The amateur radio community has recognized the benefits of using inexpensive commercial :abbr:`WISP (Wireless Internet Service Provider)` radios to create AREDN |trade| networks. Each of these devices come with the vendor's firmware pre-installed, but by following a few simple steps this firmware can be replaced with an AREDN |trade| firmware image. Several open source software features have been adapted and enhanced to create the AREDN |trade| firmware, including `OpenWRT (Open Wireless Router) <https://en.wikipedia.org/wiki/OpenWRT>`_ and `OLSR (Optimized Link State Routing protocol) <https://en.wikipedia.org/wiki/Optimized_Link_State_Routing_Protocol>`_. The AREDN |trade| team builds specific firmware images tailored to each type or version of radio, and the current list of supported devices is found on the AREDN |trade| website in the `Supported Platform Matrix <https://www.arednmesh.org/content/supported-platform-matrix/>`_.

When selecting a device for your AREDN |trade| hardware there are several things to consider in your decision.
Footnote FCC 9cm sunset ruling (#86) * Footnote FCC 9cm sunset ruling Footnote the 2020 FCC ruling to sunset Amateur operations in the 9cm band. * Footnote FCC 9cm sunset ruling Update 2.4ghz graphic. * Footnote FCC 9cm sunset ruling Update U-NII numbering on graphics. * Footnote FCC 9cm sunset ruling Remove radiofresnel.com.

* Radios should be purchased for the specific frequency band on which they will operate. Currently AREDN |trade| supports devices which operate in several bands. Check the AREDN |trade| `website <https://arednmesh.org>`_ for the latest information.

* Many devices have an integrated dual-polarity :abbr:`MIMO (Multiple Input-Multiple Output)` antenna which helps to leverage multipath propagation. AREDN |trade| has always supported and recommended using MIMO hardware, since these devices typically outperform single chain radios when used as mesh nodes.

* Radios can be purchased separately from the antenna, so it is possible to have more than one antenna option for a radio in order to optimize AREDN |trade| nodes for varying deployment conditions.
update docs for Perl retirement (#146) * update docs for Perl retirement With the retirement of Perl and the inclusion of tunneling in the base build, there are several steps and warnings that no longer apply. These have been removed from the docs. * add tunnel.wanonly description * update slider screenshot

* Costs of devices range from $25 to several hundred dollars for a complete node/antenna system, so there are many options even for the budget-conscious operator.

* Some older or lower cost devices have a limited amount of onboard memory, but firmware images continue to grow in size and functionality. Consider purchasing a device with more memory over one with less memory.

One of the best sources of detailed hardware information is a manufacturer's datasheet, usually available for download from the manufacturer's website. Currently AREDN |trade| supports dozens of device models from manufacturers including GL-iNet, Mikrotik, TP-LINK, and Ubiquiti Networks.

If you are just getting started with AREDN |trade| you can easily begin with one of the low-cost devices that comes with an integrated antenna and a :abbr:`PoE (Power over Ethernet)` unit. If you are expanding your AREDN |trade| network with more sophisticated equipment, you may choose a standalone radio attached to a high-gain antenna.
