NYU Wireless Leads the Drive Toward a New Kind of Network a whole new way of thinking of macronetwork design, you'll have to make more use of small cells and new technology like beamforming to focus RF to users. You can't expect ex- isting infrastructure to add millimeter wave 5G and cover the same area." Rappaport and NYU Wireless pushed the FCC in 2014 and 2015 to open up the new mmWave spectrums and in October 2015 the FCC announced the Spectrum Frontier Proceeding (SFP). They officially approved the SFP in July 2016, opening up nearly four times as much bandwidth for the mobile industry and making the US the first nation in the world to open the higher band spectrum. "More spectrum is great and we will figure out how to take advantage of it," Moten said, adding, "We can't forget the other parts of the ecosystem that will need to be updated to support the spectrum. There are three ways to address the high capacity needs for 2020. It's technology, spectrum, and densification. For technology we need to standardize 5G. For spectrum it's great to have mmWave but that won't be enough. Density is the key to reuse and make more efficient use of the spectrum. It's going to be a hetnet to really satisfy everything we're expecting the requirements to be in 2020. Cellular, 5G, Wi-Fi, 802.11 standards like Halo; all these new technologies are going to have to work together." With the SFP approved and new bandwidth ready for use, NYU Wireless has more than 100 researchers dedicated to developing the first round of 5G technology and the first steps toward the new kind of network Moten mentions are being made. NYU has made their channel model simulator software and measurement data open for anyone's use in an effort to drive the industry forward and they are hopeful 5G technology could potentially be ready for consumer use by 2018, ahead of the initial projections of 2020, though Moten says he is "very cautiously opti- mistic" about the 2020 dates feasibility, let alone an earlier roll out. "They're going to have to agree on a standard quickly to allow for development and testing, as well as handset devel- opment," Moten explained. "There is a lot of work to do and the outcomes of these trials will be critical, but agreeing to a standard is the first big hurdle."

Bill Moten, Vice President, TESSCO Technologies The Customer A Midwestern nuclear power facility that employs more than 1,000 workers and covers a campus of more than 5,000 acres. Among the world's top reactors, it provides enough electricity for 780,000 average homes per year. The System The facility was served by a TE Fusion DAS system that had been designed in conjunction with Cingular/AT&T and was locked at 850 MHz. Due to AT&T's phase out of their GSM 2G services the facility required an upgrade to their DAS system to accommodate multiple carriers and 4G. They also wanted to be able to operate their own system and be able to perform their own maintenance in case of emergency, while providing coverage to all on-site personnel regardless of provider. The Challenge Because of the security protocols in place for the power plant, this project presented additional unique challenges beyond the scope of the network. Security escorts were required for all non-employees and it was difficult for non-US citizens to gain access to be part of the project. When it came to the installation, the size of the campus and its remote location presented challenges. Because of nuclear requirements, the structure itself was extremely dense, with deep concrete and metal that had to be accommodated. There were also specific cabling requirements for the facility that had to be met. The Solution TESSCO replaced the existing TE Fusion System with a TE/ CommScope Spectrum system. The Spectrum System is well- received by carriers and is approved by all four national service providers. The DAS remotes used on the project did not have AC or DC power available so a Line Powered solution was needed. They were able to utilize existing cable, saving money, and additional cable was pulled using existing pathways to help speed up installation. Finally, the fiber plant used consisted of Multimode and Single mode fiber, which provides the industry's best support. Why TESSCO Was Chosen Having an existing relationship with the team managing the plant helped TESSCO understand the scope and needs of the project from the start. TESSCO Solution Architect Tom Ulrich collaborated with the customer and determined that TE's DAS solution would be the best fit because of the existing TE installation and because of single mode/multimode limitations. As part of TESSCO's single source, end-to-end solution, Ulrich then helped the customer scope the project and worked to meet their budget, then he coordinated a series of calls with TE, the customer, TESSCO, and AT&T to align on a system that all parties could agree on. Once the system was agreed on, Ulrich traveled to the cus- tomer location for an on-site survey and walkthrough with the manufacturer to develop a final system design and a compre- hensive Bill of Materials which met the customer's sole source guidelines to issue a no-bid P.O. to TESSCO. Once the P.O. was received, materials were delivered within the customer's tight timeline. In addition to fulfilling the network installation needs, as a total source supplier, the company was also able to supply addi- tional equipment and services to the customers following the in- stallation. TESSCO provided spare equipment, antennas, cables, and connectors and, because the customer was installing and maintaining the system on their own, also provided on-site DAS training for their employees. During the course of the training the customer was introduced to the Keysight FieldFox tester and subsequently purchased one for their use as well. TESSCO was also able to use their extensive network of VARs to introduce the customer to a provider for commissioning and maintenance services. The installation was successfully completed ahead of schedule in February 2016 and TESSCO helped the customer facilitate adoption among the carriers including overcoming some initial resistance, thanks to TESSCO's relationships with key individuals there. The Results By working with TESSCO the customer gained experience installing a DAS system that they can utilize in other areas. They've also realized the benefits of faster and better com- munications by extending their 4G coverage throughout their facility and implementing LTE, and they can project future returns thanks to the scalable DAS system that will grow with their communications needs. A Nuclear Power Plant's Winning Strategy For Updating Their DAS Submitted by Mary Beth Smith, Vice President, Sales, TESSCO Technologies This opportunity was the epitome of TESSCO as the customer's Total Source -engineering services, training services, and multiple product business units contributing to an end-to-end solution that ultimately streamlined the customer's procurement and helped them reduce costs. TESSCO was also able to bring together key manufacturers, carriers, and a VAR to go above and beyond to solve our customer's key challenges. " Tom Ulrich, TESSCO Solution Architect TESSCO's TAKE "
