As the Internet of Things (IoT) continues to grow, so does the demand for wireless communication technology. Chirp narrowband spread spectrum technology is a wireless communication technology with wide application potential, which has unique advantages in low power consumption, wide area coverage, and anti-interference. This paper describes how to build an ECWAN wireless hybrid network using PanTeach's Chirp technology, and use a multi-role smart metering socket as a Chirp WAN base station to achieve low-power, edge computing, and large-scale IoT applications.

Chirp narrowband spread spectrum technology

Chirp narrowband spread spectrum technology is a technology with important application prospects in the Internet of Things and wireless communication. Its core idea is to encode and decode data signals through frequency changes, thereby improving the reliability and coverage of communications. As a well-known enterprise in the field of low-power narrowband Chirp IoT technology, Panqi Microelectronics has launched a new generation of ChirpIoT™ terminal chips with stronger performance through continuous technology iteration, achieving another breakthrough in Chirp technology by domestic manufacturers with higher sensitivity, higher speed and lower power consumption.

The CHIRP signal has the following five significant advantages: First, the chip implementation complexity is low and the power consumption is low. Second, the spread spectrum gain is large and the sensitivity is high. Third, it has a good ability to resist narrow-band interference. Fourth, the tolerance of frequency deviation is large and the frequency resolution is strong. Fifth, it has a strong ability to resist multipaths.

In terms of phase modulation technology, Panqi Micro has developed the PSK-Chirp technology, which can achieve a transmission rate increase of about 33% without loss of performance compared with the original Chirp technology. In terms of signal, chaotic technology has the characteristics of non-periodic, random and unpredictable, and Chirp technology has the characteristics of low power consumption, high performance and anti-interference.

ECWAN wireless hybrid networking

ECWAN is an innovative wireless networking architecture that integrates different wireless technologies, including Chirp technology, to meet multiple application requirements. The core idea of ECWAN is to incorporate edge computing into wireless communications, pushing data processing and decision-making to the edge of the network, thereby improving efficiency and responsiveness.

In ECWAN, Chirp technology is used as a communication protocol for wide-area base stations to establish the underlying connection. A WAN base station can be a multi-role smart metering socket that is not only a power management device, but also a Chirp communication node. The use of this multi-role device makes full use of hardware resources and reduces system complexity.

Key features of ECWAN include:

1. Edge computing: ECWAN pushes computing and decision-making to the edge of the network, reducing the need for data transmission, reducing network latency, and improving privacy protection.

2. Hybrid networking: ECWAN integrates different wireless technologies, including Chirp technology, to achieve diverse application requirements. This hybrid networking can provide the best performance in different scenarios.

3. Low power consumption: ECWAN uses Chirp technology as the communication protocol, which can achieve low-power communication and extend the battery life of the device.

4. Large-scale deployment: ECWAN is suitable for large-scale IoT applications, covering various scenarios such as hospitals, schools, and laboratories.

ALM multi-role smart metering socket

The multi-role smart metering socket is a key component of the Chirp wide-area base station. It is a device that can monitor and control the safe energy consumption of the electrical load, and can also be used for scene perception and positioning of the base station. The outlets intelligently monitor and control power consumption, helping users manage power usage more effectively and reduce energy consumption and carbon emissions.

In addition, the smart metering socket also has the function of scene awareness and positioning base station. This means that it can provide scene awareness by sensing and recognizing surrounding objects and the environment, such as determining whether a device is near an outlet, or recognizing a specific action or event. At the same time, it can also be used as a positioning base station to provide location-based services, such as positioning and navigation.

This device has multiple features, including:

Power Management: Multi-role smart metering outlets can effectively manage power distribution, reduce energy consumption, and ensure long-term operation of equipment.

Chirp Communication Node: As a Chirp communication node, it can communicate with other Chirp devices to achieve wireless connectivity with wide area coverage.

Edge computing: The multi-role smart metering socket has built-in edge computing capabilities, which can perform data processing and analysis locally on the device.

It can monitor and control the safe energy consumption of the electrical load, and can also be reused for scene perception and positioning base stations. For example, the status monitoring, trigger response and power consumption mode management of environmental sensors and human presence sensors, and the flexible positioning and tracking of equipment asset tags and personnel and employee badges.

Edge computing

1. The so-called edge computing is the computing closer to the edge than the central computing. Edge computing is a relative concept, and "near the edge" can refer to both the physical proximity of the physical space and the logical proximity of the computing domain.

2. Edge computing is oriented to device objects in the edge network, especially for data collection sources. As a result, edge computing can greatly improve data efficiency (e.g., reducing data redundancy) and the real-time nature of incident response (necessary decision-making).

3. Cloud edge computing emphasizes collaborative data computing logic, and the undertaker can be either an edge server relative to the central server, or an edge computing layer/module relative to the business layer/module in the same server, to manage and process data on the hardware devices in the edge network.

4. Since edge computing is oriented to edge object device data, it must be completed by [cloud-edge collaboration]. Therefore, edge computing includes both cloud edge computing and network edge computing (i.e., computing undertaken by intelligent hardware devices in the edge network).

5. Edge computing needs more [edge collaboration] to complete. With the further development of the concept and technology of edge computing, [edge collaborative computing] has not only received the attention of industry technical experts, but also has achieved good application results in the field of industrial Internet of Things. 

6.The efficiency of collaboration between edge network devices (including between service nodes, nodes and service objects) is improved through [edge collaborative perception" (such as dynamic identification and matching, state triggering, role reuse, balance optimization, elastic mode management, etc.), aiming to improve the elastic data efficiency and balance stability of [edge collaborative computing].

In general, the value of edge computing is reflected in many aspects, and the technology and application trends also indicate its broad development prospects. The undertaker of edge computing should not only emphasize the computing undertaken by the core intelligent gateway and base station in the edge domain (note: this is basically the current industry concept and technical status), but also give full play to the edge computing role of any intelligent service node in the edge wireless network, especially the multi-role multiplexing equipment node.

Collaborative services (such as data collection, transmission, control, and perception management) for surrounding low-power target devices require intelligent wireless networks with edge collaborative computing capabilities.
