What types of business connectivity are available?

Business connectivity is the collection of access services and network links that connect a business’s sites, users, devices, cloud platforms and external systems. The main options are fixed broadband, dedicated leased lines, Ethernet services, mobile data, point-to-point links and secure overlay networks. Each type differs in how bandwidth is shared, how performance is managed, how sites can be connected and how easily the service can support business-critical applications.

Business broadband is a shared access service delivered over a fixed line, commonly using fibre or a combination of fibre and copper. It is often suitable for smaller offices, individual sites and general internet access. Available upload and download capacity may not be identical, and actual performance can be affected by local infrastructure and contention. Business packages may include features such as a static IP address, business-grade support arrangements or a more clearly defined service level than a residential package, but these features should be checked rather than assumed.

Full-fibre broadband can provide a more consistent access method than connections that rely on copper for part of the route. However, a fibre connection is not automatically a dedicated service. The access network, provider network and service terms still determine how capacity is shared, what faults are covered and whether performance is formally guaranteed. Businesses should therefore assess the service specification, not just the word “fibre”.

Leased lines provide dedicated connectivity between a business location and a carrier or internet service point. Unlike a contended broadband service, the access capacity is reserved for the customer, which makes leased lines relevant where predictable performance, substantial upload capacity or a defined service agreement is important. They are commonly used for voice and video services, hosted applications, cloud platforms, backups and connections between offices. The price and installation requirements depend on the route, site infrastructure and the service selected.

Ethernet connectivity is a family of business access services rather than one single product. It can provide a dedicated connection to the internet, link buildings or connect a site into a private wide area network. Ethernet may be delivered over different underlying infrastructures, so a quote should identify the access technology, handover location, bandwidth, contention model, installation responsibilities and service-level provisions. EFM, or Ethernet in the First Mile, is one form of Ethernet access that uses multiple copper pairs where a suitable fibre service is not available.

Mobile connectivity uses a cellular network to provide internet access through a router, modem or other managed device. It can be used as the main connection for a temporary, remote or hard-to-reach site, or as a secondary path for continuity. Its suitability depends on signal strength, network coverage, indoor building conditions, data allowances and the location of the equipment. Mobile access should be tested at the premises and assessed against expected data use before it is treated as a permanent primary service.

Point-to-point links connect two defined locations directly. They can be used between offices, a head office and a data centre, or separate buildings on the same site. A point-to-point service may carry internal applications, storage traffic, voice services or other private data without sending that traffic across the public internet. The physical route, distance, permissions and endpoint equipment all affect whether this option is practical.

Private networks and secure overlays connect multiple sites and users through controlled logical paths. A virtual private network can encrypt traffic over an underlying internet service, while a managed wide area network can apply routing and security policies across several types of access. These arrangements are useful where users need controlled access to internal systems, or where offices must communicate as one network. Security depends on correct authentication, encryption, routing, firewall policies and endpoint management; the connectivity service alone does not secure every device or application.

Internet access and site-to-site connectivity are different requirements. A business may need a connection from one office to cloud services, a private link between branches, remote access for staff, or a combination of all three. A dedicated internet circuit does not automatically connect two offices privately, and a private site-to-site service may not include direct internet access. Requirements should be documented by traffic type and destination before selecting a service.

Resilience can be designed into the access arrangement. This may involve using two different access technologies, such as a fixed line and mobile service, or obtaining services through physically diverse routes and providers. Two connections should not be assumed to be independent simply because they have separate contracts. If they share a cabinet, duct, building entry point or upstream network, one incident may affect both. The design should identify the intended failure scenario and explain how traffic will be redirected.

Important comparison criteria include:

• download and upload capacity, including whether the speeds are symmetrical;
• contention, usage limits and any traffic management policies;
• latency, jitter and packet loss where voice, video or interactive cloud applications are involved;
• static addressing, routing requirements and compatibility with firewalls or private networks;
• installation method, site access requirements and any constraints in the building;
• fault ownership, escalation arrangements and the service level for the access circuit;
• resilience, route diversity and the operation of any automatic failover;
• contract term, renewal conditions, equipment ownership and charges for changes;
• monitoring, reporting and the information supplied when performance deteriorates.

The most appropriate arrangement is often a combination rather than a single connection type. For example, a business might use a dedicated service for a main office, broadband or fibre access at smaller sites, mobile connectivity for a secondary path and encrypted connections for inter-site traffic. S2 Technology Group can help organisations assess these requirements alongside their cloud, security, remote access and infrastructure needs, then manage the resulting connectivity as part of a wider IT environment.
