Safety and Hazards
Y
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.
Note:
IN
Do not operate the Sierra Wireless modem in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can interfere such
as explosive atmospheres, medical equipment, or any other equipment which may be susceptible to
any form of radio interference. The Sierra Wireless modem can transmit signals that could interfere
with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is
on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard
systems.
Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door
is open. Sierra Wireless modems may be used at this time.
IM
The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of
a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In
some states and provinces, operating such communications devices while in control of a vehicle is an
offence.

Common Flexible Form Factor (CF3)
3
The AirPrime HL8548 and HL8548-G are Common Flexible Form Factor (CF ) modules.
3
PR
Common Flexible Form Factor (CF ) represents a family of WWAN modules that share the same
mechanical dimensions (width and length with varying thicknesses) as well as a standardized footprint
but can accommodate multiple radio technologies. The modules will have a “common” form factor
across generations of products and for different radio technologies. All modules belonging to this
family can be both solder-down as well as connectorized.

The CF form factor provides a solution to a set of problems faced commonly in the WWAN module
space:

3.10. POWER ON Signal (PWR_ON)
A low level signal has to be provided to switch the AirPrime HL8548 and HL8548-G module ON.
It is internally connected to the permanent 1.8V supply regulator inside the HL8548 and HL8548-G via
a pull-up resistor. Once VBAT is supplied to the HL8548 and HL8548-G module, this 1.8V supply
regulator will be enabled and so the PWR_ON signal is by default at high level.

As PWR_ON is internally pulled up with 200kΩ, a simple open collector or open drain transistor
must be used for ignition.
Note:
IN
VGPIO is an output from the module that can be used to check if the module is active.
When VGPIO = 0V, the module is OFF.
When VGPIO = 1.8V, the module is ON (it can be in idle, communication or sleep mode)
PWR_ON cannot be used to power the module off. To power the module off, use AT command
AT+CFUN=0.
IM
Note:
3.11. Reset Signal (RESET)
EL
To reset the module, a low level pulse must be sent on the RESET pin for 10ms. This action will
immediately restart the AirPrime HL8548 and HL8548-G module. It is therefore useless to perform a
new ignition sequence (PWR_ON) after.
As RESET is internally pulled up, a simple open collector or open drain transistor can be used to
control it.
The RESET signal will reset the registers of the CPU and reset the RAM memory as well, with the
PWR_ON signal at low level.
As RESET is referenced to the VGPIO domain (internally to the module), it is impossible to reset
before the module starts or to try to use RESET as a way to start the module.
PR
Note:
Another more costly solution would be to use MOS transistor to switch the power supply off and
restart the power up procedure using the PWR_ON input line.

The AirPrime HL8548 and HL8548-G module provides a signal, 2G_TX_ON, for TX Burst indication.
The 2G_TX_ON is a 1.8V signal and its status signal depends on the module transmitter state.

EL
During TX burst, there is a higher current drain from the VBATT_PA power supply which causes a
voltage drop. This voltage drop from VBATT_PA is a good indication of a high current drain situation
during TX burst.
The blinking frequency is about 217Hz.
The output logic high duration, Tduration, depends on the number of TX slots and is computed as follows:
T duration = T advance + (0.577ms x number of TX slots) + T delay

AR
4.2.
Y
Apply a LOW level logic to the PWR_ON pin (pin 59); within approximately 25ms, the VGPIO will
appear to be at 1.8V. Either a USB or UART1 interface could be used to send AT commands.
AT command AT+CFUN=0 enables the user to properly switch the AirPrime HL8548 and HL8548-G
module off.
4.3.
IN
If required, the module can be switched off by controlling the power supply. This can be used, for
example, when the system freezes and no reset line is connected to the AirPrime HL8548 and
HL8548-G module. In this case, the only way to get control over the module back is to switch off the
power line.
Sleep Mode Management
(TBC)
AT+KSLEEP=0:
IM
AT command AT+KSLEEP enables sleep mode configuration.
The AirPrime HL8548 and HL8548-G is active when the DTR signal is active (low electrical
level).
When DTR is deactivated (high electrical level), the AirPrime HL8548 and HL8548-G enters
sleep mode after a while.
On DTR activation (low electrical level), the AirPrime HL8548 and HL8548-G wakes up.
EL
AT+KSLEEP=1:
The AirPrime HL8548 and HL8548-G determines when it enters sleep mode (when no more
tasks are running).
“0x00” characters on the serial link wakes the AirPrime HL8548 and HL8548-G up.
PR
AT+KSLEEP=2:
The AirPrime HL8548 and HL8548-G never enters sleep mode.
In sleep mode, the module reduces its power consumption and remains waiting for the wake up
signals either from the network (i.e. read paging block depending on the DRX value of the network) or
the operating system (i.e. timers wake up, timers activated) or the host controller (i.e. character on
serial link or DTR signal).

5. X-Ray Exposure
X-ray exposure results in an undesirable shift in programmed bit threshold voltage of the Flash
memory.
As a result, Sierra Wireless recommends avoiding any X-ray exposure during customer manufacturing
process to ensure software integrity and long term reliability.
Y
In case X- ray inspection could not be eliminated from the customer manufacturing process, a variety
of mitigation methods should be implemented to lower the risk of potential failure:
Use of filter between source and module to minimize exposure to harmful soft X- ray
300µm Zn filter or 1mm Al filter are optimal
Zn and Al absorb soft X-ray to which silicon is particularly vulnerable, and transmit soft
and medium energy X-rays required to obtain good imaging
Minimize X-Ray dose
should be less than 10 RADs
KV peak should be less than 50KV peak
tube current should be less than 20µA
Maximize distance between source and the module
Minimize the X-ray time
use the shortest exposure time possible
sampling only, not 100% inspection
IN

Note that these mitigation guidelines are for information only as it’s NOT possible to provide accurate
acceptable or unacceptable X- ray exposure criteria, e.g. maximum safe dose rate, maximum safe
