The Time Capsule was a combination of a wireless router and a network-attached storage (NAS) device. It offered the standard features of a wireless router, such as Wi-Fi coverage on both 2.4GHz and 5GHz frequency bands, as well as additional features such as Time Machine backup and file sharing. It had three LAN ports and one WAN port, as well as a USB 2.0 port that could be used to connect a printer or an external storage device.

The Time Capsule was easy to set up and manage using the AirPort Utility software application and mobile app provided by Apple. It offered seamless backup for Mac users, with hourly, daily, and weekly backups, and could be used to automatically back up multiple Macs without the need for external hard drives. However, it lacked certain advanced features such as media streaming options and customizable QoS or firewall services.

The Time Capsule went through several generations of upgrades, with the latest model released in 2013 featuring a compact and elegant design, support for 802.11ac Wi-Fi, and improved performance. Despite its limitations, the Time Capsule was a popular choice for Apple fans, especially those with 802.11ac-enabled Macs, due to its ease of use, fast performance, and seamless combination of a wireless router and NAS server.

It features network-attached storage (NAS) and a residential gateway router

The AirPort Time Capsule is a wireless router sold by Apple Inc. that features network-attached storage (NAS) and a residential gateway router. It is essentially a version of the AirPort Extreme with an internal hard drive.

The AirPort Time Capsule was introduced in January 2008 and released in February 2008. The device has been upgraded several times, with the latest model, introduced in 2013, featuring 802.11ac and a 3 TB hard drive. All models include four Gigabit Ethernet ports (3 LAN ports, 1 WAN port) and a single USB port. The USB port can be used for external peripheral devices such as external hard drives or printers.

The NAS functionality utilizes a built-in "server-grade" hard drive. The hard drive typically found in a Time Capsule is the Hitachi Deskstar, which is sold by Hitachi as a consumer-grade product. Apple labelled the drive as a server-grade drive in promotional material for the Time Capsule. Apple states that the Hitachi Deskstar meets or exceeds the 1 million hours mean time between failures (MTBF) recommendation for server-grade hard drives.

The AirPort Time Capsule is designed to work in tandem with the Time Machine backup software utility introduced in Mac OS X 10.5. One of the key features of the Time Capsule is the ability to back up a system and files wirelessly and automatically, eliminating the need to attach an external backup drive.

The AirPort Time Capsule is a more elaborate option in Apple's AirPort family of wireless routers. It is a hard drive-equipped version of the AirPort Extreme that includes 2 TB or 3 TB of storage for backup purposes. The current AirPort Time Capsule looks identical to the AirPort Extreme and is made of all-white, glossy plastic that resembles a milk carton in size and shape.

It was introduced in 2008 and discontinued in 2018

The AirPort Time Capsule was a wireless router sold by Apple Inc. from 2008 to 2018. It was a version of the AirPort Extreme with an internal hard drive. Apple described it as a "Backup Appliance", designed to work with the Time Machine backup software utility.

The Time Capsule was introduced on January 15, 2008, and released on February 29, 2008. The device was upgraded several times, with the latest model introduced in 2013, featuring 802.11ac and a 3 TB hard drive.

In 2016, Apple disbanded its wireless router development team, and in 2018, the company discontinued the entire AirPort line of products, including the Time Capsule. This decision was notable as Apple rarely discontinues product categories.

Over the years, the Time Capsule went through five generations of upgrades and design changes. The first-generation Time Capsule, introduced in 2008, supported 802.11n wireless and came with a 500 GB hard drive. The second-generation model, released in early 2009, offered simultaneous 802.11n dual-band operation and doubled the hard disk storage space to 1 TB and 2 TB.

The third-generation Time Capsule, released in October 2009, featured a reconfigured internal wireless antenna, resulting in improved wireless performance and range. The fourth-generation model, introduced in June 2011, increased the range of Wi-Fi signals and improved the internal Wi-Fi card.

The fifth-generation Time Capsule, released in June 2013, included a fully featured 802.11ac Wi-Fi access point and simultaneous dual-band operation. This generation also saw a name change to AirPort Time Capsule and a redesign with a taller form factor to accommodate the antennas and hard drive.

The device has been upgraded several times, matching upgrades in the Extreme series routers

The AirPort Time Capsule was first introduced on January 15, 2008, and released on February 29, 2008. Since then, the device has been upgraded several times, with each upgrade matching the upgrades in the Extreme series routers.

The earliest versions of the Time Capsule supported 802.11n wireless and came with a 500 GB hard drive in the base model. The latest model, introduced in 2013, features 802.11ac and a 3 TB hard drive. All models include four Gigabit Ethernet ports (3 LAN ports and 1 WAN port) and a single USB port. The USB port can be used for external peripheral devices such as external hard drives or printers.

The second-generation Time Capsule, released in early 2009, offered simultaneous 802.11n dual-band operation, allowing older devices to use slower wireless speeds without affecting the performance of devices that could use higher 802.11n speeds. This generation also included Guest Networking, a feature that allows the creation of a separate wireless network for guests. The hard disk storage space of each model was doubled to 1 TB and 2 TB, while prices remained unchanged.

The third-generation Time Capsule, released in October 2009, featured a reconfiguration of the internal wireless antenna, resulting in a 50% increase in wireless performance and a 25% increase in wireless range compared to previous models.

The fourth-generation Time Capsule, released in June 2011, increased the range of Wi-Fi signals with a Broadcom BCM4331 chip.

The fifth-generation Time Capsule, released in June 2013, included a fully-featured 802.11ac Wi-Fi access point with simultaneous dual-band operation. This generation also saw a name change to AirPort Time Capsule and a redesign with measurements of 3.85 inches square and 6.6 inches high.

The Time Capsule supports the Sleep Proxy Service

The Sleep Proxy Service is an open-source component of zero-configuration networking, designed to assist in reducing power consumption of networked electronic devices. The fifth-generation Time Capsule supports this service.

The Time Capsule is a wireless router sold by Apple Inc. It features network-attached storage (NAS) and a residential gateway router. It is a version of the AirPort Extreme with an internal hard drive.

The Sleep Proxy Service allows a device providing services, such as file sharing, printer sharing, or remote log-in, to sleep, i.e., enter a low-power mode, while its services remain available, even worldwide. This is done by registering with a sleep proxy server on the local network. The sleep proxy server continues to advertise the services on behalf of the sleeping device and listens for incoming connections. When any device attempts to use any proxied service, the proxy server wakes the sleeping device, and the service works as if the sleeping device had remained fully powered.

Any device that can act as a sleep proxy server advertises this on all LANs of which it is a part. A device providing network services, such as file sharing, when its services are not actively being used, can register its services with an available sleep proxy server and sleep until one of its services is needed.

The sleep proxy server continues to advertise the services in Multicast DNS (mDNS) on behalf of the sleeping host. When the sleep proxy server sees an attempt to use any such service, it wakes the sleeping host, and the service proceeds normally.

The Sleep Proxy Service uses the Wake on Demand feature, first offered in Mac OS X Snow Leopard.

The method by which a sleep proxy server wakes a sleeping host is wake-on-LAN. The network interface of a sleeping host with this capability will wake the machine when it receives a specific series of bits, and a packet containing this pattern is a magic packet.

The Sleep Proxy Service is able to advertise any Bonjour-supported services, while the host computer sleeps. Some examples of supported services are:

• File sharing: A host supporting the sleep proxy service, which offers file services, may go to sleep as needed. When someone needs to access shared files, the host will wake up automatically.
• ITunes library sharing: The computer hosting the iTunes library may go to sleep and will automatically wake when someone wishes to browse the iTunes library from a different PC.
• Printer sharing: A printer may be connected and shared from a computer supporting sleep proxy service. The computer can go to sleep when not in use but will wake when needed to service a print job being sent from a different computer.
• SSH: A computer offering SSH access may go to sleep and awaken via the sleep proxy service when an SSH login is initiated.
• Desktop sharing: Similar to the above examples.
