For Ericsson markets t-mobile uses what is known as AIR antenna units which have the radio unit integrated with the antenna. This type of setup significantly reduces signal loss from the radio to the antenna since they're both practically next to each other and not sepearated by coax jumper cables like that of a remote radio unit.
Basic Ericsson AIR21 setup
(Note typically there are 2 Ericsson AIR per sector)
Ericsson AIR21 + Band 12 700 mhz Equipment
Note the addition of a new low band 700 mhz capable antenna + Ericsson RRUS11 B12 (remote radio units) in addition to new TMA (tower mounted amplifiers) connected to the AIR antenna. The new Ericsson RRUS11 B12 + Antenna addition is for tmobiles band 12 700mhz (L700) deployment.

This is the Samsung Outdoor Pico eNB small cell for LTE 1900 that will be deployed by Sprint. Outdoor small cells are utilized to providie additional capacity and coverage mainly in areas where there is a high population density such as major malls, major streets with lot of busineses, train stations, airports, and the like.
Small cells are mostly PnP where you just plug everything in and fire it up and it will auto configure itself by downloading parameters and additional information from the network. Utilizing the latest advances in small cell technology, these pico cells would also over time optimize itself based on feedback from UE and neighboring small cells and macro cells.
Intel modems will never fully catch up to Qualcomm modems because of a few technologies/patents that are exclusive to Qualcomm.
In my opinion, it’s a shame that Apple isn’t exclusively using Qualcomm modems. Qualcomm’s modems outperform their Intel counterparts by about 15% at any given signal level, draw roughly 30% less power, and include a several technologies (which the Intel modems do not) that improve performance by using the assymmetrical paired antennas in the iPhone.
Because Apple thinks that they're asking too much for their patents and that the patents are asking for a percentage of the phone price. The more expensive the phone even if that is due to more memory or bigger screen, the more money Qualcomm makes even though they don't have anything to do with the components that contribute to the additional cost. Qualcomm is mad because they lost out on the half of the LTE modems that Apple is sourcing from Intel and that Apple is not using their processors instead of building their own. As soon as Intel modems catch up to Qualcomm and include CDMA for Sprint/Verizon, I predict Apple will no longer use Qualcomm. It would not surprise me if after CDMA goes completely away Apple does not start making their own LTE/5G modems or acquire a company.
