Microwave Tech - Three major development directions:high frequency and high sspeed board wireless networks

High Frequency and High Speed board is the main material in telecommunication industry the telecommunications industry is looking forward to building a future in which co-signers are ubiquitous and truly connected to each other. To successfully achieve this goal, operators will continue to accelerate the rollout and expansion of 5G networks worldwide in 2021. At the same time, governments will further overhaul more spectrum to accommodate more users and numbers. As open web architectures gain more and more attention, new generation products and innovative technologies are being developed, the de-polymerization of RAN is likely to unfold to some extent and continue for years to come .Here are three major trends we see:

5G Network & Massive MIMO

Although COVED-19 and the resulting shutdown have had a certain impact on 5G network deployment in some countries and regions around the world, 5G deployment will continue to progress rapidly with the launch of 5G smart phones such as Samsung Galaxy S20 and Fruit iPhone 12. In order to support these new facilities, operators will need to focus on pragmatic 5G network implementations, assessing beforehand which deployments will actually benefit from the bandwidth benefits of Massive MIMO (multiple input/multiple output), as well as the associated cost, resource and power requirements.

Massive MIMO significantly increases the spectral rate, providing higher network volume and more stereoscopic coverage. However, the operator will need to confirm whether the deployment costs associated with active Massive MIMO, the cost of the set and the actual power consumption requirements are justified, or whether the relatively less efficient but higher performance cost ratio of the passive receiving antenna (8T8R or 4T4R) is sufficient. In fact, high-order Massive MIMO is reported to be deployed at the beginning of a period in some geographic locations to meet power consumption needs, which typically require shutting down for several hours at a time during off-peak hours to save power consumption.

High-Speed Wireless Network clean up the spectrum

Cleansing up the spectrum to accommodate more users and more values is crucial to building a truly connected future where co-signatories are everywhere and everyone has access to them. However, most of the low - and mid-band spectrum around the world has long been used by military and economic satellite operators, wireless Internet service providers (WISPs) and other utilities. The reallocation or sharing of these bands for the next generation of wireless economic activity services generally requires the active participation and planning of existing users and government regulatory agencies, as well as extensive consultation around how to mitigate the impact on existing services.

Despite the challenges outlined above, we expect governments to take further aggressive steps in 2021 to overhaul spectrum resources for 5G and beyond. In the United States, for example, the Federal Communications Commission (FCC) recently completed a PAL auction for the 3.5GHz band and is preparing to proceed with an auction for the 280MHz mid-band (C-band) spectrum, making the 3.7-3.98GHz range of the band available for flexible use (including 5G). With respect to the latter, operators will continue to expand their sites through 2021, starting with C-band in urban areas by late 2021 or 2022. For many rural areas, mobile-network operators and their subscribers will be able to use C-band after June 2023. In addition to the CBRS and C bands, the U.S. also plans to use 100 MHz of the 3450-3550 MHz mid-band spectrum for 5G over the next 18 months.

In Europe, the European Union (EU) is pushing to open up new bands and bandwidth for 5G across the EU. The band covers: 700MHz to 30MHz, 3.5GHz to 400MHz and 26GHz to 3GHz. Similarly, Europa carriers already use 1800MHz or 2100MHz for high-speed wireless network under the Dynamic Spectrum Sharing Standard (DSS) format. In the Middle East and Africa, spectrum has been allocated to multiple operators in the C-band, covering the United Arab Emirates, Saudi Arabia, Qatar, Oman and southern Africa.

High-Speed Wireless Network open RAN interface

The open RAN interface provides many new advantages for mobile operators. First, the open RAN interface can help operators reduce costs through the commercial block (COTS) disposal facilities of baseband units (BBUs) and the generic platetization of RU hardware. In addition to this, the open RAN interface enables the separation and universalization of software parts from proprietary hardware systems, thus facilitating the creation and rapid deployment of new services and operational solutions. As mentioned above, as more new suppliers enter the market, open RAN interfaces can foster a stronger supply chain lifestyle system. Because of this, further progress in the depoly merization of RAN will certainly continue in 2021, with the deployment of open RAN interfaces and a large number of concerns and therefore further generation of products and innovations (such as more urgent integration of radio frequency and receiving antennas).

In addition, the open RAN interface will continue to play a critical role in accelerating the deployment of 5G infrastructure after successfully enabling extensive interoperability between facilities. US carrier Dish has voted to opt for the open RAN interface for 5G deployment in the US, promising to cover 70% of the population through its 5G network by June 2023. In Toyo, Rakuten's 5G network will be based on the open RAN interface architecture, allowing it to mix and match the technologies most appropriate for users as it sees fit. At the same time, Vodafone (Vodafone) is clearly acknowledged, and plan to start working in Europa, USA and Africa open RAN interface experiment, beginning of the experiment is expected to focus on 2 g, 3 g and 4 g mobile phone and numerical services, the future will be involved in 5 g's other Vodafone open RAN interface to do an experiment. Notably, Vodafone became the first UK mobile operator to start using an open RAN interface site. Operators in China are also considering the use of open RAN in indoor covered small cell stations to enhance the indoor application of 5G, which is likely to start in 2021.

High-Speed Wireless Network build a better future

As 2020 draws to a close, the telecom industry looks forward to 2021 and to building a better future where connectivity is truly ubiquitous. Although COVID-19 has had a small impact on the deployment of 5G networks worldwide, 5G deployment will continue to advance rapidly through 2021 as more 5G Smart phones and terminals are rolled out. In order to support these new facilities, mobile network operators need to assess which deployments would be best for active Massive MIMO deployments to realistically focus on the efficient implementation of 5G networks. Governments around the world will overhaul more spectrum to accommodate more users and numbers, and the progress and deployment of open RAN interfaces will receive increasing attention, hastening the emergence of a new generation of products and accelerating the rollout of 5G network to the ground.
