What Will “Real” LTE Be Able to Do?

One can argue that “pre-4G” networks, basically all those using protocols that do not yet correspond fully with the official International Telecommunications Union definitions, primarily offer the advantage right now of “more bandwidth” and “lower latency.”
Fully-compliant 4G, which will support a minimum of 1 Gbps for stationary deployments and 100 Mbps for mobile deployments, might have some additional features, though.
The next step in the IMT-Advanced (4G) standards process, in addition to the minimum bandwidth capabilities, will be the ability to maintain and hand off sessions that switch between 4G, 3G and Wi-Fi networks, for example.
While 3G refers to a certain amount of data throughput at certain speeds, 4G is additionally about incorporating multiple standards and interoperable technologies.  In principle, a user should be able to sustain a video conference call and as they move from a LTE-A network to a HSPA environment to a WiFi environment.
Such sessions should be seamlessly handed off from network to network, with the call (or data session) quality dynamically changing based on the network’s capacity to handle the data traffic involved. Though most of the attention will be paid to the bandwidth thresholds, 4G will also mean interoperable and seamless communications across multiple environments.

Verizon Wireless Touts Advantages of LTE

Verizon Wireless Touts Advantages of LTE
Verizon Wireless says consumers will benefit with the implementation of Long Term Evolution in terms of innovative applications developed for healthcare, telematics, cloud-computing, entertainment, utilities, security, education and the machine-to-machine world. That might well happen.
But one suspects it will take a while. In the meantime, 4G is going to offer an experience that is similar to 3G in many ways, but faster, and with lower latency. Verizon says consumers can expect average data rates of 5 Mbps to 12 Mbps downstream, and 2 Mbps to 5 Mbps upstream.
The areas where a noticeable difference should exist is for applications such as video sharing, surveillance, conferencing and streaming in higher definition.
Verizon says coverage “in buildings” also will be better, as will handset battery life.
The user plane latency achieved in LTE is approximately one half that of 3G technologies. This provides a direct service advantage for highly immersive and interactive application environments, such as multiplayer gaming and rich multimedia communications.
Security and roaming also should be easier, eventually, as more networks will use LTE than used GSM. Also, LTE should support machine-to-machine apps better, though that is not something a phone user will know about.
LTE will offer a technically-better platform, no doubt. How long it will take for LTE networks to offer something other than faster speeds, lower latency and better in-building coverage remains to be seen. In the early going, it will be 3G with better performance characteristics, but probably will not have an immediately-perceived value beyond what one expect with a 3G service.
It took quite some time for 3G to create new apps that differentiated it from what 2G networks could do, aside from being “faster.” In fact, it would not be far from the truth to say that it took the “mobile Web” to really create a significant application differentiation from 2G, allowing users to do things they could not do with 2G.
Something like that will happen with 4G and LTE as well.
