Absolute Analysis today introduces SkyRAN, a product that will make it possible for wireless service providers to monitor RF conditions remotely using the CPRI link, which will reduce RF interference debug time by up to 50% or more.

One of the most difficult and costly tasks for telecom operators is to debug uplink interference problems that can affect the Quality of Service (QoS) of a cell network. This problem has been exacerbated by the “Internet Everywhere” movement, which has caused the number of antennas and remote radio nodes in a network to increase exponentially. Unfortunately, monitoring systems that carriers currently use do not monitor the RF signal because it was traditionally analog into the eNodeB.

With the proliferation of remote radio head units using the CPRI link, the RF data is now available in the digital domain. Operators can now use SkyRAN to monitor this data remotely, as opposed to having to send technicians to gather this data at every problem site. SkyRAN interfaces to the CPRI link directly and sends the data back to the Network Operating Center (NOC) or regional monitoring centers. SkyRAN processes the RF data in real-time, and reports KPIs such as RSSI power levers, PIM detection, and many others.

“This solution revolutionizes the entire RF field testing and debugging industry,” says Dennis Murphy, CEO of Absolute Analysis. “The ability to remotely monitor RF conditions and send this data to technicians before dispatch will significantly reduce time-to-resolution for RF performance issues.”

The SkyRAN product includes a comprehensive set of features not found in any other product.

  •     Up to 96 ports can be monitored through an expandable chassis: The base unit allows 24 ports of monitoring and can be scaled by connecting multiple chassis.
  •     RF monitoring software has a flexible interface: Our flexible software interface can connect to existing software backhaul monitoring systems from various vendors.
  •     Full recording and alarming capabilities: Alarms can be set up to record events based on detection of RF events such as PIM or high RSSI.
  •     Real-time processing mode so full RF debug can be analyzed remotely: A technician can remotely get access to the RF power spectrum, to aid in analysis before making a trip to the location.
  •     Support for all network vendors: All major network manufacturers are supported, as well as any vendor compliant to the CPRI specification 6.0.

The base unit is housed in a 2U sized rackmount chassis.

The SkyRAN product will be available for order in Q2, 2016. For more information, please call our sales department at (805)376-6048.
