Multi-Radio Access Node (MRAN)

Multi-Radio Access Node (MRAN)

Indoor and Outdoor RF Signal Distribution System

Tecore’s Multi-Radio Access Node (MRAN) unit has been designed to provide a high power multi-band RF signal distribution system supporting 2G, 3G, 4G, and WiFi technologies simultaneously for both indoor and outdoor wireless applications. The MRAN amplifies the low power RF source signals, providing 50 dBm of transmit power in the downlink for transmission for each active frequency band. The uplink RF path is also amplified over an optical link back to each of the radio receivers. Both the downlink and uplink RF paths of the MRAN utilize coaxial cable and multiband antenna(s).

The MRAN includes six (6) high power broadband amplifiers providing up to 100 watts of transmit power in each of the six different frequency bands encompassing multiple technologies with a simplified user interface for OAM control. The MRAN OAM capabilities include the configuration and control for each of the high powered amplifiers (HPAs) as well as MRAN status and alarm screens. The MRAN supports two standard modes of operation, the first being an integrated Distributed Antenna System (DAS) mode of operation, which allows for direct connection of 3rd party base stations and repeaters. The second mode of operation offers a standalone Multi-technology RAN providing 2G GERAN, 3G UTRAN, and/or 4G EUTRAN from a single MRAN unit.

In the DAS mode of operation, a standard DAS primary HUB configuration is used to interface to the RF signal sources. The output of the DAS HUB is then fed over fiber to the low power Optical Radio Unit (ORU) integrated within the MRAN for high power amplification and distribution of the RF signals.

For the Multi-technology RAN mode of operation, the MRAN is integrated with Tecore’s CoreCell-R Radio Shelf. The MRAN CoreCell-R Radio Shelf allows for up to nine (9) low power Software Defined Radios (SDRs) to be deployed within each radio shelf and connected for high power RF distribution by the MRAN. The SDRs may be individually configured to support any frequency band and technology supported by the MRAN.

Tecore has incorporated over 23 years of experience in scalable wireless systems into the design of the MRAN unit. It leverages Tecore’s patented iCore portfolio of 3GPP compliant Software Defined Core networking elements and Software Defined Radio access networking elements. The MRAN with its robust capability and cost-effectiveness enables a broad range of wireless applications and may be customized to support customer specific requirements.
