Virtually all current cellular IoT applications use one of two technologies: LTE-M or NB-IoT. The takeaway for you is that although there are important, application-specific distinctions between the two kinds of cellular IoT, generally, you choose one or the other depending upon whether LTE or GSM cellular infrastructure is the standard in your region. Only the US, Netherlands, Ireland, and Australia have national LTE coverage, while GSM is standard in many non-Western regions like Eastern Europe and Africa.
cellular IoT will benefit the value chain for the following:
Open standards based on existing infrastructure allows coverage of virtually everywhere where people live, people or devices will stay connected all the time, especially in 5G era.
IoT connectivity of many devices at the same time allows smarter operation for digital transformation of enterprises in the LTE standard and licensed-band operation.
Upload and download rate is not limited by some regulatory regulations, more space for innovation and user experience of cloud-managed service.
Standard TLS/DTLS security for end-to-end security is supported on top of the on-air encryption of the LTE network aided by the SIM credentials. This keeps data secure from the device to the cloud server
As cellular networks already cover 90 percent of the world’s population and can now be offered in low complexity, low power variants, cellular technology is a great choice for the world’s IoT needs, both now and in the future.
Massive IoT is, as the name suggests, a category driven by scale rather than speed. Massive IoT deployments can include anywhere from hundreds to billions of connected devices. The primary goal for these applications is to efficiently transmit and consume small amounts of data from vast numbers of devices.
Massive IoT applications are a natural fit for low-power wide-area networks (LPWANs). These cellular networks match the requirements of a massive IoT deployment and, crucially, can be built on existing advanced LTE technologies like LTE-Machine (LTE-M) and Narrowband IoT (NB-IoT), which utilize narrower bandwidths optimized for low throughput applications. Low data flows currently work with 2G, 3G and 4G cellular networks and will only further the capabilities of 5G when it becomes widely available.
In the 5G era, there are massive devices needed to connect to mobile networks. The existing SIM card technology has several problems which become a hurdle for fast and massive IoT deployment. RedteaSIM is a lower-cost, higher-efficient, and equally secure alternative to the traditional SIM card to meet the growing demand for large-scale IoT deployment, particularly suitable for massive IoT application (LPWAN, NB-IoT and Cat-M) requiring a long battery life and only small amounts of data. Unlike the traditional SIM card, which has been an additional piece of hardware inserted or soldered into IoT devices. RedteaSIM transferrs the functions of the classical SIM card directly into the communication chip.
For IoT connectivity part, With traditional SIM for connectivity, there would be steps including ① Procurement ② Production ③ Stock ④ Delivery ⓹ Installment ⓺ Maintenance. While with RedteaSIM, all the steps mentioned above will be integrated into a streamlined process to provion SIM Profiles directly into a module or a chipset, so the device will be enabled with cellular connectivity that is flexible and scalable, and normally with LPWAN devices with long life span, SIM profiles update won’t be a problem any more, to scale up business or ship globally in an easy way. All you have to do is to apply for a demo to test you device and decide which module/chipset you wanna apply onto your device, or we may make the decision for you since we’ve tested with the mainstream chipset or modules in the market.
As for the option for the wireless technology, NB-IoT is preferred in terms of power efficiency, wide coverage, long battery life and total BOM cost, and reliability, especially when network speed and bandwidth are not that important.
To accelerate cellular IoT deployment, IoT business stakeholders would encounter so many challenges and opportunities. Traditional SIM tech won’t allow to scale up and on-site service call to SIM switching by human labor can be really expensive. With RedteaSIM, SIM functionality is now integrated directly into the communication chip or modem chip. Devices, module or chipset is now enabled with communication capacity at the production stage , and the complex IoT connectivity procedure, ranging from SIM procurement, production, delivery, stock, installment and maintenance, is now streamlined into a single one stop solution. RedteaSIM is thus bringing benefits for all the stakeholder in Massive IoT value chain, to meet the demands of its typical three features: low cost devices, small data volumes and extreme coverage.
And especially in LPWAN area, when the majority of IoT devices, especially those in smart city, smart environment and other industrial sectors, would prioritize the longevity of several years instead of the same speed and bandwidth of consumer cellular devices, RedteaSIM has dealt with many cases for our customers to follow suit, and proved compatible with mainstream chipset or module maker in an established ecosystems with top players like Deutche Telekom, Qualcomm, Quectel, and MTK.
