Can Microwave be the right backhaul technology for 5G?
November 20, 2023

I read many papers during this year about the capabilities of microwave as a backhaul technology of 5G. I see also some claims that fiber is a mandatory technology for #5G backhauling due to the huge amount of data growth with the wider bandwidth in the spectrum in Sub-6GHz and mmWave which can exceed the 1Gpbs […]

Fixed Wireless Access Is ‘First Killer 5G Application’
November 1, 2023

Fixed Wireless Access (FWA), a wireless link that provides connectivity to objects that are stationary or nomadic, will receive a boost thanks to improved 5G capabilities. The first 5G use case we highlight is FWA. The demand for high-speed broadband connectivity continues to grow exponentially, driven by the increasing reliance on digital technologies and the […]

5G Core Network Functions (NFs)
October 28, 2023

The 5GC architecture relies on a “Service-Based Architecture” (SBA) framework, where the architecture elements are defined in terms of “Network Functions” (NFs) rather than by “traditional” Network Entities. Via interfaces of a common framework, any given NF offers its services to all the other authorized NFs and/or to any “consumers” that are permitted to make […]

Move your RAN Knowledge to Transport Experience
October 8, 2023

My telecom journey started 13 years ago in the access domain which more specifically we can call it RAN or Radio Access Network which mainly focuses is more towards Air interfaces including spectrum, RF elements, site components, RAN features, interfaces, protocols, …etc. However, in the last 7 years, I have seen a huge shift from […]

Power Consumption of 4G and 5G Networks
October 5, 2023

The fact of Sustainability in mobile networks starts with power reduction and meeting net-zero goals, and as we know wireless networks consume large amounts of resources, from electricity to raw materials. 📃 GSMA Intelligence published a report looking at network energy efficiency. It found that the RAN consumes 73% of the energy network operators use. 📃 Also, […]

3G Shutdown is a MUST step for all MNOs!
September 21, 2023

This is not the first time we discussed the 3G Shutdown or Sunset topic, however, this time the numbers will talk 🙂 All UK mobile network operators have committed to closing their 3G networks. Vodafone UK, like EE, is planning to switch off its 3G network in early 2024. Three UK is planning to sunset […]

Is Microwave Oven Safe?
September 7, 2023

If you’re a Telecom Engineer and Hungry, this article is for you 🙂 During my discussion with my non-telecom friend, he was asking about the Telecom tower’s radiation and how it’s radiating the signals to the mobile equipment and then asked about the radiation of MicrowaveOven! Here, I remembered when I searched for this topic 13 […]
