The transition from the age of electrical telephony to the current internet service provider (IP)-based networks have been mainly steady, if not rapid, from the first generation (1G) to the embryonic fifth-generation (5G) networks. Today, there is a great deal of discussion about “big data,” the internet is virtually omnipresent, and everything seems to have “smart” powers thanks to interesting technologies like cloud computing, machine-to-machine communication, and the digital revolution.
Throughout these eras, technology has progressed from very low data rates to extremely high rates of 1 terabit per second (Tbps), which is possibly achievable in 5G technology. The value of telecom can be measured from this statement that telecom is now a fundamental part of how our society communicates. We are nothing without telecommunications but a review analysis of telecom companies in terms of trends and development is necessary before choosing one.
2G – 3G
2G stands for Second-Generation wireless telephones, which were introduced in the early 1990s and are based on digital technology. In Finland, 2G was introduced in 1991. Text messages, image messaging, and MMS were all available on 2G. Both the transmitter and the receiver are safer with 2G and it was used in over 212 countries. GSM technology has been continually developed over the last 20 years to provide good infrastructure on the market.
Based on the original GSM system, new technologies have been developed, resulting in certain sophisticated systems known as 2.5 G systems. GPRS is a technology that allows current 2G networks to offer packet-based services while also increasing the data speeds available. The GPRS network evolved to EGPRS which gave rise to 2.75 G systems that have more features than 2.5 G including a three-fold increase in the capacity.
3G – 4G
The third development of cellular phone standards and technology, which succeeded 2G and came before 4G, is known as 3G. 3G technologies allow telecom companies to provide a broader choice of more modern clientele while also increasing network infrastructure through increased transmission rates. The benefits of 3G include improved audio and video streaming, many times faster data rates, video-conferencing capabilities, faster Web and WAP browsing. Then 3.5G and 3.75G come with upgraded and sophisticated person-to-person computing resources, such as mobile e-mail and real-time person-to-person gameplay, with greater and consistent bit rates.
4G – 5G
4G is a notion of web interconnection that is all about high-speed transmitting data, such as 0-100MBPS of either the server or the data receiver set traveling at a speed of 60 Kmph. The data transport rate is at least 1GBPS if the server and receiver are both stationary. If you have 4G, you may use any of the aforementioned technologies to access the internet while traveling from one location to another. 4G mobile technology is capable of downloading at a pace of 100Mbps for mobile access and 1GBps for local wireless access. A significant aspect of 4G mobile technology is the transmission of data packets by splitting the route into a small band for increased efficiency.
The introduction of 5G network technology will create a new generation of data phones. Various wireless technologies will be available as soon as possible on 5G mobile phones, and the interface should be easy to blend multiple streams from various techniques. For the crazy cell phone user, 5G technology provides excellent resolution. On our mobile phones, we may watch TV channels in HD quality without pause. Tablet PC will be the 5G mobile phone. Many integrated digital phones will develop.
Everyone is switching to more convenient internet-based calling (VoIP) rather than the old-fashioned landline, from private households to large corporations. This does not imply that fixed lines have vanished or become obsolete; rather, it is the outcome of users’ decisions to move to cellular networks and cloud storage.
