Even though UScellular plans to sell off big chunks of its spectrum and subscribers to T-Mobile, that's not stopping the regional wireless carrier from pursuing its fixed wireless access (FWA) ambitions — even if that means going head to head with T-Mobile in some regions.
In fact, UScellular is working with Tarana Wireless to increase its FWA capacity in West Plains, Missouri, a town where the demand for FWA is high. So high that the carrier has been getting such good uptake of its fixed wireless that it was about to run out of capacity on its mobile network.
As a solution, the operator decided to tap CBRS General Authorized Access (GAA) spectrum and use Tarana’s technology to add more capacity. UScellular equipped three of its existing towers in the area with Tarana gear.
Where before, UScellular had to stop selling its fixed wireless broadband product in West Plains, its salespeople have now resumed selling the product to more customers.
Mike Irizarry, executive vice president and CTO at UScellular, explained the evolution of the company’s FWA business. He said that UScellular — similar to T-Mobile and Verizon — has been taking advantage of the unused capacity on its 3GPP mobile network.
“When we launched a few years back, it was on our low-band spectrum,” said Irizarry. “Right now, it’s being deployed on our low-band and mid-band licensed spectrum.”
But CBRS GAA spectrum is available to anyone in areas where it’s not in use by the U.S. government (primarily the Navy). So, UScellular decided to tap CBRS spectrum and work with Tarana to deploy the vendor’s FWA equipment on UScellular towers. Tarana’s technology can use either licensed or unlicensed spectrum.
Tarana has more than 200 service provider customers. Tarana CEO Basil Alwan said that at first about 70% of its customers used unlicensed spectrum, while 30% used licensed. But now, it’s about 50/50.
Capacity has been an issue for Verizon and T-Mobile as well. T-Mobile has been especially vocal about not overburdening its mobile network with fixed wireless customers. Irizarry said, “Fixed wireless is going pretty fast. At some point you either have to add capacity or shut off the sales. Once you use up the capacity, using traditional technologies is not economic. We’re excited about the Tarana product, it gives carriers the ability to continue to sell beyond the point when you exhaust traditional capacity.”
It’s not that Tarana is boosting capacity on the 3GPP network. It simply uses the same towers to put up its systems and tap the free CBRS spectrum. Alwan said Tarana’s technology is “really built for fixed wireless.” The company has especially made a name for itself with its proprietary interference cancellation.
“The 3GPP is a great network,” said Irizarry. “But it’s trying to service very different use cases — mobility, fixed wireless and in some cases IoT. Any time you try to meet those requirements, you end up sub-optimizing maximum performance for the use cases.” He said Tarana’s technology is optimized for fixed wireless.
Irizarry said the “initial performance is fantastic.” It’s delivered internet speeds as high as 500 Mbps down and 104 Mbps up.
“Our hope would be we would use it anywhere we run out of capacity,” said Irizarry.
Although Tarana’s technology can work on any spectrum, whether 3GPP or not, its customer premise equipment is proprietary.
Irizarry refused to comment on UScellular’s plans in light of the sale of assets to T-Mobile. He would say only, “T-Mobile is buying our assets which include about 30% of our spectrum. The remaining spectrum we will look to monetize. We have not decided what that monetization looks like. We have a business to run. We’re competitors with T-Mobile.”
To dig a bit deeper, Fierce reached out to Recon Analytics analyst Roger Entner, asking why UScellular might be working with Tarana on FWA, given the fact that it wants to sell most of its assets to T-Mobile.
Entner noted that all of UScellular’s customers and most employees will go to T-Mobile, if the deal is approved by the Department of Justice and the FCC. The only thing remaining will be some spectrum and 4,388 towers. He said they’ll essentially be just a tower company.
Entner said that in the interim, “They are still a going concern. Legally speaking, they have to continue operating as if the sale might not happen. If they have contracts that they signed before the T-Mobile deal, they have to continue this. Otherwise, they’re in legal trouble. If UScellular would not compete against T-Mobile that would be a ground to not approve this sale. Only once this sells, then T-Mobile takes over and makes decisions.”
In terms of working with Tarana, if its FWA technology proves to be an effective and economical way to add more capacity, then T-Mobile may be interested in working with Tarana more expansively. “Tarana will work really hard so this performs really well, and then T-Mobile can look at it,” said Entner.

Austrian energy service provider evolving existing network to meet rapidly growing capacity demand and offer 10g, 25g and 100g mobile backhaul and fronthaul services.
Faced with rapidly growing capacity demand, Austrian energy service provider illwerke vkw has tapped Nokia to evolve its existing network to a modern infrastructure based on dense wavelength-division multiplexing (DWDM) and high-performance photonic service engine (PSE) technology capable of increasing network scale, optimising performance and ensuring sustainable growth.
The leading energy service, power utility and telecoms service provider in the Austrian state of Vorarlberg, illwerke vkw generates its power exclusively from renewable sources. It supplies energy to around 200,000 customers and offers telecoms services to mobile network providers (MNOs). The new deployment, which is expected to be completed by late 2024, is intended to provide illwerke vkw with a new, resilient, modernised optical network capable of supporting 400G wavelengths and beyond for business customers.
Featuring Nokia’s 1830 Photonic Service Switch (PSS) , the new optical network will span 15 sites in Vorarlberg providing 10G, 25G and 100G mobile backhaul and fronthaul transport services to connect MNO cell sites and central offices. Illwerke vkw AG will also provide optical transport services for other business customers in the region.
Commenting on the deployment, illwerke vkw head of IT Christoph Märk said: “We are excited to work with Nokia to evolve our existing network infrastructure. The new optical network will enable us to meet the growing capacity demands and provide high-quality telecoms services to mobile service providers and business customers in Vorarlberg.”
Matthieu Bourguignon, senior vice-president and head of Europe for network infrastructure business at Nokia, added: “As a premier energy service provider in Austria, illwerke vkw AG stands out by harnessing renewable energy and extending its network and expertise to offer telecommunications services to mobile network operators.
“Like its global counterparts in the energy and telecoms sectors, our customer is facing unrelenting demand for capacity which requires significant network modernisation. Nokia will provide a resilient and superior optical transport network capable of supporting 400G wavelengths and beyond, which will serve the present and future requirements of illwerke vkw AG’s customers.”
Nokia is confident the new network will allow illwerke vkw to manage wavelengths at the photonic layer efficiently. It will include optical channel protection to enhance resiliency of services and support for all fronthaul protocols, making the network ready to support multi-generation radios (3G/4G/5G). This includes support of high-performance synchronisation distribution (frequency/time/phase) meeting strict (ITU-T G.8273.2 Class B and C) timing requirements for backhaul and fronthaul services as enabled through the 1830 PSS and 1830 Time-sensitive Packet Switch (TPS), respectively.
The new optical network also employs the Nokia WaveSuite Network Operations Centre (WS-NOC), providing unified end-to-end optical management and support functions including service provisioning and service assurance.

James and manual discuss the planning of project resources.
James is a project planner at Hybrid Machinery. Manuel is responsible for capacity planning and resource and material procurement. They are discussing the management of project resources.
You can use activities in a network to plan the resources required for a project.
The SAP Project System (PS) distinguishes between the following types of activities:
Defines the work to be carried out by machines or people. You can evaluate the capacities of the various work centers involved, reschedule these capacities as necessary, and distribute work among employees.
Defines activities that are required from external resources like vendors and subcontractors. External processing is carried out by the purchasing department.
A service activity is also used to procure services externally. It is defined by service specifications and value limits that can be rendered by the service provider. Service processing includes maintenance of service entry sheets. Service processing is carried out by the purchasing department.
Processing of internal project network activities.
Internally processed activities are used to plan work that is to be carried out within your company.
You must define additional data for internally processed activities so the system can create capacity requirements and calculate costs for the following:
A work center is the place where an activity is carried out or work output is produced. A work center contains the scheduling and capacity data required for scheduling and capacity planning. A work center also contains data for costing.
Work is the planned output of machines or personnel to complete an activity.
The duration specifies for how long an activity lasts.
The activity type (and the cost center derived from the work center) specify a price for calculating the planned costs of an activity.
You can determine how much of the work center capacity is used for the activities. If necessary, you can use the Project Planning Board to level capacities. When you confirm activities during the project execution phase, you enter actual dates.
Workforce planning, james and manuel discuss the planning of the internal workforce.
James is a project planner at Hybrid Machinery. Manuel is partly responsible for capacity planning. They discuss the required planning activities for the internal workforce.
"After the work has been completed, the work center where the work was executed out is available again for other tasks."
Once you have created capacity requirements, you can enter workforce planning. Using workforce planning, you can distribute work among employees, that is, you can assign persons to activities. You can also schedule personnel for an activity. Project and work center views are available to help you distribute work among employees. In both views, you can assign persons to activities and access various reference data, such as the availability of a person from Human Capital Management (HCM).

WMN. To take advantage of the increased capacity in such networks, we need to consider several issues: topology for-mation, radio link scheduling, interference mitigation, and routing [2]. The key issue to be addressed in MCMI WMN and the focus of this paper is channel assignment. We con-sider this issue in the context of ieee 802.11s networks.
The required optimal network capacity assignment will be the one represented by the best individual of all generations. 4.8 The routing algorithm used in the overall SA-based algorithm Given the capacities of all links of the given network topology in the form of a capacity solution, the steps of the algorithm that solves the flow assignment ...
The basic outline of core capacity planning tasks is very straightforward. You just need to work out the following three factors: Current system potential capacity. Current capacity utilization. Bandwidth demand of new equipment/software. If you currently run a network, you may scoff at the simplicity of that outline.
The robust design problem (RDP) in a capacitated flow network is to search for the minimum capacity assignment of each edge such that the network still survived even under the edge's failure. The RDP is known as NP-hard. Thus, capacity assignment problem subject to system reliability and total capacity constraints is studied in this paper.

A mixed-integer non-linear model is proposed to optimize jointly the assignment of capacities and flows (the CFA problem) in a communication network. Discrete capacities are considered and the cost function combines the installation cost with a measure of the Quality of Service (QoS) of the resulting network for a given traffic. Generalized Benders decomposition induces convex subproblems ...

Let G = (V, E) be a flow network with flow f. The residual capacity of an augmenting path p is. The residual capacity is the maximal amount of flow that can be pushed through the augmenting path. If there is an augmenting path, then each edge on it has a positive capacity. We will use this fact to compute a maximum flow in a flow network.
BELLEVUE, Wash. — March 6, 2024 . Light it up!
