LTE networks provide the high-speed data transmission necessary for simultaneous voice and data services, with theoretical download speeds reaching 100 Mbps and upload speeds of 50 Mbps under optimal conditions. The actual performance varies based on network congestion, signal strength, and environmental factors, but even in suboptimal conditions, 4G networks typically deliver sufficient bandwidth for high-quality voice communications and moderate internet usage.
Voice over LTE (VoLTE) technology constitutes a critical component in modern 4G FWT systems. Unlike earlier cellular technologies that handled voice and data through separate channels, VoLTE transmits voice calls as data packets over the LTE network. This approach provides several distinct advantages: superior voice quality through HD Voice codecs, faster call connection times (typically 2-3 seconds compared to 7-8 seconds with 3G), and simultaneous voice and data transmission. The implementation of VoLTE in fixed cellular terminal 4g devices ensures crystal-clear audio quality that often surpasses traditional landline performance, with wider frequency ranges capturing more natural voice characteristics.
The SIM card compatibility and activation process for 4G FWTs follows standardized procedures similar to mobile phones but with some important distinctions. Most FWTs accept standard-sized SIM cards from cellular providers, though business-grade devices may support multiple SIM cards for redundancy or load balancing. The activation process typically involves:
- Inserting an activated SIM card into the terminal device
- Connecting power and peripheral devices (telephones, computers, etc.)
- Performing automatic network registration and configuration
- Testing basic functionality including inbound/outbound calls
Hong Kong's telecommunications market offers specialized FWT plans from major providers like CSL, SmarTone, and China Mobile Hong Kong, with data allowances specifically tailored for voice-centric usage. These plans typically include unlimited local calling with monthly fees ranging from HKD 98 to HKD 198, representing significant savings compared to traditional business landline services that often exceed HKD 300 monthly.
The technological architecture of a typical fixed gsm terminal includes several key components: a 4G LTE modem for cellular connectivity, a DSP (Digital Signal Processor) for voice compression and echo cancellation, an RJ11 port for analog telephone connection, and sometimes additional features like Ethernet routing and Wi-Fi access point capabilities. Advanced models may incorporate failover mechanisms that automatically switch to backup 3G networks when 4G signals become unstable, ensuring continuous service availability.
