The world of coal mining is a field of work that has a high risk. Open requires achieving production without compromising safety aspects. There are types of heavy equipment to support coal mining operations. One type of heavy equipment is a mining material pushing tool called a dozer. Dozers generally work in areas near cliffs that are prone to landslides, where these areas can be classified as dangerous areas. New technology is needed to increase the safety of dozer operators from the threat of danger when operating a dozer. Teleremote dozers are one method that can reduce the risk of accidents that can happen to dozer operators. Instead of operating the dozer from inside the cabin, the operator operates the dozer via a remote control device. There is an important aspect in operating a teleremote dozer, namely the need for a signal that will transmit data and commands from the remote control to the dozer unit operating in the field. Good and uninterrupted signal quality is the main key to good teleremote dozer operations with minimal risk. The wireless signal network system currently used by companies will enter its obsolete period. However, the old system was tough and not easily damaged. There are strategic options for supporting the signal network for teleremote dozer operations: maintaining the old network system, replacing it with a new one, or using the old and new systems in a hybrid manner. Because there will only be one strategy chosen, a decision must be made. The SWOT AHP method is used for decision making regarding the strategy to be taken. The results of the AHP SWOT will produce a strategy, which will become a benchmark for making subsequent alternatives. Determining alternative types of network systems to support teleremote dozer operations will use the AHP method. There are criteria and sub-criteria that appear based on SWOT, where the Strength criterion, with the Enhanced Capability sub-criterion being the strongest factor in the criteria according to respondents' choice was 46.4% and Global Priority was 28%. Alternative strategies that emerge from the AHP SWOT results will be used as a reference for determining next steps. Alternative strategies that emerge are maintaining the old communication network system, replacing a new type of network system, or using the old and new systems in a hybrid manner. AHP results for the best alternative strategy are replacing a new type of network system with a value of 57.6%. After the strategy is obtained, it will continue with the stage of determining the type of new system that will be used. There are several technical and commercial criteria and sub-criteria that will be used as weights to determine the 3 available alternatives: Small LTE, Private LTE, and Kinetic Mesh. The priority criteria for determining alternatives is redundancy with a Global Priority of 23.9%, and the alternative chosen is Kinetic Mesh with a weight of 66.8%.
