Abstract
Background:
Long-term exposure to LTE signals at different frequencies has become a crucial problem in our daily life.

Aim:
The aim of the study to figure out the thermal influence of LTE signals (850 MHz, 1800 MHz, and 2600 MHz) on haematological values in rat’s model during different periods.

Methods:
Forty adult male rats were randomly distributed into four equal groups (control, 850 MHz, 1800 MHz, and 2600 MHz exposure groups). The rats were exposed for 2 hours per day over a period of up to 60 days using a radiofrequency generator.

Results:
The results showed that the different frequencies have different effect on both haematological and thermo-graphical image analysis.

Conclusion:
The study findings demonstrate that these LTE frequencies have a detrimental effect on the rat model through thermal mechanisms.
