. The signal scattering from the center to the surrounding area is used. Therefore, an omnidirectional antenna is used in the selection of the antenna to facilitate signal transmission in all directions so that all directions can receive the signal. The antenna that receives wireless signals at the edge must adopt a targeted
Currently, wireless dual-network technology is also popular. How can we build a complete network? The following articles describe the technical aspects of home applications.
The dual-AP function is not a dual-antenna function.
In order to facilitate wireless internet signal reception and provide efficient and unobstructed wireless signal transmission, wireless manufacturers have launched wireless router devices that support dual-

1. common hardware faults:
(1) Adjustment of base station coverage
When the signal in the base station coverage area is poor, you can increase the coverage range by raising or downgrading the antenna height, checking the an

Eliminate misunderstanding: the more wireless route antennas, the better the signal? (1)
A strange consumption habit exists in the daily consumption behaviors of most consumers. when the price is almost the same, consumers prefer products with a "large quantity. In addition, the phenomenon of follow-up is also very serious. Many facts did not go to the research, and they took the plunge. "I will buy more products if I buy more products ". Fans of the "Car god party" and "heavy doors" are the mo
There are very few FM searching machines. This problem should be divided into two categories,
Category 1: If you manually adjust each station, you can hear clear radio stations. You only need to change the stop threshold of the station
The number of search sites has increased,
Another type: manually adjust to a radio station with poor signal, and compare it with the FM of the brand mobile phone, it is found that the FM effect is obviously worse than that of the brand mobile phone, for example, t
previous generation of wireless devices do not need to worry that existing devices will be eliminated.
In terms of security, D-link dwl-g122 supports Wi-Fi Protected Access (WPA), provides the necessary security protocols and tools to provide confidential communications to you and other wireless users, such as access to sensitive information or dynamic encryption of data transmission. WPA authenticates users by automatically changing the secret key within a regular interval.

multi-dimensional transmission scheme: one single RF channel is used to send and receive two or more signal streams. As a result, the wireless communication system can transmit data twice or more in a channel. In the system, use more than one high-integration RF upconverter) and antenna to transmit these multiple signals, and there is also more than one high-integration RF downconverter) and the antenna to

We can also use the Network Stumbler software for scanning to see which wireless signals exist nearby and which channel is used. Then modify our own wireless channels to avoid duplication with other channels.

The distance between the wireless router and the network card is too long, in this case can only be solved by a different configuration of the appropriate antenna.
The wireless router and the network card have the obstacle influence, sometimes also can cause the disconnection breakdown, for instance the indoor complex environment, the wall, the furniture influence. So try not to go through walls over three floors as much as possib

You can support business with different quality requirements, such as voice and packet data, and ensure high quality and perfect coverage. (2) High spectrum efficiency. WCDMA can efficiently use the radio spectrum. Since it uses single cell multiplexing, frequency planning is not required. The network capacity can be greatly improved by using the layered cell structure, adaptive

In decibels, the logarithm is taken first, and the value is much smaller.(2) convenient operation. When the amplifier is cas
