One glaring difference between a 3G and 4G LTE cell tower is that the network coverage or maximum range of 3G or non-VoLTE voice calls and SMS is about 32km while for that of 4G VoLTE voice calls and SMS (plus Internet data) is only 5km(for 800MHz; and only 2km for 2600MHz). From 32km to 5km is a huge difference in terms of coverage for voice calls = more 4G LTE cell towers will be needed to replace one 3G cell tower, especially in suburban, small town and rural areas. For those who mostly make voice calls while travelling outstation and visiting remote stores in rural areas, eg salespersons, the transition from 3G to 4G LTE and 5G will be a problem, ie much less 4G LTE/5G network coverage for VoLTE voice calls.
....... Note that the max range of the slower 3G Internet data is similar to 4G LTE/5G Internet data, depending on the frequency used.
What about 2G.? If 2G is retained when 3G is sunset by MCMC in 2022, then no problem with network coverage for 2G or non-VoLTE voice calls and SMS, but only for those legacy Big 3 celcos who still maintain 2G networks.
....... Latecomer small celcos like U Mobile do not have legacy 2G networks = when 3G is sunset, its subscribers will have to make do with 4G VoLTE voice calls and SMS only, which has much less coverage compared to 3G/2G non-VoLTE voice calls and SMS. The last-comers and newest celcos, YES and TM Unifi Mobile, do not even have their own 3G network, ie they only have 4G LTE networks.

You got any source on that? i wanna read up on it
.https://smallbusiness.chron.com/far-can-cel...gnal-32124.html - How Far Can a Cell Tower Be for a Cellphone to Pick Up the Signal?
Maximum Distance
A typical cellphone has enough power to reach a cell tower up to 45 miles away. Depending on the technology of the cellphone network, the maximum distance may be as low as 22 miles because the signal otherwise takes too long for the highly accurate timing of the cellphone protocol to work reliably. Usually cellphone signals don't reach anywhere near these maximum distances. Typical cell size outside of urban areas means cellphone signals may have to travel up to several miles.
https://en.wikipedia.org/wiki/Cell_site#Range
The maximum range of a mast (where it is not limited by interference with other masts nearby) depends on the same considerations. In any case the limiting factor is the ability of a low-powered personal cell phone to transmit back to the mast. As a rough guide, based on a tall mast and flat terrain, it may be possible to get between 50 and 70 km (30–45 miles). When the terrain is hilly, the maximum distance can vary from as little as 5 kilometres (3.1 mi) to 8 kilometres (5.0 mi) due to encroachment of intermediate objects into the wide center fresnel zone of the signal.[6] Depending on terrain and other circumstances, a GSM Tower can replace between 2 and 50 miles (80 km) of cabling for fixed wireless networks.[7] In addition, some technologies, such as GSM, have an additional absolute maximum range of 35 kilometres (22 mi), which is imposed by technical limitations. CDMA and IDEN have no such limit defined by timing.
This should be the maximum range for 3G voice calls/SMS, not for 3G Internet data, ie a max range of about 35km.
https://opencellid.org/#zoom=17&lat=3.78671&lon=101.85573
Actual cell tower information at Raub, Pahang shows that the range for some 4G LTE cell towers are up to 4km, but most of them are at around 1km range only. This should be the maximum range for 4G LTE Internet data and VoLTE.

Hi Guys,
Aside from the link above, there's some more useful pages on our site for locating nearby 4G towers, as well as an explanation of Telstra 4G, MIMO, and of course using external antennas on the Telstra 4G network.
http://telcoantennas.com.au/site/telstra-4g-explained
http://telcoantennas.com.au/site/locating-telstra-4g-tower
TLDR? range with an external antenna can extend as far as 40km (a number of customers on islands off the coast of QLD), 25-30km over land with good line of sight, but most commonly about 15km for most rural areas. With no external antenna connections are generally limited to 3-7km, hence why coverage maps suggest about 5km.

Sorry for a correction, ie a 2G/3G/4G digital cell tower can serve up to 480 active Internet/voice-calls/SMS users at the same time. Only the 1G analog cell tower can serve up to only 60 active voice-calls/SMS users at the same time.
Please correct the above information if applicable, eg about the max range of a 3G/4G cell tower.
