Osmocom Conferences (OsmoDevCon, OsmoCon, OsmoDevCall)

we're happy to announce the next incarnation of OsmoDevCall.

This time, falconia will be presenting on Calypso chipset history and development boards, from TI to FreeCalypso

When: Wednesday, November 15, 2023 from 20:00 CET

Where: https://osmocom.org/OsmoDevCall (Big Blue Button of https://franken.de/)

We're happy to announce that our recorded presentations of OsmoDevCall are now also published in our new @osmodevcall@tube.tchncs.de peertube¹ channel. A peertube channel has the advantage that it can be subscribed by interested people, as long as they have a user account in any fediverse/mastodon instance.

¹ Peertube is a federated, open source video sharing system built on Open Source Software using the ActivityPub protocol many people know from Mastodon. See https://joinpeertube.org/ for more information about it.

we're happy to announce the next incarnation of OsmoDevCall.

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.

we're happy to announce the next incarnation of OsmoDevCall.

This time, falconia will be leading a discussion about FR/HR/EFR voice codecs in Osmocom RAN

When: Wednesday, June 21, 2023 from 20:00 CEST

Where: https://osmocom.org/OsmoDevCall (Big Blue Button of https://franken.de/)

we're happy to announce the next incarnation of OsmoDevCall.

This time, laforge will be presenting on Circuit Switched Data (CSD) in GSM

CSD is the mechanism by which circuit-switched data calls can be made over classic GSM/2G (and later also UMTS/3G) networks. They resembled the modem call of circuit-switched networks, but of course no voiceband modem is involved.

For more information, see our CSD wiki page.

This time, tsaitgaist will be presenting on USB hub for device testing.

When: Wednesday, December 21, 2022 from 20:00 CET

Abstract:

During hardware development and testing you often have numerous additional devices attached to it: serial debugger, programmer, logic analyzer, and so on.
A commercial USB hub should be enough handle that, but it often comes with limitations.
So why not have a USB hub designed for assisting in hardware development and testing: flat 7 ports, impedance controlled, with current and ESD protection, and remote power control for USB and higher voltages.
The result is open source and available at https://git.cuvoodoo.info/usb_hub.
