Evo nekih informacija o novim Time Capsule & AirPort Extreme:

-Simultaneous Dual-Band 2.4GHz and 5GHz - 450 Mbps

With simultaneous dual-band, you can support both bands together with a single base station. You get simultaneous support for both 2.4GHz and 5GHz. 2.4GHz for your b/g devices like iPhone and iPod touch. 5GHz for your newer 802.11n devices for higher throughput. Macs that support 802.11n will pick the best network

2.4GHz has better range and compatibility with 802.11b/g. 5GHz has better throughput and performance with less interference and is compatible with 802.11a.

‘As I mentioned, Time Capsule is available in two configurations: a 2TB model at $299 and a 3TB model at $499. Both offer incredible value especially when you consider that it includes a full-featured AirPort Extreme Base Station which by itself costs $179.’

When broadcasting 802.11n Wi-Fi in 40Mhz wide mode, the new AirPort Extreme has a maximum output power of 392.64mW, which is more than 2.8 times greater than the 139.32mW maximum output of the previous model.

Ako je ovo istina, može li neko ko se razume u te odnose frekvencije, snage dometa da nam objasni da li ovo znač da će da ‘baci’ signal skoro tri puta dalje. Ako nije toliko, kolika bi bilia optimistična prognoza za daljinu u odnosu na prethodni model?

OK, ne morate da se trudite, kreten ne čta ceo tekst, evo citata:

Theoretically, and in a vacuum, a power increase of 2.8 would provide the same signal strength at 1.6 times the distance, he explained. But real-world usage will vary, and any performance boost could be minimal, perhaps explaining why Apple chose not to advertise the modifications.
