DESIGN CONSIDERATIONS
Chapter 2 – Design Considerations
USB Design
MultiTech recommends that you review Intel's High Speed USB Platform Design Guidelines for information about
USB signal routing, impedance, and layer stacking. Also:
Shield USB cables with twisted pairs (especially those containing D+/D-).
Use a single 5V power supply for USB devices. See Power Draw for current (ampere) requirements.
Route D+/D- together in parallel with the trace spacing needed to achieve 90 ohms differential impedance
for the USB pair and to maintain a 20 mil space from the USB pair and all other signals.
If power is provided externally, use a common ground between the carrier board and the device.
Your device may not power up on all Host PCs or host USB devices due to the higher current requirements
of the cellular radio. Check your particular USB host port or PC motherboard's electrical specs for details on
max current capabilities of the particular USB port you are trying to use.
Depending on your design, you may be able to use a dual USB cable to share the current between two low
power USB ports or create a custom USB cable that provides external power.
Noise Suppression Design
Adhere to engineering noise-suppression practices when designing a printed circuit board (PCB). Noise suppression
is essential to the proper operation and performance of the modem and surrounding equipment.
Any OEM board design must consider both on-board and off-board generated noise that can affect digital signal
processing. Both on-board and off-board generated noise that is coupled on-board can affect interface signal levels
and quality. Noise in frequency ranges that affect modem performance is of particular concern.
On-board generated electromagnetic interference (EMI) noise that can be radiated or conducted off-board is
equally important. This type of noise can affect the operation of surrounding equipment. Most local government
agencies have certification requirements that must be met for use in specific environments.
Proper PC board layout (component placement, signal routing, trace thickness and geometry, and so on)
component selection (composition, value, and tolerance), interface connections, and shielding are required for the
board design to achieve desired modem performance and to attain EMI certification.
Other aspects of proper noise-suppression engineering practices are beyond the scope of this guide. Consult noise
suppression techniques described in technical publications and journals, electronics and electrical engineering text
books, and component supplier application notes.
Electromagnetic Interference
The following guidelines are offered specifically to help minimize EMI generation. Some of these guidelines are the
same as, or similar to, the general guidelines. To minimize the contribution of device-based design to EMI, you
must understand the major sources of EMI and how to reduce them to acceptable levels.
Keep traces carrying high frequency signals as short as possible.
Provide a good ground plane or grid. In some cases, a multilayer board may be required with full layers for
ground and power distribution.
Decouple power from ground with decoupling capacitors as close to the device's power pins as possible.
6 QuickCarrier™ USB-E MT100UCC-EV3 Developer Guide
DESIGN CONSIDERATIONS
Eliminate ground loops, which are unexpected current return paths to the power source and ground.
Decouple the telephone line cables at the telephone line jacks. Typically, use a combination of series
inductors, common mode chokes, and shunt capacitors. Methods to decouple telephone lines are similar to
decoupling power lines; however, telephone line decoupling may be more difficult and deserves additional
attention. A commonly used design aid is to place footprints for these components and populate as
necessary during performance/EMI testing and certification.
Decouple the power cord at the power cord interface with decoupling capacitors. Methods to decouple
power lines are similar to decoupling telephone lines.
Locate high frequency circuits in a separate area to minimize capacitive coupling to other circuits.
Locate cables and connectors to avoid coupling from high frequency circuits.
Lay out the highest frequency signal traces next to the ground grid.
If using a multilayer board design, make no cuts in the ground or power planes and be sure the ground
plane covers all traces.
Minimize the number of through-hole connections on traces carrying high frequency signals.
Avoid right angle turns on high frequency traces. Forty-five degree corners are good; however, radius turns
are better.
On 2-layer boards with no ground grid, provide a shadow ground trace on the opposite side of the board to
traces carrying high frequency signals. This will be effective as a high frequency ground return if it is three
times the width of the signal traces.
Distribute high frequency signals continuously on a single trace rather than several traces radiating from
one point.
Electrostatic Discharge Control
Handle all electronic devices with precautions to avoid damage due to the static charge accumulation.
See the ANSI/ESD Association Standard (ANSI/ESD S20.20-1999) – a document “for the Development of an
Electrostatic Discharge Control for Protection of Electrical and Electronic Parts, Assemblies and Equipment.” This
document covers ESD Control Program Administrative Requirements, ESD Training, ESD Control Program Plan
Technical Requirements (grounding/bonding systems, personnel grooming, protected areas, packaging, marking,
equipment, and handling), and Sensitivity Testing.
MultiTech strives to follow these recommendations. Input protection circuitry is incorporated in MultiTech devices
to minimize the effect of static buildup. Take precautions to avoid exposure to electrostatic discharge during
handling.
MultiTech uses and recommends that others use anti-static boxes that create a faraday cage (packaging designed
to exclude electromagnetic fields). MultiTech recommends that you use our packaging when returning a product
and when you ship your products to your customers.

CELLULAR INFORMATION
Chapter 3 – Cellular Information
Antenna System Cellular Devices
The cellular/wireless performance depends on the implementation and antenna design. The integration of the
antenna system into the product is a critical part of the design process; therefore, it is essential to consider it early
so the performance is not compromised. If changes are made to the device's certified antenna system, then
recertification will be required by specific network carriers.

Carrier Specific Information
Notice for Devices that Use Aeris Radios
One component of your device is a radio. A radio algorithm prevents your device from repeatedly attempting to
connect to the network when the radio:
Cannot establish a packet data connection or
Fails to access the application server.
When writing applications for your devices, ensure that your applications do not interfere with the radio's
connection retry algorithm. If you fail to do so, Aeris might block network access for your devices.
After your devices reach the end of their commercial lifespan, you must remove them from the Aeris network. To
do so, remove power from the devices and remove their antennas. If your devices continue to attempt to register
with the network after you cancel device subscriptions, Aeris can bill you for any traffic generated by those
devices.
MultiTech Sprint Approved Device Requirements
Any changes to a Sprint approved MultiTech device circuit board or antenna system requires you to contact Sprint
certifications. Sprint will determine if additional testing is required due to modification of the approved device
circuit board or antenna system.
All applications interacting with Sprint approved MultiTech devices must be written in a manner where they do not
interfere/ interrupt the Sprint HFA process or OMA-DM processes outlined in section labeled Telit OMA DM
Notifications.
If the MultiTech device will be co-located with any other transmitters you will be required to submit your device to
an FCC approved lab for additional FCC testing.
If the Sprint approved MultiTech device/circuit board is embedded into another device/circuit board be aware you
will be required to perform EMC and safety testing on your end device.
Sprint OMA DM Notifications
Applications should look for the following unsolicited OMA indications at all times:
#904 HFA Started
#905 PRL - Session started
#906 DC - Session started
12 QuickCarrier™ USB-E MT100UCC-EV3 Developer Guide

#907 FUMO -Session started
If application sees one of these indications it should not attempt to issue commands, attempt data connection, or
reset device until the OMA process is complete as indicated by additional #9XX OMA success or failure indications
below.
If the device is in a data connection at the time a Network Initiated PRL, DC, or FUMO update alert message is
received from Sprint, the radio may close the data connection and start OMA-DM process with a #9xx indication.
When this occurs the application should not attempt to issue AT commands, attempt to start data connection
again, or reset device in an attempt to regain control. Application should wait for a #9xx indication the process has
completed before proceeding.
Be aware after the HFA process is successfully completed the radio will be reset. The radio may also reset after
other OMA functions.

regarding the use of radio equipment. Follow the safety advice given below.
Operating your device close to other electronic equipment may cause interference if the equipment is
inadequately protected. Observe any warning signs and manufacturers’ recommendations.
Different industries and businesses restrict the use of cellular devices. Respect restrictions on the use of
radio equipment in fuel depots, chemical plants, or where blasting operations are in process. Follow
restrictions for any environment where you operate the device.
Do not place the antenna outdoors.
Switch OFF your wireless device when in an aircraft. Using portable electronic devices in an aircraft may
endanger aircraft operation, disrupt the cellular network, and is illegal. Failing to observe this restriction
may lead to suspension or denial of cellular services to the offender, legal action, or both.
Switch OFF your wireless device when around gasoline or diesel-fuel pumps and before filling your vehicle
with fuel.
Switch OFF your wireless device in hospitals and any other place where medical equipment may be in use.
Interference with Pacemakers and Other Medical Devices
Potential interference
Radio frequency energy (RF) from cellular devices can interact with some electronic devices. This is
electromagnetic interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted
cardiac pacemakers and defibrillators from cellular devices. This test method is part of the Association for the
Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that
cardiac pacemakers and defibrillators are safe from cellular device EMI.
The FDA continues to monitor cellular devices for interactions with other medical devices. If harmful interference
occurs, the FDA will assess the interference and work to resolve the problem.
Precautions for pacemaker wearers
If EMI occurs, it could affect a pacemaker in one of three ways:
Stop the pacemaker from delivering the stimulating pulses that regulate the heart's rhythm.
Cause the pacemaker to deliver the pulses irregularly.
Cause the pacemaker to ignore the heart's own rhythm and deliver pulses at a fixed rate.
Based on current research, cellular devices do not pose a significant health problem for most pacemaker wearers.
However, people with pacemakers may want to take simple precautions to be sure that their device doesn't cause
a problem.
Keep the device on the opposite side of the body from the pacemaker to add extra distance between the
pacemaker and the device.
Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt or
jacket pocket directly over the pacemaker).

Note: The radio's performance may be affected at the temperature extremes. This is considered normal. The radio
is designed to automatically fallback in class and reduces transmitter power to avoid damage to the radio. There is
no single cause for this function. Rather, it is the result of an interaction of several factors, such as the ambient
temperature, the operating mode and the transmit power.
You may need to reduce the temperature range if airflow is limited around the cellular radio. Test and verify the
temperature range if the QuickCarrier USB-E is designed into an enclosed chassis.

CONFIGURING AND COMMUNICATING WITH YOUR DEVICE
Chapter 9 – Configuring and Communicating with
Your Device
Interacting with Your Device Overview
This section describes how to use AT commands to interact with your device. Using terminal software such as
Kermit, you can issue AT commands to communicate with and configure your modem. The AT commands let you
establish, read and modify device parameters and help you control how the device operates. This section
documents basic interactions with your device, such as verifying signal strength and network registrations, sending
and reading SMS text messages, and sending and receiving data.
Generally, USB modems are used as unintelligent bit pipes. In Windows, this means you create a dial-up network
connection that uses the Windows IP stack to use the modem to create a PPP connection to the cellular network.
The modem is assigned an IP address from the cellular carrier. This connection provides Internet access and is the
basis for TCP/IP communication for sending and receiving email, creating TCP/UDP Sockets, or putting and getting
files from an FTP server.
In Linux, PPPD is used to dial the modem and create the connection to the cellular TCP/IP network. This provides
Internet access for sending and receiving email, creating TCP/UDP Sockets, or putting and getting files from an FTP
server.
Before Using the Device
Before using the device:
Install any drivers. Refer to the separate driver installation guide for your device.
Power up your device and ensure it is connected to your computer that issues AT commands.
Install terminal software that can communicate with the device, such as HyperTerminal, Tera Term, Kermit,
or Putty.
Using Command Mode and Online Data Mode
Modems have two operation modes, command and online data. After power up, the modem is in command mode
and ready to accept AT commands.
Use AT commands to communicate with and configure your modem. These commands establish, read, and modify
device parameters and control how the modem works. The device also generates responses to AT commands that
help determine the modem’s current state.
If the modem is in online data mode, it only accepts the Escape command (+++).
To send the modem AT Commands from terminal emulation software, set the software to match the modem’s
default data format, which is:
Speed: 115,200 bps
Data bits: 8
Parity: none
Stop bit: 1
Flow control: hardware
QuickCarrier™ USB-E MT100UCC-EV3 Developer Guide 27
