Nowadays, the requirements for the aesthetics of the environment cause the need for miniature, but high-functionality cable trunks. This is necessary in order to transmit a large amount of digital information over long distances. To achieve such goals, the latest generation devices are used - wireless HDMI extenders , which make it possible to transmit and receive digital information with constant quality indicators. Let's take a closer look at the description and operation of wireless HDMI extenders.

Features and purpose

The HDMI Wireless Extender has the following principle of operation - convert a digital signal and then transmit it wirelessly, without any archiving or delay, online. The signal operates at 5Hz and is similar to Wi-Fi. Device complete set provides for a special sequence of actions that allows you to automatically select free frequencies, which does not give rise to the risk of overlapping radio waves coming from outside.

During use, this device does not have a negative impact on humans and the environment, since it does not contain poisonous particles.

Such devices have the following positive characteristics:

• fast data transfer;
• no compression, deflection, signal strength reduction;
• immunity to electromagnetic interference;
• compatibility with a variety of HDMI devices;
• similar to the extension cord of variant 1, 4 of earlier production;
• the range of action is 30 m;
• unhindered overcoming of walls, pieces of furniture, household appliances;
• with support for Full HD 3D and multichannel sound;
• available remote control function and remote control device;
• simple and comfortable use;
• no need to customize;
• Supports up to 8 HDMI transmitters.

The HDMI device can be used in an apartment, as well as in a small office space, shopping pavilions, exhibition spaces, meeting rooms . The miniature device incorporates a small transmitter and receiver in its design, endowed with the ability to function regardless of position. For the device to work, you need to connect its elements to the contacts of the transmitter and receiver. The digital signal is transmitted without interruption, bypassing obstacles that does not require laying of a cable.

The use of such an extension cord makes it possible to prevent the accumulation of cords and free up part of the room for other purposes.

Varieties

Standard devices are considered inertial and have the ability to transmit a signal at a distance of up to 30 m.

To transmit video and audio information over a distance of more than 60 m, devices are used over "twisted pair " with the help of them, a signal is transmitted at a distance of up to 0, 1 - 0, 12 km. The process is carried out without distortion of information, quickly and without the need for archiving. Most devices are characterized by the presence of options 1, 3 and 1, 4a, which support 3D size, as well as Dolby, DTS-HD.

Based on the design features, there are several types of HDMI signal extenders over "twisted pair", which differ among themselves in terms of the level of mechanical protection and protection against interference.

In small rooms where there is a lack of space, there is no way to stretch the cable system, an acceptable model of extender is wireless, which transmits a digital signal using wireless standards (Wireless, WHDI, Wi-Fi) . Information is transmitted up to 30 meters, overcoming various obstacles. The manufacturers present the latest developments in the extension cord, which can be used for any purpose related to the transfer of information. To transmit information over long stretches of up to 20 km, there are extension cords with optical and coaxial cable where audio and video signals are not deformed.

Operating rules

When using an HDMI Wireless Extender, follow these guidelines:

• do not disconnect the device from the power supply during use, keep it away from flammable surfaces;
• to recharge the device, you should use the charger that comes with the package; damaged charger cannot be used;
• you cannot use the extension cord itself if it is damaged or has any malfunctions;
• no need to look for the causes of the malfunction on your own and try to repair the product.

In addition, the device should not be stored in rooms with a high degree of humidity … Avoid contact with water and other liquids.
