Important Notice
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.
Safety and Hazards
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.
Note:
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.
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.
Limitations of Liability
This manual is provided “as is”. Sierra Wireless makes no warranties of any kind, either expressed or
implied, including any implied warranties of merchantability, fitness for a particular purpose, or
noninfringement. The recipient of the manual shall endorse all risks arising from its use.
The information in this manual is subject to change without notice and does not represent a
commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES
SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL,
GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING,
BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR
REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY
THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability
arising under or in connection with the Sierra Wireless product, regardless of the number of events,
occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the
Sierra Wireless product.
Customer understands that Sierra Wireless is not providing cellular or GPS (including A-GPS)
services. These services are provided by a third party and should be purchased directly by the
Customer.


Supports bit-pipe (Essential Module Series) and value add (Smart Module Series) solutions

Offers electrical and functional compatibility

Provides Direct Mount as well as Socketability depending on customer needs

FCC Regulations
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE – FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
The HL7588 module has been granted modular approval for mobile applications. Integrators may use
the HL7588 module in their final products without additional FCC certification if they meet the
following conditions. Otherwise, additional FCC approvals must be obtained.
1. At least 20 cm separation distance between the antenna and the user’s body must be
maintained at all times.
2. To comply with FCC regulations limiting both maximum RF output power and human
exposure to RF radiation, the maximum antenna gain including cable loss in a mobileonly exposure condition must not exceed:

TBD 7.51 dBi in Band 2

TBD 5.78 dBi in Band 4

TBD 9.72 dBi in Band 5

TBD 10.17 dBi in Band 13

TBD 9.74 dBi in Band 17
3. This device and its antenna(s) must not transmit be co-located or operating in conjunction
with any other antenna or transmitter, except in accordance with FCC multi-transmitter RF
exposure product procedures.
4. The RF signal must be routed on the application board using tracks with a 50Ω
characteristic impedance. Basically, the characteristic impedance depends on the
dielectric, the track width and the ground plane spacing. In order to respect this constraint,
Sierra Wireless recommends using MicroStrip or StripLine structure and computing the
Tracks width with a simulation tool (like AppCad shown in the figure below and that is
available free of charge at http://www.agilent.com).
TBC
Rev 1.0
July 28, 2015

User Guide
FCC Regulations
If a multi-layered PCB is used, the RF path on the board must not cross any signal (digital,
analog or supply).
If necessary, use StripLine structure and route the digital line(s) "outside" the RF structure. An
example of proper routing is shown in the figure below.
Stripline and Coplanar design requires having a correct ground plane at both sides.
Consequently, it is necessary to add some vias along the RF path. It is recommended to use
Stripline design if the RF path is fairly long (more than 3cm), since MicroStrip design is not
shielded. Consequently, the RF signal (when transmitting) may interfere with neighbouring
electronics (AF amplifier, etc.). In the same way, the neighbouring electronics (microcontrollers, etc.) may degrade the reception performances. The antenna connector is
intended to be directly connected to a 50Ω antenna and no matching is needed.
5. A label must be affixed to the outside of the end product into which the HL7588 module is
incorporated, with a statement similar to the following:
This device contains FCC ID: N7NHL7588
6. A user manual with the end product must clearly indicate the operating requirements and
conditions that must be observed to ensure compliance with current FCC RF exposure
guidelines.
The end product with an embedded HL7588 module may also need to pass the FCC Part 15
unintentional emission testing requirements and be properly authorized per FCC Part 15.
