High Power UHF 380-400MHz Signal Booster for Public Safety Network Indoor and

ATNJ public safety solution solves the toughest emergency wireless communication challenges and delivers consistent in-building coverage across any type of structure - from high-rises and stadiums to underground transit hubs. Available in channel-selective or band-selective configurations to match your network architecture.

Built on P25 & TETRA - The Foundation of Modern Public Safety Networks

P25 (Project 25) and the analogous TETRA systems are the bedrock upon which modern Public Safety Networks (PSNs) are being built. These open standards ensure interoperability, security, and mission-critical reliability for first responders.

Rising frequency exhaustion, bandwidth congestion, and an increasing number of transmission sources have driven the need to allocate dedicated frequencies to PSNs. The choice of P25 and TETRA is dictated by:

• Seamless operation with existing analog equipment
• Expandable functionality - easy adoption of new technologies
• Higher load capacity - supporting more users and data traffic
• More complete coverage - eliminating dead zones inside complex buildings
• Superior RF propagation - critical for penetrating concrete, steel, and low-E glass

• Intelligent to guide the installation with LCD
• Real time display of signal strength
• Automatic dormancy when no user is making calls
• Automatic alarm when installation mistake occurs and provides corresponding solution
• Automatic adjustment of system gain to avoid repeater self-excitation
• Initiative reminding when the device is damaged
• Supports from 0.2 to 30MHz bandwidth adjustment (Customized), supports 5G bandwidth, 40MHz, 50MHz, 60MHz, 70MHz, 80MHz, 90MHz, 100MHz (Frequency Bandwidth Customized)
• WiFi Monitor+Control (Customized), NMS (network management system), Function Optional

Located in Guangming District Shenzhen, Shenzhen ATNJ Communication is a professional RF manufacturer mainly engaged in R&D, production, manufacturing, sales, and technical services with 16 years of experience.

The main products include Digital LTE/NR series repeater, SDR core board, Passive devices, Digital DAS system, and technical solutions for Public and Private (VHF, Tetra) network base station, wireless frequency modules. Meanwhile, we undertake OEM, ODM services and projects of various RF, wireless repeaters, multi-frequency DAS systems, remote network management center OAM, and equipment provision of indoor and outdoor signal coverage projects.

Nowadays, our digital repeaters not only reach 12 subbands simultaneously with local and remote control+monitor, but are also supplied to signal operators and communication integrators worldwide, providing signal coverage solutions for residential areas, office buildings, supermarkets, basements and rural areas.

More mature digital band-selective repeaters were successfully put into overseas mobile operator markets. Our product field is extending to Public Safety and Low altitude economic construction applications which include Public and Private Network Digital Multi-subband Repeater wireless signal repeater, Integrated Base Station, Civil countermeasure and phased array radar technology. Furthermore, Digital fiber multi-frequency, UHF, Tetra, VHF, Microwave frequency shift repeaters are realized. With the progress of science and technology, easier-to-use, more functional and intelligent RF products are being developed. We look forward to collaborating with you to create a brighter future together.
