Outdoor Wireless Networks: Must Know Facts

Catalina Joseph, Telecom Tech Outlook | Friday, April 02, 2021

Over the next 18 months, 100 MHz of contiguous mid-band spectrum in the 3450-3550 MHz band is expected to be made available for 5G in addition to CBRS and C-band.

Fremont, CA: The telecommunications industry looks forward to creating a world where connectivity is genuinely pervasive and available for everyone as an eventful 2020 draws to a close. Operators will begin to accelerate their introduction of 5G networks across the globe in 2021 to help achieve this goal, as policymakers will clear extra spectrum to handle more users and data. At the same time, as Open RAN deployments gain severe momentum and usher in a new wave of goods and revolutionary technologies, disaggregation of the RAN will begin.

Here are three trends of outdoor wireless networks:

Clearing the spectrum

To create a world in which communication is genuinely pervasive and open to everyone, clearing the spectrum to accommodate more users and data is necessary. It is predicted that policymakers will begin to take the initiative to remove the spectrum for 5G and beyond in 2021. In 2021, operators will begin to map out locations, with the first use of C-band expected to commence in metropolitan areas in late 2021 or early 2022. Until June 2023, C-band will not be available to MNOs and their subscribers for several suburban areas. Over the next 18 months, 100 MHz of contiguous mid-band spectrum in the 3450-3550 MHz band is expected to be made available for 5G in addition to CBRS and C-band.

Open RAN

Open RAN implementations will gain serious momentum in 2021 and usher in a new generation of creative goods and technology. This is because inside and between the various subcomponents of the RAN: the radio, hardware, or baseband device and software, Open RAN supports completely open and interoperable interfaces. This paradigm drives innovation by promoting the growth of an extended supply ecosystem through open interfaces and product hardware platforms while reducing capital costs and single vendor’ lock-in. ‘

5G and massive MIMO

To provide more network power and broader coverage, Massive MIMO dramatically improves spectral performance. However, operators will have to decide if the increased costs and real-world power requirements associated with active MIMO deployments are warranted or if the configuration of the passive antennae will be appropriate. Indeed, initial major higher-end MIMO installations in some geographic locations have allegedly failed to keep up with power requirements and are regularly shut down to conserve energy for hours at a time.
