The new LTE IoT module from Thundercomm supports Cat-M1, Cat-NB1/NB2, E-GPRS and GNSS
The new Turbo T95 SOM module from Thundercomm is based on the MDM9205 LTE modem from Qualcomm. This modem module is a multi-band multimode solution that supports more than 23 global frequency bands from 450 MHz to 2.1 GHz. Its high reliability, low latency, extended coverage and delay tolerance of Rel.14 LTE NB-2 (NB-IoT) make it a robust, state-of-the-art modem solution. However, the older E-GPRS standard has been integrated to enable radio communications in areas where LTE IoT is not yet available.
LTE low bands: B5, B8, B12, B13, B14, B18, B19, B20, B26, B27, B28, B71, B85
LTE Mid Bands: B1, B25, B2, B66, B3, B4
E-GPRS Bands: B3, B2, B8, B5
Peak Download Speed: 588 kbps (Rel.14 Cat-M1), 127kbps (Rel.14 Cat-NB2)
Peak Upload Speed: 1119 kbps (Rel.14 Cat-M1), 158.5 kbps (Rel.14 Cat-NB2)
With the MDM9205, the T95 module also features the latest generation of Qualcomm GNSS engine (gen9) for GPS, Beidou, GLONASS and Galileo.
The MDM9205 has an integrated Cortex-A7 that can also act as network and application processor. The single core engine is clocked at 800 MHz and has a 256 KB L2 cache. As RTOS operating systems AliOS Things or ThreadX are offered. 32 MB DRAM and 64 MB Flash are also directly integrated in the device, which allows a very small form factor of the module in a 16 x 20 x 2.5mm LGA package. Despite its extremely small size, the module offers an amazing number of interfaces such as UART, SPI, I2C, I2S, PWM, USB2.0, GPIOs and UIM. Especially pleasing is the fact that the T95 can operate in a hosted- and a hostless-mode. With the latter, the application runs directly on the module and therefore requires no external processor and memory resources. In hosted mode, however, the module can be controlled by an external processor like a modem. The user can choose between AT commands (via UART interface) or an API provided in C-code (via a serial interface e.g. SPI).
The temperature range from -40°C to +85°C was designed to make the module usable also in outdoor areas. In addition, the MDM9205 has reduced power dissipation by 70% and chip size by 50% compared to the first-generation MDM9216 modem. The resulting lower price, the particularly small size and the extremely low power dissipation make the T95 the ideal solution for battery-powered IoT products both for indoor and outdoor applications.
