sysmocom moving office / no shipments April 7-20, 2024

sysmocom moving office / no shipments April 7-20, 2024

As sysmocom will be moving our office (including warehouse), there will be no order processing between April 7th and April 20th, 2024. Due to the general impact on our operations, we also expect that responses to inquiries will be slower than usual around the time of the move. Thanks for your kind understanding.

Any orders of in-stock products placed before April 7, 9:00 am (CEST) will still be processed before the move. Orders placed at a later point in time can only be processed after the move has completed and we're fully operational at the new address (expected on April 20th).

Our new postal address after the move is Siemensstr. 26a, 10551 Berlin, GERMANY. All suppliers and business partners will be informed separately.

sysmoNITB Starter Kit with multi RAT support


sysmocom announces the new sysmoNITB Starter Kit with support for 2G, 3G and 4G basestations at the same time.

The sysmoNITB Starter Kit is well known for lab usage. In the last years, we received multiple requests to support more than one RAT and even to support 4G. Now we are able to fulfill these requests. On the sysoNITB you find the well known Osmocom Software and - if 4G is selected - Open5gs, completely configured for the basestations which are ordered within the sysmoNITB Starter Kit and with commisioned SIM cards, so the Starter Kit is ready to run within a very short time.

With the sysmoNITB Starter Kit all permutations of basestations together with a singe core network and single HLR are possible. This helps you in development, test and monitoring of UE in lab environments. For existing customers of the sysmoNITB, an upgrade to an additional RAT is possible. Contact us for further requests.

New Product: sysmoISIM-SJA5


sysmocom announces the availability of its latest generation of programmable/customizable SIM card products, the sysmoISIM-SJA5.

The sysmoISIM-SJA5 is the successor over the earlier sysmoISIM-SJA2.

The update from SJA2 to SJA5 means that under the hood there is a new smart card chip and a new smart card operating system, as well as an updated profile, in-line with 3GPP Release 17. The card now also supports the 3GPP HPSIM application, in addition to the ISIM, UISM and classic GSM SIM applications.

The new card is available in two different variants: 9FV and S17. The S17 option differs from the 9FV option in that it supports the best available 5G security/privacy feature SUCI calculation by the USIM. Using that feature, the concealed subscriber identifier (SUCI) can be computed entirely on the card itself, with the related key material must never leave the secure smart card. The lower-cost 9FV variant only offers SUCI calculation by the ME, where the related key material must be readable and hence is more easy to compromise.

sysmoISIM-SJA5 in 2FF/3FF/4FF form-factor is already shipping to our bulk customers with made-to-order volumes from MOQ-1000 upwards. Individual samples are available upon request. General availability of sysmocom-branded 10-packs in the webshop is expected to start in December 2023.

At the same time, the predecessor sysmoISIM-SJA2 is end-of-life (EOL). We are still selling remaining stock until it runs out, but there will be no more production runs of this old product.

For more information about the sysmoISIM-SJA5, check its product page.

New sysmocom webshop goes live

sysmocom is happy to announce that the new sysmocom webshop has gone live today.

A major re-launch of our ancient "web 1.0" was long past due anyway, but the specific reason for this re-launch was the change of shipping methods that was forced upon us by Deutsche Post, the German postal company.

During the past decade, we always could offer exceptionally good shipping rates for our mostly very small/lightweight products to our global customer base. This was possible by shipping the products as registered mail. The disadvantage was very long delivery times, particularly for our (majority of) intercontinental customers.

However, from today (July 1, 2022), Deutsche Post and its subsidiary DHL discontinued the related shipping options. They are now only offering unregistered (no proof of delivery) postal shipments, and with no liability for loss and damage anywhere near our product value.

As a result, we had the choice between the rather expensive postal package (which is also relatively slow) and the industry-standard express shipment providers. We decided to go for UPS, which has been the preferred shipping partner for our enterprise (non-webshop) product shipments for a long time.

The new webshop now offers UPS Express Saver, and depending on the destination possibly the more economic UPS Standard and/or UPS Expedited options.

In terms of payment methods, the new webshop now adds Stripe as a payment provider next to Paypal. This enables direct payment via credit cards, as well as a number of country-specific payment options like SEPA Direct Debit and giropay (Germany), P24 (Poland), EPS (Austria), SOFORT (Belgium, Germany, France, UK, Italy, Netherlands, Austria, Poland, Switzerland, Spain, Czech).

New Product: MFF2 ZIF Adapter


sysmocom announces the availability of the new MFF2 ZIF Adapter, an adapter to use MFF2 SIMs in regular SIM slots.

As Machine Form Factor (MFF) SIMs - which are usually soldered directly on devices PCB - are gaining more and more momentum in IoT, sysmocom reacted on the demand for an adapter to test, debug and analyze such SIMs with existing tools like our SIMtrace board but also other devices with usual SIM card slots.

The Adapter offers the same FPC connector as our SIMtrace board and uses the same adapter cables (not included).

The MFF2 ZIF Adapter is in stock and can be ordered via the sysmocom webshop.

New Product: Osmocom icE1usb


Today, sysmocom announces the availability of the Osmocom icE1usb, an E1 USB interface.

With it's built-in GPS-DO, the Osmocom icE1usb can provide a highly stable reference clock, which is for example required by most legacy GSM/2G base stations from major vendors such as Ericsson, Nokia and the like.

Osmocom icE1usb is 100% Open Source Hardware and requires no special-purpose silicon ICs like E1 framers or line interface units, which are increasingly difficult to source as E1/TDM technology is becoming more of a niche.

The icE1usb are in stock and can be ordered via the sysmocom webshop.

New Product: sysmoISIM-SJA2


After many years of supplying the world wide community of cellular researchers, academia and operators of private cellular networks for many years with the programmable SIM card sysmoUSIM-SJS1, it is time for a change:

Today, sysmocom announces the availability of the sysmoISIM-SJA2, the successor product to the sysmoUSIM-SJS1.

The major improvements include:

  • ISIM application for IMS/VoLTE (in addition to SIM + USIM applications)

  • pre-installed ARA-M applet for use with Android Carrier Privileges

  • only one product covering 2FF, 3FF and 4FF form-factor

  • All 3GPP-specified 5G related files on card

The new card of course includes all of the major features of its predecessor, such as:

  • modification of the contents of any file in the SIM, ISIM, USIM application (using AMD pin)

  • modification of key material, selected authentication algorithm and related parameters (using AMD pin)

  • installation of Java applets via GlobalPlatform SCP02 or TS 03.48 OTA

  • remote file management via TS 03.48 OTA

sysmocom has already ported the pySim and sysmo-usim-tool software, so both fully support the sysmoISIM-SJA2.

The cards are in stock and can be ordered via the sysmocom webshop

New Product: M.2 WWAN modem breakout board


More and more modern cellular modems are being released not in the classic miniPCIe form-factor, but in M.2 (NGFF). Particularly for LTE-Advanced and 5G/NR, this is a requirement as only M.2 has USB 3.0 and a PCIe lane for higher connection speeds to the host processor.

Following the success of sysmocom’s miniPCIE WWAN break-out board, we have now released a M.2 WWAN modem break-out board. It can host any M.2 cellular modem and exposes not only the USB 3 super-speed signals, but also the PCIe lane. With the included cable and PCIe adapter, it can be connected to any PCIe x1 slot in a PC or embedded computing board.

To read more information about the M.2 WWAN modem breakout board, please visit the product page.
