Японские инженеры представили бюджетную систему оптической связи (VLC), устойчивую к засветке в 90 000 люкс.
⚙️ Начинка:
FPGA + Raspberry Pi (связь по SPI)
Спец. кодирование 8B13B (убирает мерцание, держит синхронизацию)
Доступные фотодиоды и фильтры
🚀 Результат: 3,48 Мбит/с на 3 метра.
Главный юзкейс — «умные» светофоры, передающие данные автопилотам без радиопомех.
#LiFi
¿El principio del fin del WiFi? 👀
El LiFi usa luz para enviar datos: más rápido, menos interferencias… pero con límites claros (hola, paredes).
¿Lo ves como complemento del WiFi o como el siguiente gran salto en conectividad? 💡

Световая передача данных: Li-Fi
Картинка: freepik.com Мы привыкли к тому, что технологическое использование света всё больше и больше находит применение в нашей цивилизации: оптические развязки электронных схем, оптические линии связи (в том числе между спутниками), даже прогнозирующийся переход на оптические схемы и оптические процессоры (в относительно недалёком будущем)… Но есть и ещё одна область использования света, которая будет, наверное, не так широко знакома широкой публике, но тем не менее любопытна сама по себе — назовём её условно «оптические линии ближнего радиуса».

🎓 We congratulate Malte Hinrichs from Fraunhofer HHI on his PhD! His dissertation on Physical Layer Design for Pulsed Modulation Optical Wireless Communications advances LiFi systems—boosting range, reducing energy use, and achieving data rates up to 4.25 Gbit/s. With this work, a major step toward efficient, high-performance optical wireless communication has been made. 🚀

Fraunhofer HHI is shaping the future of intelligent & sustainable 5G indoor networks. With convergent architectures (i-RAN), Fiber-to-the-Room & LiFi, AI-based Wi-Fi resource allocation, and secure building automation, our research enables reliable, energy-efficient connectivity. A milestone: the 5G-COMPASS project (2023–2025), funded by BMDV, with 15 partners developing prototypes for open, intelligent ecosystems.

:boost_ok: Does anyone have the full #specifications for IrDA #archived somewhere?
Because I'm looking for a good, short-range protocol that is less complex than #LiFi * for a "digital dead drop".
Most notably because USB dead drops have a shitton of disadvantages as #USB is not designed for that in mind, is extrenmely susceptible to sabotage and vandalism as a #PirateBox *, less complex than #FreedomBox * for #Sneakernet * operations.
Given the IrDA spec is relatively simple on the physical interface, reimplementing it with visible light would allow for more options espechally when it comes to "broadcasting" data to multiple devices when #datacasting like #Toosheh * would be overkill...
@stman @vidak @50htz @theruran @forthy42 as for "protocol" I'd recommend to take a closer look at #IrDA since there are a shitton of cheap transcievers and implementations available and it would allow this to be reused for a secure P2P data exchange and secure contactless networking solution that is inherently harder (if not basically impossible) to eavesdrop on compared to #Bluetooth and #WiFi.
- Plus it'll be a potentially better alternative to #LiFi for #Broadcast useage.
Not to mention I've not seen any IrDA devices >4MBit/s in the wild, with most being 9600bit/s #serial links fir the most part, and having a direct optical data exchange that takes literal seconds instead of minutes would really have a lot of good use cases i.e. in medical fields, where having a fully sterilizeable computer is kibda important and having a docking cradle with a charging coil and optical "port" would really be appreciated.
In fact ITU G.9991 (G.vlc) & IEEE 802.11bb are worth looking into as well just to see advantages and disadvantages...

LiFi (wireless digital networking using LEDs and light sensors has the potential to extend existing cable+WiFi networks as radically as fibre+WiFi extended traditional copper networks. Like WiFi, it has physical limitations, and it will suit some use cases better then others;
