Many people would think that 4G and 4G LTE network is one,but absolutely not. The 4G network provides that when using smart phones to access the internet at speeds of 1Gbps (fixed) or 100Mbps (when moving quickly) to be considered 4G network standard. And 4G LTE (Long-Term Evolution) is a wireless standard higher than 3G but not with 4G. If your device does not achieve the above-mentioned threshold speed, which is higher than the 3G network, your network is only 4G LTE only.

However, 4G LTE network still offers faster transfer speeds than 3G, so you can still satisfied with the device only supports 4G LTE for 4G LTE network is currently considered the standard network connection current fastest wire without a net, device meets 4G standards.
