What is wifiwi-fi) The IEEE 802.11b wireless network specification is a variant of the IEEE 802.11 Network specification. The maximum bandwidth is 11 Mbps. when the signal is weak or there is interference, the bandwidth can be adjusted to 5.5 Mbps, 2 Mbps, and 1 Mbps. The bandwidth is automatically adjusted to effecti

Wireless network technology is becoming more and more powerful. to master the RF communication technology, we will give you a detailed description of the wireless technology, suppliers are attempting to use "easy to install", "seamless connection" and other commitments to mask abnormal Wi-Fi physical layer signals. However, you need to use RF technology to manage a large wireless network, just as you must know that if the connection is used to build an effective lan. Knowledge of RF communicatio

Fast Ethernet is a new type of LAN. Its name is "Fast", which means that the exponential data rate can reach 100 Mbps, 10 times the data rate of standard Ethernet. It includes two technologies: 100BASE-T and 100VG-AnyLAN. 100BASE-T 100BASE-T is proposed by the high-speed Ethernet alliance composed of companies such as DEC, Sun, Intel, 3Com, and SMC. The goal is to speed up the speed of 100BASE-T. Many vendors launched products related to 100BASE-T by

society with over 175 members from nearly 0.36 million countries around the world. The organization is a leading authority in fields such as space, computer, telecommunications, biomedicine, electric power, and consumer electronics. Its standards include: electrical and electronic equipment, test methods, original devices, symbols, definitions, and test methods. OK. With the above basics, I will go back and learn about the standard wireless network protocols, including IEEE802.11b, 802.11a, and

Wireless RouterThe transmission rate is not as fast as described above. Why? Is it a false identification made by a merchant? Otherwise, let's take a look at the article for details. Wireless LAN, also known as WLAN, has become a networking method for more and more users.Wireless NetworkIt is easy to install and does not require rewiring. Therefore, it will not damage the original decoration of the home. Compared with wired networks, wireless networks are much more flexible. During use, we found

The use of wireless networks is no longer familiar to many of our network users. However, to improve the transmission efficiency of the network, we need to study it in detail. Many of our friends have found that our actual wireless router transmission rate is not as fast as described above. Why? Is it a false identification made by a merchant? Otherwise, let's take a look at the article for details. Wireless LAN, also known as WLAN, has become a networking method for more and more users. Wireles

It is especially suitable for campus networks with strict security access control and network environments that require flexible bandwidth allocation for users, it can meet users' convenient and secure network management needs. Based on the shared memory architecture, BitStream2125TM provides a switching bandwidth of up to 12.8 Gbit/s and a forwarding rate of more than 6 million packets per second. It operates on all 10 BaseT/100BaseTX po

Currently, there are many types of products available in the market, and you may encounter various problems when purchasing products. 1. Keywords: Port The LAN port and WAN port of the wireless device. If you do not have a WAN port, you cannot connect to the Internet. If you do not have a LAN port, you cannot connect to NICs, switches, and other devices in the wired LAN. Recommended Purchase: currently, most home wireless router

Recommended Purchase: currently, most home wireless router products provide four vswitch (LAN) ports and one WAN port. The port speed is generally adaptive to 10/100 Mbps, in addition, both have Auto MDI/MDIX (automatic crossover function), so that you do not need to know the network cable type and can automatically identify it. The LAN port can be used to conn

world, such as Nokia, 3COM, CISCO, Siemens, Alcatel, Paradyne, have successively launched ADSL products and are committed to the development of ADSL; many telecom companies and ISPs around the world have also promoted their respective ADSL Services. North America and Singapore are the first to officially open their business. Japan, South Korea, and other countries have entered the trial phase, china Telecom has carried out relevant network tests in Beijing, Shanghai, Guangdong, Fujian and other

Channel technology. 8 B10 NRZ (not normalized) encoding method is used to provide a valid baud rate of 1.25Gbaud. Therefore, it can provide a data rate of 1 Gbps at full speed.The 1000BASE-SX series uses low-cost short-wave CDcompact disc, optical disc lasers) or VCSEL (Vertical Cavity Surface Emitting Laser) transmitters, while the 1000BASE-LX series uses relatively expensive long-wave lasers. The 1000BASE-CX series intends to connect high-performance servers to high-speed peripheral devices u

transmission media, the twisted pair is at the transmission distance, channel width and data transmission speed are limited, but the price is relatively low. Twisted pair cables (referred to as twisted pair cables) are the most common transmission medium in the Integrated Wiring System. In the star network topology, twisted pair cables are essential for cabling. Twisted Pair wires can be divided into two categories: unshielded twisted pair UTP and shielded twisted pair STP. STP is divided into

equipment providers, such as network devices, D-Link, TP-LINK, trend, addems, and HP, have launched similar product solutions. This allows LAN users to share a printer in a wireless manner to effectively utilize printer resources, saving the trouble of wiring and making it easy to use. TP-LINK TL-WPS510U Such as TP-LINK reference price 850 yuan) is a single USB port wireless printing server, provide a USB 2.0 printer port, can be compatible with the mainstream USB interface printer on the marke

packet switching. If a vswitch can provide a maximum of 176 Gigabit ports and the declared throughput is less than 261.8 Mpps (176x1.488 Mpps = 261.8 ), the user has reason to think that the switch adopts a blocking structure design. Generally, the switches that both meet the requirements are qualified switches. For example: 2950G-48 Backplane = 2x1000x2 + 48x100x2 (Mbps) = 13.6 (Gbps) Equivalent to 13.6/2 = 6.8 Gigabit Ports Throughput = 6.8 × 1.48

[It168] Choosing a suitable broadband line makes your own Broadband Router even more powerful. Currently, common wide-line channels include XDSL, CM, fttx + LAN, PLC, DDN, satellite access, and microwave communication. Which of the following broadband access methods is better? XDSL XDSL refers to the digital user line access technology developed on telephone lines. Currently, it is commonly used in two types: ADSL and VDSL.① ADSL (Asymmetric Digital user line)ADSL allows asymmetric high-sp

to say, in many cases, our private bandwidth may be less than 64 KB. Why?In fact, China Telecom's ADSL is running on the ATM, and the bandwidth from the ATM to the Chinanet edge router is 155 M. Each edge router can connect 3000 users. If these users access the Internet at the same time, in fact, each user only has 50 kbit/s of bandwidth, that is, 7 Kbytes/S. In addition, with the attenuation of the router, the speed of the common Modem may end up.Of course, the above is just a hypothetical sit

The port priority discussed, the bridge priority is a two-byte (16-bit) value, an unsigned 16 is an integer with 216 possible indications, and the range is 0-65535. The default bridge priority is the median value of 32768, which is described using the 10 binary. Note:This book covers only the version of the IEEE Spanning
