2023-03-15: Circuit Switched Data in GSM

Added by laforge about 1 year ago

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.

2022-12-21: USB hub for device testing

Added by laforge over 1 year ago

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

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.

2022-11-16: MS/BS power control support in OsmoBSC/OsmoBTS

Added by laforge over 1 year ago

we're happy to announce the next incarnation of OsmoDevCall. Based on the recent polls, the timing has shifted to every 3rd wednesday of the month.

This time, fixeria will be presenting on MS/BS power control support in OsmoBSC/OsmoBTS.

For those not entirely 3gpp-acronym-savyy: That's how the uplink (phone -> network) and downlink (network -> phone) transmit RF power level is adjusted during an active call in GSM.
