stronger than the barrier penetrating ability and the signal is relatively stable. Wireless coverage in the building within a radius of 20 meters, only a wall, two walls will not signal. So look at the pattern of the house, it is recommended to buy multi-frequency, so the signal strength is better, the signal strength is weaker than the situation under the network will be greatly affected, and if the same band of wireless networks overlap each other, may cause the mutual interference of signals
1. Standby interface, pull from top down;
2. Long Press "WLAN" icon;
3. Select the WLAN network to connect to;
4. Enter the password and click "Connect". (When the network connection is successful, the WLAN feature icon will be displayed in the wlan list on the top right of the phone screen.) )
Note: If you are prompted for "validation errors," This is due to the incorrect connection password entered, it is recommended that you confirm the correct password

Whdi (Wireless home Digital Interface, the Wireless Family Digital Interface) sets a new standard for wireless high-definition video connectivity. It provides a high quality, uncompressed wireless connection. The MIMO technology and the OFDM modulation method can achieve up to 3Gbps transmission speed.
Working in the 4.9ghz~5.875ghz band, 20MHz or 40MHz channels, in line with the global 5GHz spectrum, the range is within 30 meters, can penetrate the
noise in a data unit), thereby improving performance.
2, utilization is too high
In the case of active wireless network users, or when users are operating some bandwidth-intensive applications (such as downloading large files), the application of the network is likely to reach the maximum capacity of the access point. Under this condition, the retry rate may be relatively higher (more than 10%), even if the signal strength is high and the noise intensity is low, it can affect network perform
time Wave chart shows the signal strength (in db) of each wireless router over the last 5 minutes. Then there is a graph of each 2.4GHz and 5GHz channel, showing the strength of the existing signal and the width of the channel used by each wireless router.
Find your wireless router name, according to the corresponding color lines, to see its real-time trend. If this line is relatively flat, it shows that the current wireless router signal is relativ
design, there are still some models with external antennas, and usually can be upgraded. Hawking technology, for example, provides a similar product that can enhance signal strength at least 2dBi to 15dBi. This external antenna can be compatible with most of the routers with external antennas, ranging from 40 U.S. dollars to 100 U.S. dollars (about 245 to 613 yuan).
8. Buy a dedicated repeater
The dedicated wireless network repeater can effectively extend the coverage distance of
coordination with the base station (base station,bs) or access point (Access Point,ap). In 1999, two additional versions were added: 802.11A defines a single, 5GHz ISM bandThe data transfer rate can reach the physical layer of 54mbit/s, 802.11B defines a physical layer on the 2.4GHz ISM band but with a data transfer rate up to 11mbit/s. The 2.4GHz ISM Band is common to most countries in the world, so 802.11b is the most widely used. Apple called
little louder to get the other person to hear it. Of course, it also means that you are doing a thorough investigation of the site in order to determine the optimal number and location of Access point AP. 4, the correct configuration parameters If you are deploying a 802.11g network, you should adjust the AP frequency so that it can avoid the frequency of potential interference signals. But this method is not always effective, but it is worth a try. For example, microwaves typically have a

In the smartphone age, WiFi is clearly more popular than data traffic. And a number of high-end mobile phones such as the iphone, HTC one M8, millet 4, etc. are used dual-frequency WiFi design, which makes the phone in the WiFi reception better.
What do you mean, double WiFi?
Dual-frequency WiFi refers to a device that supports 2.4ghz/5ghz dual-band wireless signals and supports a 802.11a/b/g/n full wireless network, which belongs to the fift

Power 5 's high-end server code-named "Cavalry" ("Squadrons"), IBM wanted the CPU to be like the Knight Colts charge as sweeping the UNIX server market, the result seems to
To explore the application of wireless LAN, we should first analyze the technical characteristics of WLAN, because it is the technical characteristics of WLAN that determines the application range of WLAN. By comparing the wireless LAN with the cellular Mobile communication Network (GPRS and 3G of 2.5 generation), we can find the application location of WLAN.
First of all, from the working band, the frequency of cellular mobile communication network needs to be licensed, pay fees, strict govern
stimulated, many manufacturers began to pour into this field, want to show their fists.
Currently, wireless HD transmission has several mature technologies, namely, low latency WHDI technology, high bandwidth wirelesshd technology, Intel Widi Technology, Alliance numerous WIGIG technology, and reluctantly dine DLNA technology.
Whdi's full name is "Wireless home Digital Interface", the Wireless family digital interface. The technology is based on Whdi autonomous technical standards, worki
that the layer uses the 5GHz frequency band, uses the orthogonal frequency division modulation data, the transmission rate range is 6mbps~54mbps, can satisfy the indoor application, but can satisfy the outdoor application. The newly introduced 802.11g and 802.11b operating bands are the same, are running in 2.4GHz, and both are fully compatible, in the transmission rate has been improved, can reach 22Mbps, even 54Mbps.
To improve the service quality
widely used in the technology is 802.11 families, it is the first wireless LAN standard published by IEEE in 1997, and now the 802.11b, which is frequently mentioned in the media, is approved in September 1999, and it is also called Wi-Fi (sounds a bit like the music enthusiasts say Hi-Fi), Can support a shared access rate of 11Mbps , similar to the 802.11A technology, it uses the 5GHz frequency band, its speed is as high as 54Mbps, the frequency div
Today, MediaTek announced today the launch of the 802.11AC high-order wireless network single chip MT7615. This chip supports multi-user multiple input multiple output (Mu-mimo, multi-user multiple-input multiple-output) and transmission beam forming technology.
MT7615 runs in the 2.4GHz and 5GHz dual band, regardless of long distance communication, at the same time is one or more users, users can enjoy the ultra-high data throughput of wireless netw
connections, but it is still difficult to carry more and more data, video, voice, and so on, and most people will choose free Wireless LAN. In households, such traffic is not popular with residential broadband access. In the work area, Gast recommends using an employee-specific channel to connect to the company's Wireless LAN network, or at least to the portion of this setup.
Prepare for 802.11AC and 802.11AD standards

Many of these products, such as the Alcatel Company's A9800 system, NEC's Dmmass, Datang's PMP1560, and IRC's June, have been operating at a 15ghz,19ghz,24hgz and higher frequency. System coverage can be 5-60 km (without relay station), can also be 500--600 km (plus relay station). Rural areas, deserts, mountains and islands are useful for such products.3, the use of satellite communications technologyAs we all kn
