Description

Technical Field

[0001] The present invention belongs to the field of network communication technology, and specifically relates to a system and method for reducing the 4G networking cost of a low-voltage distributed power supply. Background Art

[0002] As operators accelerate the withdrawal of 2 / 3G networks, the industry market needs new cellular IoT technology connections and has chosen Cat4 modules. The speed of Cat4 modules is as high as 150Mbps, which meets the high-speed requirements of most IoT connections; however, high speed means high cost, and the cost of deploying Cat4 modules is expensive. For segmented IoT scenarios such as low-voltage distributed photovoltaics, not all links require 100M speeds. At this time, the price of Cat4 modules is unaffordable, which becomes an obstacle to the large-scale commercial use of low-voltage distributed photovoltaic 4G networks. Like Cat4 modules, Cat1 modules are based on mature LTE networks. Operators do not need to upgrade the network, but only need to perform simple parameter configuration to allow Cat1 modules to access the network.

[0003] However, existing directional IoT cards cannot be assigned fixed IP addresses, only dynamic IP addresses. In some application scenarios that require fixed IP addresses, networking failures often occur due to technical limitations.

[0004] The present invention provides a system and method for reducing the 4G networking cost of low-voltage distributed power sources to solve the above-mentioned technical problems. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a system and method for reducing the cost of 4G networking of low-voltage distributed power supplies, which is used to solve the problem that when selecting Cat1 modules and directional Internet of Things cards for 4G networking of low-voltage distributed power supplies in the prior art, the directional Internet of Things cards cannot allocate fixed IP addresses, so it is difficult to realize 4G networking in some application scenarios that require fixed IP addresses. Although the existing solution requires the use of fixed IP Internet of Things cards for 4G networking, this situation can be avoided. However, the network service fee of the fixed IP Internet of Things cards is more expensive than that of the directional Internet of Things cards, resulting in the technical problems of low stability and high cost of 4G networking of low-voltage distributed power supplies.
