Detailed Description
The present invention will be described in further detail below.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
Embodiment 1, a transmission efficiency improving system and method suitable for a high-density WIFI environment, the system may be installed at a server, such as a wireless router or a wireless AP, or may be installed at a client, such as a mobile phone, a laptop, a tablet computer, and the like. Specifically, the system and various functional modules in the following text are actually stored in the form of software codes in the driver of the server and/or the client, the technical scheme is not limited with respect to specific programming language types, and a software designer can directly select a mature programming language in the prior art.
And S01, identifying the transmitted packet. The first step is that when a certain sending packet is scheduled to be sent out from one end (client or server) through a certain channel, the sending packet identification module identifies the type of the sending packet. Three data types are defined in the WIFI protocol, namely a management packet, a control packet and a data packet. The data packets are formal data, and the management packets and the control packets are used for connection authentication of the devices, confirmation of the data packets, assistance, and the like. That is, in order to transfer data packets between WiFi devices through a channel, some management packets and control packets must be transmitted to assist. There are various ways to identify the transmitted packet, for example, there may be a data identifier in the transmitted packet, and the value of different data identifiers indicates the type of the transmitted packet, which is defined by the WIFI protocol, such as the common definition in the IEEE 802.11 standard.
And S02, accelerating. The step is the core step of the technical scheme. The WiFi protocol is a time-division half-duplex protocol. No matter how many devices are on a certain channel, only one device can transmit data at a certain time, and other devices cannot transmit data at the same time. In actual use, these management and control packets for assistance are often sent at the lowest rate (1 Mb/s for 2.4G band and 6M/s for 5.8G band). This means that as long as there is WiFi device transmitting these low-speed management packets and control packets, other devices on the same channel can only wait for these low-speed management packets and control packets to finish transmitting, and then can possibly preempt the channel right. Therefore, although the management packets and the control packets have a relatively small capacity, they take a long time to transmit. In a high-density environment, these frequent transmissions of management packets and control packets become one of the bottlenecks affecting the transmission performance. In the scheme, the transmission rate of the management packet and the control packet is increased in a high-density environment, the overall time ratio of the management packet to the control packet is reduced, and the overall WiFi performance of a certain fixed channel in the high-density environment can be improved.
WiFi device support rates are roughly divided into two categories: one is the base rate and one is the supported rate. The WiFi protocol frames selected for the base rate are sent out at the maximum power supported by WiFi, which ensures that the transmission area is larger, and ensures that the WiFi protocol frames can be received by other WiFi devices to the maximum extent. Although the rate-supported transmission is faster, control and management packets need to inform and coordinate other WiFi devices, and are more conservative at the base rate. 2.4G (bgn) with a base rate of 1Mb/s, 2Mb/s, 5.5 Mb/s, 11 Mb/s; these four speeds are also specified under the WIFI universal protocol, and in the 2.4G band, the speed-up module selects 11Mb/s to send the management packets and the control packets. The basic rate of the 5.8G band is 6Mb/s, 12Mb/s, 24 Mb/s; these three speeds are also specified under the WIFI universal protocol, and in the 5.8G band, the speed-up module selects 24Mb/s to send the management packets and the control packets.
And S03, a sending packet sending step, wherein the sending module sends the sending packet according to the set speed after the speed increasing module increases the speed.
In addition, the transmission efficiency improving system can only improve the sending speed, but cannot improve the receiving speed. That is, when the mobile phone and the router are in data communication, if the mobile phone is equipped with the transmission efficiency improving system, the management packet and the control packet sent from the mobile phone to the router can be accelerated, and the management packet and the control packet sent from the router to the mobile phone cannot be accelerated. Therefore, in actual use, the data transmission speed of the whole WIFI network can be better improved by installing the transmission efficiency improving system at the server side and the client side.
