 +====== MediaTek / Ralink ======
 +===== General =====
 +  * On May, 5th 2011, MediaTek bought Ralink.
 +  * Most WNICs are supported by the ''​rt2x00''​ driver family. See [[doc:​howto:​wireless.overview]]
 +  * Websites with more background information ​
 +    * [[wp>​Ralink]]
 +    * http://​www.mediatek.com
 +    * http://​wikidevi.com/​wiki/​Ralink
 +    * http://​wikidevi.com/​wiki/​MediaTek
 +
 +===== Ralink ramips =====
 +  * A quite good source for product briefs on MediaTek/​Ralink SoCs in pdf-form seems to be here: http://​wikidevi.com/​files/​Ralink/​.
 +  * OpenWrt specific:
 +    * all MediaTek/​Ralink SoCs are merged under the target **''​ramips''​**.
 +    * building a target requires a target-specific firmware (that is, most devices need customized firmware). The kernel is patched with the command line that has the board name in it. This mechanism is similar to what is done for [[doc/​hardware/​soc/​soc.qualcomm.ar71xx|ar71xx]] platforms.
 +    * browse the source code: https://​dev.openwrt.org/​browser#​trunk/​target/​linux/​ramips
 +  * FIXME: there might still be some historical information in the OpenWrt dev wiki https://​dev.openwrt.org/​wiki/​platforms,​ but it must be well hidden then. Seems there is nothing that can be found today...

 +  * MT7620 vs. RT5350
 +    * both chips are very similar on the software layer.
 +    * MT7620 is the successor, it's "​faster and better",​

 +    * RT5350 is still available and cheaper, http://​cdn.sparkfun.com/​datasheets/​Wireless/​WiFi/​RT5350.pdf
 +    * see here for a comparisson:​ http://​vonger.cn/?​p=242
 +  * MT7621
