A: 5G is based on OFDM (Orthogonal frequency-division multiplexing) , a method of modulating a digital signal across several different channels to reduce interference. 5G uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.
Read moreWhat encryption does 5G use?
Data traffic within the 5G infrastructure is protected by state-of-the-art encryption . The devices and the network authenticate each other using integrity-protected signaling. This ensures that if a single component is compromised, the other components remain protected.
Read moreWhich 3GPP releases cover 5G?
After initial delivery in late 2017 of ‘Non-Stand-Alone’ (NSA) NR new radio specifications for 5G, much effort focused in 2018 on timely completion of 3GPP Release 15 – the first full set of 5G standards – and on work to pass the first milestones for the 3GPP submission towards IMT-2020.
Read moreWhat are the 3GPP standards?
The term “3GPP specification” covers all GSM (including GPRS and EDGE), W-CDMA (including HSPA), LTE (including LTE-Advanced and LTE-Advanced Pro) and 5G specifications . Revised versions of many of these specifications are produced up to four times a year following the quarterly TSG plenary meetings.
Read moreWhat does 3GPP do for 5G?
3GPP is a collaborative activity between well-established regional standard organizations. The goal is to develop and maintain global technical specifications . This is to make sure that network equipment and handset manufacturers can develop products that are interoperable all over the world.
