VLU11 Operation description

The VLU11 is a stolen vehicle recovery system (SVR), a single box enclosure incorporating a processor,
VHF Silent Radio Transceiver, GPS receiver, wireless data modem in addition to BLE chip transceiver,
vehicle-rated power supply.

VHF LoJack:

Transmits on a radio (RF) carrier frequency of 173.075 MHz.

There are two modes of operation for the low jack radio:
The tracking mode is activated whenever the vehicle is reported as stolen. In tracking mode the radio
transmits for 200 ms every 1 s.
Vehicles with the system installed send a 200 millisecond (ms) chirp every fifteen seconds on this
frequency when the car moves without a proper identification of the car key.

Under all other conditions the radio is in receive only mode.

The max power setting to the transmitter is as per settings used in testing and in the production is 33.62
dBm. The CC1125 low jack radio chip is set to 16 dBm output power. The power amplifier stage will
amplify by 17.5 dB.
The expected gain of the whip antenna is about -10 dBi.

Lowjack supports FSK modulation

BLE (Bluetooth LE): is optional and use 2.4GHz designed by CalAmp wireless network based on the Texas
instrument Chip CC2640 and operation range on 2402 - 2480 MHz bands and using Custom designed
antenna with peak gain of 5.36 dBi. The max power setting to the transmitter is as per settings used in
testing and in production is 0 dBm

The cellular connectivity: provided by uBlox Sara-R410M certified under grants below:

FCC ID: XPY2AGQN4NNN

ISED: 8595A-2AGQN4NNN

The module without modification as delivered by UBlox is used and hence the default module power
settings are delivered to the antenna.
The used antenna is also a custom design for the product with 2.58 dbi peak gain.
