The Samsung 4G LTE Mobile Hotspot uses the Qualcomm MDM9600 chipset, and it supports Verizon’s 4G LTE 700MHz band as well as CDMA 3G EV-DO Rev. A and Rev. 0 on the 800/1900MHz bands. When you are in areas without 4G LTE coverage, the Mobile Hotspot will fall back to 3G EV-DO. The Samsung SCH-LC11 Mobile Hotspot works with devices and computers with WiFi 802.11b/g/n and it can support up to 5 devices at a time.
