Why 4G LTE Networks Use OFDM And OFDMA techniques?

As technical as they may sound, OFDM and OFDMA are gaining popularity both in the mobile and fixed wireless industries. OFDM – Orthogonal Frequency Division Multiplexing and OFDMA – Orthogonal Frequency Division Multiple Access technologies are used in modern wireless networks, including 4G LTE, 5G NR, WiMAX and WiFi6. Before dividing into the ‘Orthogonal’ and …

Is 5G NR different from Gigabit LTE, LTE-Advanced and LTE-A Pro networks?

The 5G technology has already arrived in many countries across the world. Whenever a new technology is about to enter, some inter-related terminologies and buzzwords either follow or come to the surface even before the new technology is available. This happened at the start of 4G LTE and is now happening again with 5G. The …

How 4G-LTE differs from LTE-Advanced and LTE-Advanced Pro?

The first publicly available LTE mobile network was launched in the Scandinavian cities of Stockholm and Oslo in 2009. That was over ten years ago, and a lot has happened since then in the ever-changing world of mobile communications. Today, the LTE technology has become synonymous with 4G and vice versa. We frequently see terminologies …

What are standalone (SA) and non-standalone (NSA) 5G NR mobile networks?

For many people, 5G is probably just another generation of mobile networks with some additional features. Let’s face it; we see a new generation of mobile networks nearly every ten years, and now that we already get reliable mobile broadband speeds with 4G, do we really need yet another upgrade? It is not really a …
