Repeater Lira DR-1000 V NEW Case

The Lira DR-1000 repeater will help organize uninterrupted communication in any conditions

Repeater Lira DR-1000 V NEW Case is a high-performance device. It is necessary to strengthen and relay the cellular signal in areas with poor coverage or no signal at all. It is ideal for use in remote areas, underground structures, shopping malls, office buildings and other places with limited cellular network access.

Repeater purpose 

The main function of the Lira DR-1000 V NEW Case repeater is to strengthen a weak cellular signal and relay it to a wider area. This allows cellular subscribers to make calls, send messages and use the mobile Internet even in places where the network signal is initially absent or very weak.

The repeater operates on the “receive-transmit” principle. It receives a weak signal from a cellular network base station and amplifies it to a sufficient level. This is necessary to ensure reliable coverage in the repeater coverage area. The amplified signal is then transmitted back to the network, providing uninterrupted communications for subscribers.

The Lira DR-1000 V NEW Case repeater has the following technical characteristics and features:

• Supports multiple communication standards. GSM 900/1800 MHz, UMTS 900/2100 MHz, LTE 800/900/1800/2100/2600 MHz
• High gain. up to 100 dB
• Wide operating frequency range. 890-915 MHz, 1710-1785 MHz, 1920-1980 MHz, 2110-2170 MHz
• Low noise figure. Less than 5 dB
• Automatic gain control. To maintain optimal signal level
• Overload protection. Prevents repeater damage when exposed to strong signals
• Easy installation: does not require special knowledge or equipment
• Compact and robust housing: protects the repeater from external influences

Benefits of use

• Improving call quality: Eliminates weak signal problems, providing stable and reliable coverage for subscribers.
• Coverage expansion: Increases the coverage area of the cellular network, allowing subscribers to stay connected even in remote or hard-to-reach places.
• Improved network performance: Optimizes the use of network resources, reducing the load on base stations and improving overall network performance.
• Increased throughput: Increases network capacity, allowing subscribers to use mobile Internet at higher speeds.
• Security improvements: Ensures uninterrupted communications for emergency services and other critical organizations in the event of network outages.

The Lira DR-1000 V NEW Case repeater finds application in a variety of areas, including:

• Remote areas. Improving connectivity in rural areas where cellular signal is weak or non-existent.
• Underground structures. Providing communications in basements, tunnels and other underground spaces.
• Shopping centers. Eliminating communication problems in large shopping complexes with thick walls and a large number of visitors.
• Office buildings. Improving the quality of communication on the upper floors and basements of office buildings.
• Industrial enterprises. Providing communications in production workshops and other industrial facilities with limited access to a cellular network signal.
• Emergency services. Improved communications for emergency services such as police, fire and ambulance in critical situations.

The Lira DR-1000 V NEW Case repeater is an indispensable solution for ensuring uninterrupted and reliable communication in areas with a weak or absent cellular network signal. Due to its high technical characteristics, wide operating frequency range and ease of installation, the repeater is ideal for use in various areas, including remote areas, underground structures, shopping centers, office buildings and industrial plants. With the Lira DR-1000 V NEW Case repeater, cellular subscribers can enjoy stable and reliable communications even in the most difficult conditions.
