Wireless Broadband Router Internet really brought us, without wiring, allows us to share Internet resources, many office director of the Computer Department will purchase, installation and set up Wireless, Router, in some hundreds of feet of office, use usually does not appear to trouble. Some thousand square feet of office or residential, there have been reports of poor wireless signal reception, this problem partly stems from the use of improperly. The first inappropriate Wireless Broadband UltraXtend Stiftung Warentest Router at random on the obstacles, usually like to put as right next to the file cabinet top, or other office equipment, the use of this placement method will lead to send and receive signals of the wireless antenna equipment block, thereby reducing the coverage, so we must ensure that the equipment is placed in the open position or height, which improve the send and receive radio signals. Employees and file in the office will continue to move around and be moved, which would hinder the spread of the wireless signal to place the equipment is the height Another benefit is to reduce the opportunity to be blocked between the Wireless Broadband Router with the PC / USB wireless devices.

In addition to the Wireless Broadband Router on the open, we can still use other means to increase coverage, some offices will equipment hanging on the walls of the relatively high and its location is usually a result of accommodating the telephone line or other Internet settings the side near the office, this is a big mistake, first, the walls (especially concrete reinforced walls) will block the wireless signals sent Wireless Router random antenna for the whole to the antenna around 360 transceiver , such as Wireless Broadband Router on the office side, but it will waste half the energy, that is, reducing a half of coverage area, so the best Wireless Router is placed near the center point in the office.

Should be Wireless, Broadband Router in the office of the nearly central point, usually only on the location of the false ceiling, but if placed on the ceilings above the wireless signal or how many will be smallpox, stents and even beam block, it is best to share on the ceilings under significant left hand side the following figure, there is resistance to unsightly addition, are not prepared for such an installation in the design, installation, thus there will be a very high difficulty.

In addition, many of Notebook Computer are built-in wireless, so the two issues, a lot of people have overlooked is the noise of the antenna will be sensitive to the main floor, the experimental data show that noise can be as high as 3 dB, followed by board more or less less will impede the wireless signal transceiver, and an external antenna can be avoided built-in antenna to produce the problem. At present a lot of computers have antenna on the back of the display, wireless receiver capability than the old generation of built-in wireless card, Notebook, Computer improved a lot.

Another thing to note, 2.4GHz for the extremely high frequency signals, the cable attenuation is very large, especially the high-frequency lines of a small external antenna is usually used 3mm diameter young body, the length of one meter lead to a few dB of signal attenuation, so an external antenna the cable can not be too long.
