Ever since Ap­ple in­tro­duced Air­Port in 1999, it has been at the fore­front of wire­less tech­nol­ogy, mak­ing it easy to shut­tle files back and for­wards be­tween all your de­vices ca­ble-free. It’s hard to imag­ine us­ing a Mac, iPhone, iPad or iPod touch with­out it.

Wire­less tech­nol­ogy hasn’t stood still in the years since then. The orig­i­nal Air­Port brought us the IEEE 802.11b net­work­ing stan­dard with a the­o­ret­i­cal max­i­mum band­width of 11Mbps, and since then we’ve had 802.11g (54Mbps), 802.11n (600Mbps), and now 802.11ac (1.3Gbps), found in all new Mac and iOS de­vices.

802.11ac brings more than just a huge boost to trans­mis­sion rates. It’s also more ro­bust over longer dis­tances and when pass­ing through walls and other ob­sta­cles, so you’re less likely to ex­pe­ri­ence dead zones around your home.

Most wire­less de­vices uses dif­fer­ent parts of the ra­dio spec­trum, typ­i­cally ei­ther 2.4GHz or 5GHz. 2.4GHz is the most com­mon and crowded in terms of Wi-Fi traf­fic, while 5GHz is still rel­a­tively un­used. The good news is that 802.11ac routers such as the lat­est Air­Port Ex­treme can si­mul­ta­ne­ously broad­cast in both bands, with the 2.4GHz one of­fer­ing a slower yet more com­pat­i­ble con­nec­tion for your older hard­ware to use, mak­ing it easy all of your de­vices to get on­line.

The other good news is that while there are other Wi-Fi stan­dards on the hori­zon, in­clud­ing 802.11ax with up to 10Gbps trans­fers, 802.11ac is still rel­a­tively new, so your Mac, iOS de­vices and Air­Port Ex­treme or Time Cap­sule equipped with it should last you a good few years yet.
