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
o The 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
o Filtering removes spurious signals to comply with regulatory intentional radiator
requirements.
Matching
o Matching 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
o The physical layer provides conversions between data, symbol and RF signal.
MAC
o The 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
o The microcontroller interface exposes registers and commands for the physical
and MAC layers to a microcontroller.
Power Management
o Power 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.

2.4. Potential Interference Sources
Alarm systems
o These typically use low duty cycles and are therefore easy to avoid using
acknowledge/retransmit methods
Car alarms (internal motion sensors)
Video surveillance
o These 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.

In order to comply with the output power limitations in Europe, the maximum values given in
Table 8 below must be observed. Modulations M14, ML2 and ML3 are considered to be
wideband modulations and therefore subject to the power spectral density requirements. Lower
power levels for these configurations ensure compliance to the specifications. The limits are
given based on the maximum allowed power level in a specific band and temperature
conditions.

ML2 -2 (40) 0 (8E) 1 (8D)
ML3 -2 (40) -1 (60) 0 (8E)
2.5.2.1. Spectrum Access and Mitigation Requirements
As part of the requirements for compliance, the applications must observe the restrictions that
are listed in Table 5. Specifically, the spectrum access and mitigation requirements (e.g. Duty
Cycle or LBT+AFA) have to be met. Some sub-bands (see Table 5) allow limited Duty cycling
while some others let the user choose between limited Duty cycling and LBT+AFA
implementation. In case of LBT+AFA, AFA (Adaptive Frequency Agility) has to be implemented
in the customer’s SW stack since there is no specific hardware support for this functionality.
2.5.2.1.1. Duty Cycling
Table 5 lists all sub-bands together with the usage requirements. In this table, Duty Cycling
requirements are listed under “Restrictions” column. It applies to all transmitters excluding
those with a LBT facility with AFA (explained in the next sub-section). The Duty Cycle is defined
as the ratio, expressed as a percentage, of the maximum transmitter “ON” time monitored over
one hour, relative to a one hour period. The device may be triggered either automatically or
manually. And, depending on how the device is triggered, the duty cycle is either fixed or
random.
For automatic operated devices, either software controlled or pre-programmed devices, the
OEM integrator or end product developer shall declare the duty cycle class or classes in the
end-product user manual or user guide. For manual operated or event-dependent devices, with
or without software controlled functions, the integrator shall declare whether the device once
triggered, follows a pre-programmed cycle, or whether the transmitter remains on until the
trigger is released or the device is manually reset. The integrator shall also give a description of
the application for the device and include a typical usage pattern. The typical usage pattern as
declared by the integrator shall be used to determine the duty cycle and hence the duty class.
A110LR09x – User’s Manual Page 23 of 38
Release Date 10/31/11
Where an acknowledgement is required, the additional transmitter on-time shall be included and
declared by the integrator.
In a period of 1 hour, the duty cycle shall not exceed the spectrum access and mitigation
requirement values as given in Table 5. For frequency agile devices without LBT, the duty cycle
shall apply to the total transmission time as given in Table 5, or shall not exceed 0.1 % per
channel in a period of 1 hour.
2.5.2.1.2. LBT & AFA
Listen Before Talk (LBT) is used to share spectrum between SRD transceiver equipment with
similar power and bandwidth. In order to make maximum use of the available channels,
intelligent or polite equipment may use a Listen Before Talk (LBT) protocol with a preferred
option of Adaptive Frequency Agility (AFA). AFA is defined as the capability of an equipment to
dynamically change channel within its available frequencies for proper operation.
LBT (Listen Before Talk) functionality is built in the A110LR09X modules, and the approved
configurations are made to meet the LBT Threshold limits. However, LBT timing parameters,
specific to the end product, have to be established through controlling software and
declared by the OEM integrator or end-product developer in the product user manual or
user guide. A brief description and limits of these parameters are given as follows:
Minimum Transmitter off-time is the period where a specific transmitter shall remain
off after a transmission or a communication dialogue between units or a polling
sequence of other units on the same frequency. The minimum TX off-time has to be
greater than 100 ms.
LBT minimum listening time is the minimum time that the equipment listens for a
received signal at or above the LBT threshold level immediately prior to transmission to
determine whether the intended channel is available for use.
LBT minimum listening time, tL, has two parts: the fixed part, tF, and the pseudo random
part, tPS. tL = tF + tPS. The fixed part of the minimum listening time is 5 ms. The pseudo
random part has to be randomly varied between 0 ms and 5 ms or more in equal steps
of 0.5 ms as the following:
o If the channel is free from traffic at the beginning of the listen time, and remains
free throughout the fixed part of the listen time, then tPS is automatically set to
zero by the equipment itself
o If the channel is occupied by traffic when the equipment either starts to listen or
during the listen period, then the listen time commences from the instant that the
intended channel is free. In this situation the total listen time tL shall comprise tF
and the pseudo random part, tPS.
Algorithmic details and values have to be declared by the provider of the equipment.
Maximum dead time is the period between the end of the listening time and the start of
the transmission. The maximum dead time cannot exceed 5 ms.
Page 24 of 38 A110LR09x – User’s Manual
Release Date 10/31/11
Maximum transmitter on-time is the maximum time the transmitter can be on during:
o A single transmission. The limit is 1 s, and the actual value has to be declared.
o Multiple transmissions and acknowledgements for a communication dialogue or
polling sequence of other units under the condition that the channel is free. The
limit is 4 s, and the actual value has to be declared.
o Within 1 hour for any 200 kHz of spectrum. The limit is 100 s.
NOTE: Longer accumulated transmission time is possible by implementing more AFA channels.

3.5. Power Supply Considerations
Noise on the power supply line reduces the sensitivity of a receiver and modulates onto a
transmitter’s signal, both of which causes a degradation of link quality and hence a reduction in
range.
The A110LR09A and A110LR09C radio modules each have an integral ferrite bead in the
supply line from pin 18 (Vdd) and decoupling capacitance to reduce any noise on the incoming
power supply line. This arrangement will eliminate most supply voltage noise. In particularly
noisy environments (switching regulators, motor controls, etc.), it may be necessary to add
additional noise reduction means.
Pin 7 (Vdcoup1) is connected to the modules internal supply line after the ferrite bead and
decoupling capacitors and can be used to probe the noise at module level. The noise level
measured on pin 7 should not exceed 120mVpp when in transmit or receive mode; it may
however exceed this value when setting up or accessing data to/from the FIFOs, while not
actively transmitting or receiving.
If the level measured is exceeding the above limit, steps should be taken to ensure maximum
range, including:
Adding decoupling capacitance to pin 7 (Vdcoup1).
Adding additional filtering in the supply line.
Adding an LDO in the supply line (the TPS734xxx low Dropout Regulator from TI is
recommended).

4.3. Soldering
AIR Modules may be mounted either manually (for prototyping or low volume production), or
automatically for high-volume production.
A no-clean tin/silver/copper (SAC) solder is recommended, however lead based no-clean
pastes may also be used.
CAUTION: AIR Modules are designed for no-clean fluxes only. DO NOT use water-
based fluxes that require aqueous cleaning after solder. Spot cleaning with a flux
remover and toothbrush may be performed with care.
4.3.1. Manual Mounting Procedure
The recommended soldering method is reflow of a paste solder on a hot plate. This method
works provided the bottom of the board where the AIR module is to be mounted is accessible,
and there are no bottom-side components in the way.
An aluminum or copper block may be placed on the hot plate surface to transfer heat to a
localized area on the board where the AIR module is mounted
- Set the hot plate to the reflow temperature solder manufacturer’s recommended
- Apply solder paste to the pads on the board receiving the AIR module
- Place the AIR module carefully onto the dispensed solder
- Using tweezers or another holding device, carefully place board with AIR module onto
the hot plate surface (or metal block)
- Apply heat until reflow occurs, per solder paste manufacturer’s recommendations
- Carefully remove the board and place on a heat-resistant surface to cool
- Check assembly electrically to confirm there are no opens or shorts
