KLUG notes that the new devices are virtually indistinguishable from their older counterparts, but in the detailed tests, they found range and throughput more. At the end of the day, the Airport Extreme Base Station new dramatically improves throughput in the best cases and in a few areas where the signal was previously unusable. In the worst case (place 4), improves the performance to be essentially unusable to totally fine and in the case of the 2010MBP will not be able to connect to all the pushing 23 Mbit/S.
Major improvements with AFS (actual file transfer) to occur outside at the extremes where previously signal was unusable on 2.4 GHz and 5 GHz. really, which tells the story of the (sometimes dramatic) difference that makes the solution WLAN power higher in the 5th generation on the 4th generation.The highest speeds are obtained with the generation of 2011 MacBook Pro, which includes an upgrade "three flow space compliant WLAN stack", which is basically the hardware and software new generation wireless.
The new Airport extreme base station includes a slightly different chipset, moving a come from Marvell a Broadcom: the result of the relocation of Marvell to Broadcom is twofold. First of all, the performance and range is certainly better thanks to transmit more power and improved sensitivity afforded by the new generation chipsets. Second, the combination of lots of Broadcom in material range Apple (from the iPhone, iPad and MacBooks, iMac and Mac Mini) with Broadcom capable access point allows the use of the break-up of the frame or any other technique of packet aggregation which accelerates things in certain scenarios. This is another example of how that with complete hardware control may in fact result in certain advantages - in this case, faster Wi - Fi.
