It is based on the technology known as global system for mobile communication or in short we can say GSM. Keeping up the trend of a new mobile generation every decade, fourth generation (4G) of mobile communication was introduced in 2011. Second Generation (2G) technology was launched in the year 1991 in Finland. The intermediate generation, 3.5G grouped together dissimilar mobile telephony and data technologies and paved way for the next generation of mobile communication. Trained personnel required for infrastructure set up.High infrastructure costs like licensing fees and mobile towers According to the 3rd generation partnership project (3GPP) 1, 2, 5G networks should support three major families of applications, including enhanced mobile broadband (eMBB) 1, 2 massive machine type communications (mMTC) 1, 2 and ultra-reliable and low-latency communications (URLLC) 1, 2.Here are some downsides of 3G technology − Running web based applications like video conferencing, multimedia e-mails, etc.įast and easy transfer of audio and video filesĮvery coin has two sides. Some of the characteristics of this generation are − Third generation (3G) of mobile telephony began with the start of the new millennium and offered major advancement over previous generations. 2G with GPRS is also referred as 2.5G, a step short of next mobile generation. When GPRS technology was introduced, it enabled web browsing, e-mail services and fast upload/download speeds. Some prominent characteristics of 2G communication are − It was launched in Finland in 1991 and used GSM technology. Some characteristics of 1G communication are −ĢG refers to the second generation of mobile telephony which used digital signals for the first time. It was introduced in the US in early 1980s and designed exclusively for voice communication. 1G TechnologyġG refers to the first generation of wireless mobile communication where analog signals were used to transmit data. Here we will discuss the basic features of these generations that differentiate it from the previous generations. Be it technology, protocols, services offered or speed, the changes in mobile telephony have been recorded as generation of mobile communication. Since the introduction of first commercial mobile phone in 1983 by Motorola, mobile technology has come a long way.
