| Incredible audio quality There is no doubt that digital walkie-talkies can get a clearer picture of voice calls. The walkie-talkie can provide you with excellent digital audio performance in the coverage area, and its unique features can help employees speak clearly and clearly wherever they are. Intelligent audio can automatically adjust the volume of the radio, compensation background noise, so the workers don't have to adjust the volume of the radio can be avoid in noisy environment, missed call or disturb others when quiet area. Enhanced background noise suppression helps to filter out unwanted external noise - from the noise emitted by heavy equipment to the roar of the engine. Oversize and coverage Employees work hard every day - hauling heavy loads, repairing roads, providing security, responding to customer demands, or restoring power after a storm. Interconnect IP base station by using the Internet to expand coverage to create a wide area network, will expand the coverage of a single base station or geographically dispersed base station connected together, which helps greatly improve customer service and increase productivity. Capacity Plus (cluster extension) single base station cluster solution, which can extend the communication Capacity to more than 1000 users without adding new frequencies. Linked Capacity Plus combines the expansion Capacity of Capacity Plus with the wide coverage of IP base station interconnection to provide multi-base cluster solutions with high Capacity, wide coverage and efficient economic performance. Therefore, whether you want to use a single base station or a multi-base station, MSTAR can meet your business and budget needs. over! |
