Sigfox Targets Worldwide Coverage with Satellite Launch

Sigfox Satellite

LPWAN technologies such as NB-IoT, Sigfox, and LoRa deliver low power, long range communication at low bitrate and can be used for asset tracking, environmental monitoring, water & electricity meters, and so on. The line-of-sight range between the closest gateway and nodes is usually 10 to 20 km, and coverage can be expanded by connecting several gateways to form a network. However, this is not workable in all locations worldwide, so Sigfox plans to launch a Sigfox satellite in collaboration with Eutelsat in order to provide coverage in places like large deserts such as the Sahara desert, the two poles, as well as oceans as explained by Franck Siegel, chief operating officer at Sigfox. This will for instance enable tracking and monitoring of oil platforms and vessels. The press release does not explains much except Sigfox and Eutelsat will test the first Satellite in H2 2019 before the commercial launch of the “ELO” constellation in 2020.

WeTek Air Android TV 4K HDR Set-Top Box Comes with DVB-T2/C, DVB-S2 or ATSC Tuners

WeTek Air

WeTek was one of the first manufacturers to launch Android set-top boxes with built-in tuners starting with WeTek Play, later followed by WeTek Play 2 model a few years later. In recent years, the company also introduced other Android media devices for the business sector with WeTek Hyperion 4G LTE Android TV TV box, and WeTek Nix with all DRM required for the IPTV market. But it appears WeTek is coming back to the consumer market with their Google certified WeTek Air TV box running Android TV, and equipped with DVB-T2/T/C (Europe), ATSC (US), or DVB-S2 (Worldwide) tuner. WeTek Air hardware specifications are pretty similar to their WeTek Play 2 model, but with various improved features thanks to a new processor: SoC –  Quad core Arm processor (Likely S905D, TBC) System Memory – 2 GB DDR4 Storage – 16 GB eMMC flash + micro SD card slot Video & Audio Output – HDMI 2.0a up to 4K @ 60Hz with …

VideoStrong K1 Plus T2/S2 is an Android 5.1 set-top-box with DVB-S/S2 and DVB-T/T2 tuner that was launched roughly two years ago with Amlogic S905 quad core processor. Since then, the company has now launched variant of the model with Amlogic S912 (e.g. KIII Pro hybrid TV box)  or Amlogic S905D (e.g. KI Pro set-top box) processors. But now, provided the information on Alibaba is correct, the company has launched a new version of KI Plus T2/S2 with Amlogic S805X which should be cheaper, run a more recent Android 7.1 operating system, at the cost of losing support for 4K decoding, since the processor only support Full HD (1080p60) decoding at most. Since the company updated an existing product, some specific details are wrong on Alibaba, but KI Plus T2 S2 (2018) specifications should be as follows: SoC –  Amlogic S805X quad core ARM Cortex-A53 @ up to 1.2 GHz with penta-core Mali-450MP GPU System Memory – 1GB DDR3 Storage – …

Building a Compact Digital TV Transmitter with Raspberry Pi Zero, Pi Camera, and LimeSDR Mini USB SDR Board

There are few affordable standalone systems that allow you to transmit video over the air, and back in 2016, I had the chance to check out V-Bridge Muses-β MPEG-2/-4 encoder and DTV modular taking HDMI or composite video input. It was easy to use and worked fine, but it would still cost close to $600, and might have been a little smaller. Evariste Okcestbon has now created its own digital TV transmitter prototype, combining LimeSDR Mini USB SDR board with Raspberry Pi Zero board, and instead of supporting external input from HDMI or AV ports, he used an official Pi camera for video, and was able to transmit the video over a 1.2 GHz connection to a Raspberry Pi 2 with an RTL-SDR dongle, with the Pi 2 board also taking care of displaying the video signal.   The full flow of transmission can be summarized as follows: Video from Pi Camera AVC2TS software for H.264 encode and transport stream …

Mecool KII Pro Set-Top-Box Upgraded to Amlogic S905D Processor, Android 7.1.2

VideoStrong is making some of the most popular – at least on this website – Android set-box boxes with digital TV tuner on the market with products like Mecool KIII Pro, or KI Pro, mostly because of their affordability. Software may be hit or miss depending on your local requirement (e.g. AC3 on DVB-T2, language encoding issues, etc..), so there’s fairly large number of users and some community tools or firmware such as DVB Channel Editor or Vitmos OS that may make them better devices. Most models are based on Amlogic S905 or S912, but Amlogic launched S905D processor some time ago with better tuner support (multiple demodulator support) which for example allowing me to watch terrestrial TV (DVB-T2) while recording satellite TV (DVB-S2) on Sen5 TV box. VideoStrong decided to upgrade their KII Pro Android set-top box  with S905 processor, DVB-T2/T/C and DVB-S2/S tuners to the new Amlogic S905D processor, and the new version of the device also get …
