TD-LTE (Time Division Duplex LTE) is one of the two operation modes of LTE. Contrary to FDD-LTE (Frequency Division Duplex LTE), LTE’s other mode of operation, TD-LTE uses unpaired spectrum. With a great number of unpaired frequency bands including 2.3 GHz, 2.6 GHz and 3.5 GHz now available for TD-LTE deployment, the unpaired mode is attractive to both greenfield and traditional operators. TD-LTE has gained significant traction in many big markets such as China, Saudi Arabia, India, Russia, Australia, Latin America and North America.
India is taking a leading position in deploying TD-LTE as a 4G technology to meet the pent-up demand of its population. Currently less than 1% of India’s 1.2 billion population has access to broadband. Unpaired frequency bands, unused up to now, are therefore a great option for operators for offering broadband access to an ever increasing subscriber base.
At Nokia Siemens Networks we are engaged in TD-LTE field trials with three major Indian operators including Aircel, a joint venture between Maxis Communications Berhad of Malaysia and Sindya Securities & Investments Private Limited. Aircel, one of the fastest growing operators in India with a 50 million subscriber base, owns the largest chunk of next-generation spectrum in the country including eight circles* of broadband wireless access (BWA) spectrum. The operator has chosen 3GPP-standardized TD-LTE to provide access to the urban as well as the rural masses. Aircel selected us for its trial network in Hyderabad, India, because of the unprecedented Radio Access Network (RAN) capacity and proven quality of our TD-LTE equipment including the award-winning Flexi Multiradio Base Station. So we are working closely with Aircel to drive TD-LTE commercialization in India.
With its high throughput and low latency rates, TD-LTE “is going to bring a revolution in the commercial market and for the end user,” said Pankaj Raja, national core project manager at Nokia Siemens Networks, in our recent video about the field trial with Aircel.
Check out the video for more insights on the trial set-up. It shows
– How the TD-LTE field tests are running
– How TD-LTE can be easily migrated to LTE-Advanced with a software upgrade only
– How our experts on the ground are closely co-operating with the Aircel team to leverage the capacities of TD-LTE for delivering mobile broadband to masses.
As Mallikarjuna Rao, CTO, Aircel, suggested, TD-LTE is now for real: “It is available for us to go and deploy commercial services.”
