Comparable to optical fiber! Wi-Fi transmission speed up to 100 Gbps
What is the maximum transmission rate of current WiFi? Is the 11ac technical standard three-frequency 5300 Mbps? Or 11ad 7 Gbps? Or 11ax's 10 Gbps? The answer is 100 Gbps! Yes, this is comparable to the opt
Is there any trouble when the room is full of Network cables? Do you want to make vrouters wireless? 7 Gbps streaming media wireless transmission, WiFi declared war, dear friends, it is not long before you say goodbye to the full room network cable!
In the next year and a half, we will see the rapid development of WiFi (technology that connects PCs, handheld devices, such as PDAs, mobile phones, and other terminals wirelessly) technology, wireless ev
Optical fiber is outdated? Gbps Space Optical Communication in the UK!
According to foreign media reports, researchers at the University of Oxford have achieved free-space optical communication at a rate of up to Gbps. Such optical communication technology does not need to use optical fiber. The researchers pointed out that the maximum rate of the communication system can reach 3 Tbps.
The study, led by
A network testing team of Siemens Germany, supported by the European Union, recently announced that they have successfully tested the passive optical fiber network. This test not only made a new breakthrough in the speed of data transmission connected to the home or office, but also expanded the transmission coverage.
On the passive optical fiber access test network, the data download rate tested by the team reached 10 Gbps, and the data upload speed
The first test result of the Wi-Fi substitution LiFi is released: 1 Gbps
Light Fidelity (Li-Fi) is a fast-paced wireless transmission of optical pulse information. As a future replacement of Wi-Fi signal transmission networks, Light Fidelity is in the process of rapid development. Velmenni's startup recently successfully deployed the Li-Fi technology in a small environment. Although it proved that the technology was not the first time, it was the f
LocVPS, a Chinese VPS host provider, has many other host brands, such as Weixiang host and HostXen, which are also the same host Brand of the same boss. Their products are similar, to some extent, we can cover the user market with a high probability of packaging different brands. The LocVPS platform uses Xen-based VPS host products, including VPS hosts for data centers in Sha Tin, Hong Kong PN, MC, and Peer1.Currently, LocVPS provides upgraded configuration of the CN2 line in Sha Tin, Hong Kong,
After the Android phone successfully connects to the GHZ wireless signal of the 11N router, the current wireless speed is usually 72 Mbps (or 65 Mbps) on the phone, as shown in the figure below:Note:: The wireless rate cannot be viewed on iOS mobile phones.This is because the Wi-Fi module of the mobile phone only has one built-in antenna and only supports 20 MHz bandwidth. Therefore, after the mobile phone
Mbps and MB/s represent a different network transfer speed, and MB/s is 8 times times the Mbps.MBPS=MBIT/S is the abbreviation for megabits per second (Million bits by second). BPS (bits per second), which is the common unit of bit rate, bits/sec, bits/sec, transfer bits per second, data transfer rate .The size of the file is usually referred to as 8MByte. BYTE (byte) is a unit of measurement used by computer information technology to measure storage
between B and B.2. What is the download speed of 2 Mbps?
First:2 m/s = (2*(10 ^ 6)/8 B/S = 250000 B/S
Explanation: we need to convert the 2 Mbit/s network speed to the download speed. 2 Mbit/s = 2*(10 ^ 6) B/S, at this time, we get the data volume of B (B/S) transmitted per second (in lower case, bit.
Because a B represents 8 B, 2 m/s = 2*(10 ^ 6)/8 B/S = 250000 B/S, at this time, we get the amount of B transmitted per second (B/S, note that it is ca
Among the many Internet Access Technologies, the emerging Power Line Communication technology is particularly eye-catching. The power supply's online network speed can reach 200 Mbps. This absolute advantage will threaten the Traditional Ethernet access power cord communication technology, the basic principle is to use existing power lines to achieve high-speed transmission of data, voice, images, and other multimedia business signals, and load data s
When we choose VPS, Server host, we often see the common MB, GB, Mbps, and so on some of the labeling units. Most of us will probably know MB (megabytes), which is much larger than the amount of memory we often use. But if the bandwidth is involved in Mbps, it may be a bit difficult to understand, such as we often see that there is 2Mbps bandwidth, many people will understand that 2MB, and then use the file
Oracle 12C r2-new features-pdb disk I/O (iops,mbps) resource managementIn previous versions, there was no easy way to control the amount of disk I/O used by a single PDB. As a result, a PDB may run out of disk I/O and affect the performance of other PDB in the same instance. The Oracle 12c R2 can control the amount of disk I/O used by the PDB and is more harmonious with multi-pdb.1 Introduction to I/O parametersSome of the following parameters can be
Network server bandwidth Mbps, MB/s, MB/s differenceThe meaning of MB/s is megabytes per second, MB/s means megabits per second, the former refers to the number of bytes transmitted per second, the latter refers to the number of bits transmitted per second. The two are completely different.The so-called 10M bandwidth, in fact, refers to 10Mbps (megabits)Computational bandwidth theory fastest download speed: 10÷8=1.25mb/sThe fastest download speed for

Digital Subscriber line or DSL is a technology that provides digital connectivity via copper or local telephone networks. Its history dates back to the 1988, when an engineer at Bell Labs designed a method that allows digital signals to be loaded
widely used technologies in the computer network field, most switch products now support this technology, such as 3ComSuperStack3Switch4900 and the above mentioned switch. When purchasing a gigabit network card, pay attention to whether the storage forwarding mode is supported to ensure the normal operation of the network. Direct-through forwarding means that the switch has started to forward data before it receives the entire frame, which can reduce the latency and is rarely used at present.

specific direction and runs independently without any other client devices generating traffic? The answer is self-evident. No.
Cost is always king
From a business perspective, it is hard to believe that someone is willing to spend money on reaching the 10GbE edge for all access points, and no one is willing to spend money on Cat7 cabling of a higher level (to be honest, Cat 6 may be more reasonable ). It is clear that the cost of deploying multiple copper cables for each access point with Link
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:

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.
