Abstract
Description
Technical Field
[0001] The invention relates to the technical field of communication, and in particular to a HPLC-based point-to-multipoint network transmission system. Background Art
[0002] With the rapid development of wireless communication technology in recent years, narrowband wide area network technology, such as LORA and NB-IoT, has been widely used. However, in complex environments, such as underground environments with multiple layers of enclosed spaces such as basements, or environments with strong signal shielding, the wireless signal is only weak or even non-existent. Many terminal communication devices in such environments will have the following problems: 1) Similar wireless signals are extremely weak or even not covered at all. Even terminal devices with strong penetrating signals such as LORA and NB-IoT cannot transmit data to the ground or other places; 2) When the terminal device data cannot be transmitted wirelessly, it can only be processed manually by professional maintenance staff, which requires high manpower investment for the entire project, higher maintenance costs, and low efficiency in implementation due to large workload; 3) If the public network signal is enhanced through operators, it will cause high construction costs, and require a large number of facility modifications, destroying the original design and related facilities and possible hidden dangers, and the final effect is not very obvious for the signal increase.
