Electronic enthusiasts eight o'clock: April 14 news, Microsoft officially confirmed that Microsoft will hold an important Windows conference in New York City on May 2.
The amount of information in the invitation is very small. The only clue is the label "#MicrosoftEDU", indicating that the conference should focus on the topic of education.
From all the rumors that have been collected so far, and Microsoft's own initiative to infer the theme of education to the education, it is likely that this conference will not publish consumer products such as Surface Phone, or the next generation Surface Pro, Surface Book 2 Also not enough time to catch up with the appearance in early May.
Microsoft is likely to expose Windows 10 Cloud at this event, a lightweight system similar to Chrome OS that runs only UWP applications, and is used to fulfill the last wish of Windows RT. And Lenovo's new Surface news that was leaked from the supply chain, Microsoft is also likely to release a cheap version of Surface for students and educational institutions. It may abandon the splicing screen and switch to a traditional clamshell screen, which is consistent with the statement that “Surface changed design and returned to the clam traditionâ€.
Not long ago, Surface Pro 5 has quietly passed the national 3C certification. The information shows that Surface Pro 5 will continue to be manufactured by Mingshuo Computer (Suzhou) Co., Ltd. The power adapter specifications are exactly the same as Surface Pro 4, and the specifications are still 12- 15V, 1.6-2.58A.
The specific configuration is impossible to see in 3C certification. According to previous rumors, the Surface Pro 5 will be equipped with a 4K Ultra HD screen, Intel Kaby Lake processor, USB type-c/Thunderbolt 3 interface, and a magnetic charging stylus.
Since Microsoft recently announced that Windows 10 will support the ARM architecture, it is not excluded that Surface Pro 5 has plans to introduce ARM processor versions.
If Surface Pro 5 doesn't appear at this conference, then Microsoft must be making a big move, and Surface Pro 5 will have even more surprises.
Based on the current exposure news, Microsoft will not have much surprise in this release. A Surface Book notebook with lower price and more traditional design will be the biggest highlight of this conference. Perhaps Microsoft will also announce some information about the National Surface version of the Surface Studio machine.
As for the Surface Pro 5 and Surface Book 2 that everyone is waiting for, they need to wait patiently.

What is a wireless AC controller? What does it do?
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.
