If D is a lot less than zero, the medium is claimed to get constructive dispersion or typical dispersion. If D is greater than zero, the medium has unfavorable dispersion. If a light pulse is propagated through a Usually dispersive medium, the result is the upper frequency elements decelerate much more than the reduced frequency factors. The pulse as a result turns into positively chirped, or up-chirped, escalating in frequency with time.

4 and a pair of.83 GHz within the from this source ISM band. This allows Bluetooth networks to work in the presence of sounds, other wireless products together with other Bluetooth networks utilizing the same frequencies, due to the fact the possibility of One more machine trying to transmit over the same frequency for the same time as the Bluetooth modem is low. In the situation of such a "collision", the Bluetooth modem just retransmits the information packet on another frequency.[113]
