China is an increasingly important market for the growth of ET, as TD-LTE handsets stand to benefit from ET even more than with FD-LTE. TD-LTE handsets can only transmit for 20% of the available time, so when they are transmitting they need to use the maximum bandwidth and output power. Tests by Nujira have shown that you can achieve a 40% saving in energy-per-bit with ET when transmitting on full speed TD-LTE, even though the instantaneous power consumption during a TD-LTE burst can be double that of FD-LTE transmitting at lower speed. Earlier this year Nujira also demonstrated how its high bandwidth 20MHz NCT-L1300 ET modulator chip delivered twice the energy savings compared lower bandwidth ET systems.
Highlighting how ET technology is improving the battery life in LTE devices, Julian Hildersley, VP Partner Development, Graham Teague, Sales Director, and William Tse, Field Applications Engineer for China from Nujira will be speaking about optimizing ET systems and product calibration. Local AE Experts from Rohde & Schwarz China, will also be demonstrating a test solution to evaluate PA performance with ET technology including test setup, calibration data input, FDD test, TDD test, PAE test and ACLR Performance with ET implementation.
Julian Hildersley, VP Partner Development, Nujira commented: “Nujira and Rohde & Schwarz have been collaborating for many years on advancing ET technology. As TD-LTE networks roll out across China it is the perfect time to host this series of joint seminars, allowing us to come together and demonstrate the full benefits of ET to our Chinese partners and customers.”
The first seminar will take place on 19th September 2014 in Shanghai, with two further sessions scheduled for Beijing and Shenzhen.
About Nujira
A global wireless chip company headquartered in Cambridge, UK, Nujira is enabling the design of cost-effective multi-mode, multi-band mobile handsets that deliver faster data rates, longer battery life, and better coverage through the implementation of easy-to-use ET systems.
Nujira’s mission is to dramatically reduce the energy consumption of mobile devices, ultimately helping to increase battery life and reduce heat dissipation. The company’s patented Coolteq® Envelope Tracking chips dynamically modulate the power supply to the RF PA in line with the amplitude of the transmitted signal, enabling the creation of highly efficient RF Power Amplifiers for smartphones and other portable wireless devices.
Founded in 2002, Nujira’s tried and tested ET products have been leading the industry for the last 12 years. Employing over 60 people, Nujira is funded by leading European venture capital institutions and has gained significant ongoing commercial engagements with a number of leading smartphone manufacturers.
