| Airport Time Capsule |
Airport Time Capsule
The AirPort Time Capsule (previously known as just Time Capsule), a rectangular tube standing 6.6 inches tall and 3.85 inches wide is a wireless router sold by Apple Inc which is unique among its kind with an internal hard drive featuring network-attached storage (NAS) and a residential gateway router.Unlike some other hard-drive-equipped routers, the Time Capsule uses a SATA interface to the hard drive, versus a USB-to-SATA bridge. Apple, however, declined to disclose the rotational speed of the drive?s platters and if the drive has a SATA 6 Gbps interface or a slower SATA 3 Gbps interface.It comes with a 2 TB or 3 TB single 3.5 inches Seagate Barracuda or a Western Digitals (WD) hard drive inside. |

The AirPort Time Capsule was first released on February 29, 2008, with pricing announced at US$299 (œ199) for the 500 GB version and US$499 (œ329) for the 1 TB version.The first generation Time Capsule included a full AirPort Extreme Base Station with 802.11n wireless, an Ethernet WAN port, three Ethernet LAN ports, and one USB port. The USB port can be used for an external hard drive or a printer to be shared over the network, or both, by using a third-party USB hub.
In early 2009, Apple released the second generation Time Capsule. It offered simultaneous 802.11n dual-band operation, which allows older devices to use slower wireless speeds, without affecting the overall performance of devices that can use higher 802.11n speeds.The second generation model also included the addition of Guest Networking.The hard disk storage space of each model was doubled: capacities were 1 TB 2 TB, while the prices remained unchanged.
In October 2009, several news sites reported that many first generation Time Capsules were failing after 18 months,with some users alleging that this was due to a design failure in the power supplies. Apple confirmed that certain Time Capsules sold between February 2008 and June 2008 do not power on, or may unexpectedly turn off. Apple offered free repair or replacement to affected units.
The third generation Time Capsule was released in October 2009. The only change was a reconfiguration of the internal wireless antenna, resulting in an Apple-reported 50% increase in wireless performance and 25% increase in wireless range when compared to previous models.
The fourth generation Time Capsule, released in June 2011, increased the range of WiFi signals. The internal WiFi card was changed from a Marvell WiFi chip to a better-performing Broadcom BCM4331 chip.Apple again increased the storage space in each model as the hard drive sizes were increased to 2 TB and 3 TB. The 2 TB and 3 TB models were kept at the $299 and $499 price points.Amazon is giving $20 discount on 2 TB model which you could by just for $279.
The fifth generation Time Capsule was released in June 2013 alongside the sixth generation AirPort Extreme. This generation saw the name change to AirPort Time Capsule and to a taller form factor. 802.11ac support was added with this generation. The 2 TB model was kept at $299, but the 3 TB model dropped to $399.

Automatic Wireless Backup and File Sharing
Airport Time Capsule (TC) works smartly with Time Machine in OS X 10.5 Leopard or later to back up your Mac automatically and wirelessly, so you never have to worry about losing anything important again. Every photo. Every file. Every song. Even your apps and OS X settings are saved. AirPort Time Capsule stores it all ? up to 2TB or 3TB of data.Once it is setup on the network, it?s immediately available as a file server and Time Machine backup target. As a Time Machine target, it takes a snapshot of the entire system as an initial backup after which, only the files you?ve changed are backed up ? automatically, wirelessly and in the background. Since Time Machine continuously makes a copy of everything on your Mac ? and saves multiple versions ? you can easily access and restore previous versions of a single file, a folder or even your entire Mac.
As a file server it supports both AFP(Apple Filing Protocol) and SMB(Server Message Block) provides network access to files stored on the built-in hard drive. The 7.6.1 Time Capsule firmware enables remote access of the hard drive with an iCloud account. In the past, users needed a MobileMe account to remotely access data. Fourth generation models are available with 2 TB and 3 TB of built-in storage.
Note:- Time Capsule doesnt support external drives formatted using NTFS (Windows) and doesnt offer the option to format a connected external drive to the HFS+ (Mac) file system for you. In other words, to use an external drive with the Time Capsule, you first need to make sure its already formatted using HFS+ or FAT.
Accessing Files from iPhone and iPad
You can download Apps like Remote File Browser to allow iPhone and iPad access files on Airport Time Capsule . They have both a paid version and a free version. Try the free version first they may fulfill your needs of accessing some movies and songs stored on Airport Time Capsule.
Up to Three Times Faster Wi-Fi
The new Time Capsule is 802.11ac compatible with a dual-band model, capable of operating networks on both the 2.4GHz and the 5GHz frequency bands. It?s equipped with six antennas located on the top of the unit, which Apple claims helps the AirPort users connect from farther distances: three transmit/receive for its 2.4GHz radio, and three transmit/receive for its 5GHz radio.
With three-stream 802.11ac technology, the Airport Time Capsule can reach data rates of up to 1.3Gbps when used with 802.11ac-enabled clients, which is triple the 802.11n standard. 802.11ac Wi-Fi also provides double the channel bandwidth with 80MHz-wide channels providing more room for data to flow faster. If youre using an 802.11a/b/g/n Wi-Fi device, Airport Time Capsule can still optimize the connection for those Wi-Fi standards as well.
Simultaneous Dual-Band Support -Choosing the correct frequency band
No matter which band your wireless devices use, theyll automatically connect to the best available band for the fastest possible performance.
The primary difference between the 2.4 GHz and 5GHz wireless frequencies is range as the 2.4GHz frequency is able to reach farther than the 5GHz frequency.In general, the higher the frequency of a wireless signal, the shorter its range. Thus, 2.4GHz networks cover a substantially larger range than 5GHz wireless networks.When you set up your AirPort Time Capsule, it creates two high-speed Wi-Fi networks:
- A 2.4 gigahertz (GHz) network for 802.11b, 802.11g, and 802.11n devices, such as iPhone,iPod touch, and older computers
- A 5 GHz network for 802.11n, 802.11a, and 802.11ac devices, such as iPhone, iPad, Apple TV,and newer computers
Notes:
When choosing the band for your router, it is also important to consider the capabilities of your wireless clients. Many older laptops, tablets and other typical wireless devices still work only in the 2.4GHz band, while media streaming devices and newer phones have increasingly better adoption in the 5GHz band as well.802.11ac is available only on the 5GHz frequency band.
Beamforming Puts the Focus on Your Device
With 802.11ac technology comes the intelligent, powerful beamforming antenna array. Beamforming is a signal processing technique used in wireless communications, sonars and radars for directional signal transmission and reception. Beamforming is achieved by combining elements in a transmitter/antenna array in a way where signals at particular angles experience constructive interference, while others experience destructive interference. In general, the router knows where an 802.11ac device is on the network. Then AirPort Time Capsule targets its signal to that device. So your Wi?Fi signal is stronger, clearer and faster. And each of its clients exchange information as to their physical locations. They use this information to concentrate their radio energy to achieve the highest possible throughput.
The new Time Capsule offered about the same range as the previous generation, up to about 270 feet away. Its effective range, however, is within approximately 150 feet or less, which is rather standard for a dual-band router. Note that Wi-Fi range varies a great deal depending on the environment. The device also passed my 24-hour stress test, during which it didnt disconnect once.
Internet Access for your Guest
Just like other routers Time Capsule also supports guest networking, you can set up a separate Wi?Fi network just for guests.A guest network allows access only to the Internet, so your primary network - including any external hard drive, printer, or other LAN-attached device - remains secure.
Designed with Performance in Mind- Sped up .Slimmed Down.
Apple has made the new Airport Time Capsule taller and put the antennas at the top, creating a higher platform for dispersing the signal.The new vertical design not only improves Wi?Fi performance, it also saves you valuable desk space. At less than 10 centimetres square, the footprint of AirPort Time Capsule is 75 per cent smaller than its predecessor.
Get Online Safely and Securely
AirPort Time Capsule includes a built-in firewall that creates a barrier between your network and the Internet, protecting your data from malicious attacks. When you set up AirPort Time Capsule, the firewall is automatically turned on
Printer and Hard Drive Sharing
Protect your Hard Drive with a Password
AirPort Time Capsule can turn your external USB hard drive into a secure drive you can share across your Wi-Fi network and access securely over the Internet. All the documents, videos, photos, and other files instantly become available to anyone on the network, Mac and PC users alike. Its perfect
