question regarding the green boxes in the neighborhood

[wireless]

Hi, we are trying to buy a house and have found a couple of green boxes with the Telus name on them. Those boxes are located literally on the lot area (backyard) but still outside the fence. We are concern about the boxes: what is the purpose of those? Are they safe to live nearby or not? Is there any magnetic field (wavelength) that can be potentially dangerous from them. Are they noisy and huge? Curious if someone has any idea about it. Appreciate every feedback.
