Why is the integrated eSIM technology a paradigm shift in IoT product development?
eSIM integrated cellular modules from Cavli will enable IoT product makers to operate at scale
Mobile M2M applications, especially those that are applied globally, are burdened by the fact that SIM card management can be very complex, resulting in significant administrative procedures and costs for large-scale applications in the field. However, the use of the C1RM with an integrated eSIM card brings significant benefits and offers users the ability to change service providers over the air, without having to physically replace the SIM card itself, or phones. eSIM represents the most radical change in the last two decades of GSM connectivity, meaning the C1RM users can choose and change the profiles or service providers globally, in accordance with their needs.
Directly embedded into the C1RM, the eSIM is remotely reprogrammable, so the management of its subscription credentials is not so complex anymore. Besides, benefits are also cost optimization of large scale M2M projects which will not need to worry about the delayed launch of NB IoT networks. Get started on 2G and seamlessly switch to NB IoT when the time comes.
The production of any smart device involves the primary expertise of a chipset manufacturer who produces the device’s connectivity hardware module and OEMs & ODMs who finally manufacture the smart device. Their role has always been essential but limited until eSIM appeared on the market. eSIM capability became very important and is affecting some new relations and partnerships. When an OEMs/ODMs buy, C1RM with integrated eSIM - that package includes instant connectivity. C1RM with integrated eSIM enables OEMs/ODMs to establish a direct relationship with the customers because e-SIM allows it.
“Furthermore, C1RM with integrated eSIM gives an opportunity to develop and implement more features using the space previously occupied by traditional SIM cards like storage, battery capacity, environmental resistance improvements, and smaller module/modem dimensions.”
The general conclusion is that C1RM with integrated eSIM technology helps OEMs/ODMs benefit from cost effective global IoT connectivity, improve their position in the market, and develop new relations with customers.
How C1RM can enable telecom operators for LPWAN network planning?
Unconditional connectivity is of the utmost importance for the IoT landscape. One of the NB-IoT’s crucial performances is the indoor coverage and makes it an optimal solution for scenarios where other wireless technologies are facing problems. This feature of NB-IoT technology fulfills and exceeds expectations when compared to traditional cellular wireless technologies, such as 2G/3G/4G. It especially becomes important inside buildings, in basements, garages, underground facilities, etc.
Penetration Stats of NB-IoT networks as on Sep 2020
At the same time, 2G technology with a typical link power of around -113dBm is still present in many countries, regardless of the facts it is power consuming and mostly overcome compared to other 21st century wireless technologies.
C1RM is an effective solution capable of bringing IoT connectivity to the existing 2G or LTE CAT NB-IoT networks. Supported LTE CAT NB radiofrequency Bands are 3/5/8/20/28 and quad radio frequency bands for GPRS. Operating modes according to the available frequencies are In-Band, Guard Band, and Standalone. In compliance with national regulations, this feature is very important to meet the customer needs in congested Smart City areas or rural areas where network infrastructure and coverage can be limited.
The C1RM decision between NB-IoT or 2G connectivity is correlated to the available network coverage. Together with Cavli Hubble, APIs are available for analysis on what percentage of time the C1RM is connected to NB-IoT or 2G. This C1RM feature presents a significant and powerful tool for mobile operators to perform cost-effective field tests and real-time network coverage measurements or to plan its further development. C1RM is ensuring user-friendly and cost-efficient network deployment and management through Cavli Wireless proprietary cloud platform - Cavli Hubble.
Fallback option to 2G helps accelerate agricultural IoT
Although obsolete, 2G technology is becoming significant again and interesting in terms of data transfer capabilities for IoT and M2M communication in many countries worldwide. Considering the fact that C1RM is not only on standard NB-IoT but also the GPRS module/modem, it could be interesting for many companies deploying and relying on 2G based solutions for M2M communication.
Challenges for IoT deployment in agriculture and farming are represented usually in rural regions without state-of-the-art technology network infrastructure. Also, farmers’ investments into new IoT systems, in the best case bring additional installation costs and often are unaffordable.
