1, router ac and ax difference frequency range is different ac wireless charging chip : 8011ac support 5GHz. The 8011ax supports 4Hz/5GHz. The highest level encoding is different: 8011The ac supports 256QAM. The 8011ax supports 1024QAM. The maximum physical layer rate is different: 8011ac is 9Gbps. The 8011ax is 6Gbps. ac. According to the inquiry on the official website of the Universal Connection, the ac wireless charging chip , ac is a double gigabit router ac wireless charging chip , ax is a single gigabit router, ac double gigabit coverage is large, and the wall effect is better than ax single gigabit.
2, wireless network standards are not the same, the rate is not the same, the function is not the same. There is noLine network standard, AC is 8011ac standard wireless router, also known as WIFI5 router, its rate is higher, but the transmission distance is shorter. AX is the 8011ax standard wireless router, also known as WIFI6 router, its speed is faster and the transmission distance is longer.
3, speed, stability. According to the query Zhongguancun online network, the router AX standard is faster than the AC standard, the maximum speed of the AX standard is 6Gbps, while the maximum speed of the AC standard is 9Gbps. The AX standard is more stable at high density, high concurrency, and can connect more devices at the same timeWithout affecting speed and stability, AC standard stability is poor, and network speed will be affected.
4, AC and AX are both network devices, but they differ in function, performance, and purpose. Routing AC is commonly used in large enterprises and data centers. It provides rich network functions and supports multiple access and device management modes. Routing AX is primarily used in homes and small businesses, with a simpler interface and features that support a variety of smart home controls and Internet applications.
Because the energy is transmitted between the charger and the electrical device by inductive coupling, the two are not connected by wires, so the charger and the electrical device can be achieved without conducting contactsDew. Wireless charging mainly uses the principle of electromagnetic induction, magnetic resonance and radio wave technology.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
The principle is to convert environmental electromagnetic waves into current through the circuit to transmit current. This way transmission distanceThe distance is greater than 10 meters, suitable for long-distance low-power charging, and can also realize automatic charging anytime and anywhere. WiFi wireless charging. It mainly consists of two components, one is a Wi-Fi access point (router), and the other is a customized charging sensor.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
ac is mainly based on 8011a, which continues to work in the 0GHz band to ensure downward compatibility, but the data transmission channel will be greatly expanded, increasing to 40MHz or 80MHz on the basis of the current 20MHz, and may even reach 160MHz. Coupled with an actual frequency modulation efficiency increase of about 10%, the theoretical transmission speed of the new standard is expected to reach up to 1Gbps, more than three times the 300Mbps of the 8011n.
ac and 8011nIn terms of core technology, the 8011ac is built on top of the 8011a wireless Wi-Fi standard, including the 5GHz band that will use the 8011a. However, in the setting of the channel, the 8011ac will follow the MIMO (multiple input and multiple output) technology of the 8011n, laying the foundation for its transmission rate to reach 1Gbps.
IEEE 8011b is a standard for wireless LAN. Its carrier frequency is 4GHz, providing multiple transmission speeds of 5 and 11Mbit/s. IEEE 8011g was adopted in July 2003. Its carrier frequency is 4GHz (the same as the 8011b), the original transmission speed is 54Mbit/s, and the net transmission speed is about 27Mbit/s (the same as the 8011a).
Different transmission speed 8011ac is a wireless LAN that improves the flux through 5GHz frequency, theoretically speaking, it can provide a minimum of 1Gbps bandwidth for wireless LAN communication, and the theoretical maximum of 8011n is only 600Mbit/s, and the two-lane is used in 8011n. To the 8011ac it used 8 lanes, compared to the elevatedThat's what makes it so fast.
ac compared with 8011n has four main technical evolution: wider bandwidth binding, more space flow, more advanced modulation technology and more flexible MIMO mechanism. A simple and efficient way to increase the speed of a radio transmission is to give it more frequency or bandwidth.
AC prefix usually means something like "communication" or "adaptive control". AC prefix explanation: In many cases, the AC prefix stands for"Communicate." For example, in the field of electronics, we often hear the concept of alternating current, which corresponds to direct current, indicating that the direction of the current changes periodically with time. In addition, AC may also mean communication in some other contexts, such as academic exchange, exchange conference, etc.
The ac prefix means all, together, accentuated, reinforced. An English word can be divided into three parts: prefix, stem and suffix. The part of a word that precedes the root is the prefix. A prefix can change the meaning of a word.
ac- == at; To, or said to strengthen the significance, accustom to habit, the account calculation, accounting, accredit trust, accompany company, acclaim cheers and applause, accomplish differ.
The prefix ac means close, so access means close. When used correctly, a root can often help us remember a list of words, and is far more reliable than rote memorization.
ac- == at; to. Disjunction tableTo strengthen the meaning, accustom to habit, account calculation, accounting, accredit trust, accompany, acclaim, acclaim, accomplish. Common English prefixes and suffixes: un-unhappy, unlike, unusual, unfriendly, unbalanced, uncover, unwrapped.
In English, ac- is a common prefix with diverse and rich meanings. Equivalent to at or to, it is used to express position or direction, and is often used to reinforce a word's meaning. For example, ac-custom means to make a habit, ac-count means to calculate or account, ac-credit means to trust, ac-company means to accompany, acclaim means to cheer or applaud, and accomplish means to accomplish.
