Presently owing to the limited range of the commercially off shelf mobile handsets (UE), base stations/ gNodeB are deployed at regular intervals to provide connectivity to the users. The deployment of base stations at regular intervals increases the manpower required for manning the eqpt thereby increasing the fingerprint in the Tactical Battle Area (TBA) and increasing administrative load. The proposed mobile handsets (UE) will provide enhanced ranges of military mobile network coverage thereby reducing the need for deployment of base stations thereby reducing security risks. MILGRAD/ JSS-55555 compliant dual band (Band n3 & n28) 5G mobile handset (UE) for military applications having a power output of 500mW or better with a high gain antenna of 3 dBi or better, internal MIMO 2T4R or better, physical PTT, detachable battery capable of providing standby time of 48 hours or better and talk time of 12 hours or better in QPSK modulation shall be utilized in the Tactical Communication System along the Western Borders, Network in a Box (NIB) and MINT. The mobile handset (UE) shall enhance the operational efficiency of the system by providing enhanced ranges thereby requiring deployment of lesser number of base stations.
