Tire speed rating tells you the maximum service speed for a tire. A speed rating isn't, however, a recommendation to exceed speed limits, and doesn't indicate how well a tire handles or corners. The speed rating tells you the maximum speed capability of the tire when properly inflated.
LTE (telecommunication) Long-term evolution redirects here. For the biological concept, see Evolution and E. coli long-term evolution experiment. In telecommunication, Long-Term Evolution (LTE) is a standard for high-speed wireless communication for mobile phones and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements.
For a number of reasons, enabling voice calling over LTE is not so simple as just using a VOIP connection. Carriers need to be able to pass or hand off voice calls, without interruption, between the LTE networks and the legacy 2G and 3G networks.
