Waiting For 5G Technology


For some time, carriers, equipment OEMs and chipmakers have been gearing up for the next-generation wireless standard called 5th generation mobile networks, or 5G. 5G is the follow-on to the current wireless standard known as 4G, or long-term evolution (LTE). It will enable data transmission rates of more than 10Gbps, or 100 times the throughput of LTE. But the big question is whether 5G wil... » read more

Interference In The Car


Once again, a paradigm shift is upon us. Mobile connectivity has radically changed the automobile’s place in the world of connected everything. And that paradigm will shift even further once the IoE is in full bloom. As all of this unfolds and technology marches on, some see the connectivity of the automobile as being a better and more powerful alternative to the smartphone. It is touted a... » read more

Inside The 5G Smartphone


Amid a slowdown in the cell phone business, the market is heating up for perhaps the next big thing in wireless—5th generation mobile networks or 5G. In fact, major carriers, chipmakers and telecom equipment vendors are all rushing to get a piece of the action in 5G, which is the follow-on to the current wireless standard known as 4G or long-term evolution (LTE). Intel, Samsung and Qualcom... » read more

Antennas Everywhere


A simple rule when it comes to electronics is that while digital circuits scale, antennas do not. That may not sound like a serious problem until you consider that as more devices get connected—cars, watches, industrial equipment—and they add more features that require interaction with the outside world, they need more antennas to make it all work. In the future, there literally will be... » read more

MIMO Maximum Likelihood Detector


MIMO (Multiple Input and Multiple Output) is one of the leading approaches for improving data rates and/or SNR (Signal to Noise Ratio). By using multiple receive and transmit antennas, MIMO can exploit the diversity of the wireless channel. This is then used to increase the spectral efficiency of the channel and improve the data rates for any given channel bandwidth. This white paper reviews... » read more

Talk, Talk And More Talk


By Ed Sperling To anyone who owns a cell phone—and there are at least several billion people who claim that distinction these days—it’s not surprising that bad reception lowers battery life. More bars, while not the most accurate gauge of a signal, are at least an indication that you can extend the time between charges even if you’re watching streaming video. But work is under way a... » read more
