Experts at an Iranian knowledge-based company succeeded in designing and producing a 4G cellular remote radio unit (RRU) which is used by the mobile operators to upgrade their 4G network infrastructure.
“The RRU product has been designed and produced by our company's specialists. This device, supporting various deployment and implementation scenarios, can fully meet the needs of the country's telecommunications network,” said Ali Akbar Tadayyon, the managing director of Farabin company.
“The 4G radio base station includes an RRU and a baseband system (BBU), and also has a management, operation and maintenance system that allows centralized management, configuration and software upgrades for operators,” he added.
Tadayyon explained that the RRU improves network coverage and capacity, specially in rural areas, adding, “This device is placed near the antenna and reduces costs by increasing signal quality and improving data transfer rates, as there is no longer a need to use low-loss cables to transmit radio signals.”
A Remote Radio Unit (RRU), commonly referred to as a Remote Radio Head (RRH), is a transceiver that you’ll find on wireless base stations. These transceivers connect wireless devices with wireless networks, making it possible to send and receive text messages, among other things.
RRUs are one of two primary units of a wireless base station. The RRU is the RF processing unit; it transmits and receives signals. You’ll typically find the RRU at the top of a base station, mounted near the antenna. RRUs can receive, transmit, filter and amplify RF signals.
