The future of human x811 on a notebook, but also my productivity tool, but unfortunately that brother was too heavy 4.2kg more than I was plugged in two hard drives into, far more than 4.2kg, back and forth every day is no business. And can only wait for two hours, go out to use more than two hours to bring a huge charger, really unbearable. From last year's apple education discount wanted to buy a notebook, and also think that after all, poor. Has been entangled MacBook air and MacBook pro, because the poor want to buy the MacBook air, but later out of the new MacBook moment grass, then became a tangle of new macbook and MacBook pro. Daily brush apple dynamic, waiting for a release conference, still no new notebook, but waited for a message, the new pro to join the touch bar, but the battery because of the die, was exposed to low yield, workmanship It's not good to wait for a problem, just wait. In advance of the fight, and yesterday in Tianjin Henglong apple start, send solo wireless, I chose the dark space gray, personally feel more atmospheric, not out of the box. Come up with what you want. You can comment below to support Tianjin's face-to-face contact and Shunfeng in the field. (My brother and I said that I came up with the idea of ​​solo. He suggested that I should buy golden ones better, but if this thing does not work, I will choose a dark space ash. You can use it for yourself I bought the configuration and price of pro: Solo2 wireless You asked me why I didn't buy a link from Jingdong but two East and West links. I didn't buy more than 1,000 things in a certain East, but I'm faster. Ok, I'm East Dog! Future human x811 and MacBook pro boxes are bigger than others' boxes! Macbook is not important, pro is important Small mark is love. Open the box is pro Line line, book, nothing A front view Just bought the notebook did not under what app (the following app is cracked) After buying a computer does not dare to take the fear of scratching the notebook is not good-looking, with a hurry to sell shells! As a result, my brother hummed aside and I have been buying it for almost a year now. I have been streaking. Can you see if the shell is not quite good? It is indeed! This kind of computer is not in a hurry to protect! Written in the end, although the category is out of the box drying, but I am certainly not the first sun pro, nor will it be the last one. Write about the performance of it, before buying tangled buy new MacBook or macbook pro, Apple's little brother know that I am a programmer after life recommended I buy pro, said new macbook performance is not good, before my friend gave me poisoned milk A moment, okay, okay, you guys are all right about the macbook pro. As for why not buy 512g or 1t hard disk, I am more like the 950pro cut the price to buy a 2t himself put on. After all, performance did not have to say! It is still possible to use 256 now. Programmer programmer program, right. Fibonacci Series The simplest recursive method for 50 items The recorded video screenshots on the mobile phone are really different from x811, so if it is new macbook, is it even worse? It's like this, thank you! What is a wireless AC controller? What does it do? Ac Controller,Gigabit Wlan Controller,Enterprise Ac Gateway,Wireless Ap Controller Shenzhen MovingComm Technology Co., Ltd. , https://www.movingcommtech.com
Wireless AC controller is a kind of network device, such as the AC100/150 of Fengrunda, which can be used to centrally control and manage wireless aps. It is the core of a wireless network and is responsible for managing all wireless aps in the wireless network. AP management includes: delivering configuration, modifying related configuration parameters, RF intelligent management, and access security control.
Why use a wireless controller, and what exactly does it do?
In fact, the role of the wireless controller is to play a gateway function between the WLAN and the Internet (on the router), and the data from different access points are aggregated and accessed to the Internet. The role of an access point (AP) is to complete wireless access, and it can control user access through network flags.
The role of wireless controllers
1, Flexible networking mode and excellent scalability
The AP does not need to be directly connected to the AC, so that the AP can be deployed in any place that needs to be covered through the network, such as you deploy an AP in each employee's home, and then connect to the wireless controller inside the enterprise through the VPN, you can expand the wireless network of the enterprise to the family of each enterprise member.
2, intelligent RF management functions, automatic deployment and fault recovery
Through the dedicated RF management module, we can initially estimate the AP deployment according to the user's architectural design drawing, and can calculate the average bandwidth of the wireless terminal, the coverage between AP and AP in the actual debugging process.
3. Centralized network management
All the configuration of the wireless network can be completed by configuring the wireless controller. For example, enable, manage, and maintain all AP devices and mobile terminals, including all functions such as radio wave spectrum, wireless security, access authentication, mobile roaming, and access users.
4, powerful roaming function support
The wireless controller uses AP as the boundary combined with fast RF management system, which greatly reduces the connection time between wireless client and AP, and thus realizes the function of fast roaming.
5. Load balancing
AP and wireless controller systems can distribute wireless users or terminals to nearby aps within the coverage area of an AP, ensuring the number of each wireless terminal or the sum of AP bandwidth transmission or the upper limit of each wireless terminal bandwidth.
6, wireless terminal positioning, rapid fault location and intrusion detection
Wireless controllers can track and locate the location of wireless terminals, such as wirelessly connected computers, PDAs and Wi-Fi mobile phones.
7, powerful access and security policy control
At present, the wireless system supports authentication of 802.1, WEB authentication, MAC, SSID, VPN, etc., and supports various encryption modes such as WEP, WPA, WPA-PSK, WPA2, etc., and all configurations can be configured globally through the wireless controller.
8, Qos support
AP and wireless switching systems can limit the maximum bandwidth of a user's wireless connection within each user's privileges. For different IP services, the system can also define different QoS queues through the wireless switch module. For example, for wireless voice applications, SIP and RTP protocols can be set in the high queue, while common applications such as http and ftp can be set in the low queue.
The wireless controller AC is more advanced than the AP, plays the role of manager in the wireless network, and the wireless controller AC also acts as a client to complete a series of functions in the wired network (such as authentication, authentication, etc.). However, wireless controller AC is not a WLAN device specified in the 802.11 protocol family, but as a supplement to the protocol in specific applications, and its price far exceeds that of ordinary access point (AP) devices.
In small-scale wireless networks that use only a few aps, it is not economical to use expensive wireless controller AC equipment. However, if the number of wireless aps is large, more than 20 can be used AC controller.
