Last year, Apple introduced an attractive feature in the latest version of OS X and iOS systems: upgrade to Mac and iPad tablet computer system can answer the call to the same account number iPhone on the phone, so that users in the use of computer or tablet will not miss the mobile phone calls, and there is no need to leave the seat can go to iPhone answer the phone.
Last year, Apple introduced an attractive feature in the latest version of OS X and iOS systems: upgrade to Mac and iPad tablet computer system can answer the call to the same account number iPhone on the phone, so that users in the use of computer or tablet will not miss the mobile phone calls, and there is no need to leave the seat can go to iPhone answer the phone.
But it is very convenient and practical function in practical application has encountered a dilemma: with the binding of iPhone Mac or iPad usually in mobile phone rings after a few seconds to respond, more trouble is to use a device to answer the call, other devices will continue to ring a few seconds before the bell stopped. It is obviously not the original intention of the new technology to have an unpleasant delay in the device that should be synchronizing. So, why do you have this problem?
A large part of the responsibility comes down to the WiFi network. WiFi network technology has been unable to get rid of the problems of high delay, unstable signal and high power consumption from the beginning of its birth. As more and more devices use WiFi connections, the interference between devices is becoming more and more serious. In the above example, if the distance between mobile phones and computers and wireless routers is closer, the experience will be very good. If the distance is far away and there are obstacles and interference in the transmission of signals, the experience will not be satisfactory.
Of course, it is not a serious problem that the tablet is still ringing for a few seconds after the phone is connected to the phone. But the fact that we have to face a serious challenge: the existing network technology has been difficult to meet the requirements of the age of intelligent equipment. Imagine the following scene: housewives with soup to buy a new intelligent electric cooker, before boiling water back to the bedroom with the child; a mobile phone to suggest that the soup soon boiled, and housewives gracefully using a mobile phone to fire off a small. As a result, when she came back to the kitchen, she found out that a large amount of soup had been overflowing. There was a delay in sending and reminding the intelligent electric cooker, resulting in the failure of firepower to be adjusted in time.
A similar disaster may occur on all smart devices. In the future, all kinds of household appliances, lamps and lanterns and people's watches, glasses and other articles will be intelligentized, and the data transmission and communication between devices will be far more complex than today. The existing wireless network systems are struggling to cope with the needs of single digits. Facing dozens of devices intensive transmission needs, it is bound to be pressure mountain and even become the biggest bottleneck affecting user experience. If this problem is not solved, the age of smart home and smart wear is probably an empty talk.
The industry needs new technologies, specifications and products to make up for the shortcomings of existing wireless networks. New technologies need to do the following: more stable connection bandwidth, in response to the game, such as remote LAN video playback with high bandwidth applications; reduce the network delay, meet the needs of real-time communication between devices; flexible complex interference; convenient deployment and control; reducing power consumption. In view of the current technological trends, these requirements may not be met by a single standard. The more promising technology combination is the combination of +5G band WiFi network and Bluetooth 4.2 connection in electric power or twisted pair LAN. Fixed large household appliances use power network, mobile phones and tablet devices use 5G WiFi, wearable devices and small appliances use Bluetooth 4.2. Using a variety of network specifications can effectively reduce signal interference, reduce delay and improve the actual network bandwidth.
At the software level, the connection between different devices requires a new specification. There are many different ways of communication between different intelligent devices, and the experience is not good. The industry needs a unified, system level software standard for equipment interconnection. In the new standard, the device should handle the interconnected communication request from the bottom of the operating system to the high priority, and automatically select the most suitable transmission mode from various networks. In addition to connecting with routers, all kinds of devices should have the ability of direct connection between devices. Especially, the new standard should focus on the ease of use, allowing users to easily join or exit the home network, while ensuring the safety of the network.
At the product level, future wireless routers need not only stronger performance, but also both power, WiFi and Bluetooth connections. Smart appliances may integrate wireless signal expansion to facilitate network coverage. At the beginning of the design, all kinds of devices should consider the needs of mutual cooperation, maximize the use of network resources and automatically adjust their own network bands to reduce interference.
There are huge business opportunities behind these requirements: control the standards of the next generation LAN, which is equivalent to controlling the lifeblood of intelligent hardware devices. Who can provide users with a convenient and safe integration solution, who can take the lead in the smart home and smart wear war. Imagine: some manufacturers launched a smart Home Furnishing connected with the network package, without re wiring, as long as the router and the signal extender placed in throughout the room can meet the standards of automatic network; intelligent device boot will automatically apply to join the network, without the need to manually set the user; communication between devices almost no delay, signal stability, not there are at the beginning of this article the embarrassment; users do not have to worry about such as IP, set the security settings of such problems, etc.. The manufacturers that can provide such experience will naturally be popular, become the leader of the market, and lead the intelligent hardware industry to gain rich profits. We look forward to such a change as soon as possible, allowing consumers to make early use of a convenient, fast, safe and stable network to lay a solid foundation for the popularization of intelligent hardware.
