2.0 Developer Guide (PN S000610) for more information.

Powering Down The Device

CAUTION: Failing to properly power down the device before removing power may corrupt your device's file

system.

To properly power down your device, use the following sequence:

1. Issue the AT+QPOWD command or hold the reset line (pin 35) low.

2. Wait up to 65 seconds for POWERED DOWN message or until RADIO_VDD (pin 27) goes low.

3. Remove power to the MTQ.

Device Reset (Pin 35)

Minimum pulse is 50 ms.

- If the reset line is held low for >50ms the radio is turned off.

- When the reset line is released, the radio is turned on.

Note: A supervisory processor handles this function as issuing a direct reset to the radio is not recommended.

SMA to U.FL Cables

The developer kit includes three 4.5" SMA to U.FL cables which are preinstalled on the developer board. Consult
the mechanical drawings for your device to determine which antenna to connect to which U.FL connector on the
device.

Connecting an Antenna through the Developer Board Connectors

To connect an antenna to the device through the developer board:

1. Determine which SMA connector you want to use for the antenna.

2. Finger tighten the antenna to the SMA connector.

3. Attach the U.FL connector from the cable to the connector on the device.

D = Diversity

DragonflyTMMTQ-LEU7 Device Guide 17

ANTENNAS

Antenna Diversity

Antenna diversity uses two receive antennas to improve the downlink connection (cell tower to mobile). It has no
effect on the uplink (mobile to cell tower).

Antenna diversity is useful in environments where the signal arrives at the device after bouncing off or around
buildings or other objects. The bounced signal may be attenuated by going through semi-transparent (to the
signal) objects. Each signal alteration can change its magnitude, phase, orientation, or polarization. This complex
environment can exist in cities, inside buildings or in traffic. In this environment, signal paths from the cell tower
form an interference pattern of peaks and nulls. These peaks and nulls can be very close together.

Antenna diversity provides an advantage in complex environments because if one receive antenna has a poor
signal due to an interference null pattern, the other antenna is likely not in the null and has better reception. The
radio compares the reception from both receive antennas and uses the one with the strongest signal.

Antenna diversity is unnecessary when the device has an unobstructed signal path from the cell tower, such as in a
flat area away from buildings. In good reception environments, the product application might prohibit using two
receive antennas.

Using Antenna Diversity

You can use an AT command to turn antenna diversity on and off. When antenna diversity is on and a like or
similar antenna is installed on both radio connectors, the radio automatically chooses the antenna with the best
reception. To learn about the AT command used to control diversity, see the AT Command Reference guide for
your device.

Placing External Antennas

Antennas are usually a quarter wavelength apart from each other. With multiband radios where the quarter
wavelengths in each band are diverse from each other, this rule may not be practical. Choose spacing based on the
band used most often or the band with connection difficulty. Some environments are harsher on particular bands.
Multi-Tech products have antenna connectors at the best spacing for the product size.

Placing antennas in close proximity to each other is not optimal, but you can do it if necessary. It depends on the
signal strength to and from each antenna.

Selecting Antennas

Select an antenna based on your product and application. Typically, both antennas are the same because either
can be the main receive antenna. However, if the antenna connectors are too close together, use a similar antenna
on a short cable for the second receive only antenna.

Antenna Approvals and Safety Considerations

Note the following:

The carriers conduct antenna diversity tests.
There are no EMC concerns about antenna diversity.
All antennas need to have a minimum flammability rating.
Safety requirements depend on your final product.
Antennas are not approved for outdoor use. Do not extend antennas outside of any building.

18 DragonflyTMMTQ-LEU7 Device Guide

Diversity and Power Draw

There are no significant power draw differences.

Important: You must deploy with two antennas, unless your carrier has authorized you to deploy with one
antenna.

SAFETY INFORMATION

Chapter 5 – Safety Information

Handling Precautions

To avoid damage due to the accumulation of static charge, use proper precautions when handling any cellular
device. Although input protection circuitry has been incorporated into the devices to minimize the effect of static
build-up, use proper precautions to avoid exposure to electronic discharge during handling and mounting the
device.

Radio Frequency (RF) Safety

Due to the possibility of radio frequency (RF) interference, it is important that you follow any special regulations
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.

Sécurité relative aux appareils à radiofréquence (RF)

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).

Vehicle Safety

When using your device in a vehicle:

Do not use this device while driving.
Respect national regulations on the use of cellular devices in vehicles.
