I would like website links to recommendations if exist.

There is common solution.
To start with, you may have a misconception about GSM, 3G, 4G:
The frequency bands you checklist are some of the regularity allocations of these sites. These are generally various between various operators plus different nations.
Subsequently: Cellular networking sites aren’t transmitted transmitters. They do not work with constant productivity influence.
The energy they transmit varies according to what they desire to reach. As noted during the opinions above, a cell tower that addresses a massive outlying area will boost down even more electricity per user typically than a small-cell tower in an urban area heart.
Since energy use is amongst the biggest bills in running a cellular network, carriers are extremely into keeping transmit electricity as low as possible.
In addition, reduced maximum transmit power allows for more compact insurance place – this sounds like an anti-feature, but it ensures that the second base place utilising the identical wavelengths may be nearer, which becomes necessary as workers make an effort to provide lots of people in heavily inhabited locations, thereby need to break down these consumers among as many base channels as you are able to, to end up being in theory in a position to provide the collective data rate of the.
Subsequently, as stated, the transmissions is going to be just as strong as required to supply ideal (under some economic concept of “optimal”) services with the subscribers. Meaning: whenever there are only a few devices essentially idling from inside the mobile, the power productivity might be purchases of magnitude not as much as once the network is actually congested and under heavier load.
Lots need a really high active. You can watch an LTE burden monitor from a city middle living right here.
This happens as far as shutting down base station or decreasing the many subbands served at nighttime – some thing we were able to see really nicely take place every night from uni lab in which I spent lots of my weeks (and, demonstrably, far too many nights).
Thus, there can’t be “this is one way a lot electricity all towers emits” quantity, as it will depend on use.
Now, as furthermore talked about, there’s different cellular types. With 3G and 4G, we noticed the 
expansion of micro-, nano- and femtocells. Those are only radioheads which can be located almost anywhere and serve an extremely limited room – as an example, one room.
These obviously would make use of much less electricity than an individual antenna attached to a mast somewhere highest.
Antenna systems can be extremely intricate, as well – today’s base section will make sure to utilize a mixture of antennas to make something such as a ray that hits your own cellphone as precisely as you are able to – desire for this, once again, was much less needed transfer electricity (lower cost) because of not illuminating anyone who’s not into the alert you happen to be obtaining, as well as, risk for denser networks.
Subsequently, there’s factors like interoperability. a service might provide both 2G and 4G, typically closely co-located in spectrum, for a passing fancy mast. Today, arriving the 2G downlink’s electricity too much might lead to saturation in 4G radio (phone) amplifiers – in order to radical decreases in possible 4G rate for a slightly better in 2G high quality.
This problem may get much more vital as operators move to deprecate and turn off 2G, and may in the near future feel generally adjusting schemes in which 2G services are “interweaved” into 4G procedure in the same group (2G is extremely sluggish, and takes only very limited “useful” bandwidth, yet still consumes most priceless regularity groups, so it’s best all-natural to utilize the actual flexible 4G in a manner that states “ok, precious handsets, this might be our usage plan, in which we create holes in time/frequency making sure that 2G can work ‘in between’. Be sure to ignore the content material of these gaps.”). Next, the power/quality trade-off might come to be more complicated.
