Much like the 2017 event, this month’s IEEE International Microwave Symposium 2018 (IMS) was abuzz with talk of 5G applications, rollouts, and developments. But nowhere was that focus more singular than Monday’s (June 12) 5G summit, whose speaker lineup looked like a connectivity all-star roster.
The transition from previous 802.11 standards, such as 802.11n and 802.11ac, to 802.11ax adds several new technologies and performance requirements that need to be fully tested. However, there are a number of challenges in designing these test scenarios.
Whether it’s a matter of national security or commercial success, a space plane or a sensor, brilliant people regularly refrain from trumpeting their astounding scientific achievements. It's not always easy or popular, but it's necessary, and I tip my hat top you, secret-keepers.
NR is billed as a more capable air interface, and will need to operate in both the frequencies below 6 GHz and above 24 GHz (mmWave) with a frame structure supporting both TDD and FDD, as well as operate in both licensed and unlicensed spectrum.

A phased-array antenna is made up of multiple individual radiating elements and each is fed with an RF signal controlled through phase shifters in such a way that the radio waves from the separate antennas are added together to increase the radiation. The advantages inherent in phased-array systems will enable major new commercial applications, including 5G communications and automotive radar, to exploit the millimeter-wave (mmWave) spectrum. This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems, and examines the new capabilities recently added to electronic design automation (EDA) software such as the NI AWR Design Environment platform.
Antenna aperture tuning is essential to enable smartphones to operate efficiently over the ever-increasing range of RF frequency bands and support the transition to 5G. Smartphones need more antennas to support growing RF requirements such as new 5G bands, MIMO, and carrier aggregation (CA), but there is less space for these antennas due to changes in smartphone industrial design. As a result, antennas are becoming smaller, potentially reducing antenna efficiency and bandwidth. Aperture tuning compensates for this problem by allowing antennas to be tuned to operate efficiently on multiple bands and increasing Tx and Rx performance by 3 dB or more.
Wireless InSite’s Communication Systems Analysis module is a set of post-processing routines that builds on the X3D model’s high-fidelity MIMO calculations to predict system throughput and bit error rate. This example utilizes these routines to analyze throughput between three small-cell base stations employing Full Dimension (FD) MIMO beamforming to User Equipment (UE) moving along a route, using 5G New Radio (NR) in a dense urban environment.
Next-generation 4G/5G telecommunication systems require power amplifiers (PAs) to operate with high efficiency over a wide frequency range to provide multiband and multi-standard concurrent operation. This application note describes the design of an innovative Doherty amplifier architecture using 200-W high-efficiency broadband 1.8-2.7 GHz GaN high-electron mobility transistor (HEMT) technology, which achieved average efficiencies of 50-60 percent for output powers up to 100 W and significantly reduced the cost, size, and power consumption of the transmitters. The designers used the NI AWR Design Environment platform, specifically Microwave Office circuit design software.
Every time a new cellular phone standard comes out, we see new claims about the “end of Wi-Fi.” When 3G was announced, the promise was that it would make Wi‑Fi (802.11b) redundant, which clearly turned out to be incorrect. With 4G (LTE), this story repeated itself and claimed it would put Wi‑Fi (802.11ac) in the shredder. And now the 5G message is that it will cover both the inside and outside of homes and buildings. It’s almost as though Wi‑Fi will soon no longer be needed. This begs the question: What will be the impact of the next generation of Wi‑Fi, Wi-Fi 6 (802.11ax)? Do we even need it in the 5G/wireless landscape? This article discusses the answers.
