Alfa Tube-E4G

The Alfa Tube-E4G is a professional-grade outdoor 4G/LTE modem designed to provide stable, high-speed internet access in environments where traditional wired connectivity is unavailable or unreliable. With extensive support for LTE FDD, LTE TDD, WCDMA, and GSM frequency bands, the device ensures broad compatibility with mobile network operators worldwide. This makes it an ideal solution for global deployments, whether in urban, rural, or remote locations where consistent connectivity is essential. Delivering LTE speeds of up to 150 Mbps download and 50 Mbps upload, the Tube-E4G is capable of handling bandwidth-intensive applications such as HD video streaming, remote monitoring, cloud-based systems, and IoT deployments.

Even in areas where LTE coverage is weak or inconsistent, the device automatically switches to 3G or 2G networks, maintaining a continuous data connection without manual intervention. The versatility of the Tube-E4G makes it suitable for numerous use cases, including rural broadband access, construction sites, agricultural environments, surveillance systems, transportation, marine installations, and backup connectivity for business networks. Its ability to operate independently of fixed infrastructure allows users to deploy internet access quickly and efficiently wherever it is needed.

Engineered for durability and long-term outdoor use, the Alfa Tube-E4G features a robust IP66-rated enclosure, offering full protection against dust ingress and strong resistance to rain, moisture, and harsh environmental conditions. The rugged design makes the device suitable for installation in exposed locations such as poles, rooftops, walls, towers, and other outdoor structures without requiring additional protective housing. The device is equipped with high-gain omnidirectional antenna, which enhances signal reception and stability, especially in areas with weak cellular coverage. This ensures consistent connectivity even in challenging environments. For additional flexibility, the Tube-E4G is equipped with an N-type female connector, allowing users to attach an external antenna if higher gain or directional coverage is required.

The device is designed to operate reliably across a wide temperature range of -40°C to +80°C, making it suitable for deployment in extreme climates, from cold northern regions to hot industrial zones. Despite its industrial-grade construction, the Tube-E4G maintains a compact and lightweight form factor (185 × 47 mm, 135 g), simplifying transportation and installation. Its cylindrical design also facilitates mounting on poles or masts, making it a practical choice for outdoor network setups. Overall, the Tube-E4G combines durability, flexibility, and performance, making it an excellent solution for professional, industrial, and commercial applications that demand long-term reliability and minimal maintenance.

The Alfa Tube-E4G is designed for straightforward integration into modern network infrastructures through its RJ45 Ethernet port with PoE (Power over Ethernet) support. This allows both data transmission and power delivery over a single Ethernet cable, significantly simplifying installation and reducing the need for additional power wiring. This is especially beneficial for outdoor deployments where running separate power lines can be complex or impractical. In a typical setup, the device is connected via a standard Ethernet cable (Cat5e or Cat6) to a PoE injector or PoE-enabled switch located indoors. The injector or switch supplies power to the device while simultaneously providing network connectivity.

The use of Ethernet also allows for cable lengths of up to 100 meters, making it ideal for installations where the modem needs to be placed far from the main network equipment. This flexibility is particularly valuable in scenarios such as perimeter surveillance, industrial sites, farms, or large properties where network infrastructure is distributed over a wide area. The Tube-E4G integrates seamlessly with routers, firewalls, and other networking equipment, acting as a reliable cellular WAN connection. By combining Ethernet connectivity with PoE functionality, the Tube-E4G offers a clean, efficient, and professional solution for delivering outdoor cellular connectivity in a wide range of applications.
