More About Oi
Oi is a telecommunications company headquartered in Brazil that delivers fixed and mobile connectivity, broadband internet, and related digital services to consumer, enterprise, and wholesale customers. For enterprise stakeholders, Oi functions as a network and infrastructure provider, supplying IP-based connectivity and managed services that underpin corporate WANs, branch connectivity, and internet access across Brazilian territory.
In the enterprise segment, Oi provides services that align with standard networking and telecom categories, including MPLS-based IP VPNs (networking), dedicated internet access (internet services), and point-to-point data links for interconnecting sites and data centers (networking). These offerings are typically used to connect headquarters, branches, and cloud environments, and to support latency- and bandwidth-sensitive applications such as ERP, collaboration platforms, and contact center systems. Oi also addresses wholesale and carrier customers that require backbone capacity and last-mile access for their own retail or enterprise portfolios (infrastructure services).
Oi’s broadband and fixed-line portfolio for businesses covers access technologies such as xDSL and fiber, depending on regional availability and the customer’s bandwidth requirements (internet services). On top of access, Oi provides services that can include static IP addressing, traffic prioritization options, and Service Level Agreements (SLAs) at the service-plan level, which are used by enterprises for hosting local infrastructure, Virtual Private Network (VPN) termination, and secure remote access gateways. Mobile services extend connectivity to smartphones, tablets, and Internet of Things (IoT) devices, with data plans and voice services that integrate into enterprise communication strategies (mobility services).
From a technology standpoint, Oi’s services are grounded in standard telecom frameworks and protocols, including IP, Multiprotocol Label Switching (MPLS), Ethernet, and typical carrier transport architectures. This allows integration with Customer Premises Equipment (CPE) such as routers, firewalls, Software-Defined Wide Area Network (SD-WAN) appliances, and Wi-Fi infrastructure from various vendors, and enables enterprises to design hybrid architectures that mix private VPNs, public internet, and cloud connectivity. For large organizations and public institutions, Oi positions its offerings as components of broader ICT solutions, frequently combined with managed services, service-level management, and professional support.
Within an enterprise IT directory or marketplace taxonomy, Oi can be categorized under telecommunications carriers, enterprise networking and connectivity, Internet Service Providers (ISP), and managed network and infrastructure services. Its current focus is on delivering connectivity, broadband, and related ICT solutions, rather than application-layer software platforms. For technical buyers, the primary evaluation areas include available access technologies and coverage in Brazil, network performance characteristics, supported enterprise features, and integration with existing Wide Area Network (WAN), security, and cloud architectures.
