What is 5G and in what ways can we contribute to its development?

5th generation mobile networks or 5th generation wireless systems, abbreviated as 5G or 5G technology)

It is the latest generation of cellular mobile communication technology, which is an extension of 4G (LTE-A, WiMax), 3G (UMTS, LTE), and 2G (GSM) systems. The performance goals of 5G are high data rates, reduced latency, energy savings, cost reduction, increased system capacity, and large-scale device connectivity. The first phase of the 5G specification in Release 15 was designed to accommodate early commercial deployments. The second phase of Release 16 will be completed in April 2020 and submitted as a candidate for IMT-2020 technology to the International Telecommunication Union (ITU). The ITU IMT-2020 specification requires a speed of up to 20 Gbit/s, which can achieve wide channel bandwidth and large capacity MIMO

ITU is the International Telecommunication Union

The International Telecommunication Union is a United Nations agency responsible for information and communication technology affairs, allocating and managing global radio spectrum and satellite orbit resources, developing global telecommunications standards, providing telecommunications assistance to developing countries, and promoting global telecommunications development.

It has a research department:

(1) Telecommunication Standardization Sector (ITU-T)

At present, there are 10 research groups mainly active in the telecommunications standardization department.

SG2: Operational issues related to business provision and telecommunications management;

SG3: tariff and settlement principles including relevant telecommunications economic and policy issues;

SG5: Environment and Climate Change;

SG9: Television and sound transmission, as well as integrated broadband wired network;

SG11: Signaling requirements, protocols, and testing specifications;

SG12: Performance, Quality of Service (QoS), and Quality of Experience (QoE);

SG13: Future networks including mobile and next-generation networks (NGN);

SG15: Optical transmission network and access network infrastructure;

SG16: Multimedia Encoding, Systems, and Applications;

SG17: Safety.

（2) Radio Communication Department (ITU-R)

At present, there are six research groups mainly active in the radio communication department.

SG1: Spectrum Management;

SG3: Radio wave propagation;

SG4: Satellite services;

SG5: Ground Operations;

SG6: Broadcasting services;

SG7: Scientific Business.

(3) Telecommunications Development Department (ITU-D)

The Telecommunications Development Department was formed by the merger of the former Telecommunications Development Bureau (BDT) and Telecommunications Development Center (CDT). Its responsibility is to encourage developing countries to participate in the research work of the International Telecommunication Union (ITU), organize technical seminars to enable developing countries to understand the work of the ITU and apply its research results as soon as possible; Encourage international cooperation, provide technical assistance to developing countries, and build and improve communication networks in developing countries.

Currently, ITU-D has established two research groups.

SG1: Research on Telecommunications Development Policies and Strategies;

SG2: Development and management of telecommunications services, networks, and ICT applications.

Where can we assist? Starting from the front-end, we use 15KP48CA and 15KP58CA on macro base stations

A macro base station refers to a wireless signal transmission base station of a communication operator. The coverage distance of a macro base station is large, generally around 35km, and it is suitable for areas with scattered traffic in the suburbs. It has omnidirectional coverage and high power. A base station is a public mobile communication base station. It is an interface device for mobile devices to access the Internet, and is also a form of radio station. It refers to a radio transceiver station that transmits information between mobile phone terminals and mobile communication switching centers in a certain radio coverage area. The main function of a base station is to provide wireless coverage, that is, to achieve wireless signal transmission between wired communication networks and wireless terminals. )

Where can we assist? Starting from the backend, we use 5 on micro base stations KP48CA、5KP58CA、5.0SMCJ48CA、5.0SMCJ58CA、5.0SMCJ60CA、5.0SMCJ64CA、5.0SMCJ75CA、5.0SMCJ85CA、5.0SMCJ90CA、5.0SMCJ100CA、5.0SMCJ90A

In terms of terminal equipment, such as WIFE-6, CPE, and these customers will be our key strategic clients
