How Do We Increase The Wireless System Capacity?
The Answer is in “Shannon–Hartley theorem“ Shannon–Hartley theorem tells the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise. C: is the channel capacity in bits per second. B: is the channel’s bandwidth in bits per second, which defines the maximum amount […]
2G and 3G Shut down Status – 2023
More pressure now on all MNOs to improve their spectrum utilization and resource efficiency to the maximum to cover all upcoming use cases that need different QoS and requirements. One of the most promising solutions is to shut down the legacy network technologies 2G and/or 3G to utilize their spectrum towards 4G or/and 5G. As […]

When should MNOs shut down their 2G and 3G Networks?
Many of my friends asked me why MNOs (Mobile Network Operators) didn’t switch-off legacy networks like 2G and 3G till now. Yes, this is a good question specially day-by-day I am talking about the benefits and the power of 5G. With the smartphone revolution and the rapid growth in wireless data services, operators worldwide are […]
