Enterprises can now connect people and devices in three distinct ways: Wi-Fi 6/7 inside buildings, laptops with built-in 5G modems, and private 5G networks for operational sites. Comparisons usually focus on peak speed, yet the three follow very different cost curves, and those curves say far more about where each one fits.
All three technologies are maturing at the same time. Cisco describes Wi-Fi 7 adding Multi-Link Operation across bands, 320 MHz channels and 4096-QAM.[1] Dell and Microsoft now sell business laptops with factory-fitted 4G/5G modems and eSIM support.[2][3] In the US, the CBRS band makes 150 MHz of spectrum available for commercial use on a shared basis, which enterprises can use for private cellular networks.[4]
Headline speeds are a weak basis for choosing between them. Cisco notes that the highest Wi-Fi 7 data rates need a signal-to-noise ratio above roughly 43 dB, so only clients close to the access point benefit.[1] Cost structure is more decisive. Wi-Fi is a shared building investment on unlicensed spectrum. A 5G laptop carries a recurring per-device plan, with Dell’s US carrier offers starting around US$20 a month.[2] Private 5G is a site-level project involving radios, a cellular core and spectrum access. How each of these costs grows as an organisation grows is what really separates them.
This post compares the three on that basis, starting with Wi-Fi, the benchmark the other two have to beat.
Wi-Fi Economics: One Shared Network, a Falling Cost per User
Wi-Fi is the benchmark every other option has to beat, so it is worth being clear about how its costs behave. An enterprise Wi-Fi network is a shared investment. You pay for access points, licences, switching, cabling and installation largely according to the size and layout of the building, and then everyone inside uses it. Cisco’s Wi-Fi 7 design guide puts typical enterprise density at roughly one access point per 1,000 to 2,000 square feet.[1]
That has a powerful consequence: the more people and devices share the network, the lower the cost per user. Wi-Fi also runs on unlicensed spectrum. Wi-Fi 6E and Wi-Fi 7 use between 500 and 1,200 MHz in the 6 GHz band with no spectrum fees, whereas mobile operators pay heavily for licensed bands.[1] There is no per-device subscription; a new laptop, phone or meeting-room screen joins at almost no marginal cost.
Wi-Fi is not free, of course. Refresh cycles bring hidden costs: Cisco recommends planning for 60 W PoE switch ports and faster multigigabit uplinks for current access points, so a Wi-Fi 7 upgrade often means a switching upgrade too.[1] And the building still needs internet or WAN circuits behind the wireless network. Even so, the curve is the important part.
A 5G laptop works the other way. Each activated device carries its own monthly plan, so the cost per user stays flat however many people you connect, and the total grows in a straight line with every activation. Private 5G sits apart again: a site-level project whose cost depends on area, devices and integration rather than headcount.
The useful question is therefore not which technology is “best”, but which combination connects people and operations reliably at a sensible lifecycle cost. That depends on three things: where the work happens, whether the people or equipment move, and how the cost grows as the organisation grows.
The three options at a glance
In plain terms: Wi-Fi is like the building’s plumbing, installed once and used by everyone. A 5G laptop is like giving an employee a company phone contract for their computer. Private 5G is like building your own small mobile operator for a site.
Side-by-side comparison
Here is how the three compare across the factors that drive cost, risk and day-to-day operations.
| Factor | Wi-Fi 6 / 6E / 7 | Laptop 5G WWAN | Private 5G / CBRS |
|---|---|---|---|
| What it is | Enterprise wireless LAN inside your buildings | Cellular modem and SIM/eSIM in the laptop, using a public mobile network | Your own cellular network for a defined site |
| Who runs the network | Your IT team | The mobile operator | Your IT/OT team or a managed partner |
| Spectrum | Unlicensed 2.4, 5 and 6 GHz; 500–1,200 MHz of 6 GHz with no spectrum fees[1] | Operator’s licensed spectrum, included in the plan | Shared or local licences, e.g. US CBRS: 150 MHz at 3,550–3,700 MHz shared with federal users[4] |
| Where it works | Inside covered buildings | Anywhere with mobile coverage | Inside the private network’s footprint |
| Devices | Almost every laptop, phone and tablet | WWAN-equipped laptops only[2][3] | Devices that support the right bands and SIMs |
| How users are identified | 802.1X / WPA3 credentials | Operator SIM; enterprise access still via VPN or zero trust | Enterprise-controlled SIMs |
| Cost model | Shared, mostly upfront plus support | Monthly plan per activated laptop | Project: radios, core, spectrum, SIMs, integration, operations |
| Cost grows with | Floor area and density | Number of activated laptops | Site size, device count, integration |
| Time to deploy | Weeks per site (survey, cabling, install) | Days: activate a plan | Months: design, spectrum, proof of concept |
| Strongest fit | Offices, labs, meeting rooms, guests | Field, sales and travelling staff | Large sites with moving equipment and strict uptime needs |
| Poor fit | Work outside the building | Desk-based staff on known networks | General office access |
Wi-Fi 6, 6E and 7: what actually changed
Each generation adds capacity rather than changing the economics. Wi-Fi 6 introduced OFDMA to share airtime more efficiently; Wi-Fi 6E opened the 6 GHz band; Wi-Fi 7 adds Multi-Link Operation across bands, 320 MHz channels and 4096-QAM.[1] As noted earlier, the highest Wi-Fi 7 rates need a very strong signal close to the access point, and Cisco also notes that simply swapping old access points for new ones in the same places rarely fixes existing coverage or roaming problems.[1]
Where the money goes: Wi-Fi vs 5G laptops
Wi-Fi and laptop 5G are the two options most organisations will actually weigh against each other for staff connectivity, so they deserve a direct cost comparison. Private 5G is also included as an indicative range, so all three sit in the same model.
As covered above, Wi-Fi’s cost is shared across everyone in the building. Laptop 5G is priced per device: Dell’s US connected-PC page advertises promotional carrier laptop plans from around US$20 per month (Verizon) and US$25 per month (AT&T).[2] Enterprise agreements, other countries and roaming will differ.
With or without 5G: the laptop hardware premium
Before any plan is activated, a 5G laptop already costs more to buy. Published prices give a reasonable sense of the premium:
| Example | Without 5G | With 5G | Premium |
|---|---|---|---|
| Microsoft Surface Laptop for Business 13.8" (Intel), entry configuration | ≈ $1,500 | $1,799.99 | ≈ $300[5] |
| Lenovo ThinkPad X1 2-in-1 (Gen 10), factory 5G modem option | Base price | Base + modem | ≈ $200[6] |
| Lenovo ThinkPad 5G module bought as an upgrade (WWAN-ready models only) | – | $292.99 module | ≈ $290[7] |
The model below therefore uses US$250 per laptop as a mid-point. Two practical points matter more than the exact figure. First, a laptop generally has to be ordered “WWAN-ready”, with the right antennas, to take a modem later; retrofitting a standard model is rarely possible. Second, Dell notes that 5G can draw more power, so battery life is worth checking on the models you shortlist.[2]
The hardware premium turns out to be the smallest part of the 5G decision. Over five years the plan costs around five times more than the modem. That suggests a sensible middle path for roles that might need cellular: buy WWAN-ready or 5G-equipped hardware for them, but only activate a plan, ideally via eSIM, when the need is real.
Will 5G laptop plans get cheaper?
It is tempting to assume cellular plans will keep falling in price and close the gap with Wi-Fi. The evidence is mixed. Cable.co.uk’s 2023 global study put the average price of 1 GB of mobile data at US$2.59, and found US prices per GB had more than halved since 2019, although the US still sat well above the global average.[8] The analyst behind that study also noted that much of the improvement reflects more data being offered for similar money, rather than lower bills.[8] Industry analyst Tefficient similarly reports that mobile revenue per gigabyte keeps declining, but more slowly than before.[9]
Monthly per-line prices have not followed the per-GB curve down. In 2024, for example, Verizon and AT&T raised prices on some older unlimited plans.[10] The more realistic expectation is more data per dollar, not a much lower monthly price per laptop, and plan budgets on today’s rates. Even if plans halved to US$10 a month, a fully loaded 5G laptop in the model below would still cost about US$19.70 per month, around three times shared Wi-Fi.
A plan price or an access-point price on its own understates the real cost, so the model below adds the items that are usually left out: the office internet circuits Wi-Fi depends on, the laptop modem premium, roaming and overage, plan management, and a 15% contingency buffer on every option. These are planning assumptions based on reference values, not quotes; substitute your own numbers.
| Assumption | Value |
|---|---|
| Office floor area / headcount | 100,000 sq ft (about 9,300 m²), 1,000 employees |
| Wi-Fi design density | 1 access point per 1,500 sq ft, giving about 67 APs |
| Wi-Fi five-year cost per AP (hardware, licence/support, PoE port share, cabling, installation) | US$3,000 |
| Added: office internet, two diverse circuits | US$2,500 per month combined |
| Laptop 5G plan | US$20 per laptop per month |
| Added: WWAN modem option on the laptop | US$250 one-time per laptop (see hardware premium above) |
| Added: roaming and overage buffer | 10% of plan cost |
| Added: plan management and support | US$2 per laptop per month |
| Genuinely mobile staff | 15% of employees (150 people) |
| Added: contingency buffer | 15% on every option |
| Period | 5 years |
| Five-year cost build-up | A. Wi-Fi only | B. Wi-Fi + 5G for 150 mobile staff | C. Wi-Fi + 5G on all 1,000 laptops |
|---|---|---|---|
| Wi-Fi infrastructure (67 APs) | $201,000 | $201,000 | $201,000 |
| Office internet circuits | $150,000 | $150,000 | $150,000 |
| Laptop 5G plans | – | $180,000 | $1,200,000 |
| WWAN modem option | – | $37,500 | $250,000 |
| Roaming and overage buffer | – | $18,000 | $120,000 |
| Plan management and support | – | $18,000 | $120,000 |
| 15% contingency | $52,650 | $90,675 | $306,150 |
| Five-year total | $403,650 | $695,175 | $2,347,150 |
Even with the internet circuits added to Wi-Fi, the gap stays wide. Fully loaded, Wi-Fi works out at about US$6.70 per user per month in this scenario, while each 5G laptop costs about US$32.40 per month, nearly five times more. Turning 5G on for everyone also does not remove the need for office Wi-Fi, because phones, guests, meeting rooms and building systems still depend on it, so you end up paying for both. Targeting the 15% who genuinely work on the move saves about US$1.65 million over five years compared with enabling it everywhere.
Private 5G does not slot neatly into a per-user comparison, because it connects devices and machines on one site rather than people wherever they are. It is shown here as a range. For a single 100,000 sq ft site indicative planning assumptions are radios and installation of US$40,000–100,000, a cellular core, SAS and management subscription of US$15,000–40,000 a year, design and integration of US$50,000–150,000, and operations or managed service of US$20,000–60,000 a year. Over five years, with the same 15% contingency, that is roughly US$0.3–0.9 million, before any device or gateway upgrades. Real quotes vary widely by vendor, country and spectrum model, so treat this as a sense of scale only.
Who should get a 5G laptop?
The hidden costs matter as much as the plan price: international roaming, activating and cancelling plans as people join and leave, plans that keep billing after a role changes, and helpdesk effort for carrier issues. A SIM also only proves the laptop may use the mobile network; it does not grant access to company applications, so VPN or zero-trust access is still required.
Private 5G and CBRS: a specialist tool
Private 5G is not an alternative to Wi-Fi for office staff or to 5G laptops for travellers. It is an operational investment for sites where devices move continuously and dropped connections stop work.
Lufthansa Cargo’s LAX warehouse is a good illustration. Ericsson reports that two private 5G radios now cover a facility previously served by 17 Wi-Fi access points, and that scanner-driven process speed improved by 70–80%.[11] Those are vendor-published, customer-reported results, and the case study does not disclose comparable costs. “Two radios instead of seventeen” describes coverage, not total cost; a private network adds a cellular core, SIM management, spectrum arrangements and specialist operations.
Spectrum is the other gating factor. CBRS is a US framework that shares 150 MHz between 3,550 and 3,700 MHz with federal incumbents under a three-tier model, with access managed by certified Spectrum Access Systems.[4] It is not available globally. Organisations operating in India, Europe or elsewhere need a country-by-country view of local licensing before any design work starts.
What about 5G routers at branches?
A 5G router at a branch is a fourth, separate use of cellular. It works well in two roles: as the main link for a small site, and as a backup when the primary WAN fails at a larger office.
GAIL’s Bakery trialled 5G routers at ten UK sites before extending them to another 80, citing services available from day one without waiting for a fixed line.[12] DiPasqua Enterprises, a Subway franchisee with around 100 restaurants, runs more than 15% of locations on cellular alone and reports 20% lower operating expenses from consolidating equipment and subscriptions.[13] Both are small-footprint sites. For a large office, keep 5G as a tested failover path and size its data plan for a multi-day outage.
The decision in one table
| If the need is… | Choose | Why |
|---|---|---|
| Staff connectivity inside offices and labs | Wi-Fi 6E / 7 | Lowest cost per user; works with every device |
| Productive work at customer sites and while travelling | 5G laptops for those roles only | Pays back for mobile roles; wasteful for desk-based staff |
| Small shop, kiosk or pop-up site | Branch 5G router as primary link | Live from day one; no circuit wait |
| Keeping a large office online when the circuit fails | Branch 5G as backup | Diverse path for priority applications |
| Moving equipment across a large operational site | Evaluate private 5G alongside Wi-Fi | Mobility and control, if spectrum and value are proven |
The bottom line
Wi-Fi 6/7, 5G laptops and private 5G are complements, not competitors. Buildings get Wi-Fi. Mobile people get 5G laptops, chosen by role. Moving machines on large sites may justify private 5G once Wi-Fi has been assessed and the business case is measured.
Giving each technology a clear job, and pricing it on the right cost curve with a realistic buffer, typically costs less and delivers more reliable connectivity than chasing whichever option is newest.
