FiberTower Releases "Wireless Fiber" Fact Sheet for Montgomery County ultraGig Partnership

Wireless Fiber Fact Sheet for ultraGig Partnership with Atlantech Online and Montgomery County, Maryland.


UltraGig: Gigabit ‘Wireless Fiber’

FiberTower Corporation and Atlantech Online have partnered to deliver the first exclusively licensed 24GHz full duplex 1 Gbps ‘wireless fiber’ link deployed in the Washington region, directly to the Silver Spring Innovation Center (SSIC).  This highly secure, exclusively licensed system is designed to federal physical-diversity standards.  It delivers a super-fast Gigabit connection to the SSIC conference rooms and tenants back to the Atlantech fiber network hub in downtown Silver Spring.

Broadband Video, Voice & Data: Boosting Local Business Development and Growth

  • Business growth depends upon the availability and convergence of high quality broadband for video, voice and data use.  
  • These connections offer high definition and high capacity interactive video and voice conferencing, as well as data intensive uploading and downloading.

Last Mile Connections to Underserved Buildings, Towers and Poles 

  •  By deploying “wireless fiber” high capacity links the county can enjoy last mile connections where such capacity is currently unavailable due to technical or economic challenges.  High-definition video editing and transfer, data-base connectivity and downloads and uploads, high-quality voice services and more are all possible over this technology.
  • 24GHz fully licensed fixed wireless connections can function as ‘wireless fiber extension cords’, extending the reach of existing fiber optic infrastructure and connecting additional customers, under-served office buildings and community anchor institutions.  This broadband extension cord service can be delivered through partnerships with local fiber companies and the county’s FiberNet fiber-optic network,
  • Small cell service can be delivered to buildings, light poles and other structures to provide the backhaul infrastructure for mobile networks, public safety networks and WiFi networks.  This means that broadband internet services can be supplied indoors or outdoors at under-served locations.

Physically Diverse Network (PDN) Connections – Avoid Outages

  •  A key way to avoid broadband outages is to bring Physically Diverse Networks (PDN) connections to a building or structure.  
  • PDN architectures require physical separation from the incumbent network at every point, including diverse ingress to and egress from the service premises, use of separate rights-of-way throughout the service area, and utilization of separate switching centers where the broadband connections terminate. [Sources: Bechtel Telecommunications Journal: Physically Diverse Networks Using Microwave; Pub. Law 108-447, Section 414]. 
  • Deployment example: The current Gigabit link installed between SSIC at 8070 Georgia Ave and Atlantech Online’s fiber hub at 1010 Wayne Avenue contains battery-based uninterruptable power systems in the event of a power outage and also can be individually powered through a generator system.  A secondary Verizon fiber connection to SSIC completes the physical diversity architecture. 

Fully Licensed 24GHz Spectrum Band

FiberTower is the sole holder of exclusively-licensed, wide-area 24GHz spectrum authorizations in the National Capital Region.   The choice of fixed wireless 24GHz spectrum for use in high capacity connections allows for:

  • Carrier-grade signal availability as high as 99.999 percent.
  • Fully licensed secure connections with built-in hardware security configurations and optional software encryption overlays that provide inherent privacy protections.
  • Macro cell and small cell backhaul connectivity to underserved poles, towers and buildings, typically 0-to-3 miles away via line-of-sight links.
  • Environmentally efficient solutions that often involve less disruption to road and earth surfaces.  Large numbers of broadband connections within dense urban campus areas, or a broadband supply line to a rural structure.
  • Spectrum usage authorizations within a short time period (weeks or months).
  • Economically viable broadband solutions for customers.
  • Reach unserved and under-served urban or rural locations: Service to a location where wireline, fiber, or another technology may not be technically or economically available. Examples, (i) bringing WiFi and broadband to an overlooked building or lightpole in an urban area; (ii) reaching across a railway or a river, where trenching or other obstacles exist. 

5G Mobile Access and Future Use

  • The wide-area licensed 24GHz band has also been validated for future broadband mobile access by numerous standards bodies, including technical studies and trials published by the IEEE Microwave Theory and Techniques Society.  5G networks using millimeter wave bands may offer 1Gbps to mobile handsets by 2020 [Sources: IEEE, Samsung, FCC].  
  • FiberTower Labs conducted the nation’s first successful 24GHz mobile and non-line-of-sight tests in early 2015 and published the findings in the ongoing Above 24GHz Mobile Broadband Notice of Inquiry (NOI) before the Federal Communications Commission.
