devices with different functions are collected to one device? Or power the wlan ap with an PoE switch? Before answering this question, let's take a look at the process of wireless technology: the first generation of mobile phone technology emerged in 1985. However, due to the different standards and implementation methods of various countries, communication cannot be achieved, therefore, in 1982, a series of "Mobile Expert Groups" were set up to deve

links will eventually need to be upgraded to Gigabit Ethernet-if it is not between the Controller and the switch, it may be between the switch. In addition, you should consider using 802.11n for a 5 GHz Wireless return network-especially in areas where cabling is difficult, such as areas where new lines cannot or are not suitable for installation. Because of the larger capacity and faster transmission rate, 802.11n is more suitable for transmitting the return traffic typically transmitted by 10

only need four wires?3: The POE power supply uses four cables in the network cable to transmit electricity, so the M line is good to say, but the gigabit network uses eight lines to transmit signals, is it impossible to implement POE power supply in Gigabit Port mode? Zhang yianswer: Generally, the network cable is connected according to the wiring diagram of B. However, the same standard is used for the c

planned upgrade support 802.11n should also include an upgrade of the Ethernet switch capability to support connections from 1Gbps to 802.11 access points. This reduces the potential bottlenecks in any 802.11n client high-speed access. Power requirements Many of the 802.11 access points currently in use can be powered using Ethernet (Poe or 802.3AF). This technology provides up to 15 watts of DC power on standard 5 pairs of twisted-pair wires. 802.11

Verification of data cable installation has provided an effective tool for network owners and wiring personnel to ensure the integrity of the physical network. This provides a solid foundation for network reliability. With the emergence of Ethernet communication protocols and other services, such as Ethernet Power Supply-PoE, higher-level verification must be provided after the business is activated or moved, increased, and changed, or, after resolvin

of 11n networks will not be able to be truly realized. To avoid this problem, we recommend that you use the WA2620E (dual-band) + WX3024 Networking Mode for H3C. Because WA2620E can work both at GHz and 5 GHz, therefore, the GHz radio frequency can be reserved for 11G users, while the new 11n users use the 5 GHz band. In this way, users of the 11n and 11g are connected from two frequencies, and interference between them is completely eliminated. Users of the 11n and 11g can reach the highest ra

. At the same time, the diameter of the loop conflict can be calculated. Based on this theory, we can calculate the maximum distance that a signal can transmit before a minimum frame is sent. This is why the link span is limited to 100 meters. When the length exceeds 100 meters, the information packet that is damaged due to the conflict cannot be detected in a timely manner is transmitted and received by the recipient. The packet is forced to be discarded because it cannot pass the verification,
