5G is coming. The next generation of mobile network technology promises unheralded speeds and connectivity capabilities. With a much faster and more reliable connection on offer, will 5G replace the need for WiFi? Your thoughts about further WiFi development. Thank you!
I personally doubt that 5G will have a major impact on users at the edge, especially in underdeveloped countries where the backhaul to and between ISPs is severely limited. Compared to current wireless technology, 5G networks are expected to increase data throughput by a factor of 10 – bringing multi-gigabit speeds to mobile devices. That means that 5G is well-suited for IoT devices, but it’s far from the most important feature. For the IoT to grow as expected, 5G networks will need to handle far greater device density, and it appears that they can. The 5G specification indicates that 1 million connected devices per .98 square kilometres will be possible, compared with only 2,000 today, and this means that 5G will require the buildout of literally hundreds of thousands of new wireless antennas in neighbourhoods, cities, and towns. A cellular small cell or another transmitter will be placed every two to ten homes according to estimates, and this is not going to come cheap!
As more IoT devices come to market, the strain on the global Internet will become more apparent. So, too, will the relative merits of the varied approaches that have been taken to upgrade global infrastructure. The race is already on. Estimates indicate an expected 125 billion IoT devices to be online by 2030, and current networks are nowhere near ready to accommodate them. In addition, current demand for fibre-optic cable is outstripping supply on the backbone, so it is far from clear if the pace of expansion can even be increased to match the number of devices connected to the access infrastructure. Only time will tell if a combination of upgrades, innovation, and more than a little luck will be enough to sustain the IoT future. If not, we can all look forward to nothing more than a frustrating experience with the BoT—Bottleneck of Things.
wifi is in use for stable and fast local connectivity. 5G is superfast but is weak because of the frequency, one wall, even glassdoor and connectivity isn’t very reliable. Too much dependencies which are not easy to control influence stability. For now no immediate chance the need for wifi is becoming redundant
No, both will co-exist, will need each other and will be part of the same business model.
5G will never replace WiFi - those are very different animals on the market. In fact 5G will boost the sales of MiFis greatly and enable even more WiFi coverage globally.
This debate keeps on morphing on the basis of the “latest and greatest G”; it started with 3G, moved to 4G and now it took on 5G (in a couple of years it will move to 6G ;-)). No technology can completely replace any other technology in a short time span. This is due to what I would call the 3 x A’s viz. Availability, Accessibility, and Affordability. 5G networks will not be available everywhere, they will not be accessible to those without access to 5G devices and the affordability of accessing such networks is still unclear. WiFi on the other hand is available in more locations than 5G will be any time soon, it is more accessible because all data devices (smartphones, feature phones, tablets, laptops etc) come with WiFi modules installed and WiFi is (or is expected to be) free.
Probably that is one of the one million $ questions.
My bet: they will live together for the same subcriber/customer and it will select the best option in every moment. Just as it happens now with 4G (with preferences well activated, of course) .
But… As 5G will always have higher speed than WIFI (and more secure) it will always switch to it, when there is coverage, until the moment in which it gets permanently conected. Then, WIFI will become residual.
Of course It requires a good pricing strategy (flat tarifs) which is going to happen for sure. Not every market will be the same worldwide, of course.
Always think from the point of view of the customer. Of each segment of customers.
But maybe the question is: Fix or mobile?
No, 5G will not replace WiFi in a significant way. Just like WiFi always coexisted with 4G, 3G, and 2G. Network coverage is one reason and connectivity cost / dependency on MNO is another why WiFi will not become obsolete.
They are very likely to coexists but 5G might replace some use-cases.
It is true that 5G offers significant improvements compared to 4G etc. It might therefore replace personal use for convenience in an almost similar manner as mobile phones has replaced fixed phones or laptops has replaced stationary PCs. Hence, the hazzle of setting up public or private WiFi network for this, use of specific password might become absolete.
However, at amount of other connected devices are expected to explode over the coming years in terms of all smart homes, smart cities etc. where WiFi to a large extend will have justification simply due to economies and avoid even the better 5G networks being congested.
5G will become more prevalent outdoors where strong signal WiFi is still difficult to provide.
Technologies evolve I am in the opinion that Wi-Fi by itself will be replaced by other technology:) wait for it . All depend on technical feasibility and value proposition.
In terms of 5G question should be about wired and wireless connectivity at a fixed location like office or home. Fixed wireless access (FWA) is one of the very attractive proposition from 5G it is a type of wireless broadband data communication, which is performed between two fixed locations - connected through fixed wireless access devices and equipment.
Already implemented in few countries and serving the communities. The case studies and business models are attractive , in my opinion it will effect the wired connectivity to a location.
There are two aspects from my point of view:
1) Will “mobile” replace “fixed” with 5G because it’s much faster and has more capacity than 4G?
The answer is “no” - as it was for 3G and 4G. Mobile networks carry just a fraction of traffic compared to fixed line networks and will never be able to catch up with fixed infrastructure.
2) Will 5G replace WiFi in corporate private networks?
The answer is “yes” in some cases. 5G will boost private networks because of frequencies being available and more edge type architecture. This will apply for example to production facilities or any kind of logistics sites.
Are you giving away 5G for free? Is it going to work in tunnels? What about those rural areas where 3G is so absent? The short answer is no it wont. As I understand it there is no 5G solution being proposed that doesnt involve using a paid for network, my wifi does let me connect direct from one machine to another in my home without paying anyone - or maybe more important for some letting my data - outside
