> Along the way, five towers and nine cells (a.k.a eNB for Evolved NodeB) What does this mean? Whats the diff between tower and cell?

He explains this two sentences later: >- Several cellIDs map to the same eNB lat/long coordinates. That's because the antennas mounted on an eNB don't have 360° coverage. The angle and range of each antenna carves the space into pizza slice shaped cells.

It's explained in the article, one tower can have multiple antennas (author found out they're typically set at 120°) on a single mast. Each antenna is then a cell, altough mounted on a single tower.

  Ah multiple antennas. Makes sense. Thanks!

Towers are just locations of at least one set of sender and receiver. There can be more than one set of these at a given location, meaning that more than one cell can originate from a single tower. The first graphic visualizes this. Recption of the same cell is indicated by the same color there, while towers are at the points that these colored cones radiate from. Several cones of different colors start at the same points, visualizing that there are towers that are providing more than one cell. Observe that the reception can jump back and forth between the same cells as can be seen on the brown and blue colored cells in the top left corner of the graphic.

it gets even more fun when you throw in beamforming. a tower is just a mast on which radios are mounted. a site is the location of the equipment. a node is the name for a set of radios and base systems. a nodes service can be divided in to sectors. a cell is usually a certain coverage area served, the frequency of cells will differ a bit from it's neighbor to stop interface. and a beam is specific focused radio that serves one UE.

> Whats the diff between tower and cell? The tower is what it sounds like, it is one physical structure containing the communications equipment, also called a Base Transceiver Station (BTS) [1]. The cell is the individual communications panel on the tower, also known as a CellID [2]. There are typically 3 panels on a tower, each covering 1/3rd of the surrounding area. So the tower gives you the physical location, and the cell gives you the general direction.
