What is the difference if any between AUX and main antennas?

In Teltonika networking devices, one mobile antenna connector is “MAIN”, while the another one is “AUX”. When “3G” technology is used, “AUX” antenna is used as “diversity antenna” for error correction. Its effects are mostly noticeable in poor mobile signal strength areas.

What is AUX and Main?

Answer. The AUX/DIV Antenna is used for a variety of tasks, including but not limited to: Used to achieve 4G LTE Connectivity when paired with the MAIN antenna(s). Use of both MAIN and AUX/DIV is required for best performance and predictable behavior on LTE.

Why do WIFI cards have two antennas?

A dual Wi-Fi antenna is a pair of identical antennas on a wireless router or Wi-Fi-equipped device, intended to eliminate signal fading and dead spots. A dual antenna on either the router or the end user device offers a solution to the problem of Wi-Fi fading, dead spots, and drop-outs.

What are the two wires on WIFI card?

The pins are actually co-axial cable connectors which connect the 2 wires (signal wire and shield) in each of the cables to the connector on the WLAN card.

Can a WiFi card work with one antenna?

Often you can just run the extra antenna wire along the bottom innards of the laptop instead of up around the screen–that’s better than. Also consider your present antenna may not be dual-band but 2.4GHz only. I bought a pair of these antennas from ebay which should work fine.

Does WiFi and Bluetooth use the same antenna?

Yes, almost all devices that have Bluetooth and WiFi have only one 2.4GHz antenna. This is the case for devces that contain combo radio chips as well as those that have separate Bluetooth and WiFi chips. An RF switch is used to ensure only one radio is connected to the antenna when either device is transmitting.

What color is main and aux?

When installing: Plug the gray cable into the jack labeled MAIN on the card, and the black cable into the jack labeled AUX.

Can I use WiFi without antenna?

All wifi devices have antennas. That is how they are able to transmit wifi signals. Without antenna there can be no wifi. That is they can radiate signals in all directions.

Can a wifi card work with one antenna?

Do wifi cards need antennas?

Yes, wifi chips do not have integrated antennas and thus require them. FYI, wired Ethernet will always be faster then wifi, both is mbps and in ping/latency (time it takes to send data to the server).

Does wifi and Bluetooth use the same antenna?

Are two wifi antennas better than one?

Yes, all other things being equal, multiple antennas will increase signal range. Primarily by using beamforming they increase signal strength towards the target, which means the signal to noise ratio is strong enough to still send and receive data at a longer distance.

What are the blue and white cables for on my laptop?

Usually the coloured cable (in this case blue) is the main antenna to the wifi card. The white cable tends to be the auxiliary (backup) cable. Certain laptops like Acers have problems where the antennas run through the monitor hinges and get damaged over time.

How does the WiFi signal come from the antenna?

The WiFi signal coming from the antenna is only changed based on the design. More power is done by increasing the radio strength. For example, when a directional antenna dBi rating gets higher its focusing the signal beam into a more narrow path. By narrowing the path in which signal it let out, it allows for more range to be achieved.

Why do some cards have two antennas on the back?

On some cards the second antenna is for Bluetooth, which is also 2.4GHz (one reason why the two antennas are the same length).

Do the antennas on my laptop have two different WiFi frequencies?

No. Both are for both frequencies. These antennas are primarily designed to work with 2×2 WiFi chipsets. That means the laptop can concurrently maintain two 2.4GHz streams and/or two 5GHz streams. The two streams work together to improve reliability and, at least in theory, boost peak performance.
