telecom trainingTELECOMMUNICATION, no doubt is one of the fastest growing industries not only in India… but also all around the globe. As cellular phones have replaced outdated wireline systems, therefore there is an explosive growth in the field of   communication that suggests a bright and a stupendous future for engineers in the field of Telecom.

As compared to other countries, In India, there are about 920 million telecom subs cribers in which 12 million subscribers are added every month. Whereas in the entire Middle East and Saudi Arabia have around 24 million subscribers. This shows that India is the best option to pursue your career in Telecom industry.

Wireless communication has undergone a tremendous enlargement and growth in technology with the potential to provide high speed, high quality information exchange between devices which are anywhere in the world. There is a wide and remarkable history of mobile communication technology. Wireless technology has developed from 1st generation (1G) to 4th generation (4G), and now even 5G is coming in the picture.

Basically 1G is the analog cellular mobile communication network in the time period of middle of 1970s to the middle of 1980s. The best examples of 1G mobile communication systems are AMPS, TACS, NMT etc. But in 1G, the frequency spectrum was not utilized completely. In fact there were limited types of services in 1G and most important of all, the speed of data services were quite low. So, due to these typical drawbacks of first generation technology, the digital mobile communication technologies emerged, which completely replaced the analog communication technology. And then in 1990s, finally 2G came into being whose technologies are GSM and IS-95.

The GSM (Global System for Mobile Communication) is originated from Europe and it was based on TDMA ( time division multiple access). The IS-95 was the CDMA (code division multiple access) technology. The CDMA System has a very large capacity and is somehow better than GSM. As the security of data is more in CDMA as compared to GSM.  But as we know, every technology comes with flaws, it can be minor or even major. So even 2G mobile communication systems also had some shortcomings, which were that 2G supports only voice services and low speed data services.

So to overcome these flaws, finally 3G came into picture. The main target of third generation mobile communication is to implement broadband multimedia communication and high- speed data services to subscribers. The main technologies of 3G are UMTS WCDMA, CDMA 2000. 3G was developed to achieve high spectral efficiency and high quality of service with complete security and reliability. 3G is named as IMT 2000. This technology is providing  remarkable  services to subscribers. But to satisfy the growing demands of users, now 4G is developed.

4G is named as LTE. The fourth generation cellular systems need to meet the requirements set out by ITU as a part of IMT Advanced. It has worldwide roaming capability. It provides extremely high data rate services.

Now even 5G is being developed, which clearly shows that India, being a developing country is not that behind from other countries in terms of technology now. But the matter of fact is just that proper management and utilization of manpower and resources would definitely take India a long way in the race.

As there is such a drastic evolution in the field of telecom. So the need of manpower is increasing exponentially. There are many Multinational  Companies that are playing a vital role in the expansion of this field. They are contributing in different ways in telecom. Some companies are providing operator services. While some are manufacturers of telecom equipments.Therefore there is a lot of scope in telecom.

Therefore for all aspiring engineers who are passionate about telecom, that day is not far when they will be working for their interest in a telecom industry. But only the fact that should remain stable in their mind is just that to if a person who really want to work in this field, then success is at his doorstep.. and no one can become hurdle in his success. As there are a lot of job opportunities in telecom and engineers can definitely find their piece of cake in this area.
