11. One product enables operators of transoceanic communications networks to increase the fiber-optic transmission speeds . 12. The service offers several data transmission speed tiers for subscribers. 13. CDPD transmission speed is equivalent to a wired connection using a 14 . 4-kilobyte modem. 14. ADSL stands for asymmetric digital subscriber line, which increases transmission speed in a copper cable. 15. For its transmission speed , RTTY has low spectral efficiency. 16. How can we improve the data transmission speed for minimizing the time lag while talking? 17. Otherwise, transmission speeds will drop to either 28 . 8k or 33 . 6k .) 18. The transmission speed in North America is 9 . 6 kilobits per second, McGinnis said. 19. The transmission speeds required mean that this technology will not come from the current Internet. 20. It is a measure of capacity, not transmission speed .
