## Notes from Freifunk meetup `05.02.2025`
* There is a [community day](https://github.com/freifunk-berlin/meta/issues/136) coming up
* The [Ubiquity Rocket](https://www.wlan-shop24.de/b-ware-ubiquiti-rocket-m2-airmax-wlan-accesspoint-wetterfest?srsltid=AfmBOoo-1leNGr4GYyzhaT827qw2UPzgqMLHVDhXy0P-okOppOX6mEEZ6GE) is popular for [directional connections](https://store.ui.com/us/en/products/r5ac-lite)
* [BiQuad antennas](https://martybugs.net/wireless/biquad/) are easy to build successfully, compact, more wide band than yagi antennas. Recommended for beginners. Don't go for [double-biquad](https://buildyourownantenna.blogspot.com/2014/07/double-biquad-sector-antenna-for-2450-mhz-wifi.html), because impedance matching becomes more difficult..
* Upcoming event (open comms) for analogue radio stuff at [xhain](https://x-hain.de/en/calendar/#content) on `07.02.2025`
* Optical links aren't used without fiber, because its difficult to get the light beam to point in the right direction. A project called [koruza](http://www.koruza.net/) achieved an ok throughput, but only a range of 100 meters. The actuators that adjust the direction of the pointer need to be very precise and they need to compensate thermal effects..
* [60 GHz radio](https://store.ui.com/us/en/products/af-60-lr) can be used for long range links that require a high bandwidth
