Course details

Wireless communication has changed a lot in the last few years. Earlier, 2G systems like GSM could only send data at very slow speeds of about 10 Kbps. Today, modern wireless systems can deliver very high-speed internet, even more than 100 Mbps. This huge improvement led to advanced technologies like 3G and 4G, including HSDPA, LTE, and WiMAX. These high speeds are possible because of smart technologies such as CDMA, OFDM, and MIMO. These methods help many users communicate at the same time, improve data speed, and make better use of available bandwidth. This course explains these core technologies clearly and helps learners understand how modern 3G and 4G wireless systems actually work.
