Deutsche Telekom, in collaboration with infrastructure partner Crown Castle, and vRAN solution vendor Altiostar, is building an ultra-low latency mobile testbed at Carnegie Mellon University (CMU) in Pittsburgh as part of the Open Edge Computing Initiative.
DT said the Edge Computing setup combines a fully software-enable network with a modular Radio Access Network (RAN) platform. The wireless access in the 3.5GHz band leverages advanced LTE and 5G features such as Massive MIMO, Active Antenna Systems (AAS), and beamforming technology by Airrays, a German radio vendor, and is powered by vRAN (virtual RAN) technology by Altiostar.
The vRAN solution uses an innovative method to connect the AAS panels with the virtualized baseband unit (vBBU), a performance-optimized NFV platform running on Commercial off the Shelf (CoTS) hardware inside the CMU campus alongside the Edge Computing server “Cloudlet”. Connectivity to each site leverages extensive fiber optic networks owned and maintained by Crown Castle.
