WisCellular Certified Global LTE IoT Arduino Shield Enters Beta Testing

WisCellular

RAK Wireless introduced WisLTE Arduino shield last year based on Quectel BG96 module with support for NB-IoT (Cat NB1), eMTC (Cat M1), and 2G fallback as well as GPS location. WisLTE worked globally, but the company did not go through the certification process, at least not for the global market, meaning the shield could not be used in commercial application. That’s why Rak Wireless has been working on WisCellular shield, also based on Quectel BG96, but this time with global certification. WisCellular specifications: Cellular Module – Quectel BG96 (based on Qualcomm MDM9206) Cellular Network 2G/GSM (GPRS/EPGRS) 4G/LTE-M (Cat M1) NB-IoT (Cat NB1) Global Bands EDGE/EGPRS: 850/900/1800/1900MHz LTE FDD: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B26/B28 LTE TDD: B39 (For Cat M1 Only) Data Rate Cat M1: Max. 300Kbps (DL), Max. 375Kbps (UL) Cat NB1: Max. 32Kbps (DL), Max. 70Kbps (UL) EDGE: Max. 296Kbps (DL), Max. 236.8Kbps (UL) GPRS: Max. 107Kbps (DL), Max. 85.6Kbps (UL) Voice – VoLTE (Cat M1 Only) SMS – Point-to-point MO and MT, …

Samsung Introduces Exynos i S111 NB-IoT Modem + GNSS Chip

Samsung has just announced their first NB-IoT solution with Exynos i S111 chipset with a single chip integrating an NB-IoT capable LTE modem, RF IC, an on-chip security sub-system, and a PUF (Physical Unclonable Function) security solution along with various components such as CPU, and SRAM. The chip apparently also integrates GNSS hardware with support for GPS, Galileo, etc… Exynos i S111 specifications: CPU – Arm Cortex-M7 @ 200MHz On-chip Memory – 512KB SRAM Modem – LTE Release 14 NB-IoT GNSS – GPS, Galileo, GLONASS, BeiDou Interfaces / Peripherals – USI, UART, I2C, GPIO, eSIM I/F, SDIO (Host), QSPI(Single/Dual/Quad IO mode), SMC Security – eFuse, AES, SHA-2, PKA, Secure Storage, Security Sub-System, PUF The chip is also said to features Samsung’s “advanced algorithms for wider coverage”. Many NB-IoT GPS trackers currently implement a two modules solution, so the latest Exynos chip should enable more compact designs. Samsung did not publish numbers about power consumption, apart from the usual 10-year battery …

SIM7020E 4G NB-IoT Mini Development Board Sells for Just $14

Cheap-NB-IoT-Board

We now have plenty to choose from when it comes to NB-IoT development boards or shields, but so far pricing has not been very attractive, and the cheapest NB-IoT solution I found so far was probably Dragino NB-IoT Bee, a XBee compatible board going for $23. But this morning, I saw an even cheaper NB-IoT board with SIM7020E 4G NB-IOT Mini development board selling for $14.30 on Electrodragon. Not quite the price of 2G solutions, but we’re getting there. Board specifications: NB-IoT Module – SIMCom SIM7020E module working globally with B1/B3/B5/B8/B20/B28 bands supported Nano SIM card holder and u.FL connector for NB-IoT Expansion – 9-pin unpopulated 2.54mm pitch header with 2x UART (3.3V / 5V), ADC, Boot, 3.3V, 5V and GND USB – 1x micro USB port that can be recognized by PC, but as Electrodragon puts it: “not sure how to use it”. Misc – Net LED, power key Power Supply – 5V via header (or micro USB port?); …
