Network for SMEs: complete infrastructure guide

Complete network guide for small and medium businesses: what you need, how much it costs and how to start.

What network does an SME need?

Small and medium businesses need a reliable, secure and scalable network. You don't need to spend a fortune, but you do need to invest in the right components.

Essential components

  • Professional router (not the ISP one)
  • PoE managed switch
  • Cat6A or higher cabling
  • Wi-Fi 6 Access Points
  • Organized rack with patch panel
  • UPS to protect equipment

Basic network security

  • Router integrated firewall
  • Separate guest Wi-Fi
  • VLANs to segment traffic
  • Strong passwords and WPA3
  • Regular firmware updates

Budget estimates

  • Small SME (5–10 workstations): €1,500–€3,000
  • Medium SME (10–30 workstations): €3,000–€8,000
  • Large SME (30–50 workstations): €8,000–€15,000

Common SME mistakes

  • Using the ISP router as the only equipment
  • Not separating guest network
  • Low-quality cables
  • Not planning for growth
  • No UPS
