Antenna Power: Airport Extreme's Six-Antenna System Explored

Apple's Airport Extreme is a line of residential gateways that combine the functions of a router, network switch, wireless access point, NAS, and other features. The number of antennas in the Airport Extreme varies depending on the generation of the device. The 5th Generation Airport Extreme, for example, has three antennas, while the 6th Generation model features six antennas. The number of antennas impacts the range and signal strength of the device, with a higher number of antennas generally resulting in improved performance. Apple discontinued the development of its wireless router lineup, including the Airport Extreme, in 2016, but limited hardware and software support continued until 2023.

The Airport Extreme has 6 built-in antennas

The Airport Extreme is a line of residential gateways by Apple Inc. that combines the functions of a router, network switch, wireless access point, NAS and other functions. 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.

The Airport Extreme was first announced at the MacWorld Expo in San Francisco on January 7, 2003. It featured 802.11g wireless technology, which was the first time this had been included in an Airport Base Station. The name "Airport Extreme" originally referred to any of Apple's Airport products that implemented the 802.11g Wi-Fi standard. This differentiated these products from earlier devices that ran the slower 802.11a and b standards.

In 2009, the naming of the "Base Station" was dropped, and the product was renamed to simply "Airport Extreme". Several minor upgrades followed, mostly changing the antennas and wireless output power. In 2013, a major upgrade changed the physical structure of the device, added 802.11ac support, and added more antennas. This upgrade also nearly tripled the maximum data rate of the previous model, bringing it to 1.3 Gbit/s.

The Airport Express has 2 built-in antennas

The placement of the antennas is also important. Antennas that are placed better can result in improved signal strength and range. Additionally, the frequency of the router can affect its range. For example, a 5GHz frequency typically has a shorter range than a 2.5GHz frequency.

The 802.11 protocols are not directly related to the number of antennas. Instead, they are related to the frequency of the router. For instance, the 802.11n protocol uses a 2.4GHz frequency, while the 802.11ac protocol uses a 5GHz frequency.

It's worth noting that having more antennas doesn't always guarantee better performance. Other factors, such as transmit power, antenna gain, and the surrounding environment, can also influence the range and signal strength of a router.

In conclusion, while the Airport Express has fewer antennas than the Airport Extreme, it may still provide sufficient range and signal strength for your needs, especially if you don't require the latest "ac" protocol.

The Airport Extreme's antennas are placed better than the Airport Express's

The Airport Extreme is a line of residential gateways by Apple Inc. that combines the functions of a router, network switch, wireless access point, NAS, and other functions. The Airport Express, on the other hand, is a device that allows users to extend their WiFi network.

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.

The Airport Express, however, has two built-in antennas, while the Airport Extreme has six built-in antennas. This gives the Airport Extreme a better range and signal strength. In addition, the Airport Extreme has a much more even gain configuration between its three antennas.

The Airport Extreme also has better output power. The Airport Express has a maximum output power of 26dbm, while the Airport Extreme has an output power of 32.5dbm. This gives the Airport Extreme a much greater range, allowing it to cover larger areas with a strong signal.

In terms of placement, the Airport Extreme's antennas are strategically placed to maximize range and signal strength. The Airport Express, on the other hand, has antennas that are placed in a way that may not optimize their performance.

Overall, the Airport Extreme's antennas are placed better than those of the Airport Express. The Airport Extreme has more antennas, better output power, and a more strategic placement of antennas, resulting in superior range and signal strength.

The Airport Extreme's antennas have a higher gain than the Airport Express's

The Airport Extreme is a line of residential gateways by Apple Inc. that combines the functions of a router, network switch, wireless access point, and NAS. 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.

The Airport Extreme has a higher number of antennas compared to the Airport Express, with six built-in antennas compared to the Airport Express's two. This gives the Airport Extreme a better range and signal strength. The higher number of antennas allows the Airport Extreme to transmit and receive data using multiple wireless antennas in tandem, increasing both the range and throughput of the wireless network.

The Airport Extreme also has a higher output power compared to the Airport Express. The Airport Extreme has a 32.5 dBm output power, while the Airport Express has a lower output power of 26 dBm on 5.8 and 22 dBm on 2.4. This higher output power contributes to the improved range and signal strength of the Airport Extreme.

In addition to the higher number of antennas and output power, the Airport Extreme also has a more even gain configuration between its antennas. This means that the Airport Extreme can provide more consistent performance across different areas, reducing the likelihood of disconnects and providing a more stable connection.

The combination of a higher number of antennas, increased output power, and a more even gain configuration results in the Airport Extreme having a higher gain and improved performance compared to the Airport Express. This makes the Airport Extreme a more suitable option for larger areas or environments with a significant number of electronic devices that may cause interference.

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.

The Airport Extreme antennas are internal. The 5th Generation Airport Extreme has 6 built-in antennas. The Airport Extreme (802.11n) does not have an external antenna port, whereas the Airport Extreme Base Station (802.11b/g) does. The Base Station model has a round "flying saucer" form factor and a jack for an external antenna on the back. The Airport Extreme (802.11n) model has a flat rounded rectangle shape and does not have a port for an external antenna.

The Airport Extreme (802.11n) model has multiple internal antennas. The internal antennas of the Airport Extreme provide better range and signal strength compared to the Airport Express, which has 2 built-in antennas. The Airport Extreme's internal antennas are placed better and are more advanced, allowing it to have a better range. The number of antennas is not the only factor that determines the range of a router. The transmit power of the router's Wi-Fi card and the antennas also play a significant role in determining the range.

The Airport Extreme has a much more even gain configuration between its internal antennas. The performance of the Airport Extreme is relatively comparable to the Time Capsule, which has lower gain on its internal antennas. The internal antennas of the Airport Extreme provide a more stable connection with fewer disconnects compared to other routers.
