====== The Next Steps ======

===== RF Links =====
Once you're connected into AREDN over the internet, the next step is to add an RF link.  For that, a second device can be placed outside and connected back to the hAP via CAT5e.  For this, you can use:
  * A [[https://www.pc-canada.com/item/ROCKETM5.html |Ubiquiti Rocket M5 radio]] with a [[https://www.pc-canada.com/p/go/go.asp?SearchString=ubiquiti+sector+antenna|sector antenna]], or a [[https://www.pc-canada.com/p/go/go.asp?SearchString=ubiquiti+dish|dish antenna]],
  * An integrated [[https://store.mikrotikcanada.ca/search?controller=search&s=LHG+HP%2FXL |MikroTik dish and radio]],
  * A [[https://www.amazon.com/MikroTik-Wireless-Satellite-Antennas-RBLDF-5nD-US/dp/B072LQMD7N/|MikroTik LDF]] with a [[../setups/va7fi/home#july_1_2021|repurposed dish]],
  * ...

===== NPR =====
<QUOTE>
NPR (New Packet Radio) is a custom radio protocol, designed to transport bidirectional IP trafic over 430MHz radio links (ham radio frequencies 420-450MHz). This protocol is optimized for "point to multipoint" topology, with the help of managed-TDMA.  Bitrate is 50 to 500kbps (net, effective bitrate), depending on the RF bandwidth chosen. --[[https://hackaday.io/project/164092-npr-new-packet-radio |Hackaday Project Page]]

See our [[npr |NPR page]] for more details on how to integrate this with AREDN.
