In March 2020, Internet2 and several of its members established the Future Wireless Working Group to explore areas of collaboration regarding the use of emerging wireless technologies on campuses and across the R&E community. The focus of the group has been the recently commercialized Citizens Broadband Radio Service (CBRS) spectrum and its use by campuses. CBRS presents, for the first time, the opportunity for campuses to own and operate fully private LTE and soon 5G mobile and fixed wireless broadband networks (much like they run private Wi-Fi networks) without the needfor
to spend on expensive spectrum licenses. This was made possible by the FCC’s adoption of a shared access model for the 150 MHz of mid-band spectrum (3550 MHz to 3700 MHz)assigned to the band
between commercial and Federal/DoD incumbent users.
The shared model employs dynamic spectrum management to mitigate contention across three tiers of priority. The highest priority is for Incumbent Access (IA) users of the spectrum (primarily US Navybases
radar systems) followed by Priority Access License (PAL) auction winners, which are granted interference protections for 70 MHz of the 150 MHz, and capped up to 40 MHz each, and lastly, General Authorized Access (GAA) users.The spectrum management
While GAA users are not provided with any interference protections, their access is coordinated by a cloud-based spectrum access system (SAS). This spectrum management and coordination is performed byone of the five
FCC approved Spectrum Access System (SAS)providers via hosted web services
administrators via cloud-based systems and include companies such as Amdocs, Commscope, Federated Wireless, Google and Sony. Each university private CBRS network operator would register their network with a single SAS administrator in order to gain access to CBRS spectrum. SAS registration and fees apply and entails commercial agreements with each SAS administrator.
Private LTE networks provide a full mobile and fixed wireless experience including Quality of Service (QoS), seamless high-speed hand-offs, hardened security (SIM cards), low latency, longer range and less power consumption versus Wi-Fi. These capabilities allow campuses to support a full range of mission critical applications, extending their networks to remote locations, improved indoor and outdoor wireless coverage, support research activities, and potentiallydevelop new roaming and
neutral host network access and macro off-load business models with traditional and emerging Mobile Network Operators (MNOs) and Cable Mobile Virtual Network Operators (MVNOs) .
This working group hosts topical discussions as well as meetings with key ecosystem participants including SAS providers, CBRS equipment providers and managed service providers, with the goal of providing community recommendations and actions.
This group has three sub groups with different focuses:
- Future Wireless Working Group Business Subcommittee: focused on recommendations around business and financial models.
Areas of Focus:
- Identification of opportunities for university and higher education collaboration on pursuing new CBRS enabled business models, including Private LTE roaming across campuses, and CBRS neutral host networks.
- Establishing objectives and value propositions based on CBRS private networks that address university and higher education strategic research and development objectives, while enhancing wireless network coverage and quality in support of smart campus initiatives.
- Engaging with carriers and service providers to plan and conduct proof of concepts for solutions such as neutral host network access and in the future network-to-network roaming.
- Maintaining ongoing business development and engagement with mobile operators and other service providers to enhance prospects for future collaboration and business relationships on CBRS and other emerging wireless technologies.
- Future Wireless Working Group Technical Subcommittee: focused on recommendations around technical solutions.
Areas of Focus:
- Review of university and higher education institutions use cases and technical capability requirements.
- CBRS technical planning and requirements development in support of proof of concepts such as Private LTE/5G roaming and neutral host network access.
- 4G and 5G technology assessments and recommendations.
- Meetings with CBRS technology vendors to deepen and expand understanding of private LTE/5G equipment and software capabilities and limitations.
- NET+ Future Wireless Advisory Group: focused on potential brokered service cloud offerings in the CBRS and/or 5G spaces.
