Networking decisions should start with how systems need to communicate, how much traffic is expected and what level of control the network requires.
Switches
Switches connect devices within a network. The choice between managed and unmanaged equipment depends on how much configuration, monitoring and control is required.
Managed switches
Managed switches provide configuration and management capabilities that can be important in business networks where traffic, segmentation and administration need greater control.
Unmanaged switches
Unmanaged switches are designed for simpler deployments where advanced configuration is not required.
PoE and PoE+
Power over Ethernet allows compatible devices to receive power through network cabling. It can simplify the installation of equipment such as wireless access points and other compatible network devices.
Routers and gateways
Routers and gateways perform different network roles from Ethernet switches. The correct equipment depends on the network topology, Internet connection, security requirements and services being provided.
Wireless networking
Wireless performance depends on more than the access point specification. Building layout, coverage, interference, client density, backhaul and network capacity all matter.
Network connectivity
Transceivers, modules, network cards and fibre connections can form part of larger network designs. Compatibility between equipment at each end of a connection should be checked before purchasing.
Questions to answer before buying
- How many wired devices need to connect?
- Which devices require PoE?
- Is network management required?
- What link speeds are required?
- Will fibre be used?
- How many wireless clients are expected?
- Does the network need segmentation or other advanced configuration?
- What expansion is expected?
