41. Longer ( redder ) waves suffer less obstruction but may carry lower data rates . 42. Lower data rates also reduce cost and improve performance when the data is transmitted. 43. Data rates on the bus were theoretically as high as 125 kbit / s.44. Projected data rates and future data rate claims vary. 45. The IBM PC cassette interface encodes data using frequency modulation with a variable data rate . 46. This improves the gain, allowing much improved data rates . 47. The rate is twice the highest data rate previously demonstrated, mission manager Matt Wallace said. 48. Projected data rates and future data rate claims vary. 49. Mardam-Bey, the financier, said he consistently gets data rates well above 500 kilobits per second. 50. Sending a simple e-mail now can take an hour because of the slow data rate .
