Industrial Visit to Huawei Telecommunication
2nd March, 2017
IEEE Student Chapter, Dronacharya College of Engineering, Gurgaon organized an industrial visit to "Huawei Telecommunication India Pvt. Ltd" on 2nd March 2017, 48 students from IT, CSIT, CSE and ECE Department visited the company.
The objective of the industrial visit was to introduce students with various networking concepts like Wireless Telecom (2G/3G/4G), IP- Datacom (Routers, switches, Security & Firewall), Networks (Access, Optix, & Microwave) & Cloud Computing.
The Dronacharyans were welcomed by Mr. Atul Rajput, General Manager. He explained ICT and Telecom Industry is on a cross road facing different set of challenges that stem from ever challenging technology trends and customer expectations. The convergence of applications, devices, networks and content in this new-age information super highway has become the next path-breaking move in core mass-market technology providing single connectivity and integrated user experience.
Mr. Atul discussed 4G Technology. 4G refers to the Fourth Generation of cellular wireless standards in telecommunications that will succeed it predecessors 3G 2G. It is a high-speed broadband wireless network that offered comprehensive & secure all IP based services. It focuses on cellular system with extremely high data rates & the concept of seamless technology in all wireless systems. Carriers that are using OFDM (Orthogonal Frequency-Division Multiplexing) as an alternative to TDMA and CDMA are promoting their services as 4G even though their data rates are not high according to the ITU.
He also explained the following terms:
3GPP LTE: LTE (Long Term Evolution) has experienced peak download rates of 326.4 Mbps and 172.8 Mbps for 4x4 and 2x2 MIMO antennas respectively when using 20 MHz of spectrum and peak upload rates of 86.4 Mbps for every 20 MHz of spectrum using a single antenna. This means that it does not quite meet the 4G requirements but it is still often branded as 4G by telecommunications providers as it offers a considerable increase in performance over 3G. Its radio interface is often referred to as E-UTRA (Evolved UMTS Terrestrial Radio Access).
3GPP LTE Advanced: 4G LTE Advanced is not a new technology but rather an enhancement to the existing LTE standard by using multiplexing and additional spectrum range to achieve the speeds required for 4G; whilst help for system capacity usage is dealt with by co-ordinated multi point transmissions.
He discussed HCIG and HIT certification for ICT. It includes Core Network ( CS, PS, IMS) Transmission Network, IP- Data Communication Network, Cloud Computing Fundamentals, Wireless Broadband Access (MBB/ LTE/ WIFI) With engineers who are complete HCIG certified, companies are able to construct simple networks and integrate voice, wireless, cloud, security, and storage technologies into their networks in order to support a variety of applications.
After the theoretical aspects of networking, students visited the Huawei Lab.
The visit was informative and useful to the students as they learnt about various advance networking concepts.
