The future of next generation 5g wireless communication

Wireless communication is the fastest developing field in the field of communication , The most active area of Technology . Wireless communication is a kind of communication without using any connection ( Such as wire , Cable or any physical medium ) How to transfer information from one point to another .



 The next generation 5G The future of wireless communication


Usually , In a communication system , Information is sent from the transmitter to a receiver placed at a limited distance . With wireless communication , The transmitter and receiver can be placed within a few meters ( Such as TV remote control ) Thousands of kilometers ( Satellite communications ) Anywhere in between .


We live in a world of communication and wireless communication , Especially the key parts of our lives . In our daily life , Some common wireless communication systems include : mobile phone ,GPS Receiver , The remote control , Bluetooth audio and Wi-Fi etc. .



 The next generation 5G The future of wireless communication


The communication system can be wired or wireless , The medium used for communication may be guided or non guided . In wired communications , Media is a physical path , For example, coaxial cable , Twisted pair cables, fiber optic links, etc , It guides the signal from one point to another .


This type of media is called the leading media Guided Medium. On the other hand , Wireless communication does not require any physical medium , But it can transmit signals through space . Since space allows only signal transmission without any guidance , Therefore, the medium used in wireless communication is called non bootstrap medium .


If there is no physical medium , So how does wireless communication send signals ? Even if cables are not used in wireless communications , The transmission and reception of signals can also be accomplished through the antenna .


An antenna is an electrical device that converts electromagnetic waves into radio signals , vice versa . These electromagnetic waves travel through space . therefore , The transmitter and receiver are made up of antennas .


The future development path


Now ,5G Business is in its second year , The leaders in the wireless industry have been interested in 5G The future of wireless networks has been coveted for a long time . 5G Americas Announced the release of 《 2020 Years later, mobile communications – 5G The next generation G Evolution of 》 white paper , The white paper details the global work of a number of academic and industry organizations , And put forward 5G towards “ The next generation ” Potential use cases and technologies essential to evolution .


5G Americas President Chris Pearson Express :“ 5G Now in the second inning of nine innings , Its future innovation path is huge . however , The mobile wireless industry is undergoing transformation . Although the epidemic has not yet been eliminated , But the digital industry is still changing , therefore , It is necessary to study the next generation mobile cellular wireless technology .”


although 5G It's still early in the life cycle , But through 3GPP Standards are constantly updated , It's important for the Internet , Architecture , These enhancements in technology and standards will penetrate into 3GPP Release 17 And higher . however , It is expected that in the next few years , international telecommunications union (ITU) The upcoming International Mobile Telecommunications 2030(IMT-2030) Will outline the requirements for next generation mobile wireless .


Early ideas around the next generation of wireless use cases may involve tactile or tactile communication , High resolution terahertz spectrum for imaging and sensing uses , Network physical systems in manufacturing and scenarios for enhanced public security and national security applications .


This 5G The white paper covers three main themes :


? Looking back at North America and the world 5G Other activities

? How communication will be in 2020 Changes have taken place since the 1990s , It includes several use cases

? How North America can establish and maintain a leading position in the future communication standards


AT&T Assistant Vice President of standards and Industry Alliance and head of the white paper development working group Brian Daly Express :“ Many are identified as 'Next G' and '6G' The project is going on all over the world ,5G Americas And made some contributions . In the U.S. , Business entities , Government and academic institutions need to be at the forefront of these next-generation developments .”


T-Mobile Director of industry forum and relations Mark Lipford Comment on :“ 5G It will bring more options for business innovation , But in the next decade , consider ITU by IMT The vision and goals set are also very important .”
