Related vehicles utilizing know-how from the worldwide know-how group Giesecke+Devrient (G+D) are equiped with two eSIM playing cards: one is used for eCalls, navigation or site visitors data providers, the opposite for the driving force’s non-public data and leisure providers.
The technical base is G+D’s DSDA resolution (Twin-SIM Twin-Lively) and AirOn360 eSIM administration platform. These options are additionally used within the BMW iX and BMW i4 and shall be accessible in different new BMW Group fashions sooner or later.
Most often, connectivity is offered by the SIM modules which might be already factory-installed in good gadgets similar to smartphones, smartwatches and good house gadgets. Trendy autos additionally get outfitted with this know-how. These so-called embedded SIMs (eSIMs) have been made obligatory since March 2018 within the EU as a result of their computerized emergency name system, eCall.
In terms of linked vehicles, G+D is now taking it one step additional along with the BMW Group, because the autos shall be outfitted with two unbiased eSIM modules. The idea is the DSDA idea, which is now market-ready and takes a user-centric method to connectivity. The so-called telematics eSIM ensures the producer’s digital providers similar to eCall, navigation or site visitors data, whereas the non-public eSIM is used for data and leisure functions of the driving force and their passengers.
G+D’s DSDA resolution is applied within the BMW iX and the BMW i4 and also will be accessible for different BMW Group fashions sooner or later. Non-public digital providers within the car can be utilized by passengers in parallel with car-to-cloud communication for BMW Group telematics providers. A second cell connection is established for the non-public eSIM, whatever the community supplier utilized by the automotive producer to supply its providers.
The motive force has thus instantly entry to all cell providers similar to video or music streaming. A further benefit is the huge performance of the eSIM: A number of private eSIM profiles might be saved in order that your complete household may entry their non-public digital providers when utilizing the automotive.
The DSDA resolution and eSIM profile provisioning and administration are dealt with by a single, unified resolution: the AirOn360 eSIM administration platform from G+D. It helps safe lifecycle administration of eSIMs. The platform complies with all specs for distant SIM provisioning set by the GSMA. Through the use of trendy IP-based IT structure requirements and protocols, there’s a totally owned eSIM provisioning assure.
The brand new resolution gives a number of advantages to each automotive producers and consumers. Producers can provide infotainment and telematics providers to their clients through a central eSIM administration platform, with separate accounts, tariffs and cell connections. For consumers, the DSDA resolution brings non-public connectivity to the automotive.
This separation of networks additionally facilitates the trail to assembly the completely different regulatory necessities in lots of international locations. That is particularly related, for instance, when issuing telecommunications licenses for consumer-oriented ISP providers (Web Service Supplier providers) or for M2M and telematics providers.
Final however not least, because of the DSDA precept, the beforehand frequent however pricey Bluetooth pairing of the smartphone with the car, turns into redundant. That is essential, for instance, for the usage of the hands-free system. There are a number of issues related to Bluetooth pairing. First, the producer should guarantee Bluetooth compatibility of the car with quite a lot of completely different cell gadgets and software program variations. Second, with this method, transmission and reception high quality is compromised by car shielding as a result of the cell system’s antennas are used. With DSDA, alternatively, the exterior car antenna is utilized, which ensures excessive sign high quality.
Carsten Ahrens, CEO of G+D Cellular Safety, emphasizes:
“Right now’s drivers have completely different expectations of a automotive than prior to now. They depend on navigation techniques with all the time up-to-date maps and site visitors data, wish to devour multimedia web content material, work and make telephone calls within the automotive, or seek for the following free charging station. Which means that trendy infotainment techniques should permit versatile personalization based mostly on person profiles that additionally regulate entry to the web within the automotive.”
“We’re happy that G+D has been the answer associate for the BMW Group within the space of eSIM for a few years – and now additionally for the brand new Twin-SIM Twin-Lively resolution. Collectively, we’re creating the essential requirement for a brand new type of individually networked mobility.”
