Verizon to bring 5G fixed wireless access to Houston

In a challenge to Comcast's Xfinity and AT&T's U-verse broadband and video residential services, Verizon will launch a 5G fixed wireless access service in Houston before the end of the year.

Verizon has previously announced Sacramento and Los Angeles as launch cities for its residential 5G broadband service.

Verizon CEO Lowell McAdam, CTO and incoming CEO Hans Vestberg are hosting a news conference with Houston mayor Sylvester Turner.

“We expect 5G will be a game changer helping us usher in a new wave of progress and innovation,” said Mayor Turner. “We’re delighted to be one of the first cities to bring 5G to our local communities and look forward to continuing our long-standing relationship with Verizon.”

“We will be the first to offer commercial 5G service and our work with Houston put us one step closer to delivering that promise,” said Verizon’s Vestberg. “With 5G we are ushering in a fourth industrial revolution that will help reshape cities and lead to unprecedented innovation, and Houston will be at the forefront of that innovation.”

Verizon readies 5G fixed residential service launch in 2018

Verizon's first 5G application will be a fixed residential broadband service.

The first commercial launch will occur in Sacramento, California during the second half of 2018. Additional markets are also expected to launch in 2018.

Verizon did not disclose the performance characteristics of its 5G residential service but said it will provide unprecedented wireless speeds for Internet access.

Verizon estimates the market opportunity for initial 5G residential broadband services to be approximately 30 million households nationwide. The company also noted that the 5G residential rollout will not have a material impact on Verizon’s consolidated capital expenditures in 2018. CAPEX is expected to be consistent with the past several years.

“This is a landmark announcement for customers and investors who have been waiting for the 5G future to become a reality,” said Hans Vestberg, Verizon president of Global Networks and Chief Technology Officer. “We appreciate our strong ecosystem partners for their passion and technological support in helping us drive forward with 5G industry standards, for both fixed and mobile applications. The targeted initial launches we are announcing today will provide a strong framework for accelerating 5G’s future deployment on the global standards.”

Verizon picks Samsung as a supplier for Fixed 5G

Verizon has selected Samsung Electronics America as a supplier of commercial 5G Fixed Wireless Access (FWA) network solutions. Verizon will begin by launching commercial 5G services in Sacramento, California in the second half of 2018. Financial terms were not disclosed.

Specifically, Samsung will provide Verizon with commercial 5G home routers (CPEs), 5G Radio Access Units (RAN) comprised of a compact radio base station and virtualized RAN elements, as well as 5G radio frequency planning services. Samsung said it has leveraged in-house technology and assets to develop the first commercial ASIC-based 5G modems and mmWave RFICs.

Samsung and Verizon began 5G customer trials across seven U.S. cities in early 2017, and have successfully tested and verified 5G performance using millimeter-wave (mmWave) frequency to provide FWA pre-commercial service. These trials were conducted in California, Georgia, New Jersey, Massachusetts, Michigan, Texas, and Washington D.C.

The companies cited the following findings from their 5G testing:

  • A single 5G radio has been able to reach the 19th floor of a multi-dwelling unit (MDU).
  • Broadband service has been achieved in line of sight (LOS), partial LOS and Non-LOS connections.
  • Environmental factors, including rain and snow, have not interrupted services.

“The industry has been discussing 5G connectivity for years, and through our joint collaboration with partners like Samsung, we are beginning to make it a reality for our customers," said Ed Chan, Chief Technology Architect and Network Planning, Verizon.

U.S. Cellular Tests 5G for Fixed Wireless with Nokia

U.S. Cellular is working with Nokia to test 5G fixed wireless in both indoor and outdoor environments.

Nokia said the 5G testing used 28GHz spectrum through an experimental license from the FCC and Nokia's commercially-available, 5G-ready AirScale radio platform to stream six simultaneous 4K ultra high-definition videos.

For the outdoor testing, which was conducted at U.S. Cellular's technology center in Schaumburg, Ill., the team set up a point-to-point, clear line of sight scenario between a base station and user equipment. To test the impact of a real world environment, impairments such as dry wall, windows and metal panels were introduced, and testing was repeated by moving the base station and user equipment behind trees and foliage. The indoor testing was done in U.S. Cellular's lab. In both environments, the tests delivered speeds of 5Gbps and ultra-low latency under 2 milliseconds (ms) over the 5G wireless link.

Ricky Corker, executive vice president and head of North America for Nokia, said: "Nokia continues to accelerate its efforts to develop and test 5G in North America, and we're pleased to expand our relationship with U.S. Cellular with this newest 5G collaboration. Our tests show how 5G technology not only will enhance U.S. Cellular's ongoing efforts to stay ahead of the needs of their data-hungry customers and businesses, but also create opportunities for new services requiring high bandwidth and low latency."

DragonWave Whitepaper: Unlocking the Value of E-Band with Extended Reach

by Greg Friesen,
Vice President of Product Management at DragonWave

When first- and second-generation E-Band systems introduced Gigabit wireless systems to the market, they took advantage of the wide amount of spectrum available which is very low-cost, to be able to offer high capacity wireless links.  However, these systems did not focus on reach and were inhibited by the high amount of rain fade present in the 70/80 GHz frequency bands. As a result, current E-Band systems have been limited to about 1-3 Km reach, resulting in a limited application space that has been primarily last mile fiber extension in enterprise and campus environments.

With the next generation of E-Band systems, and a number of features targeted at extending reach, manufacturers are now effectively doubling previous link lengths and achieving up to 7 Km of reach. This increased reach is critical to expanding the application space of E-Band products. Now, with extended reach capabilities, 70/80 GHz can be used for the traditional cellular backhaul market. These E-band ranges are comparable to 38 GHz links ranges and can be used for many 23/26/28 GHz links as well.

Using the 70/80 GHz band as a spectrum alternative to traditional 23-42 GHz links has tremendous advantages. In the 23-42 GHz band, many countries issue a maximum channel size of 28 MHz channels, limiting link capacities to 200-250 Mbps. A few countries will issue channel sizes up to 56 MHz, still limiting capacities to about 500 Mbps.  However, 250 and 500 MHz channels are generally available in the 70/80 GHz band. Using these channels, today’s products can deliver 1-3 Gbps of capacity and provide operators with tremendous scalability to meet growing LTE requirements. In addition, E-Band systems offer significant total cost of ownership benefits by leveraging spectrum that costs about 1/10th as much as 23-42 GHz spectrum, as shown in Figure 1 below.



The benefits of E-Band versus 23-42 GHz are significant and offer 10 times the capacity with 1/10th of the recurring spectrum costs.  Nevertheless, in order to take advantage of these benefits, reach needs to be >4 Km, which is comparable to the 23-42 GHz bands.  First- and second-generation E-Band systems could not transmit this far and were typically limited to about 2-3 Km. of reach. Today, a number of new technologies are emerging to increase that reach twofold.
The first of these technologies is adaptive modulation, which monitors signal strength and shifts from the current modulation to a lower modulation during a fade event. Utilizing this technique, the system will shift from 64QAM all the way down to BPSK, resulting in a 15-20 dB link gain improvement.

The next area of reach improvement is adaptive waveform. Once the system has tried to compensate for path fade using adaptive modulation, it can then shift to smaller channel sizes, from a typical 250 or 500 MHz channel down to a 25 or 50 MHz channel. This adaptive waveform switching improves the receiver sensitivity, further increasing link budget by about 10 dB.
The last technique that can be used to extend the reach of an E-Band system is MIMO (multiple input, multiple output). In E-Band, MIMO can be used to transmit the same signal over two spatially separated antennas. This is different than traditional forms of MIMO which use spatial separation to achieve a doubling of capacity. In this case, spatial separation is used to get improved link budget by having 2X antenna and Receive side gain, thereby improving the total system gain by up to 9 dB. Due to the high frequency range of E-Band, the separation of the antennas required for MIMO can be very narrow, allowing them to be packaged into a single unit.

The combination of these three features can extend E-Band range to >6 Km. The graph below shows the impact of these features for a link designed at 99.99% availability in Europe.  Even at this high availability, link lengths close to 6Km are achievable.

Extending the range of E-Band is a very important step in extending the applicability of E-Band. Taking this extended range and mapping it across an existing mobile network in Europe allows one to determine how applicable E-Band could be as an alternative to 23-42 GHz microwave systems. In this case, the existing links were consuming 28 MHz channels and delivering 20 Mbps of capacity. It was found that 99% of the 38-42 GHz links could be replaced with E-Band, a further 70% of the 26-32 GHz links could be replaced, and 55% of the 23 GHz links could be replaced, which amounts to 75% of the full field population of 23-42 GHz links being viable for E-band deployment.

Further analysis compares three deployment scenarios from a cost perspective. The first scenario replaces the link with an E-Band link, increasing the capacity to 2.5 Gbps, but incurring CAPEX and install cost. The second scenario leaves the current 23-42 GHz links in the field, but not being able to scale beyond 200 Mbps and continuing to incur the high spectrum lease costs. The third scenario expands the existing microwave system to 56 MHz and adds a second XPIC channel in the 23-42 GHz range. This scenario incurs CAPEX and install costs, but scales to 1 Gbps, although it will result in costly recurring spectrum charges. In addition, the third scenario may not always be deployable, as it is often not possible to acquire 2X 56 MHz channels. All three scenarios are compared for 7 years, and shown in the graph below.



As shown in the graph above, the E-Band scenario offers slight cost savings over leaving the existing system in the field and provides greater than 10X scale. It also is by far the lowest cost option for providing any scalability beyond 200 Mbps.

It’s clear that E-Band systems have evolved tremendously over the past five years. In doing so, the reach and corresponding addressable market has expanded significantly.  With new reach capabilities of >5 Km, E-Band systems are now a viable alternative for enhancing mobile backhaul networks. For operators, the new E-band solution is something that should be highly considered, as it provides a viable means to deliver >1 Gbps, while also achieving major spectrum cost savings.
