T/F: Long Term Evolution (LTE) is a wireless communications standard for mobile devices and wireless hotspots. LTE is much faster than the older generation of 2G and 3G cellular networks. Both LTE and its later upgrade, LTE-Advanced (LTE-A), are often marketed as 4G standards.

True

T/F: Multiple Input / Multiple Output (MIMO) is a wireless technology that allows for significant increase in data throughput due to the use of multiple antennas and multiple data streams.

True

T/F: Setting up a wireless network to operate on a non-overlapping channel allows multiple networks to coexist in the same area without causing interference.

True

T/F: The term "Airplane mode" refers to a device function that allows a user to disable wireless transmission capability.

True

T/F: Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) are encryption standards designed for securing wireless networks. WEP is an older standard and is not recommended because of its vulnerabilities. WPA was designed as an interim replacement for WEP, and WPA2 was introduced as the official standard that offers the strongest security of the three.
