Demonstration leverages Verizon’s expansive mmWave spectrum holdings and fibre infrastructure to reach multiple end user connections from a single origination location.
Verizon has completed a proof of concept in Texas showcasing a new multi-unit internet solution which could expand the addressable homes and businesses that can be served with its vast mmWave spectrum holdings. Specifically designed for multi dwelling units (MDUs) (such as apartment buildings and townhomes) and distributed enterprise campuses and high rises, this point to multipoint architecture leverages Verizon’s mmWave high band spectrum holdings, owned fibre infrastructure and existing Intelligent Edge metro and core infrastructure to provide reliable, secure, multipoint connections from a single donor cell site. The recent demonstration showcased an architectural design that is less expensive to build, quicker to deploy, and addresses the unique complexities of distributed end users in a single facility or small area such as a residential unit with a large population.
In this proof of concept, an airlink over licensed mmWave spectrum was established between a centralized, rooftop radio site and a radio atop a simulated multi end-point building. The signal was then transmitted via coaxial cable throughout the building to a data processing unit along with a corresponding modem. From there, the building’s existing wiring transported the signal to end user routers that provided broadband coverage throughout simulated distributed end points. Instead of transmitting the data through Verizon’s 4G and 5G wireless cores, this unique architecture uses a simplified Broadband Network Gateway to direct the traffic to and from the internet over Verizon's public IP network. This means that data traffic will not add load on Verizon’s current wireless cores while at the same time providing excellent capacity and latency.
“Verizon has been building the infrastructure and assets for years to make this new design possible,” said Adam Koeppe, Senior Vice President of Technology Planning for Verizon. “Leveraging our significant fibre footprint in over 70 major markets nationwide and large amounts of ready-to-use mmWave spectrum, this new architecture means we will be able to provide point-to-multipoint architecture in a cost effective and efficient way.”
Leveraging Verizon’s current mmWave spectrum and fibre assets means this point-to-multipoint technology could reduce the cost of providing broadband to many locations. Depending on the various designs of buildings, office complexes and campuses, running fibre connections to individual buildings and individual units within buildings requires complex licensing, significant capital investments, long lead times and can be disruptive, making air links and established indoor cabling appealing alternatives for delivering services. Applications for this type of point to multipoint mmWave based technology could include distributed enterprise campuses, commerce areas, home broadband for multi dwelling units or other areas where air links could easily connect donor sites in the Radio Access Network to facilities with their own internal infrastructure.
Verizon is completing RFPs for the specialised radio access equipment for the licensed 37-39 GHz spectrum and expects to continue developing this technology throughout the year.
