the wireless node equipment, and provide a good working environment for the wireless workstation. Once we cannot find the local wireless network node name in the wireless network connection attribute interface, we need to carefully check whether there is a signal interference source between the wireless network card and the wireless node device. For example, we can check whether there are high-power household appliances like televisions, refrigerators, air conditioners, and so on in the vicinit

For wireless network technology, many of us do not know what problems occur when the connection fails. How can we troubleshoot and diagnose the problems? Here we will answer your questions. When using wireless networks at home or in public, the network may be disconnected without warning. For us, I am afraid it is no more frustrating than this. Of course, this is also a very common network problem. Next, this article will detail the problems that may occur and tell you how to solve them. Wi-Fi c

router for each layer. In practical application, the indoor AP coverage can be up to 30 meters. The actual usage rate of 802.11b is only about 40% of the nominal value, and the converted data transmission rate is about 64/128 kb/s. If it is set to-bit WEP encryption, the transmission rate will be further reduced, therefore, you must pay more attention to interference during use and try to stay away from microwave ovens, cordless phones, and Bluetooth

Internet separately. If the line is also dropped, you can ask the ISP to check the quality of the incoming line. Check whether there are cordless phones around ADSL), air conditioners, washing machines, refrigerators, and other devices with serious electromagnetic interference. If so, remove them, do not share a power cord. voltage instability may also cause some MODEM to fail ). You can use the following common methods to determine the fault locatio

: Experience Sharing Generally, the 802.11 series of wireless network products have good compatibility. Most wireless network adapters and wireless routers do not have compatibility problems. But for stability considerations, for high requirements, I suggest using the same brand of wireless routers and wireless network interfaces. The load-bearing wall of reinforced concrete has a strong obstacle to wireless signals. Therefore, for the "duplex" residential and Villa-type home environment, the be

users.Another vendor that publishes a SIP-based solution is Avaya. Avaya has expanded its SIP functionality in some products. Avaya's IP Phone and messaging software have now improved, such as expanding compatibility among multiple vendors, including fully supporting Cisco IP phones. In addition, Avaya's IP software now includes the SIP protocol, which doubles the number of SIP sessions supported without increasing the software fee.Other News from the VoiceCon exhibition is that SpectraLink has

The disconnection fault of youxun wireless router is generally caused by two reasons.I. Wireless disconnection, And the wired connection is very stable (1) check whether the wireless router of youxun is encrypted and set the encryption method to WEP; (2) check whether the wireless network card and the youxun wireless router are used in the same room. If there is an obstacle similar to the wall, the wireless network card and the youxun wireless router can be used at close distance without obstacl

The remote control has a microphone and a receiver, which can be used as a Skype phone. The connection via the bluetooth technology is equivalent to the combination of the Bluetooth headset and the remote control (either QQ or MSN). It can also be used as an ordinary phone, similar to cordless phones. 5.

11 channels are independent of each other. On the other hand, devices that are not compatible with the WLAN 802.11 standard are also using the 2.4g ism public band. We are familiar with Bluetooth headsets, USB wireless mouse keys, mother-computer cordless phones, ZigBee home or industrial automation control, microwave ovens, and other work in the 2.4g ism or nearby frequency band. When they are enabled, they will interfere with signals sent and recei

For example , at/T operates near 4500 Central Office in the United States , and a typical office in a large city is serviced by Cable and 10 million cordless phone users, as well as thousands of businesses.

In fact, if multiple users are connected at the same time through a single point,Bandwidth will be shared by multiple users, Wi-Fi connections will be reduced to only hundreds of kb/s, and Wi-Fi signals are generally not affected by wall blocking, but the effective transmission distance within a building is less than that of outdoors.3) The original IEEE802

Next we will give you a detailed introduction.I.

position of L2CAP In the Bluetooth protocol stack is as follows: That is to say, all L2CAP data is transmitted to the remote device through HCI. Most of the data in the upper-layer protocol is also transmitted through L2CAP. L2CAP can send command. Such as connection and disconnection. The following is an example of command: Connection Request: In this case, we need to note that The L2CAP uses The L2CAP Connection Request (Connection Request) Command. L2CAP can reuse connection requests

worldwide. The data rate of Bluetooth is 1 Mb/s. The Time Division Duplex Transmission scheme is used for full duplex transmission. Use the 802.15 protocol. The ISM frequency band is an open frequency band for all radio systems. Therefore, an unpredictable interference source may occur when a frequency band is used. For example, some household appliances, cordless phones, car room door opener, microwave ovens, etc., may be interference. To this end,
