Radio Shack

Traditional walkie-talkie systems have limited signal, while mobile phone communication is too fragmented. The innovation of the G258 lies in its access to the global mobile public network through a single SIM card, upgrading internal hotel communication into a stable and independent "dedicated wireless communication network." Whether employees are in the lobby, underground parking, high-rise guest rooms, or garden pool, as long as there is mobile network coverage, they can make instant group calls. The concierge can notify the front desk to prepare for check-in with a single click when a guest arrives; housekeeping can immediately contact engineering for support if a maintenance request is needed. This public network-based Radio Shack architecture breaks down the physical limitations of building structure and distance, making information transmission as direct and efficient as broadcasting on the same channel, tightly weaving scattered service nodes into a network.
