+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.
