AirPort Extreme (Generation 3, Apple Service part, Early 2009)

According to Apple, this AirPort Extreme (Generation 3) provided “simultaneous dual-band wireless 802.11n networking. When you set up your AirPort Extreme Base Station, it creates two high-speed Wi-Fi networks.”

The AirPort Extreme Generation 3 had 5 ports:

  • 1 10/100/1000Base-T Gigabit Ethernet Wide Area Network (WAN) port (for DSL/cable modem)
  • 3 10/100/1000Base-T Gigabit Ethernet Local Area Network (LAN) (for Ethernet devices, such as printers or computers)
  • 1 USB port (for a USB printer, hard disk, or hub)

This device is packaged as an Apple Service part and does not include the retail packaging. The box, labeled Part Number 661-4908, contains the three parts needed to repair or replace the device including a power adapter, a power plug (North America), and a base station.

This AirPort Extreme model was available for less than 8 months before it was replaced by the Generation 4 model. It measured 6.5 x 6.5 inches square and was 1.3 inches tall. It weighed 1.66 pounds.

AirPort Time Capsule 802.11n (Generation 3, 2TB, 2009)

The AirPort Time Capsule was a device that combined Apple’s Wi-Fi base station with a built-in hard drive that allowed network-attached storage (NAS). This example (A1355) is the third of five generations of this product released between 2008 and 2013. Apple described this product as a “Backup Appliance” that was designed to work with its Time Machine software that was released with Mac OS X 10.5.

Using the Time Machine software, Time Capsule creates backups of the operating system and files wirelessly and automatically, thus eliminating the need for an external hard drive. Time Machine made hourly backups of the files that were changed and managed older backup images to save space. The initial backup of a computer using Time Machine could take several hours (or overnight) on an 802.11n wireless network, but subsequent hourly backups occurred instantly and far more quickly (depending on file sizes).

This Generation 3 model used the same design as Generations 1–4: 7.7 inches square and 1.4 inches tall. The Generation 3 included the following interfaces:

  • One Gigabit Ethernet WAN port for connecting a DSL or cable modem
  • Three Gigabit Ethernet LAN ports for connecting computers or network devices
  • USB port for connecting a USB printer or USB external hard drive
  • 802.11n wireless

Time Capsule used a Hitachi Deskstar hard drive, the same hard drive sold with Apple’s Xserve server products. The Hitachi Deskstar met or exceeded 1 million hours mean time between failures (MTBF) status, common for server-grade hard drives.

AirPort Extreme Base Station (Generation 4, 2009)

The AirPort Extreme was a wireless base station that combined the functions of a router, network switch, wireless access point, Network-Attached Storage (NAS), and other features.

The AirPort Extreme Base Station Generation 4 (model A1354) was released in 2009 with a white, rounded-rectangle design that was similar to the look of the first-generation Mac mini and original Apple TV. AirPort Extreme Base Station Generations 1–5 shared the same design until a tower-like design was used for the final Generation 6 model.

The AirPort Extreme Base Station measured 6.5 inches square, 1.3 inches tall, and weighed 1.66 pounds. It supported 802.11a/b/g/n wireless network protocols.

The AirPort Extreme Base Station Generation 4 had the follwing interfaces:

  • One Gigabit Ethernet WAN port for connecting a DSL or cable modem
  • Three Gigabit Ethernet LAN ports for connecting computers or network devices
  • USB 2.0 port for connecting a USB printer or USB external hard drive
  • 802.11n wireless

AirPort Express 802.11n (Generation 2, 2012)

The AirPort Express Generation 2 functioned as a wireless access point, to extend the range of a network, as an Ethernet-to-wireless bridge, as a print server, and/or as an audio server. This model allowed up to 50 networked users using the 802.11a/n Wi-Fi standard.

Connectors included an audio connector that combined a 3.5 mm minijack socket and a mini-TOSLINK optical digital connection. On August 28, 2018, AirPlay 2 support was added to the Generation 2 AirPort Express, giving it features similar to HomePod.
