A peek at FCC filing ...
|We’ve known for a while that the Apple iPad will support 802.11 a/b/g/n. However, thanks to Apple’s FCC filings today, we now know that the device rocks dual-band wireless-N in 2.4 GHz and 5 GHz bands.
This is positive news for future iPad owners. The 2.4 GHz band, which is used by 802.11 b/g/n devices, is currently very crowded, especially if you live in an area that’s densely populated with WiFi hotspots.
The 5 GHz band, on the other hand, is much less crowded than 2.4 GHz, since only 802.11 a and dual-band 802.11 n devices use this band. That means less interference and in many cases higher throughput for devices using the 5 GHz band.
Support for dual-band Wireless-N isn’t a huge surprise since other Apple products like the Airport Extreme already offer dual-band N. However, few portable devices available today support dual-band N, and it’s good to see that Apple went the dual-band route with the iPad.
