LW004-CT
Product Introduction
LW004-CT is a LoRaWAN-Based network IoT button specifically designed for contact tracing purposes. It is compact, small in size, and easy to use. It can be used to track close contact and social safety distance reminders. A panic button can be used for SOS function or user-defined panic event. All of the close contact information will be obtained by scanning the incoming data from nearby BLE beacons or LW004-CT. And it will send these data to the nearest LoRaWAN gateway. The LoRaWAN gateway then transmits this data over to the cloud server. Once this data reaches the cloud, it is accessible all over the world 24/7.

Related Bluetooth chip introduction:
The nRF52 Series 2.4 GHz RF transceiver is designed and optimized to operate
in the worldwide ISM frequency band at 2.402 to 2.48 GHz. Radio modulation
modes and configurable packet structure enable interoperability with
Bluetooth® low energy (BLE), ANT™, Enhanced ShockBurst™, and other 2.4 GHz
protocol implementations. The transceiver receives and transmits data directly
to and from system memory for flexible and efficient packet data management.
The nRF52832 Series transceiver has the following features:
- General modulation features
- GFSK modulation
- Data whitening
- On-air data rates
- 250 kbps
- 1 Mbps
By using the reference signal (32MHz) currently used by the external clock input, a stable RF signal and the table baseband clock are generated. For more information, please refer to the following website. https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52832

FCC Instructions:
This product 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 product generates uses, and can radiate radio
frequency energy and, if not installed and used
in accordance with the instructions, may cause harmful interference to radio
communication. However, there is no guarantee that interference will not occur
in a particular installation. If the product does cause harmful interference
to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the product and receiver.
– Connect the product 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
(2) this device must accept any interference received, including interference
that may cause undesired operation.
Warning: Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
product. FCC Radiation Exposure Statement:
The equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
a minimum distance 5mm between the radiator and your body. For more
information, please refer to the following website.
