Carrier aggregation enables service providers to join different spectrum bands to create the equivalent of a contiguous 20MHz channel capable of delivering peak LTE speeds of 150Mbit/s. In addition to the 4G LTE demos, Broadcom is announcing a range of new mobile technologies and momentum in driving the adoption of next generation wireless technologies into all product segments.
For its live 4G LTE demos, Broadcom is using its recently announced 4G LTE-Advanced modem, implemented in a 4G LTE smartphone reference platform built by Broadcom. In the carrier aggregation demo, two channels are aggregated, with one channel turned on and off during the demo to show the doubling of peak speed from 75Mbit/s to 150Mbit/s. In a separate setup, the same 150Mbit/s peak speed is achieved using 20MHz of contiguous spectrum. Additional demos will showcase the power savings of the BCM21892's envelope tracking technology and the high call quality of its Voice over LTE (VoLTE) services. In addition, Broadcom will be showing its BCM21892 smartphone platform in live, over-the-air demonstrations.
Broadcom's multi-mode, multi-band LTE solution is the industry's smallest 4G LTE-Advanced modem. It combines a full-featured cellular base band with a world-band radio in a footprint that is approximately 35 per cent smaller than current industry solutions.
An overview of the BCM21892 can be found on Broadcom's website. The BCM21892 is now sampling to early access customers with anticipated production in 2014.

Blue light emitting diode (LED): From light bulb to diabetes cure
Researchers have modified an anti-diabetic agent to make its action dependent on light, resulting in a compound that induces insulin release only when pancreas cells are exposed to blue LED light.
In this platform, TSMC offers multiple processes to provide significant power reduction benefits for IoT and wearable products and a comprehensive design ecosystem to accelerate time-to-market.
