and A110LR09C measures 9x12x2.5mm. The modules
are footprint compatible with each other.
1.1. A110LR09A
The A110LR09A has an integral antenna, providing high efficiency and near omni-directional
radiation pattern. This approach offers the lowest system cost when the application allows
collocation of radio and antenna.
1.2. A110LR09C
The A110LR09C has a compact antenna connector that allows for locating the antenna away
from the module due to form/function or in order to exit a metal enclosure, see figure 6 –9 for
more information on antenna location and enclosure considerations.

1.4. Theory of Operation
The A110LR09A and A110LR09C are for low power wireless applications in the European 868
–870MHz, and US 902 –928MHz ISM band. The devices can be used to implement a variety
of networks, including; point to point, point to multipoint, peer to peer and mesh networks.
The A110LR09A and A110LR09C both interface to an application microcontroller via an SPI
bus. Physical and MAC layer functionality are accessed via the SPI bus through addressable
registers as well as execution commands. Data received, or to be transmitted, are also

A110LR09x –User’s Manual Page 7 of 38
Release Date 10/31/11
accessed through the SPI bus and are implemented as a FIFO register (64 bytes each for Tx
and Rx).
To transmit, a frame of data is placed in the FIFO; this may include a destination address. A
transmit command is given, which will transmit the data according to the initial setup of the
registers. To receive data, a receive command is given, which enables the unit to “listen”for a
transmission; when such a transmission occurs, it places the received frame in the FIFO. When
neither transmit nor receive is required, the device can enter either an Idle mode, from which it
can quickly re-enter a receive/transmit mode, or a low power sleep mode from which a crystal
startup is required prior to transmit or receive operation.
Below is a block diagram for each of the A110LR09A and A110LR09C modules.
Antenna
oThe antenna couples energy between the air and the AIR module. For
applications where installations are done by an end user (non-professional), an
omni-directional antenna pattern is desired such that the application will work
equally well in every direction. Similarly for peer to peer or point to multipoint
applications, an omni-directional pattern is desired such that all nodes have a fair
chance of communicating. The A110LR09A module has an integral antenna that
is near omni-directional, whereas the A110LR09C has approved antenna options
ranging from near omni-directional to shaped front/back patterns (useful for
inline, professional installations). Note that the end radiation pattern depends not
only on the antenna, but also on the ground plane, enclosure and installation
environment.
Filtering
oFiltering removes spurious signals to comply with regulatory intentional radiator
requirements.
Matching
oMatching provides the correct loading of the transmit amplifier to achieve the
highest output power, as well as the correct loading for the receive LNA to
achieve the best sensitivity.
Physical
oThe physical layer provides conversions between data, symbol and RF signal.
MAC
oThe MAC layer is part of the Logical Link Layer and provides frame handling,
addressing and medium access services. For CE operations, part of the MAC is
implemented in the S/W.
Microcontroller Interface
oThe microcontroller interface exposes registers and commands for the physical
and MAC layers to a microcontroller.
Power Management
oPower management ensures a stable supply for the internal functions, as well as
providing means for a low power sleep mode (in which case, most of the
transceiver is power off).

Figure 3 Transceiver IC block diagram.
1.4.1. Typical Flow
After initial setup of registers for desired behavior, the normal operation flow diagram is shown
in Figure 4. In applications of infrequent data transmissions, the transceiver would be in “sleep”
mode to save power (400nA). From there it would wake up and then enter “idle” mode. As part
of the wake up process the crystal oscillator is started (~240μs) and the digital microcontroller
interface is powered up. Before transmit or receive, the frequency synthesizer needs to be
started (“FS_Wakeup”) and, having been powered off (or idle for a while), the control loop of the
VCO/PLL needs to be calibrated (“calibrate”).
A data frame is loaded into the transmit FIFO and the “TX” mode is entered. The transceiver will
transmit the data and enter “idle” mode after completion. When transmit is complete “RX” mode
is entered to wait for the acknowledge frame. Once a frame is received, the transceiver will
again enter “idle” mode. If no acknowledge frame is received within a given timeout, the data
frame would be re-transmitted. If the acknowledge frame indicates that the data was received,
the next data frame will be transmitted. After the last data frame has been transmitted
successfully, the transceiver will again be put in “sleep” mode.

Alarm systems
oThese typically use low duty cycles and are therefore easy to avoid using
acknowledge/retransmit methods
Car alarms (internal motion sensors)
Video surveillance
oThese are typically operated on a fixed channel determined at installation time
and can be avoided by using clear channel assessment. It may be useful to
change the channel used by the video surveillance equipment also, if possible.
2.4.1. Time critical data
If the user requires specific time critical data throughput that cannot tolerate the delays of
potentially many re-transmissions, the user is encouraged to implement an environment-aware
algorithm that periodically monitors/scans the frequency band and maintain a list of “best
available” channels.
2.5. Approved Usage
These radio modules can be used in a variety of physical layer configurations; the following
restricts the use to maintain compliance with the above referenced certification bodies.
The user is encouraged to use minimum power required to establish a link, thus minimizing
interference.
Changes or modifications to the module and/or operation outside the limits set forth below are
prohibited and could void the user’s authority to operate the modules.
Uses of these radio modules are limited to the specific register settings that are optimized for
performance and compliance. Register setting files are provided online at www.anaren.com.

The operating frequency must be selected in such a way that the complete modulated signal
stays within the band of 902 - 928MHz. The modules can be operated at any frequency
between the lowest and highest frequencies in the band. The lowest and highest frequencies
are given as follow:
Lowest Frequency: 902.7MHz
Highest Frequency: 927.377MHz

Within the European 868-870 MHz ISM band, there are several sub-bands with different
requirements. A summary of these bands is given in Table 5. Considering the modulation
bandwidth of each modulation type, frequency drift of the module in the extreme working
conditions, and the channel spacing for each configuration, usable channels for each
modulation is obtained for the sub-bands. Table 6 lists the approved configurations and
applicable channels for each sub-band. Table 7 shows list of available channels along with the
corresponding frequencies and register settings.
