Huawei Announces Next-Generation Enterprise Wireless Communication Solution at CeBIT2017

【Global Internet Reporter, Hannover, China】 On March 22, 2017, Huawei's CeBIT 2017 in Hannover, Germany, announced a new generation of wireless communications solutions for enterprises, announcing that it will bring corporate wireless communications into the 2.0 era. The new generation of enterprise wireless communication has three main characteristics: all-round (a set of systems supporting voice/video/intercom/monitoring/Internet of things, etc.), high reliability (industrial grade) and availability everywhere (based on licensed spectrum also May be based on unlicensed spectrum). Communication is the basis of digital transformation of enterprises, and all-round, high-reliability, ubiquitous next-generation enterprise wireless communications will surely become the accelerator for digital transformation of enterprises. It is estimated that by 2020, there will be nearly 7 billion connections from companies in the world.

The 1.0 Era to Improve

Talking about wireless communication, we must first talk about spectrum. Spectrum is the basis of wireless communications and is divided into licensed spectrum and unlicensed spectrum (such as ISM Band). Many companies have the need to build their own wireless private networks, but it is often difficult for a single company to obtain licensed spectrum. Even in the huge industries involving the national economy and the people's livelihood, such as electricity and railway transportation, the dedicated spectrum resources that can be applied for are very limited, and the bandwidth is often not more than 10 MHz. With the digital transformation of enterprises, the demand for communications has become more and more abundant. From simple voice communications to data, video, Internet of Things, industrial control, cloud... The demand for bandwidth is also increasing. This makes many companies have to consider using unlicensed spectrum at the same time, because the license-free ISM Band such as 2.4GHz, 5.8GHz add up to hundreds of MHz. In the 1.0 era, WiFi that can use the unlicensed spectrum is the WiFi. The reliability, stability, mobility, and other aspects of the WiFi cannot be fully satisfied by the enterprise. However, there is no better technology choice for the enterprise wireless private network.

Enterprise wireless communication enters the 2.0 era

"Now, all these problems will become the past. Huawei will bring enterprise wireless communications into the 2.0 era!" Huawei said at the press conference: "3GPP is the largest standards organization for global mobile communications and has a strong industrial chain. Under the coordination, cellular mobile communications have grown to 4.5G and are moving towards 5G. Huawei uses technologies based on 3GPP's global unified wireless communications standards to apply both to licensed spectrum and unlicensed spectrum, and to make cellular mobile communications highly reliable and versatile. Advantages Combine the advantages of unlicensed spectrum and availability of spectrum everywhere, and create an eLTE industry solution based on 4.5G technology, broadband, narrowband, and licensed, unlicensed spectrum convergence to support enterprise customers to build enterprise wireless, highly reliable, and readily available enterprise wireless. Communication system: A system supports both narrow-band and wide-band communication, supporting both human and object communication, supporting both communication with a particularly low time delay and communication with a large number of connections, and at the same time meeting the needs of enterprise production. Operations, management, office, and other communication needs accelerate the digitization of enterprises Type. "

High reliability – Stable and reliable is the key requirement of wireless communication for enterprise customers, but how can it be realized on the unlicensed spectrum? 2.0's enterprise wireless solutions take full advantage of advanced technologies in cellular communications to further incorporate advanced interference detection and avoidance algorithms, so that at the same time when a large number of users are online, they can still reasonably use wireless resources to ensure performance. At the same time, 99.999% industrial-grade reliability is provided through multi-level redundant backup of equipment and systems to ensure the long-term and stable operation of the system.

Omnipotence - From wireless voice calls to multimedia communications, from wireless video surveillance to mass sensor data acquisition, from real-time dispatching to robotic remote control, and in the face of communications needs of various applications, in the past companies deployed multiple different technology types of networks. The ensuing problem is that it is difficult to share data between networks and network construction and maintenance costs are high. In the 4.5G cellular communications and the future 5G, it is the consensus of the industry that a system meets various communication requirements. The Huawei Enterprise Wireless 2.0 solution migrates 4.5G technology to enterprise wireless communication scenarios, providing wireless broadband and low-power wide-area object-connected services through a unified network to meet the bearer requirements of data, IoT, voice, and location services. , to provide all-round corporate wireless communications, to achieve corporate people, people and things, things and things in full connection.

Although the 2.0 solution has not yet been sold globally, it has been successfully commercialized and tested at Shanghai Yangshan Port, one of the world's largest ports. The verification shows that the communication reliability of the solution reaches 99.999%, which can help the port to improve its work efficiency by 30%. The validation in the power industry has also been successful, achieving 100% of the automatic distribution of monitored systems online. The 2.0 solution has been successfully verified and can be applied to various applications such as real-time acquisition of distribution automation data, AMI smart meters, wireless video surveillance, wireless communication of urban rail vehicles, and data collection of mass sensors in smart cities.

Corporate Wireless Communications 2.0 - Moving to Large-Scale Business

The 2.0 solution will begin global sales in July of 17th. It is expected that it will be widely applied in fields such as electric energy, smart manufacturing parks, and smart cities, and will be expanded to various industries. It is estimated that by 2020, there will be nearly 7 billion connections from companies in the world. Just as cellular mobile communications have greatly changed people's lifestyles, I believe that the company's wireless 2.0 solution will greatly change the way companies work, as an accelerator to help companies in various industries achieve digital transformation!

CeBIT 2017 was held from March 20th to 24th at the Hanover Exhibition Center in Germany. The Huawei booth is located in Hall 2, Stand C30.
