Overview AirPort debuted on July 21 1999 at the Macworld Expo in New York City with Steve Jobs picking up an iBook supposedly to give the cameraman a better shot as he surfed the Web The applause quickly built as people realized there were no wires The initial offering included an optional expansion card for Apple s new line of iBook notebooks plus an AirPort Base Station The AirPort card a repackaged Lucent ORiNOCO Gold Card PC Card adapter was later added as an option for almost all of Apple s product line including PowerBooks eMacs iMacs and Power Macs Only Xserves do not have it as a standard or optional feature The original AirPort system allowed transfer rates up to 11 Mbit s and was commonly used to share Internet access and files between multiple computers On January 7 2003 Apple introduced AirPort Extreme based on the 802 11g specification AirPort Extreme allows theoretical peak data transfer rates of up to 54 Mbit s and is fully backward compatible with existing 802 11b wireless network cards and base stations Several of Apple s desktop computers and portable computers including the MacBook Pro MacBook Mac Mini and iMac shipped with an AirPort Extreme 802 11g card as standard All other modern Macs have an expansion slot for the card AirPort and AirPort Extreme cards are not physically compatible AirPort Extreme cards cannot be installed in older Macs and AirPort cards cannot be installed in newer Macs The original AirPort card was discontinued in June 2004 On June 7 2004 Apple released the AirPort Express base station as a Swiss Army knife product It can be used as a portable travel router using the same AC connectors as on Apple s AC adapters as an audio streaming device with both line level and optical audio outputs and as a USB printer sharing device through its USB host port On January 9 2007 Apple unveiled a new AirPort Extreme 802 11 Draft N Base Station which introduced 802 11 Draft N to the Apple AirPort product line This implementation of 802 11 Draft N can operate in both the 2 4GHz and 5GHz ISM bands and has modes that make it compatible with 802 11b g and 802 11b a The number of Ethernet ports was increased to fourne nominally for WAN three for LAN but all can be used in bridged mode A USB port was included for printers and other USB devices The Ethernet ports were later updated to Gigabit Ethernet on all ports The styling is similar to that of the Mac Mini and Apple TV On January 15 2008 Apple introduced Time Capsule an AirPort Extreme 802 11 Draft N with an internal hard drive The device includes software to allow any computer running a reasonably recent version of Mac OS or Windows to access the disk as a shared volume Macs running Mac OS X 10 5 and later which includes the Time Machine feature can use the Time Capsule as a wireless backup device allowing automatic untethered backups of the client computer As an access point the unit is otherwise equivalent to an AirPort Extreme 802 11 Draft N with four Gigabit Ethernet ports and a USB port for printer and disk sharing On March 17 2008 Apple released an updated AirPort Express Base Station with 802 11 Draft N 2x2 radio All other features analog and digital optical audio out single Ethernet port USB port for printer sharing remained the same At the time it was the least expensive 99 device to handle both frequency bands 2 4GHz and 5GHz in 2x2 802 11 Draft N On March 3 2009 Apple unveiled AirPort Extreme and Time Capsule products with simultaneous dual band 802 11 Draft N radios This allows full 802 11 Draft N 2x2 communication in both 802 11 Draft N bands at the same time On October 20 2009 Apple unveiled the updated AirPort Extreme and Time Capsule products with antenna improvements the 5 8Ghz model resulting in wireless performance gains of both speed and range also stated is a resulting performance improvement time reduction on Time Capsule backups of up to 60 All current AirPort base stations and cards work with third party base stations and wireless cards that conform to the 802 11a 802 11b 802 11g or 802 11 Draft N networking standards It is not uncommon to see wireless networks composed of several types of AirPort base station serving old and new Macintosh Microsoft Windows and Linux systems Apple s software drivers for AirPort Extreme also support some Broadcom and Atheros based PCI Wireless adapters when fitted to Power Mac computers Due to the nature of Draft N hardware there is no assurance that the new model will work with 802 11 Draft N routers and access devices from other manufacturers Base stations An AirPort base station is used to connect AirPort enabled computers to the Internet each other a wired LAN and or other devices AirPort Original Graphite AirPort Base Station The original AirPort known as Graphite features a modem and an Ethernet port It employs a Lucent WaveLAN Silver PC Card as the Radio and uses an embedded AMD Elan processor It was released July 21 1999 The Graphite AirPort Base Station is functionally identical to the Lucent RG 1000 wireless base station and can run the same firmware Due to the original firmware locked limitations of the Silver card the unit can only accept 40 bit WEP encryption Later aftermarket tweaks can enable 128 bit WEP on the Silver card Aftermarket Linux firmware has been developed for these units to extend their useful service life A second generation model known as Dual Ethernet or Snow was introduced on November 13 2001 It features a second Ethernet port when compared to the Graphite design allowing for a shared Internet connection with both wired and wireless clients Also new was the ability to connect to America Online s dial up service feature unique to Apple base stations This model is based on Motorola s PowerPC 855 processor and contained a fully functional original Airport Card which can be removed and used in any compatible Macintosh computer AirPort Extreme Base Station AirPort Extreme Base Station The AirPort Base Station was discontinued after the updated AirPort Extreme was announced on January 7 2003 In addition to providing wireless connection speeds of up to a maximum of 54 Mbit s it adds an external antenna port and a USB port The antenna port allows the addition of a signal boosting antenna and the USB port allows the sharing of a USB printer A connected printer is made available via Bonjour s zero configuration technology and IPP to all wired and wireless clients on the network A second model M8930LL A lacking the modem and external antenna port was briefly made available but then discontinued after the launch of AirPort Express see below On April 19 2004 a third version marketed as the AirPort Extreme Base Station with Power over Ethernet and UL 2043 was introduced that supports Power over Ethernet and complies to the UL 2043 specifications for safe usage in air handling spaces such as above suspended ceilings All three models support the Wireless Distribution System WDS standard The model introduced in January 2007 does not have a corresponding PoE UL compliant variant An AirPort Extreme base station can serve up to 50 wireless clients at once and thus is more suitable for a corporate environment than the AirPort Express AirPort Extreme Base Station The AirPort Extreme was updated on January 9 2007 to support the 802 11a b g and Draft N protocols This revision also adds two LAN ports for a total of three It now more closely resembles the square shaped Apple TV and Mac Mini and is about the same size and half the height of the Mini The new 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 clients Users may also connect a USB hub and printer The AirPort Extreme has no port for an external antenna On August 7 2007 the AirPort Extreme began shipping with Gigabit Ethernet matching most other Apple products On March 19 2008 Apple released a firmware update for both models of the AirPort Extreme to allow AirPort Disks to be used in conjunction with Time Machine similar to the functionality provided by Time Capsule On March 3 2009 Apple unveiled a new AirPort Extreme with simultaneous dual band 802 11 Draft N radios This allows full 802 11 Draft N 2x2 communication in both 802 11 Draft N bands at the same time On October 20 2009 Apple unveiled the updated AirPort Extreme Base Station with antenna improvements resulting in wireless performance gains of both speed and range Also stated is a resulting performance improvement time reduction on Time Machine backups of up to 60 AirPort Extreme Model Wi Fi Standard Comments M9470LL A A1084 802 11b g MB321LL A A1264 802 11b g n AirPort Express AirPort Express base station The AirPort Express is a simplified and compact AirPort Extreme base station It allows up to 10 networked users and includes a feature called AirTunes The original version M9470LL A model A1084 was introduced by Apple on June 7 2004 and includes an analogptical audio mini jack output a USB port for remote printing or charging the iPod and a single Ethernet port The main processor in the AirPort Express 802 11g version is a Broadcom BCM4712KFB wireless networking chipset This has a 200 MHz MIPS processor built in The audio is handled by a Texas Instruments Burr Brown PCM2705 16 bit digital to analog converter The device can be used as an Ethernet to wireless bridge under certain wireless configurations An updated version MB321LL A model A1264 featuring the faster 802 11 Draft N draft specification and operation in either of the 2 4GHz and 5 GHz bands was released on March 17 2008 with almost all other features identical The revised unit includes an 802 11a n 5 GHz mode which allows adding Draft N to an existing 802 11b g network without disrupting existing connections while preserving the increased throughput that Draft N can provide Up to 10 wireless units can connect to this AirPort Express Both versions allow you to extend the range of a network or to join as a dedicated printer and audio server An often overlooked feature of the AirPort Express is that its 3 5mm stereo mini jack connection also functions as a TOSLINK optical digital connector when used with an appropriate adaptor allowing connection to an external DAC or amplifier with internal DAC This allows CDs ripped in iTunes in Apple Lossless format to stream to the AirPort Express which will in turn output a bitstream which is bit for bit identical to the original CD provided volume adjustments Sound Check and Sound Enhancer are switched off for playback in iTunes DTS encoded CDs ripped to Apple Lossless audio files which decode as digital noise in iTunes will play back correctly when the AirPort Express is connected via TOSLINK to a DTS compatible amplifierecoder AirPort Express Model Wi Fi Standard Wireless to Ethernet Bridge mode M9470LL A A1084 802 11b g No MB321LL A A1264

an AirPort Express or Apple TV The AirPort Express s streaming media capabilities use Apple s Remote Audio Output Protocol RAOP a proprietary variant of RTSP RTP Using WDS bridging the AirPort Express can allow AirTunes functionality as well as Internet access file and print sharing etc across a larger distance in a mixed environment of wired and up to ten wireless clients AirTunes can be controlled by a Keyspan USB enabled infrared remote control plugged into the USB port but the Apple Remote s volume buttons cannot control AirTunes However volume control can be adjusted using the slider within iTunes AirTunes will not stream a video s audio iTunes Remote a free application available for the iPhone and iPod Touch provides a remote control of AirTunes and Apple TV over the Wi Fi network and the ability to search for songs in iTunes and select them for play Speakers attached to an AirPort Express can be selected from within the program allowing full AirTunes compatibility Several third party AirPort Express clients can connect an AirPort Express to sources other than iTunes including Rogue Amoeba s Airfoil for Mac OS X and Windows axStream former oAEP for Windows

server Time Capsule can serve to back up multiple Macs It also includes all AirPort Extreme 802 11 Draft N functionality On March 3 2009 the Time Capsule was updated with simultaneous dual band 802 11 Draft N capability remote AirPort Disk accessibility through Back to My Mac and the ability to broadcast a guest network at the same time as an existing network On October 20 2009 Apple unveiled the updated Time Capsule with antenna improvements resulting in wireless performance gains of both speed and range Also stated is a resulting performance improvement time reduction on Time Capsule backups of up to 60 Time Capsules have demonstrated to have a ventilation and cooling flaw in their design resulting in a high failure rate after about 18 months of use citation needed AirPort Cards An
