One of the biggest dark horses in IoT low-power WAN (wan) technology, rpma technology, has made its way to China. Back in January, John Horn, CEO of Essence, which owns the rpma technology, personally visited Wuxi, lpwa standardwhere he plans to settle and gradually expand the IoT infrastructure with rpma as the core technology throughout China. Ltd. to establish Wuxi Jiuzhou Telecom Co., Ltd. as the only Chinese continent where Seiko will promote rpma technology and application.

RPMA Technology Introduction

RPMA, full name Random Phase Multiple Access, officially translated in Chinese as \ "Random Phase Multiple Access\", is a kind of Low Power Wide Area Network (LPWA) technology in the field of Internet of Things.

And what is LPWA?

LPWA, known as Low Power Wide Area, is a kind of low-power wide area network, which is an IoT wireless connection technology introduced in recent years to meet the demand of long-range low-power communication in IoT. It has the features of long transmission distance, low power consumption, simple network structure and low operation and maintenance cost. The emergence of low-power WAN technology fills the gap of existing communication technologies and lays the foundation for the large-scale development of IoT.

Coverage and connection cost of major communication technologies

For consumer-grade IoT applications, Wi-Fi, ZigBee and Bluetooth are ideal short-range wireless network technologies, but for a wider range of civil, industrial and other IoT long-range applications, cellular networks or satellites can meet the requirements, but these technologies are not competitive in terms of cost, power consumption and scalability. Therefore, with the development of IoT technology, Low Power Wide Area Network (LPWA) technology has emerged.

Low Power Wide Area Network (LPWA) technology can be used for a wide range of purposes, such as parking lot information resources, traffic flow control of transportation systems, utility facility monitoring, power distribution management control, and social and environmental accounting monitoring of civil enterprise infrastructure education facilities is just the beginning, while agricultural production applications such as crop growth and development monitoring and livestock migration also require WAN coverage; from Asset monitoring and tracking, from cabs to refrigerated freight, requires regional, national, or even global network service coverage. Transportation such as railways and highways as basic teaching facilities also need wide area surveillance; even consumer applications such as healthcare can benefit from WAN links that replace cellular telephony.

With wide coverage, low service cost and low energy consumption, LPWA can meet the needs of IoT social environment. With low frequency of wide-area data exchange, low connection cost, and easy roaming point switching, LPWA is an ideal link for the connection requirements of complex environments.
