In the face of a messy line, are you still looking for your speaker cable? For so many years, the source of the sound source - the speaker - has been used in people's minds, although it has also been proposed to wirelessly connect these devices. However, every company wants to set its own standards, which has led to the current goal of wireless connectivity.
This article refers to the address: http://
In fact, we already have wireless hardware devices, WiFi source devices, powerful wireless 802.11/a/b/g/n networks, and speakers that can be wireless at any time. It's not good to have hardware, we still need a standard, a standard that is enough to make these devices seamlessly interconnected - Airplay. What we call Airplay is not the player name in Baidu search, but the wireless internet protocol proposed by Apple.
On today's Apple official website, although we can't find any official explanation for Airplay, we can see from the illustrations and introductions that Airplay can transfer video, audio and pictures on devices such as iPhone, iPad or iPod touch to On the third-party authentication device, the transmitted carrier is WiFi, which is essentially different from Bluetooth wireless.
Create a home wireless Apple Airplay technology entry
I believe that for many fruit powders, although they own the iPhone, they don't know much about Airplay technology. On the one hand, Apple does not focus on promoting Airplay related concepts. On the other hand, third-party devices that support Airplay tend to sell at higher prices. But this does not affect people's expectations for Airplay, after all, it is currently the most complete home wireless interconnection technology.
Starting today, we will deeply analyze the technical characteristics of Apple Airplay, the skills of its formation and its advantages and disadvantages. Before these, let's start with what Apple Airplay is for everyone, and what it can do for us. If you want to make your home cable disappear, take a look at Airplay technology.
â— How Airplay works
Mobile phones, computers, routers and Airplay speakers, all have in common that they support WiFi carriers, but the WiFi signal itself is not enough. We also need to add Airplay protocol to let these devices know what they are transmitting. Airplay is the "language" between devices and devices!
WiFi bandwidth is several times that of Bluetooth, and it has inherent advantages in hardware performance. At the same time, in terms of transmission distance, WiFi is also the most widely distributed and stable carrier in the IT field. So from the working principle, Airplay has reached a higher standard in the industry.

â— What can Airplay do for us?
If you think that Airplay can only be used to listen to music, it is a big mistake. Airplay can not only transfer audio files, but also transfer files such as videos and photos to AppleTV and printers, all of which are identified by the Airplay protocol.

Practical Apple Airplay
1.Airplay achieves audio wireless
There are many solutions for pure point-to-point audio, such as Bluetooth, wireless 2.4G, and so on. But what Airplay implements is the interconnection between any device under a LAN. In other words, there are 10 devices that have a WiFi network and support the Airplay protocol. Your mobile device can be connected to any Airplay speaker at any time without the need for temporary one-to-one pairing.
2.Airplay realizes video wireless
The Airplay mirroring function can be used to map the screen of a mobile device to a high-definition TV. This is similar to the current wireless video technology, but the difference is that video and audio use the same protocol standard, which is truly multi-purpose.
3.Airplay wireless printing
This is quite well understood, and many vendors already have this feature. Airplay joins wireless printing to supplement its functional side. After all, with enough technical support, there is nothing wrong with one more function.
Single out of each function, there are many products can be achieved, video wireless, audio wireless and print wireless, but the three functions are integrated into one device, under one protocol, no need to add equipment, this is Airplay's take us The biggest convenience. Let's not say that Airplay has any shortcomings, but this kind of thinking is a lot of manufacturers for many years, and many organizations want to reach the ultimate goal.
â— What are the elements that make up Airplay?
1. Apple Airplay certified third party equipment
Airplay has strict rules on hardware. First, it must be Apple's original equipment or Apple-certified third-party equipment. For example, Android phones cannot be added to it. Apple's certification is both metamorphosis and convenience, so that manufacturers love and hate. With Airplay certification, the problem of compatibility between products is fundamentally avoided, and the problem of the old problem is solved.

2. A powerful wireless router
The wireless router is designed to provide a LAN environment. In theory, any router that conforms to the 802.11/a/b/g/n specification can be used. However, here we strongly recommend that users choose high-performance and stable wireless routing devices. Because the audio and video transmitted by Airplay requires a lot of bandwidth, ordinary routers may not be able to eat under high load.
In addition, compared with wireless 2.4G, we recommend wireless 5.8G router to avoid interference under wireless 2.4G frequency, providing a pure space for Airplay. Speaking of this, perhaps only Apple routers meet the requirements, this is indeed the case, their own equipment must be the perfect support for Airplay. Regarding whether other routers will affect Airplay, we will test it for you in the next article.

3. Apple's official device or PC with built-in iTunes
If you want to use Airplay, of course you have to have an iPhone or something, otherwise you will not talk. Of course, it doesn't matter if you don't have an iPhone or an iPad. There is always a computer with iTunes installed. With these you can build your own Airplay environment.
Written at the end:
After the above introduction, I believe that everyone has a preliminary understanding of Apple Airplay, we introduce so many today, in the next few articles, we will practice Airplay's formation method for everyone, and compare the airplay effect of Airplay. Step by step to teach you how to set up your own Airplay wireless home system, in fact, it is not difficult to build a wireless home.
Aluminum core Solar Cable is a photovoltaic circuit using aluminum as a conductive material. It is widely used in solar power generation systems to transport the electricity generated by solar panels.
Compared with traditional copper solar cable, aluminum solar cable has some obvious advantages, the most important of which is low cost.
1. Low price: Aluminum is a common metal, and its price is cheaper than that of copper. Therefore, the use of aluminum solar cable can reduce the cost of the system and make the entire photovoltaic power generation project more economical.
2. Lightweight: Aluminum has a lower density and is lighter than copper. The aluminum core optical cable can reduce the weight of the cable and facilitate installation and maintenance.
3. Strong corrosion resistance: Aluminum has good corrosion resistance and can maintain a long service life under harsh environmental conditions. This makes the aluminum solar cable more reliable for outdoor use.
4. Excellent conductivity: although the conductivity of copper is higher than that of aluminum, the aluminum solar cable can make up for the shortcomings of the low conductivity of aluminum to a certain extent by optimizing the design and process and ensure the efficiency and stability of power transmission.
It should be noted that there are also some limitations and precautions for aluminum solar cable. Due to the low conductivity of aluminum, the resistance of the aluminum solar cable will be relatively high, so it is necessary to choose the wire diameter and length reasonably when designing and installing to ensure the efficiency of power transmission. In addition, aluminum is prone to electrochemical reactions when it comes into contact with copper, so corresponding measures need to be taken when connecting aluminum solar cable and other components, such as using special connectors or coating protective layers.
In general, aluminum solar cable with its low cost, corrosion resistance, light and other advantages, has been widely used in solar power generation systems, and brings economic and reliability benefits to photovoltaic power generation projects.
