LoRa Based Vehicle Asset Tracker

Changes or modifications not expressly approved by the manufacturer could void the

user’s authority to operate the equipment

Federal Communication Commission Statement (FCC, U.S.)

This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable

protection against harmful interference in a residential installation. This equipment generates,

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver

is connected.

• Consult the dealer or an experienced radio/TV technician for help.

• This device complies with Part 15 of the FCC Rules. Operation is subject to the following

two conditions: (1) This device may not cause harmful interference, and (2) this device

must accept any interference received, including interference that may cause undesired

operation.

provide at least 20 cm separation from the human body at all times.

Afin de se conformer aux exigences d’exposition RF FCC / ISED, cet appareil doit être installé

pour fournir au moins 20 cm de séparation du corps humain en tout temps.

The term “IC:” before the certification/registration number only signifies that registration was

performed based on a Declaration of Conformity indicating that Industry Canada technical

specifications were met. The term “IC:” before the certification/registration number does not

imply that Industry Canada approved the equipment.

ISED RSS Notice:

This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the

following two conditions:

1. This device may not cause interference;

2. This device must accept any interference, including interference that may cause undesired

operation of the device.

Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio

exempts de licence. L’exploitation est autorisée aux deux conditions suivantes:

1. l’appareil ne doit pas produire de brouillage;

2. l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est

The device has only one user serviceable part, which is the battery. The device has a reed

switch as the only user control, which is used to trigger a position capture. All operation is self

contained. The device will only use one radio.

RF Circuit Function 915MHz

The main microcontroller assembles data packets for the Semtech SX1272 transceiver to

modulate the data using LoRa modulation. LoRa modulation is a derivative of Chirp Spread

Spectrum. The transceiver uses a pSemi 4259-63 RF switch to control if the custom trace

antenna is connected to the receive or transmit pins of the SX1272.

Antenna Setup 915MHz

The antenna is not changeable by the user, it is a copper trace in the PCB and contained within

915MHz Channels

There are 64 channels with 125kHz bandwidth each starting at 902.3MHz and increasing by

selected it will use the bandwidth assigned to that channel (125kHz for channels 0-63 and

500kHz for channels 64-71). The device will send the entire packet on that 1 channel in under

400 milliseconds. The device will not attempt to transmit again until after 20 seconds have

passed (it will be a random time between 20 and 50 seconds) if another data packet has been

queued. The choice between 125kHz channel or 500 kHz channel is random, with 64 125kHz

channels and 8 500kHz channels the device is much more likely to transmit on a 125kHz

channel. The device will make sure not to reuse the last channel transmitted on when picking

the new random channel.

Steps to Transmit

1. Randomly select a channel between 0-71 making sure it was not used on the last

transmit

4. Turn off transceiver for a random time between 20-50 seconds
