AirPort Extreme

The first AirPort Extreme was announced at the MacWorld expo in San Francisco on January 7, 2003. It featured 802.11g wireless technology for the first time in an AirPort base station. The name "AirPort Extreme" originally referred to any one of Apple's AirPort products that implemented the (then) newly introduced 802.11g Wi-Fi standard, differentiating it from earlier devices that ran the slower 802.11a and b standards. At that time (circa 2003) the gateway part of this lineup was known as the AirPort Extreme Base Station. With the addition of the even faster Draft-N standards in early 2009 the naming of "Base Station" was dropped, and was renamed to AirPort Extreme. Several minor upgrades followed with the wireless-N models, mostly to change antenna and wireless output power. In 2013, a major upgrade changed the physical structure of the device, added 802.11ac support, and added more antennas. The AirPort Extreme has gone through three distinct physical forms. The earliest models had a similar plastic housing to the original AirPort Base Station, in a round "flying saucer" shape. From 2007 to 2013, the devices took on a flat rounded rectangle shape, similar in layout and size to the Mac mini or early models of the Apple TV. The 2013 model had a more vertical form, taller than it was wide. Discontinuation In 2016, Apple disbanded the wireless router team that developed the AirPort Time Capsule and AirPort Extreme router. In 2018, Apple formally discontinued both products, exiting the router market. Bloomberg noted that "Apple rarely discontinues product categories" and that its decision to leave the business was "a boon for other wireless router makers." ==Features==

Overview • Fully featured 802.11ac Wi-Fi base station • Sleep Proxy Service AirPort Disk The AirPort Disk feature allows users to plug a USB hard drive into the AirPort Extreme for use as a network-attached storage (NAS) device for Mac OS X and Microsoft Windows clients. Users may also connect a USB hub and printer. The performance of USB hard drives attached to an AirPort Extreme is slower than if the drive were connected directly to a computer. This is due to the processor speed on the AirPort Extreme. Depending on the setup and types of reads and writes, performance ranges from 0.5 to 17.5 MB/s for writing and 1.9 to 25.6 MB/s for reading. Performance for the same disk connected directly to a computer would be 6.6 to 31.6 MB/s for writing and 7.1 to 37.2 MB/s for reading. NTFS-formatted drives are not supported. ==Models by generation==

Original generation (2003) The original AirPort Extreme Base Station in 2003 was so named because of its support for the 802.11g standard of the day, as well as for its ability to serve up to 50 Macs or PCs simultaneously. One feature found in most models of this generation was an internal 56K dial-up modem, allowing homes that lacked a broadband connection to enjoy wireless connectivity, albeit at dial-up speeds. It was the only generation to use the "flying saucer" form factor. Later generations would adopt the short, rounded-square form factor that would be seen until 2013. 1st generation On January 9, 2007 the AirPort Extreme began shipping, with support for 802.11n draft specification, and built-in wireless print and storage server. 2nd generation On March 19, 2008, Apple released a firmware update for both models of the AirPort Extreme that, according to third-party reports, allowed AirPort Disks to be used in conjunction with Time Machine, similar to the functionality provided by AirPort Time Capsule. 3rd generation On March 3, 2009, Apple unveiled a new AirPort Extreme with simultaneous dual-band 802.11 Draft-N radios. This allowed full 802.11 Draft-N 2x2 communication in both 802.11 Draft-N bands at the same time. 4th generation On October 20, 2009, Apple unveiled an updated AirPort Extreme with antenna improvements. 5th generation On June 21, 2011, Apple unveiled an updated AirPort Extreme, referred to as AirPort Extreme 802.11n (5th Generation). The detailed table of output power comparison between the 4th generation model MC340LL/A and the 5th generation model MD031LL/A can be seen below: : Note: A 3 dB increase is equivalent to a doubling of power output. 6th generation On June 10, 2013, Apple unveiled an updated AirPort Extreme, referred to as AirPort Extreme 802.11ac (6th Generation). The 6th generation AirPort Extreme (and 5th generation AirPort Time Capsule) featured three-stream 802.11ac Wi-Fi technology with a maximum data rate of 1.3 Gbit/s, which is nearly three times faster than 802.11n. Time Machine was now supported using an external USB hard drive connected to AirPort Extreme (802.11ac model only). ==Comparison chart==

• 802.11n draft-specification support in 1st- to 3rd-generation models. • 802.11ac draft-specification support in 6th-generation model. • All models support IPv6 tunnel mode. • Supported by Apple. ==Discontinuation and support==

According to a Bloomberg report on November 21, 2016, "Apple Inc. has disbanded its division that develops wireless routers, another move to try to sharpen the company’s focus on consumer products that generate the bulk of its revenue, according to people familiar with the matter." Apple announced the discontinuation of its AirPort line, leaving the consumer router market. Apple continued supporting the AirPort Extreme. ==See also==
