SOLiD Launches RocketWAVE Technology mmWave 5G Platform

SOLiD  launched the SOLiD RocketWAVE 5G off-air repeater platform at the Mobile World Congress this week in Los Angeles.

The RocketWAVE solution will provide millimeter wave (mmWave) signal distribution, 5G performance, speed and capacity indoors. New RocketWAVE mmWAVE products offer a simple, economical solution to assure seamless in-building service for mobile operators wishing to extend their mmWave networks indoors in the United States. RocketWAVE mmWave products will support 24GHz, 28Ghz, and 39GHz individually.

Without reliable in-building solutions, 5G subscribers will experience a drastic drop in performance every time they walk indoors, resulting in poor customer experience often leading to high churn rates. This issue is particularly problematic with new mmWave frequencies, given their higher attenuation and short propagation nature. Moreover, the challenge of extending 5G coverage indoors is further complicated by the increasing use of energy-efficient building materials, which can block or weaken many RF signals.

“The reliance on an outdoor-to-indoor strategy for 5G mmWave coverage depends on the assumption that small cell sites on lower height poles and structures are readily available. EJL Wireless Research has proven this strategy to be flawed, given the state of 5G mmWave networks across the U.S. currently,” said Earl J. Lum, Founder and President, EJL Wireless Research. “The RocketWAVE solution bypasses the requirement for small cell sites to deploy 5G mmWave radios, and allows for the mobile operator to directly feed 5G mmWave signals indoors from off-air repeaters deployed on rooftops. This enables support for enterprise users without the need to try to beam the signals through Low-E Glass windows or require outdoor CPEs to be mounted below the tree line.”

“While everyone is focused on how to plan their networks to build out sufficient 5G outdoor coverage, the fact remains that up to 80 percent of mobile traffic occurs indoors,” said Ken Sandfeld, President of SOLiD Americas. “Our new RocketWAVE 5G technology platform unleashes the full potential of mmWave 5G performance where 5G subscribers want service, indoors. RocketWAVE will provide ‘hotspot’ 5G service exactly where the mobile operator wants it, allowing carriers to deliver an outstanding, seamless 5G experience that lives up to the hype.”

SOLiD has not yet announced a shipment date for this new product, but deliveries are expected to begin in 2020.

mmWave Technology Has Proven its Viability for Use in 5G: Qualcomm

By J. Sharpe Smith, Senior Editor

LOS ANGELES– Last year Alejandro Holcman, SVP, corporate engineering at Qualcomm, was peppered with questions surrounding the viability of millimeter wave (mmWave) spectrum as he spoke at the Mobile World Congress Los Angeles. This week, he proudly announced that many, if not most of those questions have been answered, during this year’s Light Reading breakfast event at the Mobile World Congress Los Angeles, being held this week.

“People wanted to know whether the mmWave band works for wireless technology. Is it only line of sight? What happens when you go indoors?” Holcman said. “I am really excited that we have infrastructure and real phones that use mmWaves. They are the same form factor as other mobile phones. You can do a lot with mmWave spectrum. In some cases, indoors, it is really incredible the things you can do.”

Holcman described a coverage test at Qualcomm’s headquarters in San Diego, and an mmWave site was placed pointing out toward the front door of the lobby, away from the offices, using the 28 GHz band.

“We expected significant coverage in front of the antenna,” Holcman said. “But technicians got better coverage than they expected.”

Significant coverage was experienced behind the gNodeB, including the second and third floor. The downlink median burst rate was 3.1 Gbps.

“We were very excited about how mmWave was working. We got gigabit speeds even behind the antenna because of the amount of reflections in the lobby,” Holcman said. “There are articles that say mmWave is only for line-of-sight coverage and doesn’t go around corners. But there were a lot of reflections and we got healthy coverage elsewhere in the building.”

Next, Holcman describe a coverage test in the South Hall of the Los Angeles Convention Center, where four mmWave antennas were installed to cover 350,000 square feet. Full downlink coverage was achieved with 115 dB maximum allowable path loss (MAPL). The downlink medium burst rate was 1.6 Gbps using a 400-megahertz-wide channel.

“We pretty much had full coverage, something that would be very expensive to do if you needed to isolate individual sectors in lower bands,” Holcman said. “This is the kind of capacity that mmWave is capable of providing.”

Additionally, Qualcomm has analyzed how using mmWave spectrum can provide coverage in afootball stadium with 100,000 fans uploading selfies and video and tweeting their friends. A typical stadium of that size, according to Holcman, might have a DAS with as many as 100 sectors.

“Stadiums are very expensive place to provide wireless coverage. With just 15 mmWave sites, the whole stadium was covered. The mmWave cells provide a more uniform user experience. Medium downlink throughput at all levels was more than 700 Mbps. Cell edge throughput was greater than 100 Mbps.

Another study was done in a Latin American city, where Qualcomm looked at 5G NR mmWave fixed wireless access to a 4.34 square mile dense urban area. The average building height was 39 feet and 90 percent of the buildings were less than 98 feet. Close to 90 percent coverage of the buildings was achieved with 149 LTE/5G NR mmWave small cells. The small cells used 28 GHz, 800 MHz and 100 MHz, 256X2 element antenna with beamforming, 64 QAM and 2X2 MIMO.

“We are also excited about using mmWave for fixed wireless access. It is like a replacement for fiber with a mmWave CPE on every rooftop,” Holcman said.

The progress in mmWave technology did not occur overnight. It has been a busy 12 months for Qualcomm working on mmWave technology since the last Mobile World Congress Los Angeles.

Most recently, in September, Qualcomm Technologies, introduced the Qualcomm QTM527 mmWave antenna module for the Snapdragon X55 5G Modem-RF System, delivering the a fully integrated extended-range mmWave solution for 5G fixed wireless access. This allows mobile operators to offer fixed internet broadband services to homes and businesses using their 5G network infrastructure. Before that, in August, Fujitsu Limited and Qualcomm Technologies completed non-standalone (NSA) 5G New Radio (NR) data calls on 3.7 GHz and 4.5 GHz bands and the 28 GHz band. In July, Qualcomm’s 5G NR testing facilities in Europe were expanded to include a new lab dedicated to end-to-end over-the-air (OTA) configurations for 5G NR mmWave.

Almost a year ago, Qualcomm and Nokia achieved OTA 5G NR data calls in both the mmWave and sub-6 GHz spectrum bands, which were compliant with the global 3GPP 5G NR Release 15 specification in NSA mode, using commercially available Nokia AirScale base stations, a mobile smartphone and antenna modules with integrated RF transceiver, RF front-end and antenna elements.

It has been five years since NYU WIRELESS, a multidisciplinary research center with more than 100 researchers, was founded to develop the fundamental theories and techniques for next generation mass deployable wireless devices.

A key focus of the center, based at the NYU Tandon School of Engineering, relates to millimeter wave (mmWave) systems operating in the high frequency bands above 10 GHz.

In 2013, NYU WIRELESS Founding Director Theodore (Ted) S. Rappaport published “Millimeter Wave Mobile Communications for 5G Cellular: It Will Work!” which defied common wisdom that that lower frequencies represented the limits of possibility for most wireless communications.

“NYU WIRELESS is playing a vital role in this transformation and in providing its students the technical skills they’ll need to take advantage of the new career opportunities in this field,” said Melissa Arnoldi, senior executive vice president, Technology & Operations, AT&T Communications, which is one of the center’s industrial affiliates.

Research conducted at NYU WIRELESS was a key element in the FCC’s adoption of the Spectrum Frontiers Report and Order in 2016. Additionally, NYU WIRELESS was one of only two academic institutions chosen by the FCC to help test, debug, and provide feedback on a new web-based portal that lets researchers apply for a program experimental license, a development that will reduce barriers to experimentation for universities, research laboratories, health care institutions, and manufacturers.

The research also holds the promise of dramatically improving urban reception and reducing the cost of bringing fiber optic-speed Wi-Fi and wireless service to underserved rural areas, thus democratizing access and helping bridge the digital divide.

Among the research accomplishments of the center, now under the direction of NYU Tandon Associate Professor of Computer and Electrical Engineering Sundeep Rangan, are:

  • Making the world’s first radio channel measurements proving that the mmWave spectrum holds vast potential to improve wireless communications in urban centers
  • Launching the first open-access mmWave channel simulator software (NYUSIM) with a complete statistical spatial channel model, projected to cut years off the development time for next-generation mobile
  • Building one of the first advanced testbeds for antennae available to academic and public-sector researchers studying the mmWave spectrum
  • Creating the world’s first channel and beam-forming emulator for  5G mmWave channel emulator that will help to realistically evaluate virtual reality and other applications
  • Jump-starting technology that could enable first responders to relay video in moving ambulances, employ virtual reality in emergencies, receive high-definition images from drones in real time, or control robots in restricted indoor environments too dangerous for humans
  • Conducting the first study for rural mmWave coverage at 73 GHz, thus demonstrating  the viability of providing fiber-like wireless bandwidth to rural homes
  • Deploying a phased-array antenna system for measuring mmWave directional channel dynamics
  • Demonstrating the safety of mmWave radiation for the human body and creating mathematical models for the interface of mmWave cellphone signals and human tissue

NYU WIRELESS has nearly 20 industrial affiliates including AT&T, CableLabs, Crown Castle, Ericsson, Huawei, Intel, Interdigital, Keysight Technologies, L3 Communications, National Instruments, NextLink, Nokia, OPPO, Qualcomm, SiBeam, Sprint, UMC, and Verizon.
