C-band (3.4 GHz to 3.8 GHz) and 2.6 GHz frequencies are widely used by telecom operators in the Middle East, Africa and Europe for 5G networks, Nokia said regional CTO.
"In the US It started with the millimeter wave (between 24 GHz and 86 GHz), but in the Middle East, Africa and Europe it is the frequencies C-band and 2.6 GHz, which provide wider coverage and coverage offer indoors, and it's better in the C band when compared to mmwave, "said Aji Ed, CTO at Nokia Middle East and Africa, opposite TechRadar Middle East .
Nokia has 48 5G commercial contracts worldwide, and 1
Of the 48 contracts, around 25% came from the Middle East and Africa.
With the mmwave He said the advantage is that it has much more spectrum than the C band.
"An operator can reach up to 400 MHz in the mm-wave compared to 200 MHz in the C-band, but the disadvantage is that the coverage will be very limited, up to 100 meters. Without obstacles, the range of mmwave can reach up to 400 meters, "he said.
With the C-band, it can average up to 1.5 km, with obstacles such as tall buildings but up to 400 meters C-band can be up to 500 meters high.
Asked if mmwave is critical for 5G, he said that everything depends on the use cases.
Hottest discussion topic.
"C-band may have a good spectrum for 5G compared to 4G LTE, but if you look at specific scenarios in hotspots like stadiums and major events where much higher throughput or uploads are required in a limited coverage area, then mmwave very important. "Ed said.
New frequency bands for 5G use will be the hottest topic of discussion when International Telecommunications Union (ITU) members meet at the 2019 World Radio Communication Conference (WRC) in Egypt.
The WRC will take place between October 28th to 22nd, and will be organized by the ITU to review and revise e radio regulations.
Many operators around the world are beaming 5G over the existing 4G infrastructure, as the final frequency for 5G is not yet fixed. Non-autonomous means transferring 5G over the existing 4G infrastructure, and autonomously means transferring 5G over a specific spectrum.
The UAE's Telecommunications Regulations Authority (TRA) has deployed the C-band (where satellite operators also use these frequencies) for 5G deployments in the United Arab Emirates.
Tareq Al Awadi, Executive Director of Frequency Management at TRA and Chairman of the Arab Spectrum Management Group, told TechRadar Middle East recently that the emphasis on ITU will be on mmwave alongside the C band.
Some countries in the Arab world have problems at 3.4 GHz and 3.8 GHz, while some countries have already started at 700 MHz for lower bandwidth and some countries, including the Arab countries, are also interested in the L band (1) – 2 GHz).
Telecom operators in the UAE – Etisalat and Du – work with 5 G in the C-band and at 2.6 GHz.
According to Ed, mmwave will not be available for launch in the region and Arab countries do not focus on it now, but in the future.
