Why we need the SFR single frequency repeater for our communication ?

Technical Advantages: SFR repeaters, also known as Digital Mobile Radio (DMR) repeaters, allow two or more DMR radios to communicate bidirectionally over a greater distance. By receiving signals from the transmitting radio, amplifying them, and retransmitting at a higher power and/or different frequency, they extend the communication range. DMR technology uses Time Division Multiple Access (TDMA) to allow two conversations on the same frequency at the same time, effectively doubling the capacity of a given channel compared to analog systems, making DMR repeaters more efficient than analog repeaters.

Extended Communication Range: Repeaters significantly enhance the communication range and capability of walkie-talkies, allowing communication beyond line-of-sight distances and across broader geographical areas.

Development of IP Repeaters: With the proliferation of the Internet, IP repeaters have emerged, transmitting voice signals via IP networks to achieve global network interconnectivity, greatly expanding the communication capabilities of repeaters.

Wide Range of Applications: SFR repeaters have broad applications in various fields such as logistics, heavy industry, property management, tourism, and government and public safety sectors, all of which require long-distance wireless communication for dispatch and security.

Market Demand: As the demand for high-speed broadband continues to grow, SFR repeaters, as a more advanced technology, can provide faster and more stable network services, meeting market demands.

Efficiency and Reliability: SFR repeaters, through mobile networking, can automatically act as communication relays, achieving communication coverage in remote areas, underground parking lots, inside buildings, tunnels, and other places that traditional methods cannot cover, operating reliably and stably.

Support for Instant Positioning: SFR repeaters support instant positioning during calls, which is convenient for mutual search and also facilitates command and dispatch at management levels.

We would like to share you the below advantages which help you to save costs and enhance efficiency on radio communication.

---Frequency Resource Conservation: SFR only requires one frequency to achieve signal reception and forwarding, significantly saving frequency resources compared to traditional communication methods that need two frequencies.

--Cost Savings: As SFR does not require a duplexer, it can significantly reduce equipment costs, thereby lowering the overall construction cost of the communication system.

--Reduced Restrictions: SFR is not limited by the frequency bandwidth of duplexers, allowing for the selection of frequency points within the 150MHz/350MHz/400MHz bands, making communication deployment more flexible.

--Rapid Deployment: SFR stations are designed as integrated and compact units, making them easy to carry and quickly deploy, suitable for scenarios where it is inconvenient to set up base stations or for temporary tasks and on-site temporary communication.

--Ease of Use: With adaptive solutions, users do not need to manually switch between relay and non-relay communication environments, avoiding human operational errors.

--Broad Coverage: Through mobile networking, any vehicle-mounted radio, or individual backpack radio that arrives on site can immediately take on the role of communication coverage, achieving coverage in remote areas, underground parking lots, buildings, tunnels, and other places that traditional methods cannot cover.

--Reliable and Stable Operation: The maintenance workload of SFR communication networks is minimal, making it very suitable for use by non-profit government special departments. Its excellent survivability ensures the communication network's resilience even in the event of natural disasters.

--Instant Positioning During Calls: Supports instant positioning during calls, which is convenient for mutual searches and also facilitates command and dispatch at management levels.
