5G vs Wi-Fi 6E for Business: Which is Best for Your Office?
Wi-Fi 6E or 5G for the office? We compare real-world speed, cost, security and deployment for Australian SMEs - plus the hybrid setup most businesses should actually run.
Choosing between 5G and Wi-Fi 6E for your business network is no longer a fringe IT debate — it’s a genuine architectural decision. Both technologies promise gigabit-class speeds, low latency, and the ability to support hundreds of devices, yet they solve very different problems. If you’re planning a new office fit-out, refreshing aging access points, or weighing up a private 5G trial, this guide breaks down what actually matters.
The short answer
For most Australian SMEs, Wi-Fi 6E remains the best primary network for in-office connectivity, while 5G is the smarter choice for failover, mobile workforces, pop-up sites, and IoT deployments where running cabling isn’t practical. The two technologies are complementary, not competitors.
Speed and throughput compared
Wi-Fi 6E adds the 6 GHz band to Wi-Fi 6, opening up to 1,200 MHz of fresh spectrum and supporting 160 MHz channels with virtually no DFS interference. 5G, particularly in the mid-band (sub-6 GHz) ranges that Telstra, Optus and TPG operate on in Australia, delivers consistently strong real-world speeds but is shared across many users on the same cell.
| Metric | Wi-Fi 6E | 5G (Sub-6) |
|---|---|---|
| Theoretical max throughput | ~9.6 Gbps | ~10 Gbps |
| Typical real-world download | 800–1,500 Mbps | 200–700 Mbps |
| Typical latency | 2–5 ms | 15–40 ms |
| Spectrum | 2.4 / 5 / 6 GHz (unlicensed) | 700 MHz to 3.7 GHz (licensed) |
| Best for | Dense indoor coverage | Outdoor & mobile |
Cost: capital and ongoing
This is where the two technologies diverge most sharply. A typical Wi-Fi 6E deployment for a 25-person office — including three ceiling-mounted access points, a PoE+ switch, and a controller — will run between $2,500 and $5,500 in hardware, with no ongoing per-device fees. 5G, by contrast, is operating-expense heavy.
Wi-Fi 6E typical costs
- Access points: $400–$900 each (Ubiquiti, TP-Link Omada, Aruba Instant On)
- PoE+ switch: $300–$1,200
- Internet circuit (NBN Enterprise Ethernet, fibre): $200–$1,500/month
- Annual maintenance: minimal — mostly firmware
5G typical costs
- 5G modem/router: $400–$1,800 (Cradlepoint, Teltonika, Netgear Nighthawk M6 Pro)
- Business 5G plan: $80–$250 per SIM, per month
- Per-device data: realistic 1–2 TB/month soft caps
- Private 5G (CBRS-equivalent in Australia is still emerging): $50k+ to deploy
Over three years, a Wi-Fi 6E network for a small office is typically 40–60% cheaper than equivalent 5G connectivity for the same number of devices.
Deployment and complexity
Wi-Fi 6E rewards good planning. You need a heat-mapped site survey, structured cabling to each AP location, and PoE switching. The trade-off is full control: you own the spectrum (it’s unlicensed), the SSIDs, the VLAN segmentation, and the captive portal. Once installed, it just works.
5G is plug-and-play in the truest sense. A 5G router can have your team online in 10 minutes, anywhere there’s carrier coverage. That makes it ideal for:
- Pop-up retail or trade-show stands
- Construction site offices
- Failover when fibre/NBN goes down
- Vehicles and field service teams
- Temporary expansion of existing offices
Security considerations
Wi-Fi 6E mandates WPA3, which closes most of the practical attacks against WPA2 (KRACK, offline dictionary attacks). Combined with VLAN segmentation and an enterprise RADIUS setup, it gives you fine-grained control over who and what is on your network.
5G introduces stronger native encryption than 4G LTE, but the threat model shifts: you’re trusting the carrier’s core network and SIM provisioning. For sensitive workloads, a 5G-to-VPN tunnel back to your office or cloud is essential.
The hybrid approach we recommend
The smartest play for most growing Australian businesses is to deploy both:
- Wi-Fi 6E as the primary indoor network — high speed, low latency, no per-device costs.
- 5G as failover and mobile backbone — via a router with dual-WAN that can fail over automatically when your fibre drops.
- Cellular for IoT and field devices — eftpos terminals, vehicle trackers, environmental sensors.
This setup typically pays for itself the first time your primary internet circuit fails during business hours.
What to buy — our picks for Australian SMEs
For most offices under 50 staff, a Ubiquiti UniFi U6 Enterprise or U7 Pro mesh of three to four access points, paired with a Dream Machine Pro or UDM SE, gives you Wi-Fi 6E performance with a single-pane controller. For 5G failover, a Teltonika RUTX50 or Cradlepoint E3000 handles dual-SIM with carrier-grade reliability.
