Next Generation DMR Technology 

The HR652 is the next generation of compact DMR repeaters designed to expand radio range with consistent, reliable, and seamless voice and data communications. It is fully compliant with the DMR standard with TDMA digital technology, providing two simultaneous voice channels, doubling voice channel capacity. 

Key Features

Extended Range 

The HR652 features industry-leading RX sensitivity and 25 Watts output power, increasing the effective communication range of radios throughout a campus, industrial site, city, or high-rise building.

Optional Battery Power

The HR652 features an optional battery for portable applications and for battery backup power. The 12.5Ah large-capacity battery can provide up to 4 hours when transmitting at 25W or 9 hours at 10 watts (assuming a 50-50 duty cycle). Fast charging technology enables the battery to be fully charged in just 3.5 hours with the optional AC/DC power adapter 100W fast charger.

Analog & Digital Auto Switching

The HR652 can operate in analog, DMR, or dynamic mixed digital/analog modes.  When using dynamic mixed mode the repeater automatically switches between analog and digital calls, and provides a smooth analog to digital migration. When operating in dynamic mixed mode, the repeater will listen for both analog and digital signals and will automatically repeat either DMR or analog signals without the need for any reconfiguration or reprograming. 

IP Site Connect (Software License Required)

IP Connect enables linking multiple HR652 repeaters via Ethernet LAN/WAN networks, third-party IP networks, VPNs, and microwave.  It provides a cost-effective and flexible way to expand coverage to multiple locations, or to provide supplemental coverage for a campus, or large building to ensure radio network coverage throughout the entire facility. IP-Connect also provides cross-connect functionality to link radios using different UHF/VHF frequency bands.

SFR-Single-Frequency Repeater Mode (optional software license)

The HR652 has the ability to function as a conventional analog or digital DMR repeater. Additionally, it can also function as a DMR single-frequency repeater (SFR). Conventional repeaters require two frequencies, one for receiving, and one for transmitting. 

A DMR single-frequency repeater SFR leverages DMR technology, which splits a single channel into two time slots. An SFR will use one time slot to receive and the other to transmit. 

Instead of receiving on one frequency and transmitting on another like a conventional repeater, a DMR single-frequency repeater receives on one time slot and transmits on the other. The result is a DMR repeater which operates using only a single frequency.   

Benefits of SFR

• Single Antenna operation. Because traditional repeaters utilize two frequencies, they require either;  (1) two adequately spaced antennas (one for transmit and one for receive) or (2) a duplexer which filters the receive frequency from the transmit frequency. However, since an SFR uses only one frequency there is no need for a duplexer or two antennas. 

• Simplicity and Compactness. Once again because only a single frequency is used there is no need for two antennas or a duplexer. As such utilizing SFR mode may increase both the compactness and the simplicity of your system. 
  

• Simplified FCC Licensing. Simplified FCC Licensing. Since only one frequency is being used an SFR can typically be licensed as a mobile radio rather then a repeater. 

• Reduced Cost. SFRs can reduce system costs by eliminating the need for a duplexer and by simplifying the FCC licensing process. 
  

Single-Frequency Repeater Mode (SFR) Considerations

• Limited Cross Compatibility. Unlike conventional analog and DMR repeater modes, SFR is a proprietary mode of operation, which may not be compatible across all brands. As such, it is recommended that systems utilizing SFR mode use radios from the same brand as the SFR. In this case, Rangeland recommends only using Hytera radios with the HR652 if it's configured for SFR use. If the HR652 is being used as a conventional DMR or analog repeater, radio brands can be mixed without issue. 

• No Analog/Digital Auto Switching. The analog/digital auto switching functionality will not be available when the repeater is configured as an SFR.
  

• DMR Mode Only. SFR mode is only compatible with DMR and will not repeat analog signals.  
  

• Single Talk Path. Conventional DMR repeaters are able to leverage DMR time slots to provide two talk paths which can be used simultaneously. In other words, a conventional DMR repeater, which uses two frequencies, can support two conversations by different talk groups at the same time. On the other hand, SFRs can only support a single talk path. You can still have multiple talk groups, however, only one person would be able to transmit at any given time across all of the talk groups. This would likely only be an issue for organizations that need several talk groups and also have a large number of users.
