So, what is LTE? To most, it is a faster network technology. To network operators around the world, it is a way to simplify their infrastructures to reduce costs while improving the quality of their offerings to subscribers. Advertisements by network operators declare it as the “most advanced” network technology. In the end, it is Long Term Evolution of the Universal Mobile Telecommunications System (UMTS).But that doesn’t tell us what LTE actually is.
LTE is what the 3GPP (3rd Generation Partnership Project, the group responsible for standardizing and improving UMTS) designates as their next step. UMTS is the group of standards that define 3G for GSM networks across the world, including AT&T and T-Mobile’s 3G networks. This does not mean a thing to CDMA2000 subscribers, since CDMA2000 is not maintained by the 3GPP. For CDMA2000 subscribers, LTE is the replacement of mediocre CDMA2000 networks offered by Verizon Wireless, Sprint, au by KDDI, and others with a superior cellular telecommunications system offering flexibility and power to the network operator and the subscriber.
LTE is a very good, easily deployable network technology, offering high speeds and low latencies over long distances. For example, the three LTE networks in New York City were rated well. Verizon’s LTE service was rated with an average download speed of 7.67Mbps and an average upload speed of 3.76Mbps. AT&T’s LTE service was rated with an average download speed of 19.21Mbps and an average upload speed of 10.09Mbps. Sprint’s LTE service was rated with an average download speed of 12.35Mbps and an average upload speed of 4.24Mbps. Verizon’s 3G service was rated with an average download speed of 0.47Mbps and an average upload speed of 0.15Mbps. Sprint’s 3G was similarly bad. Similar ratings followed in other cities as well.
I hope this will help...
