Dear Osmocom community and friends, Next week on September 10, I will be presenting a talk about cellular base station technology as part of the "Datengarten" series of talks at Chaos Computer Club Berlin (CCCB). The talk will focus on actual base station hardware as it evolved during the last 20 years or so. It will not assume much in terms of protocol stacks or cellular architecture, but more focus on the hardware building blocks. More information can be found at https://berlin.ccc.de/datengarten/102/ The event is public, so feel free to invite anyone along whom you think might be interested. Regards, Harald --- Abstract In today’s hyper-connected society, everyone constantly uses their smartphone, which in turn uses the commercial cellular networks (from 2G/GSM to 4G/LTE) in order to achieve connectivity. However, contrary to WiFi technology, even most technology-minded people don’t have much of an idea how the infrastructure behind those cellular networks looks like. This talk does not cover the architecture and protocols of underlying cellular systems, but focuses on the physical side of things: * what are the typical components of cellular base stations? * what are their key functionalities? * how did cellular base station technology evolve during the past 20 years? * how do we expect cellular base stations to change in the [near] future? We will not cover DIY or hobbyist projects here, but the actual technology deployed in the field by real-world commercial operators. --- -- - Harald Welte <laforge@gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
