Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, an embodiment of the present invention provides a WiFi system, which includes a baseband processor 10, a WiFi chipset 30, and a radio frequency transceiver 20 with an LTE-U interface; the baseband processor 10 is respectively connected to the WiFi chipset 30 and the radio frequency transceiver 20 in a communication manner; the baseband processor 10 processes the WiFi frequency band signal received by the radio frequency transceiver 20 into a readable signal of the WiFi system, and processes the signal to be transmitted by the radio frequency transceiver 20 into a WiFi frequency band signal that can be transmitted by the radio frequency transceiver 20.
The radio frequency transceiver 20 with the LTE-U interface uses an unlicensed frequency band including WiFi frequency bands of 2.4G and 5GHz, so that a WiFi system can also use the radio frequency transceiver 20 to transmit data. The baseband processor 10 is an important component of a mobile phone, a router, and other devices, and is equivalent to a protocol processor, and is responsible for data processing and storage, and the main components include units such as a Digital Signal Processor (DSP), a Microcontroller (MCU), and a memory (SRAM, Flash), and the main functions include baseband encoding/decoding, voice encoding, and voice encoding. Because the rf transceiver 20 cannot be directly used in the WiFi system, the baseband processor 10 is pre-configured with processing software for processing, so as to process the WiFi frequency band signal received by the rf transceiver 20 into a readable signal of the WiFi system, and process the signal to be transmitted by the rf transceiver 20 into a WiFi frequency band signal that can be transmitted by the rf transceiver 20. In this embodiment, the preset software processes the WiFi signal to be transmitted by the rf transceiver 20 and the WiFi frequency band signal received by the rf transceiver 20 by using a MAC (media authentication Codes) algorithm. The MAC algorithm refers to a Hash function with a secret key: the Hash value of the message is controlled by a secret key K known only to the two communicating parties, in which case the Hash value is called MAC. The radio frequency transceiver 20 has a corresponding antenna 40, and the WiFi chipset 30 is also connected with the matched antenna 40.
In this embodiment, the WiFi chipset 30 includes a 2.4G frequency band interface and a 5G frequency band interface, and in other embodiments, an interface of one frequency band of the two interfaces may be optionally selected.
In an embodiment, the baseband processor 10 controls the rf transceiver 20 and the WiFi chipset 30 to transmit or receive WiFi signals in the same frequency band, so as to implement multi-antenna MIMO communication. The MIMO is an abbreviation of Multiple Input Multiple Output (MIMO), and refers to that wireless network signals are synchronously transmitted and received through Multiple antennas 40 to increase data transmission rate. In this embodiment, performing multi-antenna MIMO communication includes two cases:
firstly, simulating a 2.4G WiFi interface by using an LTE-U interface of a radio frequency transceiver 20, and simultaneously using WiFi of a 2.4G frequency band by using the LTE-U interface and a primary ecological interface of a WiFi chipset 30;
secondly, the LTE-U interface of the radio frequency transceiver 20 is used to simulate a 5G WiFi interface, and the LTE-U interface and the original WiFi interface of the WiFi chipset 30 simultaneously use WiFi of a 5G frequency band.
Further, the baseband processor 10 obtains the communication quality of the current 2.4G frequency band interface and the current 5G frequency band interface, selects the frequency band interface with good communication quality to receive or send signals, and controls the radio frequency transceiver 20 to receive or send signals in the same frequency band as the frequency band interface with good communication quality. That is, it is determined which of the 2.4G frequency band network and the 5G frequency band network is better in the current network environment, and the selected network is used, for example, if the signal transmission quality of the 2.4G frequency band network in the current network environment is higher than that of the 5G frequency band network, both the WiFi chipset 30 and the radio frequency transceiver 20 select to use the 2.4G signal of the 2.4G frequency band network to transmit and receive data. The quality of the frequency band signal communication can be judged by utilizing the signal to noise ratio of common signals.
In another embodiment, the baseband processor 10 controls the rf transceiver 20 and the WiFi chipset 30 to transmit or receive WiFi signals with different frequency bands, so as to implement multi-antenna 40DBS communication. The DBS, that is, Dual-band simultaneous communications, realizes multi-channel communication by combining Dual-frequency concurrence of 2.4GHz and 5GHz frequency bands. Two cases are included in implementing multi-antenna 40DBS communication:
firstly, an LTE-U interface of a radio frequency transceiver 20 is used for simulating a 2.4G WiFi interface, and a primary WiFi chip of a WiFi chipset 30 uses a 5G interface, so that 2.4G and 5G double-frequency synchronous generation is realized, and further, a DBS communication function is realized;
secondly, the LTE-U interface of the radio frequency transceiver 20 is used to simulate a WiFi interface of 5G, and the original WiFi chip of the WiFi chipset 30 uses an interface of 2.4G, so as to implement synchronous generation of dual frequencies of 2.4G and 5G, thereby implementing DBS function.
Further, the baseband processor 10 obtains the communication quality of the current 2.4G frequency band interface and the current 5G frequency band interface, and selects the frequency band interface with good communication quality to receive or send signals; and controlling the radio frequency transceiver 20 to receive or transmit signals of another frequency band opposite to the frequency band interface with good communication quality. That is, it is determined which signal of the 2.4G band network and the 5G band network is better in the current network environment, and the selected network is used, for example, the signal transmission quality of the 2.4G band network in the current network environment is higher than that of the 5G band network, the WiFi chipset 30 selects the 2.4G band, and the radio frequency transceiver 20 selects the 5G band network to transmit and receive data. The quality of the frequency band signal communication can be judged by utilizing the signal to noise ratio of common signals.
In another embodiment, the baseband processor 10 controls the rf transceiver 20 to transmit or receive WiFi signals with the same frequency band and different channels from the WiFi chipset 30, so as to implement duplex communication. The duplex communication means that if data is received by the rf transceiver 20, the data is transmitted through the WiFi chipset 30, and if data is received by the WiFi chipset 30, the data is transmitted through the rf transceiver 20, and the data can be transmitted by the WiFi system at the same time as the data is received. In this embodiment, when performing duplex communication, four cases are included:
firstly, the LTE-U interface that uses radio frequency generator simulates 2.4G's wiFi interface, and the native wiFi interface of LTE-U interface and wiFi chipset 30 uses the wiFi of 2.4G frequency channel simultaneously, and the wiFi of two 2.4G frequency channels uses different channels, and one only carries out data reception, and one only carries out data transmission, and this kind of method can divide into two subclasses again like this: an LTE-U simulated interface is used for sending WiFi signals of a 2.4G frequency band, and an original ecological 2.4G interface of a WiFi chipset 30 is used for receiving data; or an LTE-U analog interface is used to receive WiFi signals of a 2.4G frequency band, and the original ecological 2.4G interface of the WiFi chipset 30 is used to transmit data;
secondly, the LTE-U interface of the radio frequency generator is used to simulate a 5G WiFi interface, the LTE-U interface and the original WiFi interface of the WiFi chipset 30 use WiFi of a 5G frequency band at the same time, two WiFi of the 5G frequency band use different channels, one WiFi only receives data, and the other WiFi only transmits data, so the method can be divided into two categories: transmitting a WiFi signal of a 5G frequency band by using an LTE-U simulated interface, and receiving data by using an original ecological 5G interface of a WiFi chipset 30; or an LTE-U analog interface is used to receive WiFi signals of a 5G frequency band, and the original 5G interface of the WiFi chipset 30 is used to transmit data;
thirdly, an LTE-U interface of a radio frequency generator is used for simulating a 2.4G WiFi interface, and an original ecological WiFi chip of a WiFi chipset 30 uses a 5G interface, so that 2.4G and 5G double-frequency synchronous generation is realized, and the DBS function is further realized; the WiFi of the 2.4G frequency band can be sent by using an LTE-U simulated interface, and the WiFi of the 5G frequency band can be received by using an original 5G interface; or an LTE-U simulated interface is used for receiving WiFi of a 2.4G frequency band, and an original 5G interface is used for sending WiFi of a 5G frequency band;
fourthly, an LTE-U interface of the radio frequency generator is used for simulating a 5G WiFi interface, and an original ecological WiFi chip of the WiFi chipset 30 uses a 2.4G interface, so that 2.4G and 5G double-frequency synchronous generation is realized, and the DBS function is further realized; the WiFi of a 5G frequency band can be sent by using an LTE-U simulated interface, and the WiFi of a 2.4G frequency band can be received by using an original 2.4G interface; or an LTE-U simulated interface is used for receiving WiFi of a 5G frequency band, and an original 2.4G interface is used for sending WiFi of a 2.4G frequency band.
Further, the baseband processor 10 obtains the communication quality of the current 2.4G frequency band interface and the current 5G frequency band interface, and selects a frequency band interface with good communication quality to receive or transmit signals; the baseband processor 10 obtains the current 2.4G frequency band signal and the current 5G frequency band signal through the radio frequency generator, and controls the radio frequency generator to select the frequency band signal with good communication quality to receive or send signals. The duplex communication function is realized by only needing software to realize selection on a UI interface, the four modes can be automatically selected by a user, a simple algorithm can be also performed, a data optimal mode is adopted by default, and the like.
In this embodiment, the baseband processor 10 obtains the number of access points accessing the WiFi system through the WiFi chipset 30 and the radio frequency transceiver 20, calculates the maximum data throughput required by the current network according to the number of the access points, and turns off the radio frequency transceiver 20 if the maximum data throughput is less than or equal to the limit throughput of the WiFi chipset 30. This may save energy overhead of the radio frequency transceiver 20. The number of the access points may be calculated by receiving the respective signaling of the access points connected to the rf transceiver 20 and the WiFi chipset 30, for example, the baseband processor 10 may obtain the number of the access points by sending the respective received signaling to the baseband processor 10.
In this embodiment, the baseband processor 10 obtains the number of access points accessing the WiFi system through the WiFi chipset 30 and the radio frequency transceiver 20, and equally allocates the access points to be connected with the WiFi chipset 30 and the radio frequency transceiver 20. Load balancing may be performed efficiently by evenly assigning access points to the WiFi chipset 30 and the radio frequency transceiver 20.
In a specific embodiment, in the WiFi system setup mobile phone, an application program for the WiFi system is installed in the mobile phone, and a user can actively control a working mode of the WiFi system according to a use environment, such as implementing multi-antenna 40MIMO communication, multi-antenna 40DBS communication or duplex communication, and then the WiFi system automatically selects a frequency band signal with good signal quality for communication through the baseband processor 10.
Compared with the multi-path WiFi system with the multi-WiFi chip set 30, the WiFi system provided by the embodiment of the invention has the advantages that the radio frequency transceiver 20 with the LTE-U interface is used for simulating one WiFi transceiver, and then the signal of the WiFi frequency band is received or sent, so that the transmission of the WiFi signal is realized, the cost is reduced, and the throughput and the sensitivity of the WiFi system can be improved.
