 up of representative of telephone companies from all over the world. See Table 7-2 for LTE types. Some are being implemented on shared Wi-Fi spectrum and others are based on high-frequency Gigahertz spectrum. Data on Gigahertz spectrum is able to travel only short distances before fading. However, it supports higher data rates.
