Radio Frequency or RF is one of the most fundamental concepts in mobile communications. Our mobile phones communicate with the mobile network using radio waves that are also called RF waves. These radio waves are electromagnetic radiations that travel through the air at specific frequencies. The frequency of a radio wave is calculated by dividing […]

Mobile networks employ radio waves (RF waves) for all communication between the mobile network base station and the cell phone. The radio waves travel through the air at particular radio frequencies, and as the frequency of a radio wave goes up, the length of the wave goes down. It means lower frequencies have bigger wavelengths

eMBB, mMTC and uRLLC are terminologies that are frequently used in the context of 5G New Radio (NR) networks. These terminologies are often expressed through a triangle that represents the key building blocks for specifying requirements for 5G networks. eMBB (Enhanced Mobile Broadband), mMTC (massive Machine Type Communication) and uRLLC (Ultra-Reliable Low Latency Communication) are
What do eMBB, mMTC and uRLLC mean in 5G? Read More »
5G mobile networks are highly flexible, and they use a range of different technologies to adapt to the customers’ changing needs. One key technology within 5G New Radio (NR) networks is network slicing which allows them to use the same 5G network infrastructure to serve a wide range of use cases. Network slicing is a

If your mobile operator offers 4G services, you may already have used the 4G calling or VoLTE service on your LTE compatible mobile phone. VoLTE is a technology 4G LTE networks use to facilitate voice calls and text messages. VoLTE stands for Voice over LTE, and it is a managed-VoIP technology in 4G LTE networks
What is Voice over LTE or VoLTE on my 4G LTE phone? Read More »
4G LTE networks use the Orthogonal Frequency Division Multiple Access technique (OFDMA) for the air interface to enable wireless connectivity between the cell phone and the base station. OFDMA uses the multicarrier modulation scheme (MCM), which involves a large number of sub-carriers to transmit data by breaking it down into smaller chunks and then transmitting
What modulation technique is used in 4G LTE networks? Read More »
OFDM, OFDMA and SC-FDMA are technologies that enable radio communication between a mobile phone and the 4G LTE mobile network. OFDM stands for Orthogonal Frequency Division Multiplexing, OFDMA stands for Orthogonal Frequency Division Multiple Access, and SC-FDMA stands for Single Carrier Frequency Division Multiple Access. OFDM is the primary transmission scheme in 4G LTE networks

The term Gigabit LTE is often used in the context of 5G mobile networks, and it can be hard to differentiate it from 5G if you are not familiar with the cellular technologies that enable 4G and 5G. 5G stands for the fifth generation of mobile networks, whereas Gigabit LTE is linked to fourth-generation (4G)
Gigabit LTE vs 5G – Is Gigabit LTE part of 4G LTE or 5G NR? Read More »
LTE or Long Term Evolution is the most widely deployed and adopted cellular technology today. LTE represents the fourth generation of mobile networks, and LTE Advanced is one of the key enhancements added to LTE to improve the data rates considerably. LTE or 4G LTE is the fourth generation of mobile networks that uses the
