BREAKING NEWS
The ULAK 4.5G Base Station is a fully integrated LTE Advanced radio access network (RAN) solution developed with a high domestic engineering content ratio. It is designed not only as a commercial telecom product but also as a strategic national infrastructure asset aimed at ensuring technological sovereignty in communication systems.
Operational Role and Mission
ULAK’s primary mission is to deliver high-speed LTE broadband, voice over LTE (VoLTE), IP-based multimedia services, and secure communication capabilities for both civilian and critical public services.
Operational deployment scenarios include:
Thus, ULAK is positioned as both a commercial telecom solution and a national resilience enabler.
Doctrine and Concept of Use
The system operates within three main strategic layers:
Unlike conventional foreign-supplied base stations, ULAK’s software control and core intellectual property are domestically managed, which strengthens cybersecurity and strategic independence.
System Architecture
The ULAK 4.5G system consists of three main components:
Remote Radio Unit (RRU)
The RRU handles RF signal generation, amplification, and antenna transmission. It supports multiple frequency bands and enables 2x2 and 4x4 MIMO configurations. The system delivers up to 4x40W RF output power, allowing extended coverage and enhanced signal penetration.
Baseband Unit (BBU)
The BBU hosts LTE Layer 1–2–3 protocol stacks and manages critical functions such as:
It supports 4x4 MIMO with 20 MHz LTE bandwidth and provides sector capacity ranging from 300 Mbps to 900 Mbps, depending on configuration.
The system supports up to 18 CPRI interfaces, enabling flexible multi-RRU deployments.
Network Integration
ULAK connects to the Evolved Packet Core (EPC) through standard S1 interfaces. It is compatible with existing operator backhaul infrastructures and integrates seamlessly with IP-based transport networks and OSS systems.
Survivability and Security Approach
One of ULAK’s primary advantages is its domestically controlled software stack. This provides:
