Canal wifi

Algo que echava de menos en mi iPhone/iPad sin Jailbreak era algún programa tipo auditoría de redes wifi que me permitiera saber en canal emiten los routers. Buscando por la red he encontrado esto en :

TIP: Choosing the best WiFi channel using iPad
As we know, the best way to get strong WiFi signal without any interference, lags, dropouts etc. is choosing the best, most "clean", WiFi channel. There are some Apps that can help us. For Android, PC or Mac...
But Apple closed the ability to scan WiFi networks in iOS. AppStore does not contain any applications that can do that. The only method is a jailbreak. But there is another, official method:

1. Download the AirPort utility via Appstore.
2. Go to iOS settings and find Airport utility
3. Turn WiFi scanner on.
4. Open Airport utility.
5. Tap Scan and again Scan.
6. Wait 10 sec.
7. Now you can see all the networks with their channels and levels.
8. Remember the channels of top 3 networks. Those channels are not for you.
9. Now you can stop scanning.
10. Tap on a "i" button.
11. Now you can see the most busy WiFi channels.
12. Now you know which channels are free or not so busy. Dont forgett about #8.
13. Now you know the best channels for your XAir mixer.

Sencillamente genial. Seguro que más de uno lo encontrará de utilidad.
