The 2.3-2.7 GHz (TDD-LTE) segment spans 2300 to 2700 MHz and is used for tdd-lte / wimax / cbrs edge. Wavelength at the center of this band is roughly 120 mm, which sets the physical size of every resonant element and, with it, the gain a given form factor can reach.
Why the band sets the antenna size
A half-wave dipole at the center of the 2.3-2.7 GHz (TDD-LTE) band is about 60 mm long, and a quarter-wave element about half that. Every practical antenna in this band is a variation on that dimension: a collinear omni stacks several half-wave sections to trade elevation beamwidth for gain, a panel places elements over a reflector, and a Yagi adds parasitic directors ahead of the driven element. There is no way to get more gain out of the same aperture, so a higher gain figure on this band always means a physically larger part.
Above 1 GHz propagation becomes noticeably more line-of-sight dependent. Coverage holds well outdoors with clear sight lines, but each interior wall costs several dB and foliage in the path is a seasonal variable rather than a fixed loss.

Matching the band to the link
Free-space loss at the center of this band is about 100 dB over one kilometer. Add the loss of the feedline, subtract the gain at both ends, and compare the result against the receiver sensitivity for the modulation you intend to run. If the margin is under roughly 10 dB the link will work on a clear day and drop in rain or foliage, which is usually the point at which a higher-gain aperture or a shorter cell radius becomes the cheaper fix.
