According to the embodiment of the invention, the WIFI6 module is carried on the MTK platform for the first time, so that the strong combination effect is achieved, and the method is quicker and more convenient to surf the internet compared with other machines on the same platform.

Specifically, the MTK platform includes a Kernel space and a user space, where a Kernel space can execute any command and call all resources of the system; the User space can only execute simple operation, can not directly call system resources, and can only send instructions to the kernel through a system interface (also called system call).

Iferf is a network performance testing tool based on TCP/IP and UDP/IP, and can be used for measuring network bandwidth and network quality and providing statistical information such as network delay jitter, data packet loss rate, maximum transmission unit and the like. The network administrator can know and judge the network performance problem according to the information, thereby positioning the network bottleneck and solving the network fault.

The main functions of Iperf are described below.

(1) Aspects of TCP

2. And multithreading is supported, and multiple connections are supported between the client and the server.

3. The size of the MSS/MTU value is reported.

4. Supports TCP window value customization and can be buffered through sockets.

(2) UDP aspect

2. the network jitter value and the packet loss number can be tested;

3. supporting multicast testing;

4. the method supports multithreading, and supports multiple connections between the client and the server;

chariot consists of two parts: the control end Console and the remote end Endpoint can be installed on a common PC or a server, the control end is installed on a Windows operating system, and the Endpoint supports various mainstream operating systems.

The control end is the core part of the product, and a control interface (a command line mode can also be adopted), a test design interface, script selection and compilation, result display, report generation, an API (application programming interface) interface and the like are all provided by the control end. The Endpoint can be installed at a single terminal or a plurality of terminals according to the requirement of actual test, and is responsible for receiving instructions from the control terminal, completing the test and reporting the test data to the control terminal.

Chariot uses a built-in script to control remote ends to actively send packets to each other through a control end, and tests functions, pressure, performance and the like of equipment, wherein test results comprise throughput, time delay, jitter, packet loss, wrong packets and the like, and quantitative data can be obtained and detailed test reports can be provided, so that a user can actively master the performance condition of the equipment, timely find problems and take measures.

Chariot may emulate any application through various mechanisms. First, Chariot sends different data streams through built-in scripts, which can simulate the 125 applications that are now common, and the data streams are bidirectional and really interact with the protocol stack. Chariot supports various applications based on multiple data streams sent between endpoints, the delivery of which can be based on multiple protocols including TCP, UDP, RTP, SPX, IPX, and SNA, and IPv6 is also currently supported. Chariot also supports multiple advanced technologies such as Multicast, QoS, etc., and will remain synchronized at all times. In addition, scripts that can be used by Chariot can be generated by the toolkit Application Scanner when new or special applications arise. Chariot allows the script to be customized, and various parameters of the data stream, such as the starting interval of the start, the sending window, the size of the receiving window, the size of the sending file, the sending rate, the type of the sent bit stream, the using port, etc., can be changed, and these parameters can be not only a typical value specified by the user, but also random values conforming to the average distribution, normal distribution, poisson distribution or exponential distribution between the maximum and minimum values, so as to truly simulate various specific data streams in the network and comprehensively test the performance of the network or the network device in a complex network environment.

One feature of modern networks is the distributed development, which may involve many nodes in the process of testing the network performance. By adopting Chariot software, the whole network can be tested by directly tapping the mouse for a few times at the central control end. The remote end of the Chariot can be directly downloaded on a NetIQ company website or remotely installed on a required node machine through a central control end, the Chariot can support 10000 remote cooperative tests at most, and remote software can be installed randomly according to requirements and can be awakened during testing.

The first MTK processor adopts MT6205, MT6217, MT6218, MT6219, MT6226, MT6227 and MT6228 baseband chips, and the chips all adopt ARM7 cores.

The MT6305 and the MT6305B are power management chips;

MT6129 is RF chip;

the PA with RF3146(7 x 7mm), RF3146D (dual frequency) and RF3166(6 x 6mm) as RFMD has higher integration level and low cost.

Specifically, SDIO (Secure Digital Input and Output card) is a peripheral interface.

SDIO defines a peripheral interface on the SD standard. SDIO has two main types of applications-removable and non-removable. The Mobile device is used as an expansion device of Palm and Windows Mobile to add Bluetooth, camera, GPS and 802.11b functions. Non-removable devices follow the same electrical standard, but are not required to comply with physical standards. Some handsets include 802.11 chips connected to the CPU through the SDIO.

One important difference between SDIO and SD card specifications is the addition of low speed standards. The SDIO card requires only SPI and 1-bit SD transmission mode. The target application of the low speed card is to support low speed I/O capability with minimal hardware overhead. The low speed card supports applications like modems, barcode scanners and GPS receivers. For a "combination" card (memory + SDIO), full speed and 4-bit operation are both mandatory for the memory and SDIO portions of the card.

The specific format is shown in fig. 3.

Specifically, 802.11ax, also known as a High-Efficiency Wireless-HEW, increases system capacity through a series of system characteristics and multiple mechanisms, improves the working mode of the Wi-Fi network through better uniform coverage and reduction of air interface medium congestion, and enables users to obtain optimal experience; especially in a dense user environment, a consistent and reliable data throughput is provided for more users, with the goal of increasing the average throughput of the users by at least a factor of 4. That is, Wi-Fi networks based on 802.11ax imply unprecedented high capacity and high efficiency.

The 802.11ax standard introduces a number of major changes in the physical layer. However, it is still compatible with 802.11a/b/g/n and ac devices in the downward direction. As such, the 802.11ax STA can transmit and receive data with legacy STAs, and legacy clients can also demodulate and decode the 802.11ax packet header (although not the entire 802.11ax packet) and poll during 802.11ax STA transmissions. 802.11ax is an 802.11 Wireless Local Area Network (WLAN) communication standard that transmits over the 2.4G and 5G frequency bands.

One of the primary goals of the 802.11ax standard is to increase the wireless speed of individual network clients by a factor of 4. The 802.11ax standard may bring Wi-Fi connection speeds up to 10.53Gbps over the 5GHz band.

The 802.11ax standard will be able to improve Wi-Fi performance in a multi-user environment (e.g., public space hotspots), mainly by improving spectral efficiency, better managing crosstalk, and enhancing underlying protocols (e.g., medium access control data communications). New standards should make public Wi-Fi hotspots faster and more stable.

The 802.11ax standard also uses Orthogonal Frequency Division Multiple Access (OFDMA) to boost the amount of data that a router can transmit. Like Orthogonal Frequency Division Multiplexing (OFDM) techniques, OFDMA encodes data on multiple subcarriers-i.e., packs more data in the same spatial region. "multiple access" by OFDMA describes a way to allocate subsets of these subcarrier frequencies to individual users.

In addition to the development of new standards, IEEE is developing two supplementary protocols for wireless networks to address other needs. The IEEE 802.11ad standard uses an unlicensed 60GHz band to build fast short-range networks with peak rates up to 7 Gbps.

However, there are two major drawbacks to data transmission at 60GHz, one is the poor wall penetration at short wavelengths and the other is the absorption of electromagnetic energy at 60GHz by oxygen molecules.
