Five technologies for building 5G | EDN

5G is widely considered a mobile technology that won’t be available until perhaps 2020 or 2021, and even then, not widely. 
Cisco predicts that by 2021, a 5G connection will generate 4.7 times more traffic than the average 4G connection.

5G will be a quantum leap from today’s LTE-Advanced networks.

    Quantenna’s 8×8 MIMO smarts leverage millimeter wave bands for 5G Fixed Wireless Access×8-mimo-smarts-leverage-millimeter-wave-bands-for-5g-fixed-wireless-access.html?cmpid=enl_cim_cim_data_center_newsletter_2018-11-19&pwhid=6b9badc08db25d04d04ee00b499089ffc280910702f8ef99951bdbdad3175f54dcae8b7ad9fa2c1f5697ffa19d05535df56b8dc1e6f75b7b6f6f8c7461ce0b24&eid=289644432&bid=2303764

    Quantenna Communications, Inc. (NASDAQ : QTNA) and Starry are reportedly joining forces to deliver pioneering gigabit Wi-Fi solutions in millimeter wave bands, leveraging Quantenna’s advanced 8×8 MIMO capabilities and Starry’s smart antenna RF technology.

    The integration of Quantenna 802.11ac and 802.11ax (Wi-Fi 6) chipsets in Starry’s base station technology, Starry Beam, provides end users with ultrafast speeds, increased bandwidth capacity, reliable connections and extended range. As noted at Light Reading, Starry first launched its pre-standard 5G, point-to-multipoint fixed wireless technology in 2016 in Boston; with Quantenna, Starry will continue to expand its network footprint to cities across the country, including Los Angeles, Washington, DC and New York City.

    The Quantenna QSR10GU and QSR10GU-AX solutions support up to 10Gbps speed, 8×8 MIMO and advanced multi-user MIMO, delivering the maximum capacity within the minimum utilized spectrum, resulting in superior performance in dense environments.

    Reinventing the electronic switch

    Menlo Micro was born in the research labs of General Electric, and is backed by GE Ventures, along with strategic investments from Corning, Microsemi and Paladin Capital Group.

    Menlo Micro is bringing this unique solution, a micro-mechanical relay that can handle thousands of volts and tens of amps of current, to emerging Power IoT applications and is also developing RF/microwave solutions to address the demands of next-generation 5G communications networks.

    Tiny waves, big challenges: Getting 5G mmWave mobility right–big-challenges–Getting-5G-mmWave-mobility-right?utm_source=Aspencore&utm_medium=EDN&utm_campaign=social

    5G promises 10× faster data rates and a 100× increase in network capacity, a feat only made possible by harnessing the wider bandwidths available above 20 GHz. Vast swaths of bandwidth from 24 GHz to 300 GHz, loosely referred to as millimeter-wave (mmWave), are the latest target for bandwidth-hungry applications. 5G NR Release-15 specifies frequency range 2 (FR2) for mmWave operations from 24.25 – 52.60 GHz, with three 3,000 MHz wide bands at 26.5 GHz, 24.25 GHz, and 37 GHz initially scoped for commercial usage, subject to local regulatory control.

    First movers have demonstrated commercially viable fixed 5G mmWave solutions, and 802.11ad (originally known as WiGig) served as a proving ground for light mobile communications between 57 and 66 GHz.

    And while innovation will push the limits of what is possible, mmWaves cannot defeat the laws of physics: smaller waves are more susceptible to atmospheric and environmental interference. That’s why really small waves present really big challenges.

    Reducing Costs and Commutes with a 5G-Based Software-Defined ITS

    Smoother traffic flows and safer roads could be around the corner with Intelligent Transportation Systems, or ITS, a technology that uses the Internet of Things (IoT) to gather and provide data on traffic speeds, car distances and potential hazards to drivers. While this technology has existed for some time, current deployments are costly and time consuming. To address these constraints, researchers have proposed a 5G-based software-defined network architecture that could reduce the expenses and time associated with ITS deployment.

    New Resonator Technology Targets Next-Generation Filters

    This company’s resonator technology could very well become a key factor in enabling filters for 5G applications.

    The smartphones that permeate today’s world wouldn’t be possible without the RF filters found inside of them. And with 5G rapidly approaching, the need for high-frequency filter solutions is only going to intensify. One company that’s making a significant impact within the mobile-communications filter space is Resonant. The firm recently unveiled its new technology, which it believes holds great promise for future RF filters for 5G mobile devices.

    “We’re a licensing company,” says Mike Eddy, vice president of marketing at Resonant. “We don’t make the filters, multiplexers, etc. We create the designs for our customers and then we license those designs on a per-unit royalty basis. Also, we announced the addition of filter IP library products to our offerings. Library products are designed and developed by Resonant against one of its foundry partner’s processes, tested against the latest industry and phone board requirements, and then made available to license.”

    Direct-RF DACs for high-speed communications

    Modern wireless radio transmitter designs encompass real IF (intermediate frequency) transmitters, complex IF transmitters, and zero-IF transmitters. At present, these transmitters continue to shuffle data through analog paths. There are limitations in the analog domain which impact the performance, capacity, and cost of the system, however.

    To meet the demands for higher bandwidth communications, IC manufacturers have developed direct-to-RF architectures that provide excellent spurious, low-noise performance with output update rates in the giga-samples-per-second (Gsps) range.

    Manhole Covers Serve as Antennas Expanding Wireless Network Coverage

    The inconvenient truth of future 5G networks is that their increased high-speed bandwidth, and the use of the millimeter wave spectrum (the radio spectrum above 30 gigahertz) to achieve it, comes at a price: Those radio signals barely propagate around the corners of buildings.

    To overcome this issue, the strategy has been a combination of small cells with massive multiple-input multiple-output (MIMO) antennas to increase coverage. Small cell deployment will be so extensive that the Small Cell Forum predicts 5G small cell will overtake 4G small cells by 2024. The total installed base of 5G or multimode small cells will reach 13.1 million by 2025, constituting more than one-third of the total small cells in use.

    Design and Optimization of FBAR Filters to Enable 5G

    While 4G LTE and LTE-Advanced technologies are still being deployed worldwide, the next generation in wireless communication promises a paradigm shift in throughput, latency, and scalability. By 2025, the emerging wireless 5G market is expected to reach a total value of $250B1. 5G is projected to be 100 times faster than 4G LTE and 10 times faster than Google Fiber (a physical connection). To put this into perspective, a high-definition movie will take less than a second to download on 5G, compared to 10 minutes on 4G LTE. Data rates will be further improved by using massive multiple-input multiple-output (MIMO) technology that originally were designed for use in IEEE 802.11n Wi-Fi networks.
