Community Networking Toolkit This is a toolkit/resource guide for anyone interested in starting up their own community network. Hi my name is blah blah Ethernet Crimping Ethernet crimping is an important skill for network site installations. The length of an ethernet cable connection is only truly known once you're on site so it is useful to be able to quickly cut ethernet cable to the desired length and crimp it.

EPC Installation and Setup The CoLTE package runs on Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 20.04 LTS (Focal Fossa), or Debian 10 (Buster) 64-bit version. Install is tested on a fresh Ubuntu Desktop or Ubuntu Server installation. This tutorial assumes that the install is being performed on an x86-based mini-PC. Note: You should choose the “basic install” option that doesn’t install extra unnecessary software. In prior installs this has led to version conflicts. I. LTE Architecture CoLTE simplifies implementation and configuration of the Evolved Packet Core (EPC) elements of an LTE network using the Open5GS package. The EPC provides Control plane functions, such as subscriber and mobile management, and User plane functions, such as routing user traffic to the internet. It connects to the radio base station, known as the eNodeB, which in turn will associate with User Equipment (UE).

eNodeB SAS Setup Introduction Despite CBRS being a relatively open frequency band, the processes for spectrum access are still somewhat opaque and require significant capital investment and/or ISP-level resources to set up. To clarify this process, here’s a step by step walkthrough tutorial of the setup of a Baicells eNodeB (eNB) base station running in the Citizen’s Broadband Radio Service (CBRS) spectrum band (or band 48). Before following this tutorial, you should have completed the setup of a LTE Evolved Packet Core (EPC) to control your eNB, for which the setup of an open source version based on open5gs is outlined in this tutorial. I. Get set up with a Spectrum Access System (SAS) A. Why get set up with a SAS? Current FCC regulations require all CBRS equipment (called a CBSD) to be registered on a Spectrum Access System (SAS) that coordinates all spectrum assignments and ensures that no transmissions interfere with each other. This will likely require a commercial agreement with a SAS provider such as Google, Federated Wireless, etc. This tutorial uses the Google SAS.

Documentation Hello and welcome to the documentation website for Seattle Community Cellular Network! About Seattle Community Cellular Network We are a community network dedicated to providing fair access to underserved communities all across the Puget Sound. SCCN is a 501(c)(3) registered non-profit in partnership with the University of Washington (UW) that shares free or low-cost broadband access in higher-need areas throughout the city, making use of existing UW and city network infrastructure such as buildings and fiber-optic cables to extend coverage to more people. As a community network, we rely on the help of city residents such as yourself to maintain and grow the network. Joining us is a great way to become an active member of your own community, make friends, as well as learn valuable technical skills. Ask questions in our Slack chat and connect with our other volunteers or join our mailing list. About This Website The SCCN Docs website is the central hub for technical information about our network. Here, we describe the implementation of specific nodes, document installation procedures, and more. Readers are expected to have some basic familiarity with computer networking concepts in order to fully understand the material we cover, but we do try our best to provide links to good educational resources for new volunteers.
