Overview of Spectrum Enterprise

Spectrum Enterprise is the business services division of Charter Communications. Founded in 1993, the company is headquartered in Stamford, Connecticut, and operates primarily in the United States.

With 89,000 employees, it is part of a Fortune 100 company, ranking 76th. The company focuses on providing technology solutions that scale with an organization's needs, from midsized businesses to large enterprises.

A key part of their approach is offering flexibility to support a company's growth. For some of its services, Spectrum Enterprise also offers a 100% uptime Service Level Agreement (SLA) guarantee.

Overview of Frontier Communications

Frontier Communications has corporate roots that trace back to 1935. The company is headquartered in Dallas, Texas, and serves 25 states across the U.S. with a team of 13,000 employees.

The provider focuses on its 100% fiber-optic network, which offers symmetrical upload and download speeds and has a 99.9% overall network reliability. Frontier also provides solutions for internet backup and offers month-to-month billing for some business customers, avoiding long-term contracts.

ISP Products

Dedicated Internet (DIA)

Spectrum Enterprise provides Dedicated Internet Access with speeds from 20 Mbps to 100 Gbps over fiber, coax, or a hybrid network. Our data shows their 1Gbps DIA circuits are priced about 14% below the market average, though their 100Mbps circuits are 7% higher. Installation timelines are also slightly faster than average at 73 days, compared to the market's 77-day average.

Frontier's Dedicated Internet Access runs on a fiber/Ethernet network with speeds from 5 Mbps to 100 Gbps. They are competitively priced across the board; our data indicates their 100Mbps and 1Gbps circuits are 12% and 11% below the market average, respectively. Their installation time aligns directly with the market average of 77 days.

Both providers guarantee 99.99% uptime and offer common add-ons like managed routers and security services. A key operational difference, however, is the delivery point. Spectrum typically delivers service directly to your suite, while Frontier delivers to the building's main point of entry (MPOE), which can impact your internal cabling needs and costs.

Please note that these are aggregate figures. Actual pricing and installation timelines can vary significantly based on your region and specific DIA configuration.

DIA Pricing, Delivery and Install Days Compared

The data in this table comes from Lightyear’s aggregated ISP quotes collected in 2024 and 2025 YTD.

• Install Days: how long it typically takes to deliver service.
• 100Mb Price vs Avg / 1Gb Price vs Avg: shows whether this ISP is cheaper or more expensive than the market average.
• Delivery Point: “Suite” means the ISP delivers service all the way to the company’s server room; “MPOE” means the circuit stops at the building’s minimum point of entry (typically the building's utility basement) and the tenant must handle the inside wiring.

Wireless

Spectrum Enterprise’s wireless offering is Spectrum Mobile, a service designed for phones and personal devices. It runs on Verizon's 5G network and is supplemented by a network of WiFi hotspots from existing Spectrum modems.

Frontier Communications takes a different approach and does not market a direct mobile plan. Instead, they offer managed cellular failover as a business continuity solution, providing a backup internet connection for branch sites using various carriers' LTE or 5G networks.

This highlights a key distinction for IT buyers: Spectrum Mobile is a consumer-focused service, while Frontier’s cellular failover is a business-grade backup solution. For organizations that depend on constant connectivity, Frontier's solution can inherit the SLA from its parent managed service, a guarantee not offered with Spectrum's mobile plans.

Security

Spectrum Enterprise provides security solutions that scale based on business size. For smaller businesses, a desktop security suite from F-Secure is included with their internet service at no extra cost. Larger organizations have access to a suite of managed security solutions, including network protection on Fortinet and Cisco Meraki platforms, cloud security via Cisco Duo, and a separate DDoS mitigation service.

Frontier Communications, on the other hand, bundles its security features with its managed connectivity products. Their security packages are layered onto their Managed Dedicated Internet service and include features like a firewall, Unified Threat Management (UTM), and web filtering. A key component of Frontier's offering is the 24/7 monitoring and management provided by their team.

Broadband

Spectrum Enterprise offers broadband through its Spectrum Business Internet product, which runs on a hybrid fiber-coax network. This service provides asymmetrical speeds up to 1 Gbps download and 35 Mbps upload, with a 100% uptime SLA and unlimited data. Our data shows Spectrum's broadband is priced about 43% below the market average, with installation times of 26 days—slightly faster than the 28-day average.

Frontier's broadband solution is Frontier Business Fiber, which operates on a 100% fiber network. This allows for symmetrical speeds that can reach up to 7 Gbps in select markets, a significant advantage for businesses needing high upload capacity. While Frontier cites 99.9% network reliability, specific SLA details can differ from their enterprise-grade DIA services.

Due to limited quoting history for Frontier's business broadband, we’re not able to provide benchmark pricing or installation timelines at this time. You can get the latest pricing and availability for your specific location by filling out our questionnaire to receive a direct comparison based on real-time quotes.

Ethernet

Spectrum Enterprise delivers its Ethernet services over a hybrid fiber-coax (HFC) network, the same infrastructure used for its Spectrum Business Internet product. This service provides asymmetrical speeds with up to 1 Gbps downloads and 35 Mbps uploads and is backed by a 100% uptime SLA.

Frontier Communications, in contrast, offers MEF-compliant Carrier Ethernet services, including Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL). These services are designed for building private, high-capacity networks between locations, with optical transport speeds available up to 100 Gbps.

For an IT buyer, the main difference is that Spectrum's offering is a high-speed internet connection over their broadband network, while Frontier provides a dedicated, fiber-based solution for connecting multiple sites.

POTS Replacement

Spectrum Enterprise and Frontier Communications approach POTS replacement from two different angles. Spectrum offers Spectrum Business Voice, a VoIP phone service with unlimited calling and 35+ features, while Frontier provides POTS Connect, a dedicated solution for replacing analog lines for specialty equipment like alarms, faxes, and elevators.

This difference is crucial for IT buyers managing specific systems. Frontier’s service is designed to support these specialty lines, whereas Spectrum’s terms prohibit use for fire alarms and medical alert systems. For resilience, Frontier uses LTE or a wired backhaul, while Spectrum’s service includes an 8-hour battery backup and has an optional wireless failover.

Other Key Features Compared

Geographic Coverage

Spectrum Enterprise focuses its services exclusively within the United States.

While their network is extensive, it's important for IT buyers to know that they operate in just one country.

Frontier Communications also focuses its network within the United States. They provide service in 25 states, so checking availability for your business locations is a key step.

SLA

Spectrum Enterprise provides a 100% uptime Service Level Agreement (SLA) for certain services, including DIA and Ethernet. This is their promise of total reliability for your connection.

Frontier Communications offers a 99.99% uptime guarantee on its DIA services and notes 99.9% reliability for its overall fiber network.

For your business, a 99.99% SLA translates to less than an hour of potential downtime per year. A 100% SLA typically means you'll receive service credits for any outage, no matter how brief.

Transport Types Available

Spectrum Enterprise operates on a hybrid fiber-coax network, supported by 230,000 fiber route miles. This setup provides a range of speeds suitable for everything from daily business tasks to streaming.

Frontier Communications uses a 100% fiber-optic network across its 180,000 fiber route miles. This allows for symmetrical speeds, a big plus for businesses that handle large uploads or rely on video conferencing.

While Spectrum's large network offers broad coverage, Frontier's all-fiber infrastructure is ideal for businesses needing equal upload and download performance.

Customer Support

Spectrum Enterprise provides dedicated, U.S.-based customer support for its business clients. You can expect 24/7 assistance for technical issues, ensuring help is available whenever you need it.

Frontier Communications also offers around-the-clock support for its business customers. Their support teams are trained to handle issues specific to their fiber-optic network and managed services.

For an IT buyer, both providers have support structures built for business needs. The actual experience can vary by region, so it’s wise to check recent customer feedback for your specific area.

Final Verdict: Spectrum Enterprise or Frontier Communications?

Choosing between Spectrum Enterprise and Frontier Communications depends entirely on your specific business needs. Both are strong providers, but their core differences in network infrastructure and service offerings will likely make one a better fit for your organization.

Spectrum Enterprise is a great choice for businesses that prioritize competitively priced broadband and want the convenience of DIA service delivered directly to their suite. Their extensive hybrid fiber-coax network provides broad coverage across their service areas.

On the other hand, Frontier is an excellent option for companies that require the symmetrical upload and download speeds of a 100% fiber network. They are also a better fit for organizations needing dedicated Ethernet for multi-site connectivity or a specialized POTS replacement solution.

Ultimately, the right choice is location-dependent. To make a fully informed decision, we recommend comparing direct quotes for your specific addresses to see which provider offers the best value and performance for you.
