  • Application of TDMA in wifi: IPQ6010+QCN9024 realizes frequency multiplexing

    WIFI technology needs more breakthroughs and technology updates, and more and more projects require different wifi functions. Let's take a look at the role of TDMA in wifi today.

    TDMA, short for Time Division Multiple Access, is a digital communication technology used to divide a frequency into multiple time segments and transmit different data in each time segment.

    In a TDMA system, time is divided into continuous time frames (time frame), and each time frame is further divided into multiple time slots (time slot). Each time slot is used to transmit data of one user. Different users transmit data in different time slots, thereby realizing frequency multiplexing.

    A TDMA system usually consists of the following components:

    Base Station: Receives signals from different users and transmits them to the network.

    Controller: Control the allocation of time slots to ensure that each user sends and receives data in the correct time slot.

    terminal: A device that receives and sends data, such as a cell phone, modem, etc.

    The TDMA system has the following advantages:

    Efficiency: Allow multiple users to share the same frequency, improving spectrum utilization.

    Flexibility: Different time slots can be allocated according to the needs of different users.

    Reliability: When the data in a time slot is damaged, it will only affect the users of this time slot, and will not affect the data transmission of other users.

    The role of TDMA in wifi

    TDMA technology is widely used in mobile communication systems, such as GSM, TD-SCDMA and so on.

    In WiFi, TDMA can be used as one of the methods to realize frequency reuse. Specifically, when multiple devices in a WiFi network need to share the same channel, TDMA can be used to allocate time segments so that different devices can transmit data in different time segments.

    In a TDMA WiFi network, time is divided into multiple time slots, and each time slot is assigned to a different device for data transmission. Only in the time slot allocated by the device, data transmission can be performed, avoiding the situation that multiple devices occupy the channel at the same time. This increases the efficiency of the WiFi network and reduces the occurrence of collisions and interference.

    It should be noted that frequency reuse techniques used by different WiFi standards may be different. For example, 802.11a and 802.11n use OFDM (Orthogonal Frequency Division Multiplexing) technology, while 802.11e uses a modified TDMA technology called HCCA (Hybrid Coordinated Access) technology.

    TDMA technology can be used in routers for frequency reuse in wireless local area networks (WLANs) to improve network efficiency and capacity. In routers with IPQ6010 and IPQ4019 chipsets, TDMA technology is widely used in the implementation of 802.11ax (Wi-Fi 6).

    In the 802.11ax standard, OFDMA (Orthogonal Frequency Division Multiple Access) and MU-MIMO (Multi-User Multiple-Input Multiple-Output) technologies are used, which can help improve the throughput and capacity of the network. TDMA technology is used to divide time so that multiple devices can transmit data on the same frequency band, thus avoiding conflicts and interference between devices.

    IPQ6010 and IPQ4019 chipsets are high-performance router chipsets with powerful computing and network processing capabilities. They support the 802.11ax standard and can use TDMA technology to optimize the performance and capacity of the network to provide better user experience and quality of service. In addition, they also support other wireless technologies, such as Bluetooth, ZigBee, etc., to provide more functions and application scenarios.
