Sony CXM1501GR ELTRES LPWAN Module Promises a Range of over 100 Km

While there are many LPWAN (Low Power Wide Area Network) standards, three appear to dominate the news namely LoRaWAN, SigFox, and 3GPP NB-IoT/eMTC. They all offer long range and up to 10-year of battery life enabled by the use of low bitrate which is fast enough to send sensor data. We can now add another LWPAN standard to the list, as Sony has developed ELTRES wireless communication standard suitable for IoT networks, and announced their CXM1501GR ELTRES module with a range of over 100km, even while traveling at 100km/h. Key features and specifications: ELTRES Connectivity Antenna radiated power – 20mW Communication direction – Uplink only Frequency – 923.6 MHz to 928.0 MHz (23-channel frequency hopping) Main modulation system – π/2 Shift BPSK Sub-modulation system – Linear chirp modulation Transmission system – Four repeated transmissions of 0.4 sec or shorter packets Reduction of interference with other systems – CSMA (Carrier Sense […]

Xiaomi Mi A2 Review with Android 9.0 Pie

I had been using Xiaomi Mi A1 Android One smartphone since the end of 2017, and was mostly satisfied with it thanks to regular (monthly) firmware update, although I was a bit disappointed by the camera overtime. Eventually I had a serious issue with Mi A1’s eMMC flash, and stopped using it at the end of last year, or roughly after one year of service, since the phone became unusable, unbearably slow. Xiaomi Mi A2 and A2 Lite where released last summer, and having seen Mi A2 was getting an Android 9.0 firmware in Q4 2018, I asked GearBest whether they could send a sample to review the latest Xiaomi Android One phone. They accepted, and I posted the first part of the review in early December. However, at this time, I did not get the update, since it was not released in Thailand, but soon enough Xiaomi Mi A2 […]

Sony Spresense Board Review with NuttX based Spresense SDK

Sony Spresense Arduino compatible board with audio and global navigation satellite systems (GNSS) support and its extension board launched in Japan this summer. The company has now expanded markets, and is offering the boards in the United States and Europe as well. They also tasked an agency to send samples to various reviewers, and I got selected to receive one as well. I’ll start the review by checking out the hardware, shortly discuss software development options, and report my experience with Spresense SDK. Sony Spresense Unboxing I received two packages… … one the main board, and the other for the extension board. The main board package only comes with CXD5602PWBMAIN1 board and an information sheet. The top of the board includes a reset button, four user LEDs, a power LED, a boot recovery button, the camera interface, Sony CXD5247 power management and audio analog interface chip (Black on the photo below, […]
