OsmoDevCall on Jul 17, 2023: Building wired cellular test setups
by Harald Welte 17 Jul '23

17 Jul '23

Dear Osmocom community, we're happy to announce the next incarnation of OsmoDevCall. when: July 17, 2023 at 20:00 CEST where: https://osmocom.org/OsmoDevCall (Big Blue Button) This time, @laforge will be presenting on Building wired test setups for mobile communications Particularly in lab and test setup involving cellular technology there is often a need for wired (coaxial) connection of cellular equipment, such as connecting a number of UEs (phones/modems) with one or multiple cellular base stations. For example, this is the only way to get defined power levels and test the actual transmit power or receive sensitivity of a device. The talk will cover how to build such test setups from parts like coaxial cabling, attenuators, RF splitter/combiners, duplexers, etc. This meeting will have the following schedule: 20:00 meet + greet 20:10 topic as outlined above 21:00 unstructured supplementary social event [*] Attendance is free of charge and open to anyone with an interest in Osmocom or open source cellular technologies. More information about OsmoDevCall, including the schedule for further upcoming events can be found at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCall Looking forward to meeting you soon! Best regards, Harald [*] this is how we started to call the "unstructured" part of osmocom developer conferences in the past, basically where anyone can talk about anything, no formal schedule or structure. -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
