In the review they say Antennas are sized to be fractions of full wavelengths. I thought I read a year ago that the reason the 4 and 4s didn't have LTE was because the physical size of the phone wasn't large enough for the radio antenna needed for LTE. Is it true that they needed to extend the size of the phone to get the right fractional size for an LTE antenna?
- jgrahamc 14y agoIn the US the lower frequencies being used for LTE are 700/800 MHz which corresponds to a wavelength of between 37 and 43 cm. A dipole would be at 1/2 wavelength or 21 cm at the lowest frequency. At 1/4 wavelength you'd be looking at 10 cm long. The iPhone 4S is 11.5 cm long so I think that a 4G/LTE antenna would fit inside just fine.
