Cell Phone Reviews


Maintenant nous avons tous entendu sur comment chaque cellulaire transporteur est superbe à l'autre et ils font un excellent travail à promouvoir leur – croyances constamment diffusion de spots publicitaires, achat de présence sur le web et saturer toutes les formes de médias, nous savons tous comment Verizon, Sprint, AT & t et T-Mobile ont la meilleure couverture et une vitesse plus rapide autour de tous. Malheureusement, il y a un certain nombre de facteurs différents qui vont déterminer quel réseau est le meilleur pour qui, y compris ce qu'ils peuvent de téléphone ont, où ils vivent et ce qu'ils utilisent leurs téléphones pour sur une base quotidienne.

Both Verizon and AT&T, the two largest cell phone carriers in the US, have been bragging especially loudly recently due to the unveiling of their 4G LTE networks that claim to increase network speeds by an enormous amount when compared to traditional 3G infrastructure. Même si LTE (abréviation de Long terme évolution) est essentiellement une technologie standard et finalement conduit à une norme mondiale dans lequel chaque transporteur s'exécute sur les réseaux identiques, nos systèmes actuels sont au rattrapage à cette tendance et donc encore auront quelques différences. Quelles sont exactement les différences entre les technologies des giants de deux cellules en ce moment et ce que cela signifie pour vous ?

Verizon's LTE Network

One of the biggest misconceptions about Verizon's 4G LTE network is that it is, in fact, a 4G network. While Verizon has made serious upgrades to its network over the past year, the standards of 3GPP LTE are that of, well, take a look at the first two characters of '3GPP'. However, in the near future Verizon will have a truly-compliant 4G network due to newer releases of LTE (LTE Advanced) which will be applied more like a software patch than a complete renovation of physical infrastructure.

This is not to say that Verizon's network is not much faster with the new LTE technology. Reliable, consistent speed averages from various major metropolitan areas show an increase of 1000% when compared to the 3G infrastructure. These are huge accomplishments considering that LTE technology can only be integrated into existing networks that use GSM/EDGE (AT&T, T-Mobile); Verizon had to build its existing LTE infrastructure from scratch due to its past reliance on CDMA technology.

AT&T's LTE Network

Similar to Verizon, AT&T's network is also only 3G in name but much like its counterpart, it will have an actual 4G LTE system in place in the coming years when upgrades to the technology are made. AT&T's version of “4G” is a combination of HSPA & LTE technologies that allow for an increased amount of traffic to flow at faster rates. Whereas Verizon's 3G technology (CDMA) est incompatible avec son LTE réseau de AT & t GSM la technologie est construite à utiliser LTE et permet à 4 G /LTE pour fonctionner sur les téléphones plus anciens GSM technologies.

Essentiellement, les téléphones 4 G sont capables d'utiliser les LTE technology on AT&T's network for the majority of the data transfer but can also utilize HSPA in combination to increase the overall speed at which pages and files download. Generally speaking, this leads to faster download rates but can vary depending on the strength of your connection, the backbone of the network in your area and the phone you are using. For example, while 4G/LTE peuvent utiliser les téléphones 3G (HSPA), la technologie 3G les téléphones ne bénéficient pas de la LTE network.

Avantages et inconvénients de Verizon

Based on nationwide averages, Verizon has the fastest network overall. Its newly-constructed LTE le réseau est isolé du reste du transporteur 3G traffic and that leads to more bandwidth for each user to enjoy. If you live in a medium-to-large city, you can expect great results with this carrier and will probably see download speeds in excess of 7 times faster than traditional 3G speeds.

Verizon's network has some downsides as well, such as not being able to utilize its 3G technologie et le réseau en collaboration avec ses LTE service. What this means for the average user is when he or she leaves (or does not live near) a major metropolitan area, there is a greater chance that the overall speed of the network will decrease substantially (and in many cases, drop down to 3G). Verizon a également une aire inférieure de LTE due to its newly-created infrastructure that does not yet cover the entire country as well as AT&T's.

Avantages et inconvénients à AT & t

AT&T's network utilizes the best of both worlds and any 4G/LTE Téléphone peut utiliser les deux LTE & HSPA at the same time, leading to an overall faster experience with both upload and download speeds. In some of the biggest cities, AT&T's data speeds blow Verizon out of the water due to this effect. Since AT&T's entire network is GSM and therefore fairly easily upgraded when future versions of LTE deviennent disponibles, il est susceptible de contenir une edge en termes de LTE coverage and speed in large areas for quite some time.

While AT&T's data network covers a greater percentage of the populace, its LTE service is not as widely available as Verizon's. Since AT&T has been able to “upgrade as they go”, they have not been nearly as motivated as Verizon to unveil it across its entire network. When it comes to rural areas, AT&T LTE est pratiquement inexistante.

Le Verdict

Here is a video we put together to demonstrate the differences in download and upload speed on AT&T and Verizon. The video was shot in a suburb of Philadelphia.

Dans ce cas, Verizon a été plus rapide. Cependant, il s'agit vers le bas à votre situation particulière. Si vous habitez dans l'une des grandes villes (New York, Los Angeles, Houston, Chicago, Philadelphie), AT & t sont votre meilleur choix ; ils ont une couverture supérieure et une vitesse plus rapide dans pratiquement chaque test. Si vous résidez dans une ville plus petite mais toujours grande (San Francisco, Atlanta, Dallas, Boston), Verizon sera probablement battu à AT & du t réseau de zone de liste déroulante en raison de son infrastructure nouvellement construits et l'absence de partage de bande passante avec 3G traffic. The same goes for those living in large suburban areas or medium-sized towns; Verizon has a better game. Lastly, for anyone dwelling in rural areas, AT&T tends to have better coverage overall but has a weaker LTE présence.
