Interesting. I&#x27;ve been watching various Wi-Fi HaLow modules for a couple years now. They are interesting alternatives to LoRa and Zigbee which seem to have low data rates (from a quick Google Search) of best casees 50kbit&#x2F;s and 250kbit&#x2F;s respectively vs. Halow&#x27;s best case 15Mbit&#x2F;s. Obviously, this all depends on a lot of factors (coding scheme, range, noise, etc.).<p>It&#x27;s unfortunate that the modules cost so much (single unit costs):<p>Alfa Network ($20): <a href="https:&#x2F;&#x2F;asiarf.com&#x2F;product&#x2F;wi-fi-halow-sub-ghz-wireless-module-2-mm6108-mm610x-001&#x2F;" rel="nofollow">https:&#x2F;&#x2F;asiarf.com&#x2F;product&#x2F;wi-fi-halow-sub-ghz-wireless-modu...</a><p>Morse Micro ($30): <a href="https:&#x2F;&#x2F;www.mouser.com&#x2F;c&#x2F;?marcom=191003943" rel="nofollow">https:&#x2F;&#x2F;www.mouser.com&#x2F;c&#x2F;?marcom=191003943</a><p>Silex ($33): <a href="https:&#x2F;&#x2F;www.mouser.com&#x2F;c&#x2F;?marcom=191003943" rel="nofollow">https:&#x2F;&#x2F;www.mouser.com&#x2F;c&#x2F;?marcom=191003943</a><p>As with all these types of unpopular modules, the SDKs and software documentation are not that freely available, except for these $70 SparkFun Pi HATs: <a href="https:&#x2F;&#x2F;www.sparkfun.com&#x2F;products&#x2F;19956" rel="nofollow">https:&#x2F;&#x2F;www.sparkfun.com&#x2F;products&#x2F;19956</a><p>Those all have FCC certs, but if you get modules from China, without certifications, it can be a lot cheaper ($5): <a href="https:&#x2F;&#x2F;www.alibaba.com&#x2F;product-detail&#x2F;New-Generation-900MHz-WiFi-802-11ah_1600545719884.html?spm=a2700.7724857.0.0.1d632443rJcKmb" rel="nofollow">https:&#x2F;&#x2F;www.alibaba.com&#x2F;product-detail&#x2F;New-Generation-900MHz...</a> But who knows how they actually perform or what documentation they actually have.<p>I would enjoy making a long-range Wi-Fi camera with these (assuming you can buy a base station Wi-Fi adapter for your computer, with drivers). If this random Google Image is anything to go by, <a href="https:&#x2F;&#x2F;www.macxdvd.com&#x2F;mac-dvd-video-converter-how-to&#x2F;article-image&#x2F;h.265-vs-h.264-bitrate.png" rel="nofollow">https:&#x2F;&#x2F;www.macxdvd.com&#x2F;mac-dvd-video-converter-how-to&#x2F;artic...</a>, depending on if you encode video into H264 or H265, you might be able to fit a 60fps 1080p into a stream at a decent range.

So what is so ground breaking around this WiFi connection? We have done WiFi links that spans 20+ km for years using off the shelf ubiquiti and mikrotik equipment. Are they saying they can do the 9.9 miles without directional antennas, just blasting the signal using a unidirectional antenna?
