what has been happening in osmo-small-hardware.git

osmo-rfds is a small project that is used to introduce configurable delay into an actual RF path. This is used e.g. to simulate propagation delay and test timing advance control loops in Osmocom GSM.

Introducing a small tool that can be used to manage incremental changes to libosmocore/vty-style configuration files. How it works + quick demo

Recently, we introduced a SGs interface to osmo-msc for CSFB and SMS interoperation with 4G/LTE. This talk covers SGs interface basics as well as how we added it to osmo-msc

In Q2+Q3 2019, the speaker is working on a [funded] project to implement proper Cell Broadcast support in Osmocom. Let's cover the current status and the goals for this project, including

• a proper OsmoCBC
• 3GPP standard interfaces between CBC and BSC
• OsmoBSC side scheduling of SMCB
• 3G support for SABP (Service Area Broadcast)
• Tools for easy generation of standard messages, particularly ETWS/CMAS/WEA/EU-ALERT/...

Recently an external interface for SS/USSD was introduced. This time I am going to present an alternative (to SMPP) way of forwarding SMS messages between the Osmocom CNI and SMSC (Short Message Service Center) or some ESME (External Short Messaging Entity).

Let's cover how the Osmocom GSM + 3G test network worked @ 35C3

This talk covers Inter-MSC hand-over both on the conceptual side, as well as the osmo-msc implementation.

How we put all pieces together in osmo-gsm-tester to have (E)GPRS tests for different scenarios. Issues found during the process, fixes and workarounds.

What do we need to do in order to operate a 4G/LTE network that's integrated with Osmocom 2G/3G?

Let's have a bit of a run-through on the nextepc software architecture (threads, libraries, ...) to understand what's similar and what's different from the Osmocom CNI projects

In this talk we're going to cover the possibilities to receive higher (satcom) bands with a reasonable budget.

I would like to share my progress in porting layer1 to fernvale (MediaTek 626x chipset) and discuss how best to proceed with the goal of getting layer1+nuttx+mobile on fernvale as well as related devices like sim800[A-Z] and dz-09 like watches. Possibly also discussing newer chipsets like mtk6735/6737 (zte obsidian and orange pi 4g/iot board).

Since the first osmo-remsim tag has been pushed to the repo on April 1st (no April fools joke!), let's have a look at the software, it's capabilities, configurations and architecture

Let's grow the web of trust and do some gpg keysigning among Osmocom developers

Review of the Mobile Networks in Oaxaca

In this talk we will present the system we used in the HERMES (High-frequency Emergency and Rural Multimedia Exchange System), winner of the Off-the-Grid Internet Challenge of Mozilla WINS Challenge.

At HERMES demonstration in Mexico the system was composed by a couple of ICOM IC-7100 radios (100W peak output power), doing NVIS (Near Vertical Incidence Skywave) skywave communication between a community in the mountains and capital of the state. An SDR modem designed to be used with standard HF transceivers, and the software to connect everything (including the Osmocom GSM stack) together with a GSM BTS were assembled to provide emergency communication to any isolated place.

Let's finalize the schedule

Because we couldn't find any decent multi-slot SIM card (e.g. smart card) reader, we decided to build our own: the sysmoOCTSIM.
This use the recent Microchip SAM E54 micro-controller, which is only supported by the Atmel START web-based IDE.
We will briefly present the sysmoOCTSIM and how to get started with Atmel START.

The EU decided to switch to harmonized shipping labels, but no one seems to have implemented it yet. This is my simple try.
