It divides the communication protocol of the computer network architecture into seven layers, from bottom to top: the physical layer (Physics layer), the data link layer, the network layer, the Transport layer (Transport layer), Session layer, Presentation layer (Presentation layer), Application layer (application layer).

band (baseband) signal cannot be transferred far. to transmit the signal remotely, carrier modulation is required. It is transmitted after carrier modulation and then demodulated at the receiving end to restore the bit stream. This process is the modulation/Demodulation (modem ). the typical digital modulation methods include PSK, ask, and PSK. However, physical channels always have various kinds of interference, and modulation and demodulation itsel

Where are the locations of Wi-Fi when different technologies compete for the future of mobile highways? Multiple wireless technologies are competing to become the next-generation Transmission System for Mobile Video and collaborative business applications and services. WiMAX and LTELong-Term Evolution) are currently the leader in the WAN field. Qualcomm's ultra-mobile broadband UMB) technology ranks third, although it is eager to run at a speed above

ZTE 831 adsl modem Set 831:First, we need to refresh the 831 built-in software to 2. Version 79, which can be downloaded at www.zte.com.cn (how to click here)831 the IP address of the factory Ethernet port is 192. 168. 1. 1. In order to access 831 via telnet, we should set the address of a computer to 192 first. 168. 1. * Run ping 192.168.1.1 to check whether the access Traffic reaches 831. If no problem persists, run telnet 192.168.1.1 in DOS mode.

It is important to select a wireless network. To build a wireless network, you must first determine the wireless technology used before selecting a hardware wireless device. Currently, most applications use WLAN, Bluetooth, WiMax, and 3G.

However, their positioning is different. 3G is located in the WAN. Like 2G and 2G, 3G will continue to serve the public's mobile communication. 3G development must rely on large-scale network deployment, which takes a long time.

development must rely on large-scale network deployment, which takes a long time. Wireless Mesh is based on IP addresses and is located in the Metropolitan Area Network. It is flexible in networking and can be used in a small range first, and then gradually developed. It is more suitable for private network applications in various vertical industries. It entered the market before 3G, and it also has strong compatibility, so that it will be compatible with 3G in the future, to solve the problem
