Issues In Designing 5G Beamforming Antennas


As 5G networking inches closer to reality, one of the more stubborn problems also will be one of the smallest. Several issues have yet to be cracked with beamforming and massive MIMO antennas, which will make millimeter wave (mmWave) spectrum—a key ingredient in 5G networks—work on multiple devices and base-station locations. Millimeter wave is problematic yet promising. Between bands 30... » read more

Kumu Networks: Full Duplex on One Channel


Kumu Networks is in an enviable position fitting today’s requirements for radio-frequency system designs. The Sunnyvale, Calif., startup, incorporated in 2011 and coming together the following year, has developed self-interference cancellation technology, enabling radios to send and receive signals at the same time on the same channel or on an adjacent channel. This full-duplex technology has... » read more

5G Test And Deployment


Advantest’s Adrian Kwan talks about 5G test, how it will change as the wireless technology evolves toward higher frequency signals, and what happens when many more users and backward compatibility are added to the network. https://youtu.be/x_-3yX7fWak » read more

Will 5G Deployment Lag in the U.S.?


China and other countries are creating “a 5G tsunami” that the U.S. will not be able to match unless it steps up its national investments in 5G cellular communications, Deloitte Consulting warns in a new report. The firm notes that China has outspent the U.S. on wireless communications infrastructure by $57 billion since 2015, constructing 350,000 new sites, compared with less than 2... » read more

Software-Defined Test And Measurement


Software-defined radios, instrumentation and test are ramping up alongside a flood of new technologies related to assisted and autonomous vehicles, 5G, and military/aerospace electronics, breathing new life and significant change into the test and measurement market. Software-defined test adds flexibility in markets where the products and protocols are evolving or still being defined, and wh... » read more

Wireless Test Faces New Challenges


Your mobile phone is far more complex than it was even five years ago, and it’s about to become even more complex with new wireless technologies. That has set off a scramble among test equipment vendors to come up with solutions, methodologies and equipment that is affordable, effective and reliable enough to make sure all of this technology works as planned—and that it continues to work th... » read more

Preparing For 5G


If you like 4G LTE, you’re going to love 5G. The next-generation wireless communications technology will offer faster data transmission speeds and lower latency, providing the processing power to drive augmented-reality and virtual-reality applications for mobile devices and dedicated headsets. There is a caveat, though. The world needs to develop a consensus on what the 5G spectrum wil... » read more
