Radio Access Network (RAN) implementations in mobile networks have traditionally been vendor-specific and implemented with proprietary technology. They do follow the specifications laid out by 3GPP, ITU, IEEE, and other standards bodies, but RAN is complex (as governed by the laws of physics) and...
There’s never been a better time for distance learning! Join the EXFO team as we share our expertise in how to build healthier networks, faster.
We’ll discuss key 5G and fiber-optic technologies, present real-world use cases and share testing best practices. Register now, it’s the...
The rollout of 5G calls for radical changes in network architecture, technician knowledge and fiber deployed deeper into the network. To make sure those changes are successful and 5G transformations are done right the first time, operators and contractors need to revamp their testing...
According to Michael Gronovius, Customer Solutions Sale Director at Ericsson, the company’s decision to align its radio solutions with its fronthaul, backhaul, midhaul, microwave and router solutions is what sets Ericsson’s approach to a network transport apart. Ericsson transport is built by radio for...
Anritsu’s patented PIM over CPRI option is a new, non-intrusive method of measuring passive intermodulation (PIM) using live traffic over the Common Public Radio Interface (CPRI) link. It is set to change the dynamics of PIM detection by enabling users to test at ground...
Learn about the challenges of C-RAN, and best practices for testing
Â
Recent advancements in radio technology have allowed service providers to deploy LTE networks using a distributed baseband architecture. Radios are installed at the top of the tower, close to the antenna, and separated from...
To answer the need for more throughput at lower cost, wireless network providers have moved to using a remote radio head (RRH) where the radio equipment is connected to the baseband unit (BBU) by a fiber optic cable. This provides a new level of...

Marquis Dorais, fronthaul product line manager at EXFO, discusses how fiber helps mobile network operators build more efficient networks, and explains how operators can optimize their OPEX and improve the performance of next-generation mobile networks by adopting the right testing processes and overcoming the...
Cell site deployment is complex, costly and multi-staged. For RRH (Remote Radio Head) installation, there is typically an installation phase, and a completely separate turn-up phase when the BBUs (Baseband Units) are finally activated. However, a new process is emerging called BBU Emulation whereby...
Best practices help operators reduce opex and assure quality of experience
Tremendous cost pressure and an incredibly competitive carrier marketplace have created a dynamic in the telecom industry marked by a pressing need to combat churn by ensuring quality of experience while maximizing network investments...
As CPRI and OBSAI gain traction, stay competitive while cutting costs
To keep up with data-hungry customers, carriers are working to add capacity and flexibility to their networks. This trend has resulted in a movement to centralized Radio Access Network, which separates the radio into...
Learn how to pinpoint uplink interference while reducing tower climbs and saving money
Interference can make or break a cell site commissioning. From the macro tower layer to indoor small cell deployments, interference costs time and money while creating the potential for customer churn based...
Suddenly, on a Monday morning around 9:30 am, we started to get calls at the NOC of high dropped calls near a strip mall; this continued till 6 pm. Everything was working fine last week; we did not make any changes to the network,...
CPRI testing at the base station reduces truck rolls, tower climbs and OpEx
Carriers are increasingly turning to centralized Radio Access Network (C-RAN) architecture and CPRI (Common Public Radio Interface) to provide network flexibility, to be able to scale quickly, and to be able to...
With the rapid roll out of tower mounted radios and deployment of C-RAN network architectures, new installation and maintenance methods have to be developed to reduce installation and maintenance costs. The use of costly tower climbing crews needs to be minimized resulting in new...
The latest and greatest in enterprise small cells, DAS/RAN integration and carrier 5G outlook were all on display at the recent LTE North America show. RCR Wireless News Managing Editor Sean Kinney takes you inside.
On this episode of HetNet Happenings, Kinney takes a look...
DALLAS — It is becoming widely accepted that small cell networks are essential to cost-effectively bolster network capacity. At this year’s LTE North America conference, Amit Jain, VP of business development at SpiderCloud Wireless, spoke about the role virtualization will play in the densification of...
HetNet Happenings is brought to you by CommScope.
On this episode of HetNet Happenings, host Sean Kinney, managing editor for RCR Wireless News takes a look at how CPRI--common public radio interface--can be applied to digital DAS (distributed antenna system) deployments.

Kinney looks at an interview with...
In a distributed antenna system deployment, about half of the cost of installation – trade labor rather than material, labor and electronics – lies in the head-end, where the DAS host unit connects to mobile operator base stations. It pays to optimize the head-end...
AT&T's Paula Doublin likes to say that she is part of the "greatest business on Earth." As AVP of antenna solutions, DAS and small cells at AT&T, Doublin oversees in-building wireless projects throughout the United States. She says her job has given her a...
JDSU has added the ability to analyze radio frequency characteristics over the Common Public Radio Interface, or CPRI, specification for base stations. The company said it is the first in the industry to introduce integrated CPRI support on a base station analyzer, its CellAdvisor...
