Смысл: The main idea is to demonstrate that laser-based wireless communication is a viable, high-performance alternative to traditional radio bridges for long-distance data transmission, offering gigabit speeds and ultra-low latency without requiring radio frequency licenses.
The author successfully deployed a Lantastica TZR laser modem link over 3km, achieving ~950 Mbit/s symmetric throughput with sub-1ms latency.
Смысл: The main idea is that affordable, consumer-grade wireless equipment can be effectively used to create stable network bridges in industrial settings, providing a fast and cheap alternative to expensive cabling for low-bandwidth requirements.
A practical guide on using budget routers and access points to create wireless network bridges for remote industrial buildings and legacy machinery.
Смысл: The main idea is that visible light (VLC) can be used as a high-speed, interference-free alternative to radio-based wireless networks (like WiFi) by utilizing the rapid flickering of LEDs.
Researchers have developed a Visible Light Communication (VLC) system reaching 800 Mbps, potentially turning household LED lamps into radio-free internet access points.
Смысл: The main idea is that by drastically reducing data transmission speed and bandwidth, it is possible to communicate over global distances using very low power (as little as 1 Watt) via the WSPR protocol.
WSPR is a slow-speed digital radio protocol that allows data transmission over thousands of kilometers using minimal power by optimizing for signal sensitivity over speed.
Смысл: The main idea is to evaluate whether the emergence of 4G/LTE wireless internet in 2012 could realistically replace traditional wired broadband based on speed, cost, and convenience.
A 2012 analysis comparing Moscow's wired and wireless internet, suggesting that 4G/LTE could replace wired connections if prices drop and speeds remain stable.
Смысл: The main idea is that mobile internet modems (specifically Yota) can serve as a cost-effective and efficient replacement for expensive corporate wired internet in small offices, provided there is adequate signal coverage.
The author shares a method to drastically reduce office internet expenses by using a single Yota mobile modem to provide connectivity for multiple computers.
