4T4R WIFI, the 4 WIFI antennas to achieve more speed
Surely you have wondered why the most modern and fast USB WIFI adapters carry 4 external antennas, and if this really increases the speed and the features of the WIFI adapter. Actually yes, it is necessary to carry 4 antennas, to overcome the speeds of 1200 Mbps of WiFi transmission.
4T4R is the default configuration for 5G type experiences in the WIFI environment that is currently used. The potential speed and coverage capabilities of 5G mobile that will come in the future is anticipated by the WIFI 4T4R system that we present in this article.
The most advanced WIFI AC technology takes a 4T4R configuration to allow high wireless power with four external antennas. The main characteristics of this 4T4R equipment is its simultaneous dual band Wi-Fi AC high performance, compatible with all 802.11a / b / g / n / ac standards. The four antennas are to create 4 channels of data transmission and have up to 600Mbps in the 2.4GHz band,
The 4T4R Dual Band WIFI antennas work with four dual external antennas that have a total of 8 radios and 16 wireless amplifiers of which four emitters are high gain. By emitting and receiving simultaneously in the 2.4GHz and 5GHz frequencies to achieve a speed of up to 600Mbps in the 2.4GHz band with Wi-Fi N and up to 1300Mbps in the 5GHz band.
The new Gigabit dual band routers also have Wi-Fi AC MIMO 4T4R wireless standard that transmit at speeds above 1200Mbps but we will only get the maximum performance if we have MIMO 4T4R clients,
MIMO “Multiple Input Multiple Output” is used to allow more WiFi speed using several antennas simultaneously, MIMO technology is achieved with less data loss, less retransmissions are needed and the speed increases. Thanks to this configuration, the wireless signal can reach us by several routes (direct or bouncing against walls for example) and we can use it to increase performance.
This technological wonder of 4 antennas transmitting at the same time only we can enjoy it if we have an access point AP WIFI transmitter, that is to say a router emitting with 4T4R AC technology and on the other side, that is to say as a WIFI client a receiver also 4T4R like this :
WIFI devices with MIMO 4T4R technology:
1. Router AC1900 4T4R.
2. WIFI Client AC1900 4T4R.
The best advice when we have to decide which router WIFI AC you want to consider the peculiarities of WiFi AC is that it works with a double band. On the one hand, the 2.4 GHz band, which is the most common and used by the vast majority of routers, and on the other hand the 5 GHz band, which is less crowded and which, in turn, offers higher performance , allowing the multiplayer game, streaming video in Full HD and 4K in several home devices, going through P2P downloads on several computers at once. In general the WIFI AC system is imprescidible for an intensive use of the internet connection.
It is important to know that the maximum speeds are announced by adding the two bands, so if we only use one band, such as 2.4Ghz, we will get 600 Mbps maximum even if the router is 1900AC. But even so the 2.4Ghz band still has advantages because it is slower, but has greater coverage and range in distance, while the 5GHz band is much faster but does not go that far. To learn more about the advantages of WIFI AC see this article.
Therefore, it is a good idea to use 5Ghz for devices that are going to be connected near the router and need a lot of speed and use the 2.4 GHz frequency for farther devices or take the internet to other nearby buildings with WIFI repeater systems like the famous one pack Long range antenna and repeater router OpenWrt SILICEO. This long range pack can receive WIFI up to 1000 meters d edistancia and repeat it with a router of 2.4ghz for the whole house, they are only 150 Mbps but enough for that range.

1. Router AC1200 4T4R. WIFI router with 4 Gigabit ports ALFA NETWORK AC1200R
A Gigabit router with WiFi AC and the technological wonder that every Gamer or online worker wants to have nearby. Only with changing the router will we significantly improve the performance of a network in our home or office. Finally, in 2021, fiber optic offers ultra-fast internet connection speeds, but what does it do if the routers installed by internet operators become obsolete? But Alfa Network has thought about this and offers us solutions both on the side of the router or access points and on the side of the WIFI client.
The new ALFA NETWORK AC1200R router Includes four gigabyte LAN ports to connect wired products such as smart-tv, video game consoles or computer with cable, PC or other network devices at incredibly fast wired connection speeds thanks to its four 5dbi antennas. The 4 antennas transmitting and receiving signal in 802.11ac at maximum speed up to 1200Mbps.
The AC1200 e sun WIFI Giga-Fast Wi-Fi router that provides support for the latest wireless standards (802.11 2.4 GHz dual band ac + 5 GHz) for the fastest speeds. All Ethernet LAN ports (4 ports + 1 WAN port) are Gigabit ports. It also has two USB 2.0 connectors to share files on the network by connecting an external storage.

With the Alfa AC1200R router, we will have installed 5 Gigabit ports (4 x LAN and 1 X WAN) + 2 USB 2.0 ports for SAMBA and share the external USB storage in addition to the characteristics of the Alfa Network router as a complete firewall. Site blocking, Wifi Planning schedules, Transmission power adjustment, QoS, IPv4 & amp; IPv6, WPS, Repeater … Frequency – 2.4GHz / 5GHz and power – 12V 2 A
A great advantage of this router with WiFi AC is that it has several Gigabit ports. The ports compatible with the Gigabit Ethernet speed of the AC1200R Router reach up to 1000 Mbps, which you will undoubtedly find if you connect devices through a LAN cable.
