[0062] It should be noted that the satellite communication module 300 is a hardware device used to implement satellite communication functions. It can enable devices to transmit data through the satellite network and is applicable to remote areas or special application scenarios where cellular network coverage is unavailable.

[0063] It should be understood that 5G modules support the latest fifth-generation mobile communication technology, providing higher data rates, lower latency and greater network capacity, and are applicable to application scenarios that require high-speed data transmission and low-latency communication, such as high-definition video transmission, autonomous driving and industrial automation, etc.; while 4G modules support the earlier fourth-generation mobile communication technology, although they are not as fast and have lower latency as 5G, they still have advantages in current network coverage and cost-effectiveness and are applicable to a wide range of IoT applications, including smart payment, vehicle-mounted systems and smart homes, etc.; currently, there are various 5G and 4G modules available in the market.

[0090] Furthermore, the first baseband processing unit 304 is further configured to generate a second digital baseband signal.

[0091] It should be noted that the first baseband processing unit 304 not only processes digital baseband signals but is also responsible for generating a second digital baseband signal; this involves signal encoding, modulation, or other digital signal processing tasks to prepare the signal for further conversion and transmission; for example, generating a digital signal containing voice, data, or image information through specific pins and transmitting this signal to the radio frequency chip; the effect is to digitally process and encode-modulate the information to be sent, prepare it for subsequent wireless transmission, and ensure that the information can be accurately transmitted in the satellite communication channel.

[0096] The first antenna unit 301 is further configured to receive the amplified baseband radio frequency signal and radiate the amplified baseband radio frequency signal in the form of electromagnetic waves in the direction of the satellite.

[0097] It should be understood that the first antenna unit 301 receives the amplified baseband radio frequency signal and radiates it in the form of electromagnetic waves towards the satellite direction; this requires the antenna to have appropriate gain and directivity to effectively send the signal to the satellite.

[0098] This embodiment provides a description of a portable Wi-Fi conversion device.
