It ensures smooth handovers, incorporates security measures, and is often backward compatible, allowing for global acceptance and interoperability with other networks. What are the … Read more
To determine if your phone will work after the 3G shutdown, first, check your phone’s specifications to see if it supports 4G or 5G. Contact your carrier to confirm their network plans and compatibility with your device. Use online tools or visit a carrier store for additional guidance. If your phone isn’t compatible, consider upgrading … Read more
General Packet Radio Service (GPRS) is a 2G wireless communication technology that introduced packet-switched data transmission, offering more efficient and always-on connectivity compared to earlier circuit-switched networks. It improved data speeds, enabled efficient data billing based on volume, and laid the foundation for mobile internet access, email, and basic app usage. GPRS was globally adopted … Read more
GPRS offers two main types of services: packet-switched services, which provide an always-on, efficient data connection suitable for internet access and data applications, with billing based on data volume; and circuit-switched services, which allow for voice calls and compatibility with older networks, though they are less efficient for data compared to packet-switched services. What are … Read more
Time Division Multiple Access (TDMA) is advantageous due to its efficient use of bandwidth by dividing it into time slots, ensuring fairness among users, predictable access, low latency, ease of implementation, scalability, collision avoidance, support for Quality of Service (QoS), energy efficiency, and multiplexing capabilities, making it suitable for a wide range of communication systems. … Read more
Active antenna systems (AAS) in 5G are complex arrays with individual RF components, enabling dynamic beamforming, massive MIMO, and high performance, making them suitable for high-capacity scenarios but costly. In contrast, passive antenna systems are simpler and lack individual RF components, offering fixed radiation patterns and lower costs, making them suitable for straightforward coverage needs … Read more
Effective Isotropic Radiated Power (EIRP) is a measure of the radiated power by an antenna in a particular direction, accounting for both transmitter power and antenna gain. It’s essential for ensuring compliance with regulatory power limits in wireless communication systems and helps engineers select antennas for optimal signal strength and coverage. EIRP is expressed in … Read more
