15KM long-distance WiFi module maritime WiFi network networking communication achieves full coverage of wireless communication. With the gradual growth of my country's offshore construction, my country's offshore operating platforms have gradually grown. As a staff stationed on offshore platforms, the wind such as signal has become a common saying. Waiting for the weak land signal to blow, has been perplexing every marine operation. Colleagues and resident staff at sea stayed for more than half a month, far away from the shore-based coast, and it was difficult to report to their families that they were safe.
In recent years, with the development of basic communication between my country's sea and shore, long-distance WiFi module network communication gradually covers every corner, and wind will become a history for a period of time. Maritime operators can realize wireless broadband communication and home voice and video chat anytime, anywhere.
Aiming at ultra-long distance and actively exploring broadband wireless communication guarantees, the 15KM long-distance WiFi module further paves the way for a smart ocean, and has put forward a number of excellent solutions for offshore wind power operations, offshore oilfield projects, and network communications for offshore emergency groups. Shore-based communication integration, communication between offshore platforms, and marine emergency rescue provide follow-up communication support services for multiple projects.
Through the marine emergency communication mesh self-organization network, the interconnection of the 15KM long-distance WiFi ship group network, the emergency communication network, and the command and dispatch of the shore-based communication system is realized. At the same time, it realizes unified communication emergency, two-way voice and video intercommunication, and provides multiple communication guarantees for marine search and rescue and marine operation emergency.
The new era of wireless communication is inseparable from the development of software radio (SDR)
With the remarkable development of wireless communication, people's demands for voice and video communication, data transmission, command and control communication and emergency response communication are constantly increasing. The emergence of software radio has become a key indicator to solve people's needs of convenience, efficiency and economy. Due to its unique flexibility, cost-effectiveness, and power consumption advantages, it has greatly facilitated the development of communication technologies, offering enormous benefits to service providers and product developers.
In the context of the current era, radios have become widespread in cell phones, computers, vehicles, and televisions. Traditional hardware radios have a single function that can only be modified by physical intervention, resulting in higher production costs and severely reduced flexibility. Compared to software radio, it defines a series of hardware and software technologies, including some or all of the radio operating functions, also known as physical layer processing, which can be modified in software by programmable processing techniques that allow in existing radio systems Add new wireless features and functions without requiring new hardware.
In the past military wireless communication equipment, it is necessary to provide continuous access technology independent of physical location. As a result, how many military vehicles must be loaded with many different devices for access to a single radio communication system, but the resulting large physical footprint is not conducive to system integration. Instead, software radio. It allows the physical communication platform to solve software up-conversion, mutual conversion between analog and digital signals, baseband signal processing, high-level protocols and applications, etc. Based on software-defined wireless communication protocols instead of hardware, it can effectively limit the physical space for Local access to available communication systems provides sufficient flexibility. In contrast, software-defined radio technology provides an efficient and relatively economical solution to this problem. It allows the use of software upgrades and can enhance the modes, frequency bands and capabilities of wireless devices. Software-defined radio defines a range of hardware and software technologies, including all radio operating technologies, also known as programmable processing technologies.
In the 1990s, the concept of software radio emerged to accommodate various digital wireless communication standards. At the time, each system had different requirements for its phones. Phones between different systems cannot be connected. In order to solve this problem, the software radio scheme proposes to collect all air signals from 2mhz to 2000mhz, sample, quantify and convert them into digital signals for software processing, so as to be compatible with any wireless communication system with the support of software radio technology. The original intention of software-defined radio was to combine the various frequency bands and operating modes employed by the US Navy Radio and the Army, with a focus on providing an SDR-based solution.
In 1996, after the launch of radio systems on the ground and over the air, video data gradually laid the foundation for the software-defined radio business standard. In 2008, the scope of the system was narrowed to ground mobile radios based on software-defined marine, Army vehicles and Army helicopters. At the same time, it is mainly used for commercial software definition of cellular base stations, satellite communications, intelligent transportation system solutions and public safety.
