Announcing the low-power, light-weight sysmoBTS
It hasn't been a secret that when I co-started a company called sysmocom more than a year ago, it was not about opening a webshop that sells cheap phones and DYI electronics kits to the larger community. Rather, it was to develop and sell exciting products surrounding Free Software and mobile communications.
There are of course the more or less obvious things to do, like system integration of OpenBSC and the related software on embedded systems, selling them as appliances including training, support and maintenance service.
However, we of course also want to more than that. Today it is my pleasure to say that the availability of our first BTS product called sysmoBTS has been officially announced.
To make it very clear in the beginning: sysmoBTS is not an open hardware project. The schematics and layout files are proprietary and not disclosed publicly. Such is the FPGA bitstream and the layer1 inside the DSP.
However, any code running on the integrated ARM processor is available as free software. This includes a yocto/poky-built Embedded Linux distribution featuring u-boot, the Linux kernel (including all kernel modules!), the osmo-bts and OpenBSC software as well as many other Free Software packages.
We think this is a reasonable compromise between espanding a bit from our previous "BSC and above in Free Software" down to a "BTS Layer2 and above" divide. After all, if you use OpenBSC with a BTS from Siemens, Ericsson, Nokia or ip.access, you don't have access to the source code of anything running inside the BTS at all.
sysmoBTS offers some great new capabilities, such as integrating the BSC or even the entire osmo-nitb onto the ARM/Linux processor inside the BTS hardware itself, creating a less than 500gram, 10W power consuming autonomous GSM network.
I'm going to stop marketing here, but I thought it is one of the major milestones for sysmoocm and thus for what I've spent way too much time on in recent months - and thus deserves to be mentioned here on this personal blog.
