5.1.1.1. Cellular Signal Strength References <br />The following table quantifies the quality of the signal based on the cellular signal strength <br />in dBm. <br />NOTE that all current FLO gateway models use 4G/LTE. 3G/HSPA+ is only used for legacy <br />gateways. <br />Excellent <br />Good <br />Fair <br />Poor <br />Deadzone <br />3G / <br />>-70 dBm <br />-71 to <br />-86 to <br />-101 to <br /><-110 dBm <br />HSPA+ <br />-85 dBm <br />-100 dBm <br />-109 dBm <br />4G / LTE <br />>-90 dBm <br />-91 dBm to <br />-106 dBm to <br />-111 dBm to <br /><-120 dBm <br />-105 dBm <br />-110 dBm <br />-119 dBm <br />5.1.1.2. Inadequate Cellular Signal on Site <br />If a site has an inadequate cellular signal, the communication gateway can be configured to <br />work with an existing Internet service through a LAN connection made via Ethernet or both <br />a master router and auxiliary communication gateways can be deployed onsite. <br />If the site requires any of these configurations, the appropriately configured <br />communication gateways must be selected at ordering and programmed for those <br />purposes before leaving our installations. <br />5.2. Gateway Layout Options <br />The charging stations' layout and configurations may impact the communication gateway <br />layout. <br />15 <br />
