31. Still, some telecommunications analysts point out that MMDS occupies a relatively limited frequency band . 32. More recently, he worked to develop free-electron lasers as power sources in high-frequency bands . 33. Ambitalk addresses this interference by developing a Smart antenna array for low frequency bands . 34. B ) Frequency Band : VHF or UHF, according to the country implementation strategy. 35. Banded waveguides model dispersive behavior by splitting the propagation of disturbances into frequency bands . 36. The resonant cavity is fixed at a frequency in the super high frequency band . 37. Instead, the 2B1Q-encoding used by the frequency band to relocate. 38. Same band repeaters operate with input and output frequencies in the same frequency band . 39. A parametric equalizer does not use fixed frequency bands . 40. They are included here to show the remaining interstices of the 467 MHz frequency band .
