COTX-X3 Hotspot Miner


COTX-X3 Hotspot Indoor Miner is a new convergent and intelligent indoor gateway developed independently by Beijing COTX Networks Technology Co. Ltd. (COTX) for mining HNT (Helium).

Supports the standard LoRaWAN formulated by the International LoRa Alliance and other common IoT access protocols, such as Wifi, BLE.

It can be implemented in different conditions with several connection options such as WiFi and Ethernet.

This new Hotspot produced by COTX has integrated: surveillance camera, audio interfaces and built-in OLED screen, it can be accessed in the security system and implemented in the security application.

The built-in low frequency LoRa chip can meet a coverage of 1 km-15 km depending on the actual conditions at the location.

The hotspot can transmit data via the LoRa protocol for low power WAN transmission.

Product features

High level security protection
Hnt Service – COTX-X3 Hotspot Indoor Miner coordinates with the cloud key management system to support high-level security protection.

The entire network adopts a unified key management system to manage the key life cycle.

With overall consideration and excellent professional design, whether the gateway is offline or online, there is a consistent protection and security mechanism, while providing secure data storage and encryption capabilities for securing locally locked data.

The hotspot is integrated into the COTX-X3 Hotspot Miner operating system, which is convenient for network administrators to install third-party software applications. The software application is strictly isolated from the operating system, ensuring the security of the operating system kernel. At the same time, operating system files support digital signatures, and only those system files that have been signed and verified will be updated and run, preventing system files from being maliciously modified and updated.

  1. Comprehensive and diverse options for backhaul
    Hnt Service – COTX-X3 Indoor Miner Hotspot supports several uplink access methods, such as WiFi and Ethernet, giving users flexible and diverse uplink options when deploying complex networks:➢ Access to the WiFi infrastructure network can be chosen.Flexible and easy to implement
    The extremely compact hardware design of the COTX-X3 Hotspot Miner has created its Mini size: 95mm * 75mm * 29mm, which is extremely easy to transport and implement.At the same time, it facilitates hardware integration and secondary development and redefines the product at the IoT operating level.Multi-service interface and rich analysis capabilities
    application scenariosHnt Service – COTX-X3 Indoor Miner Hotspot has multiple interfaces, supports common IoT access protocols such as LoRa, WiFi, BLE, allows access to third parties that comply with the standard LoRaWAN protocol and supports the extension of multimedia services such as Video and Audio.

Smart agriculture, forestry and animal husbandry

In the field of agriculture, forestry and animal husbandry, environmental data from agricultural fields, greenhouses, livestock and crop production data are effectively returned, which can provide data support for scientific reproduction;

Tracking and searching for grazing herds to ensure the safety of the property of farmers and shepherds.
Smart Park

In the smart building scenario, COTX-X3 Hotspot Miner can connect the building’s internal facilities and collect data to the platform to meet the requirements of business processing :

1) It has such functions: networking of consumer equipment, reporting data on energy consumption, monitoring energy consumption 7 * 24 hours, reducing the manual fee and reducing costs. It can optimize energy management and control based on energy consumption data.

2) With the help of the gateway camera and the audio service interface, the security system of the park is connected to carry out the security control of the visitors.

3) With the camera and audio interface, the gateway is connected to the park’s security system, which can perform visitor security control

4) The equipment of the assets connects to the network, tracking and searching for important assets can be done through the gateway in the park
