*When*: today, 12pm-1pm
*Where*: CSE2-271
*Who*: Kurtis Heimerl
*Title: *CoLTE, a LTE-based community networks solution

*Talk Summary:*
In this talk I introduce CoLTE, a solution for LTE-based community
networks. CoLTE is a lightweight, Internet-only LTE core network (EPC)
designed to facilitate the deployment and operation of small-scale,
community owned and operated LTE networks in rural areas with limited and
unreliable backhaul. The key differentiator of CoLTE, when compared to
existing LTE solutions, is that in CoLTE the EPC is designed to be located
in the field and deployed alongside a
small number of cellular radios (eNodeBs), as opposed to the centralized
model seen in large-scale telecom networks. We also provide performance
results and lessons learned from a real-world CoLTE network deployed in
rural Indonesia. This network has been sustainably operating for over
six months,
currently serves over 40 active users, and provides measured backhaul
reductions of up to 45% when compared to cloud-core solutions.
