In fact, it is simple to create a hotspot, first get to the WiFi service, then configure the hotspot name, password and so on, and then open it through reflection OK.Let's look at the code implementation for creating hotspots:This section is to turn on the WLAN hotspot and can specify its hotspot name and password.After the sub-branch, this section of the program can turn on Wi-Fi and automatically turn off WiFi.Package Com.tel.lajoin.wifi.hotspot;imp

What is the first step to start the IOT project? Of course it is not hardware, but the connection between hardware and hardware! Even if there are various communication protocols that do not have good connection methods, it is absolutely impossible. If there is no screen on the peripherals and no keyboard, how can I enter the password and select the network? Yes, this is the most important solution for the WiFi module. To solve this connection problem, lexin added the smartconfig function to its

Why 802.11ac will kill the 5 GHz Wi-Fi band I took the opportunity during a recent briefing call with Qualcomm atheros (QCA) about its new 802.11ac devices to dig into some of the technical details behind 802.11ac. I'm gglad I did, because I learned a fewThings about the new higher-speed wireless standard that shoshould be more widely known. As you may know, 802.11ac is5 GHz onlyStandard. The reason for this is that 11ac needs to use lots of 20 MHz

How to make mobile downloads fly together with LTE and Wi-Fi With the rapid popularization of 4G terminals, LTE seems to be the fastest-transmitting mobile network technology. However, with the gradual rise of 4 k hd videos, how can we further break through the transmission speed in mobile networks? Based on the current network resource configuration in Beijing, the theoretical peak rate of the downlink network is about 80 Mbps, And the uplink peak

New Wi-Fi standard HaLow announcement: Bluetooth with low power consumption and high power consumption Recently, the Wi-Fi Alliance has passed a new standard, namely the expansion of the 802.11ah standard, which is called "HaLow ". As named by myself, HaLow focuses on low-power and low-power devices. The operator has set his sights on the currently evolving IoT, including smart home. Currently, smart h

In win10, how does one set Wi-Fi hotspots ?, Set wifi hotspots in win10 When no Wi-Fi router or Wi-Fi router fails, you can use Windows 10 as a Wi-Fi hotspot for iPhone, Android mobile phone, or other mobile devices, that is, allow Windows 10 computers to share their Ethernet or wireless Internet connections with othe

As we will discuss today, the old wireless routers can be converted to access points (APS), which can help increase the area of use for Wi-Fi. In addition, they can even help improve the performance of the 802.11n standard connected to your network. The wireless router and access point are different. First, you need to know the difference and connection between the wireless router and the access point. First, the wireless router contains an AP. Theref

The title is a bit around. In short, when you are in a Wi-Fi environment, but the desktop computer does not have a wireless network card, you cannot access the Internet wirelessly. At this time, you can use the Android mobile phone to connect to WIFI first, then the computer connects to the mobile phone through USB cable, and wireless Internet access through the mobile phone. Note: although it was tested in Ubuntu, this method is also feasible in Wind

The conditional judgment statement in the shell is an upgrade to the previous "conditional test statement in the shell", meaning that the preceding test statement serves the IF~THEN~FI statement for the current judgment statement. We're still rolling it out in the form of attention points and code implementations: 1) The basic IF-THEN-FI statement can be used to judge the basic single-layer branching struc

If your Skype or Second Life application is frequently disconnected, or when someone starts a World of Warcraft game, your iTunes Transfer Stream becomes congested, consider it, how to improve these problems without buying a new device. In the past few years, most of the wireless routers sold have QoS functions, but you may still want to update the firmware of the router to solve the problem. Let's take a Linksys router as an example. We can make some changes through the configuration program. F

Wi-Fi Alliance announces 802.11ah HaLow technology connection standards The Wi-Fi Alliance has developed industry standards for IEEE 802.11ah frequencies. The standard name is HaLow. The HaLow standard operates at a frequency lower than 1 GHz and provides a longer communication range and lower power, tailored to requirements for long-distance, low-power applications such as smart home, digital healthcare
