Charter Communications: surprise drop in broadband subs, homes passed increased, HFC network upgrade delayed to 2026
Charter Communications posted a surprise drop in broadband subscribers in the Q4-2023, the company announced on Friday. Charter’s internet customers decreased by 61,000 (-62,000 residential and +1,000 business) in the 4th quarter, with nearly all of the decline from residential customers. That was much worse than expectations for 17,290 additions, according to Visible Alpha and a year-ago gain of +105,000. The broadband subscriber drop was especially disappointing given Charter’s homes passed growth accelerated to 2.5% year-over-year, Craig Moffett said in a research note.
“Internet growth in our existing footprint has been challenging, driven by admittedly more persistent competition from fixed wireless and similar levels of wireline overbuild activity,” CEO Chris Winfrey said on a post-earnings call, adding that new investments will help drive growth despite the “temporary challenges.” Chief Financial Officer Jessica Fischer had warned in December that the company could lose internet customers in the quarter. At the time, speaking at an analyst conference, she said the company was facing short-term challenges and that results would be in line with the rest of the industry.
Charter was not the only cableco/MSO to report decreased broadband internet subscribers in the 4th quarter. Last week, rival Comcast reported a loss of 34,000 broadband customers, fewer than expectations, but exceeding the 18,000 broadband customers it lost in the previous quarter.
Stiff competition across broadband and wireless mobile and the decline of traditional television have been causes of concern, with Charter trying to expand its reach into rural areas in an effort to boost subscriber and earnings growth. Charter is facing heightened competition from Verizon and T-Mobile’s wireless home internet offerings, and the cable company could soon lose even more subscribers when a key government program runs out of funding in April, JPMorgan analysts say in a research note. In particular, the end of the Affordable Connectivity Program (ACP), which provided up to $30 per month to eligible customers to put toward their internet bills, could hurt Charter more than its peers. If ACP is not refunded, “we’ll work very hard to keep customers connected,” Winfrey said. Charter has more than 5 million ACP recipients, the highest in the industry. The majority of them were Charter broadband subscribers before the program began.

Charter added 142,000 broadband subs via its rural subsidy program in Q4, for a total of 420,000, and an overall penetration rate of 33.8% – up from 27.2% in the year-ago quarter. The company posted $74 million in rural revenues, up from $39 million a year earlier. Charter pulled in subsidy revenues of $29 million in Q4. Total capex for the project in Q4 was $426 million, down from $567 million in the year-ago quarter. Charter plans to activate 450,000 new subsidized rural passings in 2024. With all programs rolled up, Charter has committed to build 1.75 million subsidized rural passings.
Charter expects to complete its Rural Digital Opportunity Fund (RDOF) builds by the end of 2026 – two years ahead of schedule. Charter also intends to participate in the much larger $42.45 billion Broadband Equity Access and Deployment (BEAD) program.
……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………..
Completion of Charter’s hybrid fiber/coax (HFC) network upgrade has been delayed to 2026 due in part to a lengthier certification process for distributed access architecture (DAA) technology. Charter’s original plan was to complete its HFC upgrades by the end of 2025. Charter’s HFC evolution plan consists of three steps:
- An upgrade to 15% of its network to 1.2GHz with an upstream-enhancing “high-split” using traditional integrated cable modem termination systems (CMTSs). That enables multi-gigabit downstream speeds and upstream speeds up to 1 Gbit/s.
- An upgrade to 1.2GHz with DAA and a virtual CMTS in 50% of the HFC footprint, enabling downstream speeds up to 5 Gbit/s and upstream speeds up to 1 Gbit/s.
- A full DOCSIS 4.0 upgrade by deploying 1.8GHz with DAA and a vCMTS to 35% of the HFC footprint. That’ll put Charter in position to deliver up to 10 Gbit/s downstream and at least 1 Gbit/s upstream.
Speaking on today’s Q4 2023 earnings call, Charter CEO Chris Winfrey said the operator has launched symmetrical speed tiers in two markets (Reno and Rochester, Minnesota, an official confirmed), with deployments in six additional markets underway that, once completed, will fulfill the phase one plan. Charter expects to start DAA deployments in its phase two markets later this year, Winfrey said.
……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………..
Charter added 546,000 mobile lines in Q4, down from a gain of +615,000 in the year-ago quarter and +594,000 in the prior quarter. Analysts were expecting Charter to add 594,000 mobile lines in the 4th quarter and +2.5 million lines for full 2023, up from 1.7 million in full 2022. The MSO ended 2023 with 7.76 million mobile lines. Charter is also expanding its deployment of CBRS spectrum to help the company offload MVNO costs in high-usage areas. Winfrey said “thousands” of CBRS units have been deployed in one “large” market (believed to be Charlotte, North Carolina). Charter expects to roll CBRS to an additional market later this year, he said.

IEEE President’s Priorities and Strategic Direction for 2024
by Tom Coughlin, 2024 IEEE President; edited & augmented by Alan J Weissberger, IEEE Techblog Content Manager
Let’s examine each of these issues and initiatives for IEEE this year:
1. IEEE has a lot of college student members but, like many other professional organizations, the majority of these student members don’t continue as full IEEE members. One reason is the much higher cost – $218/yr for full IEEE membership vs. $32/yr for IEEE student membership. This is a big financial burden as many college graduates carry student loans after graduation. Another reason is they don’t see much if any value in being an IEEE member. We need to change that perception by revitalizing IEEE such that is relevant to young members careers in both industry and academia.
In order for the IEEE to remain vital and relevant we need to convert more of our student members to full IEEE members and then engage and retain them. One thought is to encourage them to volunteer at the section, chapter, or global level.
I am creating a special task force in the IEEE to address this problem and do surveys, focus groups and pilot programs to find ways that we can attract and retain our younger members.
2. IEEE needs to create stronger ties and provide greater value to industry and to those engineers and scientists who work in industry. This goal is closely related to the first goal since most of our student members end up working in industry.
IEEE has an Industry Engagement Committee and I have asked them to work with the IEEE Student Activities Committee and IEEE Young Professionals to find value in the IEEE for younger people working in industry. In addition, I am personally reaching out to companies to speak with senior technical people about how IEEE is useful now and what else we can do to provide value, particularly for younger people working in industry.
3. IEEE needs to reach out to the broader world to let them know who we are and what we do. Today, most people that have heard of IEEE think of it as ONLY a standards organization, e.g. for IEEE 802.11 WiFi and IEEE 802.3 Ethernet. They don’t realize that IEEE is by far, the largest tech non-profit organization.
We have in our IEEE membership experts in all technologies, who can provide insights and guidance for public policy, convene meetings and create new and valuable standards.
IEEE is by far the most cited source for prior art in patents worldwide, it has created documents and standards on ethical design of intelligent and autonomous systems (AI) and our volunteers write, review and publish much of the worlds technical literature and put on conferences on every conceivable technical topic.
IEEE also creates future directions committees on emerging technologies, pursue technical megatrends and create and publish technology roadmaps on semiconductor and other important technologies.
4. IEEE needs to invest in new products and services. In particular, applying AI and other computer algorithms to IEEE content that will enable new ways to find, understand and advance technologies that can serve our members and our customers.
In 2024, IEEE will start an Ad hoc committee, working with relevant groups outside of the IEEE, on educating future generations of workers who will be using new tools such as AI, working in outer space and in virtual environments and who will work for many organizations and technologies during their career.
IEEE should be able to leverage technical tools to help people learn in the best way for them and to provide lower costs for continuous education which can enable those from underserved communities to participate in and benefit from technical education.
……………………………………………………………………………………………………………………
2024 IEEE Key Topics of Focus Overview:
- Provides a roadmap for the year in terms of areas of focus and provides year over year continuity.
- Discussed and adopted on an annual basis by the IEEE Board of Directors at the January meeting.
- A living document that evolves throughout the year and is updated for every Board meeting as progress is reported.
Tom’s Closing Comments:
I know the time will go by fast in my one year term as IEEE President. I look forward to meeting more of our members in more places and having the chance to understand and support these members. I also hope that I can help create stronger ties to those who work in industry and keep more of our younger members and provide greater value to the world. Most of all I will support the IEEE’s mission to advance technology for the benefit of humanity!

IEEE President Elect: IEEE Overview, 2024 Priorities and Strategic Plan
SK Telecom, Intel develop low-latency technology for 6G core network
In collaboration with Intel, SK Telecom (SKT) has successfully developed technology to reduce communication delays necessary for the evolution of 6G Core Network Architecture. The Core network is the gateway through which all voice and data traffic generated from a customer’s mobile device passes through to access the Internet network. It is a mobile communication service system that is responsible for security and service quality through the inter-connection of various systems.
Editor’s NOTE: Of course, 6G is currently undefined with only the features and functions being defined by ITU-R WP 5D which is meeting this week in Geneva. The 6G core network specifications will be done by 3GPP and NOT ITU-T as was the case for 5G core.
…………………………………………………………………………………………………………..
The 6G Core Architecture is required to have higher flexibility and safety than previous generations of wireless communications, and to provide stable AI service quality and technologies to customers by embedding intelligent and automation technologies.
As Core network technology continues to develop, the various systems that make up the network and the detailed functions that provide various services are also explosively increasing. As network complexity continues to increase, the process of sending and receiving messages is frequently recreated. Therefore, communication delays will increase compared to before. It is difficult to address these limitations with communication standard technologies (service communication proxies) for interconnection between unit functions within the existing Core network.
Inline Service Mesh, a low latency technology the two companies developed utilizing Intel Xeon processors with built in AI, is capable of increasing the communication speed within the Core network by reducing latency between unit function without Proxy.
Through this technology development, AI, which requires a large amount of computation, can be applied to the Core network in a wider variety of models. SKT has already commercialized a technology that reduces wireless resources by 40% and improves connectivity by analyzing movement patterns of real users in real time. Through this cooperation, the two companies will be able to reduce communication delays by 70% and increase service efficiency by 33% in the Core network through the application of the 6G Core Architecture.
SKT aims to apply the results of this study to commercial equipment next year. A technical white paper has been published by Intel that describes the technology, development process and benefits.
SKT and Intel have been continuing to cooperate for research on the development of key wired/wireless mobile communication technologies for the past 10 years. Based on the results of this study, the two companies plan to continue research and development for traffic processing improvement technologies incorporating AI technology in various areas of the Core network.
“We have made another technical achievement through continuous technology development cooperation with Intel to secure leadership in 6G,” said Yu Takki, Vice President and Head of Infra Tech at SKT. “We will continue our research and make efforts to commercialize AI-based 6G Core Architecture.”
“Our research and development efforts with SK Telecom continue to deliver innovations that have been deployed by Communications Service Providers worldwide”, said Dan Rodriguez, Corporate Vice President of Intel Network & Edge Solutions Group. “By leveraging the latest Intel Xeon processors with built in AI features, our companies are able to drive both performance and efficiency improvements that will be vital to the future Core networks.
Last March, SKT and NTT DOCOMO released a white paper addressing the requirements for future 6G networks.
The South Korean carrier said the new white paper contains its views on 6G key requirements and 6G evolution methodology, along with its opinions on the latest trends in frequency standardization. The 6G white paper also provides analysis, development directions and methodologies pertaining to promising 6G use cases, technology trends as well as and candidate frequencies.
The 6G White Paper reviews the following:
- Performance requirements and implementation scenarios for each frequency band, taking into account the characteristics of each frequency
- Issues concerning coverage and devices in high-frequency bands
- Standardization for migration to 6G architecture and application of cloud-native / open architecture

Calix and Corning Weigh In: When Will Broadband Wireline Spending Increase?
Broadband wireline network operators (telcos and MSOs/cablecos) have cutback on CAPEX with decreased spending for network equipment. In its latest earnings call, Calix warned that broadband operator spending might not increase until 2025, when BEAD subsidies have been allocated. However, fiber vendor Corning and others suggested spending might increase earlier than that.
Calix specializes in providing optical network access equipment to smaller broadband service providers and has seen significant revenue growth in recent years, but near-term growth will be challenged. Calix management’s guidance was that the 2024 fiscal year will be soft for its business. Despite that softness, the company still believes that it has years of growth ahead for itself starting in 2025 due to BEAD regulatory stimulus that should prove beneficial for the enterprise.
The U.S. government’s BEAD program promises to funnel a massive $42 billion in subsidies through US states to telecom companies willing to build networks in rural areas. However, allocation of those funds is taking longer than expected, forcing network operators to stall their deployment plans until they have a better sense of how much funding they might get.
“We have seen a significant broadening in the number of customers interested in competing for BEAD [Broadband Equity Access and Deployment program] funds. Today, nearly all our customers are either assembling a BEAD strategy or actively pursuing funds,” Calix CEO Michael Weening said during the company’s quarterly earnings call, according to Seeking Alpha.
“While they do this, they slow their new [network] builds as BEAD money could be used instead of consuming their own capital, and thus, we’ll slow our appliance shipments until decisions are made and funds are awarded,” Weening said. “At that point, the winners will move ahead and those who decided to skip the BEAD program or did not receive BEAD funding, we’ll begin investing to ensure that the winner does not impinge on their market. This represents a delay but also represents a unique opportunity for Calix.”
……………………………………………………………………………………………………..
Corning manufactures and sells most of the physical fiber cabling used in U.S. fiber networks. Sales in Corning’s optical business unit – which houses its fiber products – continued to slide in the fourth quarter of 2023.
“We anticipate optical communications sales will spring back because we believe and our carrier customers have confirmed that they purchased excess inventory during the pandemic and that they’ve been utilizing this inventory to continue deploying their networks,” said Corning CEO Wendell Weeks during his company’s quarterly earnings call, according to Seeking Alpha.
“We believe these carriers will soon deplete their inventory and execute on the increased broadband deployment plans they’ve communicated to us over the last several months,” Weeks said. “As a result, we expect them to return to their normal purchasing patterns to service their deployments.”
He also noted that operators are waiting for BEAD funding. “We continue to expect BEAD funding really to start to translate into demand, the beginning of it, sort of late this year. They are progressing with awarding the grants and it will just take a bit for those to turn into real programs,” Weeks said.
Weeks suggested that the company is starting to see the glimmer of an uptick in demand from its broadband operator customers, but nothing definite yet. “We’ll know more in the coming months,” he said in his concluding remarks.
Meanwhile, executives at vendor Harmonic said this week they expect sales in the first half of this year to be relatively soft and then accelerate in the second half of the year as operators start to ramp up network upgrades, including moves to DOCSIS 4.0 technologies.
OIF Project Highlights: Interoperable 1600ZR+ & Retimed Tx Linear Rx Specs Energy Efficient Interfaces; Common Management Interface Specification (CMIS) Whitepaper

Global 5G Market Snapshot; Dell’Oro and GSA Updates on 5G SA networks and devices
According to market research firm Omdia, there were 1.8 billion global 5G subscribers at the end of 2023 with 7.9 billion forecast by 2028. This growth trajectory, while substantial, is subject to various influencing factors such as infrastructure development, spectrum availability, device availability, and consumer demand. Kristin Paulin, Principal Analyst at Omdia, has a cautiously optimistic outlook for 5G. She emphasizes that innovation and cooperation are key to unlocking the full potential of 5G and its transformative impact.
Globally, the number of deployed 5G networks is now comparable to 4G LTE deployments. There are currently 296 commercial 5G networks worldwide, a number expected to grow to 438 by 2025.
In North America, 5G deployment was at 176 million connections as of the third quarter of 2023, a 14% increase from the previous quarter. This represents a 26% market share and a 46% penetration rate. However, there were only two U.S. 5G SA network providers – T-Mobile US and Dish Wireless– as of the end of 2023.
in contrast, Latin America and the Caribbean are still in the early stages of 5G adoption. However, the region shows promise with an expected quadrupling of 5G connections in 2023, reaching 46 million. By 2028, it is anticipated that the region will have 492 million 5G connections.
Jose Otero, Vice President of Caribbean and Latin America for 5G Americas, acknowledges the significance of 4G LTE and 5G as vital mobile communication technologies in Latin America. He anticipates more robust opportunities for 5G in the region, driven by upcoming spectrum auctions and wider access to 5G devices in 2024.
“The global 5G landscape shows positive momentum as innovation and collaboration continue to be the mainstays for long term progress.” said Chris Pearson, President of 5G Americas. “With the World Radio Conference wrapping up, it is important that international co-operation and efforts continue to ensure that spectrum and technology standards continue to propel this growth.”

According to a recent report by Dell’Oro Group, the Mobile Core Network (MCN) market growth rate has been reduced to less than a 1% CAGR (2023-2028).
“This is the fourth consecutive time we reduced the growth rate of the MCN market as the build-out of 5G Standalone (5G SA) networks continues to wane compared to 5G Non-standalone (5G NSA) networks,” said Dave Bolan, Research Director at Dell’Oro Group. “The buildout of 5G SA networks is going slower than anticipated which is restraining growth in the marketplace. To date, we count fifty 5G SA eMBB (enhanced Mobile BroadBand) networks that have been commercially deployed worldwide by Mobile Network Operators (MNOs). We counted 18 new 5G SA networks in 2022, but only 12 were launched in 2023. On a positive note, we believe a lot of work has been done in the background, preparing for 5G SA launches by Mobile Network Operators (MNOs) and we expect 2024 to have more launches than 2022.”
Note 1. Importantly, a 5G SA core network is required to realize 3GPP defined 5G features, like 5G Security, Network Slicing (3GPP’s technical specification (TS) 23.501 defines 5G system architecture with slicing included. TS 22.261 specifies the provisioning of network slices, association of devices to slices, and performance isolation during normal and elastic slice operation).
The 5G SA core network relies on a “Service-Based Architecture” (SBA) framework, where the architecture elements are defined in terms of “Network Functions” (NFs) rather than by “traditional” Network Entities.
5G SA core networks require “cloud-native” hardware and software that has a service-based architecture and decentralized functions. A “cloud-native” 5G core allows for flexible and efficient operation, as well as the effective adoption of new services.
………………………………………………………………………………………………………..
According to Verified Market Research, when the full 5G SA feature set is supported, enterprises can realize the following benefits:
- Further improvements to speed and reach, beyond what 5G NSA brings.
- Support for higher-density deployments of devices.
- Support for low-latency and real-time use cases.
- Support for enhanced enterprise site connectivity via network slicing.
- Better security than 5G NSA (which uses 4G LTE security methods and procedures).
- Simplification of the RAN and core compared to 5G NSA since 5G SA supports only 5G and leaves 4G and older standards behind — and even though the 5G SA core alone is more complex than a pure 4G core alone.
GSA claims that more than 121 network operators in 55 countries and territories have invested in public 5G standalone (SA) networks (but they don’t disclose how many of those have been commercially deployed (for example, AT&T and Verizon have been talking up 5G SA for years, but have yet to deploy it!). We trust Dell’Oro’s number of 5G SA eMBB networks deployed.
Findings from the latest GSA update on the 5G SA ecosystem/devices [2.] include:
- There are 2,130 announced devices with claimed support for 5G SA, up 35.7% from 1,569 at the end of 2022.
- Devices with support for 5G SA account for 90.3% of all 5G devices, as of the end of 2023, up from 35.6% in December 2019.
- 93 modems or mobile processors/platform chipsets state support for 5G SA, 90 of which are understood to be commercially available.
Note 2. It’s crucially important to realize that since all 5G SA core networks are different, a 5G SA device that works on one carrier’s network won’t work on any other without a new 5G SA download.
By the end of December 2023, GSA had identified:
• 28 announced form factors • 261 manufacturers with announced available or forthcoming 5G devices
• 2,358 announced devices, including regional variants, but excluding operator-branded devices that are essentially rebadged versions of other phones. Of these, at least 1,964 are understood to be commercially available:
• 1,255 phones, up 34 from November 2023. At least 1,168 of these are now commercially available, up 56 from November 2023
• 308 fixed wireless access customer-premises equipment (CPE) devices for indoor and outdoor uses, at least 209 of which are now commercially available
• 243 modules • 64 tablets • 33 laptops or notebooks • 77 battery-operated hot spots
• 179 industrial or enterprise routers, gateways or modems
• 13 in-vehicle routers, modems or hot spots
• 29 USB terminals, dongles or modems
• 168 other devices, including drones, head-mounted displays, robots, TVs, cameras, femtocells/small cells, repeaters, vehicle on-board units, keypads, a snap-on dongle/adapter, a switch, a vending machine and an encoder
• 1,098 announced devices with declared support for standalone 5G in sub-6 GHz bands, 904 of which are commercially available.

MIIT: China’s Big 3 telcos add 24.82M 5G “package subscribers” in December 2023
China’s three state owned telecom operators have announced their subscriber totals for the month of December and for all of 2023. China’ Ministry of Industry and Information Technology (MIIT) said the big three had a combined net increase of approximately 24.82M 5G package subscribers in China, boosting their combined 5G package subscriber base to nearly 1.373B.
As of the end of December, 5G package subscribers accounted for 80.2% and 78.1% of China Mobile’s and China Telecom’s total mobile subscriber bases, respectively.
C114.net reported that 3.377 million 5G base stations have been built, constituting 28.5 percent of the total mobile base stations. There are 23.02 million ports with gigabit network service capabilities. More than 80% of administrative villages nationwide now have 5G connectivity, telecoms portal.
The foundation of the Internet of Things (IoT) is constantly being consolidated, with mobile IoT terminal users accounting for 57.5% of the total number of mobile network terminal connections. Technological industry innovation and development, the commercial deployment of 5G customized base stations and 5G lightweight technology, and the launch of the world’s first satellite communication smartphone, 6G, quantum communication, artificial intelligence and other innovative capabilities have significantly improved.
- China Mobile ended last year with 794.5 million subscribers to its 5G package (contract), while its total mobile subscriber base reached 991 million.
- China Telecom had a total of 407.7 million mobile users, of which 318.66 million had signed up to a 5G package (up by 50.7 million during 2023).
- China Unicom’s 5G package subscriber total hit 259.6 million by the end of last year, though disclosure on total mobile subscribers has not been provided. China Unicom also reported that there were 8,563 “virtual 5G industry private network” subscriber for the month of December which was an increase of 554 month-on-month and up 4,758 since the end of 2022.

China’s fourth 5G telecom network operator, China Broadnet, saw its 5G user base surpass 20 mln on October 19, the company revealed at the 2023 World 5G Convention held in Zhengzhou from December 5-7. Since that time, however, China Broadnet has not publicly released any updated 5G subscriber statistics.
Broadnet officially launched 5G network services just 19 months ago, on June 27, 2022. Because Broadnet is not yet reporting its 5G subscriber totals on a regular, monthly basis, Marbridge is not yet integrating its totals with those of China’s three more established telecom operators above.
Cautionary Note:
The Chinese telecom operators specifically report numbers for 5G packages, rather than citing 5G service users or connections, as while customers may have signed up for a 5G service package offer, that doesn’t necessarily mean they have a 5G-enabled device that enables them to hook up to their network operator’s 5G network, or indeed that their service provider is offering 5G services in their area just yet.
In addition to the growing 5G market in China, the fixed broadband segment is also very large. China Mobile had a total of 298 million wireline broadband customers at the end of December 2023, and throughout the year it added a total of 26 million fixed customers. China Telecom had 190 million fixed broadband subscribers by the year end, having added a total of 9.26 million wireline broadband users in 2023. China Unicom’s operational statistics for the last month of 2023 did not provide a breakdown of broadband customers.
