It refers to using 5G as an evolution to 4G LTE mobile broadband services with faster connections, higher throughput, and more capacity.

5g technology features software#
3GPP defines any system using “5G NR” (5G New Radio) software as “5G”, a definition that came into general use by late 2018. The peak bit rate is further improved by smart antenna arrays for multiple-input multiple-output (MIMO) communications.Īnd now for 5G, the standard organizations already established the requirements to consider a system 5G. Since 4G is based on IP telephony, the 3G spread spectrum was abandoned and replaced by OFDM multicarrier transmission and other frequency-domain equalization (FDE) schemes, making it possible to transfer very high bit rates despite extensive multipath radio propagation (echoes). Improved versions of both the systems with improved numbers, which were matching 4G requirements were later released 20. However, service providers marketed them as 4G to sell their services. Mobile WiMax and LTE were released as successors of 3G, but since they were not able to match the numbers set by IMT-A. It set the peak speed requirements for 4G service at 100 megabits per second (Mbps) for high mobility communication (such as from trains and cars) and 1 gigabit per second (Gbps) for low mobility communication (such as pedestrians and stationary users). In March 2008, the International Telecommunications Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards and named it International Mobile Telecommunications Advanced (IMT-Advanced) specification.

The third generation or 3G networks were introduced in 1998 as 3GPP was established to develop a specification for a 3G mobile phone system based on the 2G GSM system, within the scope of the International Telecommunication Union’s International Mobile Telecommunications-2000 (IMT-2000).Īnother 3GPP2 standard organization was formed to develop the competing 3G system based on CDMA.

While in North America, they mostly used Code Division Multiple Access (CDMA), another 2G standard proposed by Qualcomm, and launched in 1995. It was first deployed in Finland in 1991. GSM is one of the most popular standards developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks. It used the analog service called Advanced Mobile Phone Service (AMPS) on which 1G or the first generation of mobile communication was based.ġG was introduced in 1979 and continued until being replaced by 2G or the second generation of mobile communication that’s based on digital radio signals. It was the first mobile call made (in April 1973) using a base station of 900 MHz and a prototype which was later known as the world’s first commercial cell phone. “I’m ringing you just to see if my call sounds good at your end,’ or something to that effect”, said Martin Cooper, a Motorola employee, during a call that commenced the mobile phone era.
