A Day at Chiang Mai Maker Party 4.0

The Chiang Mai Maker Party 4.0 is now taking place until December 9, and I went there today, as I was especially interested in the scheduled NB-IoT talk and workshop to find out what was the status about LPWA in Thailand. But there are many other activities planned, and if you happen to be in Chiang Main in the next few days, you may want to check out the schedule on the event page or Facebook. I’m going to go though what I’ve done today to give you a better idea about the event, or even the maker movement in Thailand. Booth and activity area should be the same over the 4 days, but the talks, open activity, and workshop will be different each day. Today, people could learn how to solder in the activity area. The even was not really big with manufacturers/sellers like ThaiEasyElec, INEX, or Gravitech closer […]

u-Blox Unveils SARA-R4 LTE Cat M1 and SARA-N2 NB-IoT Modules for Professional IoT Applications

While I’ve mostly read about SigFox and LoraWan solutions for long range, low power, and low bitrate communications for the Internet of Things so far, there are many active of planned LPWAN standards for IoT applications, and 3GPP Release 13 standard stipulates two LTE LPWAN standards, namely LTE Cat M1 (eMTC) and LTE Cat NB1 (NB-IoT), with the former  supporting 1 Mbps downlink and uplink peak data rates, and the latter 250 Kbps downlink, and 250 Kbps (multi-tone) or 20 Kbps (single tone) uplink data rates. U-Blox has released modules for both standard with SARA-R4 LTE Cat M1  and SATA-N2 NB-IoT modules. SARA-N2 Cat NB1 cellular module specifications: LPWAN Connectivity – 3GPP Release 13 NB1; NB-IoT bands: 5, 8, 20; downlink: 227 Kbps, uplink: 21 Kbps Positioning – GNSS via Modem Interfaces – 1x UART, 1x SPI, 2x GPIO, 1x DDC(I2C) for GNSS Features – Antenna supervisor, embedded IPv4 & […]
