5G vs Wi-Fi 6E for Business: Which is Best for Your Office?
Compare 5G and Wi-Fi 6E for Australian business networks. Speed, cost, security, deployment time — find the right office network for your team.
Choosing between 5G and Wi-Fi 6E for business is one of the most important infrastructure decisions Australian offices will make this decade. Both technologies promise gigabit speeds, ultra-low latency and improved capacity for dense device environments — but they solve very different problems. If you're planning a 5G office network, designing a new fit-out, or upgrading a tired Wi-Fi 5 deployment, this guide will help you pick the right path (and often, the right blend).
The short answer: it depends on how your team works
For most Australian SMBs and enterprises, Wi-Fi 6E remains the cheapest and fastest in-office network, while private 5G shines for mobile, outdoor, large industrial or mission-critical workloads. The right choice depends on your floor plan, device mix, security posture, and whether your staff actually move around during the day.
What is Wi-Fi 6E?
Wi-Fi 6E extends Wi-Fi 6 (802.11ax) into the newly opened 6 GHz band. In Australia, the ACMA released 500 MHz of 6 GHz spectrum for unlicensed Wi-Fi use, giving up to seven additional 160 MHz channels. The result is dramatically less congestion, multi-gigabit throughput, and sub-2 ms latency for compatible devices.
What is 5G in an office context?
5G can be deployed two ways inside a business: public 5G (Telstra, Optus, TPG carrier services delivered to phones, tablets and 5G routers) or private 5G, where you license dedicated spectrum and run your own small cells. Private 5G is gaining traction for warehouses, hospitals, mines and large campuses where coverage and SLA matter more than cost.
5G vs Wi-Fi 6E: side-by-side comparison
| Factor | Wi-Fi 6E | 5G (private) |
|---|---|---|
| Peak speed | Up to 9.6 Gbps theoretical, 2-3 Gbps real | Up to 10 Gbps theoretical, 1-2 Gbps real |
| Latency | 1-5 ms | 1-10 ms |
| Indoor range per AP/cell | 15-30 m on 6 GHz | 50-150 m |
| Spectrum | Unlicensed (free) | Licensed or shared (paid) |
| Hardware cost (typical 1,000 sqm office) | $5,000 - $15,000 | $50,000 - $250,000+ |
| Ongoing cost | Internet plan only | Spectrum + carrier/MNO fees |
| Deployment time | 1-2 weeks | 2-6 months |
| Security model | WPA3 + 802.1X | SIM-based + carrier-grade encryption |
| Best for | Office desks, meeting rooms, hot-desking | Mobile workers, outdoor yards, IoT at scale |
Speed and capacity in real Australian offices
In our testing across Melbourne and Sydney offices, a modern Wi-Fi 6E access point delivers 1.8-2.4 Gbps to a laptop sitting 5 metres away. A 5G mmWave connection can hit similar numbers, but only with line-of-sight to a small cell. For most floor plates with internal walls, sub-6 GHz 5G drops to 200-600 Mbps — slower than a properly designed Wi-Fi 6E network.
Cost: the deciding factor for most SMBs
A typical 1,000 sqm Australian office can be covered with 4-6 Wi-Fi 6E APs and a managed switch for under $15,000 installed. The same coverage with private 5G easily exceeds $100,000 once you add the small cells, core network, SIMs and integration. Even public 5G routers add $80-$150 per device per month in data fees.
Security comparison
Both technologies are highly secure when configured correctly. 5G has the edge for inherent device authentication via SIM, making it attractive for BYOD and contractor-heavy environments. Wi-Fi 6E with WPA3-Enterprise and 802.1X is essentially equivalent for managed devices and dramatically cheaper to operate.
Deployment: weeks vs months
You can roll out a multi-AP Wi-Fi 6E network in a long weekend. Private 5G typically takes 2-6 months: spectrum application with the ACMA, RF planning, small cell installation, core network commissioning and device SIM provisioning. For most Australian businesses that need network now, Wi-Fi wins on time-to-value.
When to choose 5G
- Large outdoor yards, ports, mines or construction sites
- Warehouses with metal racking that defeats Wi-Fi
- Mission-critical IoT (medical, industrial automation)
- Mobile workforces that need seamless handover beyond the building
When to choose Wi-Fi 6E
- Standard offices, co-working spaces, retail and hospitality
- High device density (60+ devices per AP) with mixed laptops, phones, IoT
- Budget-conscious upgrades from Wi-Fi 5
- Faster file transfers within the LAN (cloud sync, video editing, CAD)
The hybrid approach most businesses actually need
Smart businesses are deploying Wi-Fi 6E indoors and using 5G as failover or for mobile/outdoor coverage. A 5G WAN router gives you carrier-grade backup if your fibre drops, while Wi-Fi 6E handles the everyday traffic. This combination delivers the best uptime and performance for less than going all-in on private 5G.
