designed for the sequence, M sequence, and RS code. These pseudo-random code sequences are implemented through the shift register and feedback structure. The structure is simple, the performance is stable, and synchronization can be achieved quickly. They can achieve a long period of time, and the relevant characteristics of hamming are also good, but when there is human intentional interference (such as tracking interference after the prediction code sequence, these sequences have poor anti-in
routers currently work in this band. Because of Other Wireless frequencies, its overall bandwidth improves the overall data transmission rate and its transmission distance is far away. With the development of technology, various manufacturers can make GHz wireless products more compact and reduce power consumption.
Devices with the same frequency interference
Currently, most of our users use wireless networks in the GHz band. At the same time, wireless mouse keys, wireless headphones, and Blue
scanning or similar work is required in the warehouse, and the network throughput requirement is not high. In the office environment, it is often counterproductive to force the launch device to cover farther distances. A better choice is to place the launch device on the wall of a small compartment.3. Avoid band congestionAlthough major chip vendors are gradually suspending their support for the 802.11a wireless standard, Newman recommends that this standard be used whenever possible. The 802.1

But one problem still haunts Wi-Fi;There is nothing more than users complaining about Wi-Fi performance is not stable, coverage is not good, often drop the network manager to crash. Addressing Wi-Fi, an invisible and changing environment, is really a problem. and radio frequency interference is also a culprit.RF interference com

It is based on a Java architecture that transforms applications and data written in markup languages such as HTML and XML into formats that can be recognized by wireless devices such as WML, HDML (handheld device Markup Language), and imode, so that The information on the Internet can be accessed via handheld devices.

frequencies on the 802.11b network. These tools can also detect cordless teleconference or close-range wireless systems that interfere with 802.11a networks.
The AiroPeek and AirMagnet solutions provide alarm functions to promptly notify network administrators of potential intrusions. Some analyzer is developing towards pure security tools. For example, the WaveRunner tool provided by Fluke focuses on signal strength, encryption, and other informatio
networks and short numbers for different remote networks. It provides customized services for enterprises and telecom-level services for enterprises to improve their image. Launched in combination with cordless phones and corporate color rings is a good business that is welcomed by small and medium-sized enterprises, which not only brings considerable business income, but also hopes to increase the installation rate by more than 2%. Like NP, the sign
radio technology, you can use an average power less than 1 MW to cover a few miles, or even use a low-gain antenna. It is particularly valuable that it has low Interference Characteristics and strong multi-path interference resistance to other wireless systems. It is easier to implement than to build a common spread spectrum system, with a low cost. It is precisely because of the above features that the UWB communication technology has been widely used in personal communication, intra-building
or use multimedia applications, which requires a solution with higher performance. Therefore, your organization is subject to the decision to migrate to 802.11n. Therefore, consider your needs and select the right technology from the very beginning.
RF interference
Some devices, such as 2.4 GHz and 5 GHz cordless phones, microwave ovens, and adjacent wireless networks, can cause destructive RF interference and reduce the performance of wireless netwo
GHz or 5 GHz band. Compared to the GHz band used for cordless phones or microwave, the 5 GHz band is less crowded, it is suitable for the transmission of sensitive data with delay, such as audio and video.
The WRT320N comes with the Linksys EasyLink Advisor (LELA) software. The software helps users connect to and run networks while keeping the networks updated and secure. The random installation CD is applicable to computers on Macintosh and Windows
network. If there are no other wireless network nodes nearby, only one network should be listed here. Otherwise, other nearby wireless networks will also be listed. Next, click "attribute" to activate "Data Encryption (WEP enabled, enter the encrypted string in the "Network key" and "Confirm network key" columns below, and then click "OK ", the wireless network adapter can be correctly connected to the wireless network node.
5. Experience Sharing
Generally, the 802.11 series of wireless network
the received signal will be 4 dB after a plank, 8-15 dB after a brick wall, and 15-30 dB after a reinforced concrete wall. This is why a wireless router can pass through three brick walls and cannot pass through a reinforced concrete wall, because the latter can almost completely absorb the energy of electromagnetic waves.
Second, 2 to 4 GHz devices in the same frequency band as 802.11b/g, such as wireless cameras, microwave ovens, Bluetooth, cordless
object is large, the Put request can be grouped by multiple Put requests.

The operation code is 0x03.Ii. Audio and Telephone Control Protocol 1. Framework
Bluetooth Audio is shown in the Protocol Stack: audio is synchronized through baseband transmission and is implemented for connection groups. It is not provided in a standard form and is not part of the protocol stack.TCS_Binary is a binary encoding instruction set based on group calls. It is located on top of L2CAP. Impleme

Many protocol analyzer can differentiate access point locations and share data through software ing. Among them, the SitePlanner tool provided by LANFielder can display the three-dimensional graph of the network; the ing software BirdsEye provided by BVS can output geographic data in the form of workbooks; the AiroPeek and OptiView schemes can automatically draw
compatibility. Most wireless NICs 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, the best solution to the "duplex" residential and Villa-type home environment is to configure a wireless router for each layer. In practical application, the indoor AP
integrates and improves existing wireless communication standards: for data communication, the TCP/IP transmission protocol in the standard is adopted. For voice communication, the digital enhanced cordless communication standard is adopted. However, this standard is incompatible with 802.11b and occupies the same GHz frequency segment as 802.11b and Bluetooth, so it has great limitations in the application scope, more is used in the home network.
Th
carefully considering the requirements, you can start to implement them correctly. In this way, you can choose the right technology at the beginning.
