Do we even need 5G at all? So why is it more of a nightmare? The promise of faster bandwidth At least on paper, everything about 5G makes sense.

Why 4g is popular and what consumers need to know

By Neal Gompa on April 1, at Now, nearly all cellular-enabled devices sold today support LTE for 4G service — sometimes even without 2G or 3G technologies supported.

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.

For subscribers to operators with networks utilizing CDMA technology, LTE is the replacement of mediocre CDMA networks with a superior cellular telecommunications system offering flexibility and power to the network operator and the subscriber.

But to get the complete picture, reading the whole article is advised. The current specification outlines the following bandwidth blocks: Frequency bandwidth blocks are essentially the amount of space a network operator dedicates to a network.

Depending on the type of LTE being deployed, these bandwidths have slightly different meaning in terms of capacity. That will be covered later, though. MetroPCS was an example of a network operator that has done this.

There were a few markets with 5MHz deployed, but these were the exception, not the rule. Additionally, neither operator had enough backhaul the core network infrastructure and connections to the internet dedicated to LTE to make larger bandwidths worth it either. Of course, these issues went away when they were acquired.

On the other hand, Verizon Wireless has been using 10MHz wide channels for LTE all across the board for MHz, since it has the national allocation of spectrum available for it.

Combined with excellent backhaul, LTE service from those two companies promise to be best in class. Sprint has a similar problem, as its main network is a singular 5MHz channel nationally.

LTE can support up to active data clients smartphones, tablets, USB modems, mobile hotspots, etc. That means that if a particular tower has 20MHz of spectrum allocated to it, it can support up to data clients at full speed.

There are ways of supporting more data clients per 5MHz, but doing so requires sacrificing speed and capacity, as the per-5MHz ratio is the optimal configuration. How LTE actually works LTE uses two different types of air interfaces radio linksone for downlink from tower to deviceand one for uplink from device to tower.

By using different types of interfaces for the downlink and uplink, LTE utilizes the optimal way to do wireless connections both ways, which makes a better-optimized network and better battery life on LTE devices.

What does this mean? Having MIMO means that devices have multiple connections to a single cell, which increases the stability of the connection and reduces latency tremendously.

It also increases the total throughput of a connection. MIMO is what lets There is a significant disadvantage though. MIMO works better the further apart the individual carrier antennae are. On smaller phones, the noise caused by the antennae being so close to each other will cause LTE performance to drop.

The LTE technology itself also comes in two flavors: The most common variant being used is the FDD variant. The FDD variant uses separate frequencies for downlink and uplink in the form of a band pair. That means for every band that a phone supports, it actually uses two frequency ranges.

These are known as paired frequency bands. Some will also call it a 20MHz network, but this can be ambiguous. The TDD variant uses one single range of frequencies in a frequency band, but that band is segmented to support transmit and receive signals in a single frequency range.

Everyone else is deploying in the FDD variant. Fortunately, LTE devices can easily be made to support both variants on a device without too much trouble.Why use cheap consumer tech like Wi-Fi when you can use an industrial-grade protocol like 4G LTE?

Remember, connectivity could make or break the success of your products and services.


Dont take this choice lightly, and make sure you understand the future use of . On Tuesday, Apple announced the iPhone 5S (and iPhone 5C), giving us a look at one of the more significant “S” upgrades we’ve seen from them. A faster processor, new camera tech, a revamped.

Femtocells are popular with customers for a number of reasons. With a femtocell, users receive maximum signal coverage in an area up to 2, square feet. The strong signal results in higher quality voice reception, increased data speeds, and less dropped calls. For those reading this article who don’t know what that means, ask your parents.

Mr Negroponte’s beautifully simple statement sums up why organisations increasingly need to evolve their strategy and business model to be successful in today’s constantly changing world.

In the world of mobile phones, there are two primary phone types that are available to consumers: GSM (Global System for Mobile) and CDMA (Code Division Multiple Access). GSM phones are the ones that utilize SIM cards while CDMA phones do not. SIM cards are the small cards which contains a chip that.

However, it’s more than likely you’ll need to invest in a new 4G-enabled device to take advantage – and these start from around £ “Being an entry-level offer, the data allowance with the £ monthly contract isn’t hugely generous.
