Hello everybody,

Mikrotik announced a new miniPCI-e card for LTE/4G named "R11e-4G". It supports some different bands compared to the older card "R11e-LTE". How to decide what card to use at what location? Wondering if it is worth changing/upgrading the cards in my wAP and ltAP.

Both cards support a quite disjunct set of frequency bands. Decission on which one to use should therefore be based on which frequency bands are used by your favourite LTE network operator in the area of deployment. Choosecard that supports prefered band and/or supports more bands.

R11e-4G card is mainly for the new bands that are missing in the R11e-LTE card. The new bands are 31,41,42,43.
Also note that R11e-4G card doesn't support 3G and 2G.

Looks like I will stay with R11e-LTE then.
Anyway... Is there any reliable source what provider uses what bands (other then searching Google...).

Your favourite provider should know that info ... if they don't know it or they don't want to share it with public, you might reconsider your devotion ... In MNOs' defence: things change with continous network roll-out and upgrades so they might be hesitant to give away clear information to avoid being called names after some time when info is not whole truth anymore.
