Heavy Reading Disaggregation Survey Report Part 3

We have looked at plans for disaggregation and implementing functional splits in Heavy Reading’s survey of operators. In this post, we want to look at issues that affect TCO and operations.  Operators were asked to rank their top factors motivating your organization to adopt disaggregated networking solutions. Faster innovation and flexibility in adopting the latest

5G Evolution

5G transport will require a new router at the cell site. There are two main drivers. First will be the increase in the amount of bandwidth needed as cell sites expand and more radios are added. With the change to eCPRI, fronthaul gateways will no longer be required. Second, the router must be able to

Heavy Reading Disaggregation Survey Report Part 2

Previously, we looked at some of the data in Heavy Reading’s survey of network operators’ plans for disaggregation conducted in December 2020. Respondents had to work for a verifiable network operator and be involved in network planning and/or purchasing network equipment. There were 82 qualified participants that were counted in the results. Volta was pleased

Arrows converging on target

Convergence in the New Service Edge, Part 3

We started our series, Convergence in the New Service Edge, with a discussion on how 4G and 5G will have to coexist in the same transport network. In Part 2, we discussed how that transport network will support fixed as well as wireless traffic. 5G services are different. In this installment, we want to take

Convergence in the New Service Edge, Part 2

We started our series, Convergence in the New Service Edge, with a discussion on how 4G and 5G will have to coexist in the same transport network. Convergence goes beyond wireless. Many operators offer both fixed and mobile services. However, wireline and wireless access services have typically been served by completely different aggregation and core

Convergence in the New Service Edge: Part 1

Convergence, the integration of wireline and wireless technologies into a single network infrastructure, gets a lot of attention for good reason. Operators need to reduce costs to maintain profitability in the face of increasing traffic and declining price per bit. There are significant economies of scale in both CapEx and OpEx by consolidating onto a

Hard vs. Soft Network Slicing: What’s the Difference (Part 3)

In the previous two posts of these series, we first introduced network slicing in the context of 5G cellular networks, as a way to fulfill the heterogeneous requirements of diverse types of applications by determining how network resources are assigned to different types of application traffic. We then saw there are two mechanisms in 5G

Hard vs. Soft Network Slicing: What’s the Difference (Part 2)

In the previous blog post, we introduced network slicing in the context of 5G cellular networks as a way to fulfill the heterogeneous requirements of diverse types of applications by determining how network resources are assigned to application traffic. We saw that network slicing needs to be available across all components of the 5G cellular
