The transition to 5G has been rocky. To facilitate faster and more reliable digital communication, radio-spectrum regulators have approved the operation of 5G transmitters and receivers within various wavelength bands in the 1-25 GHz range, according to research by Physics Today.
Radio waves in the L (~1–2GHz) and C (~4–8GHz) bands travel long distances but have limited bandwidth. Those in the 24GHz band don’t travel as far but have the wide bandwidth needed to increase data-transfer rates by an order of magnitude, according to Physics Today associate editor Alex Lopatka.
The problem, Lopatka identifies, is that radio spectrum is already widely-used, and 5G licenses granted in the US have approved the use of wavelengths that are close to those used for essential scientific and technical applications.
He says technologies threatened are satellites that measure water vapour, altimeters that record an airplane’s vertical position, and instruments that the private and public sector rely on for GPS navigation.
The neighbouring chunks of spectrum are close enough that the 5G signal power may bleed into nearby bands and cause signal interference, especially when 5G activity ramps up, he added.

PROMOTE YOUR WEBINAR ON ITWIRE
It’s all about Webinars.
Marketing budgets are now focused on Webinars combined with Lead Generation.
If you wish to promote a Webinar we recommend at least a 3 to 4 week campaign prior to your event.
The iTWire campaign will include extensive adverts on our News Site itwire.com and prominent Newsletter promotion https://itwire.com/itwire-update.html and Promotional News & Editorial. Plus a video interview of the key speaker on iTWire TV https://www.youtube.com/c/iTWireTV/videos which will be used in Promotional Posts on the iTWire Home Page.
Now we are coming out of Lockdown iTWire will be focussed to assisting with your webinars and campaigns and assistance via part payments and extended terms, a Webinar Business Booster Pack and other supportive programs. We can also create your adverts and written content plus coordinate your video interview.
We look forward to discussing your campaign goals with you. Please click the button below.
