Mobile Technology G, E, 3G, 3G +, H, H + or 4G BD ~ LTE 4G

Those who use a smartphone ( especially those who do it for the first time ) at some time have wondered who those letters ( G, E, 3G, 3G +, H, H + or 4G ) displayed next to the time in top, which also shows other information such as call coverage, time, battery, etc ...

Technology

Provided we have a contracted data rate to an operator, depending on several factors that will be explained later, we will be connected through a technology specific, that will affect us in two main ways:

Internet browsing speed:

Each technology allows a maximum "flow" of discharge ( see websites, youtube videos, check our Twitter, etc ... ) and upload ( send messages or photos by WhatsApp, post messages on social networks, etc ... ) of information. When we talk about speed in this article, we refer to this. 

Consumption and battery life 

Each technology requires consumption of battery different, consuming more operating in the higher frequency band  ( 3G or GPRS  for example ).

We will explain what each one means and maximum speeds at which they work, to understand it easily. 

NOTE : The maximum speeds are specified in Kbps or Mbps ( bits ), to pass on to KB / s or MB / s ( bytes ) we must divide by 8, or use the Google converter kbps . Learn more.

1. GPRS

When we listed G, means that we are connected by GPRS, the slowest of the range of possible technologies offered data rates of our operators. It is, usually, considered a network 2.5G, a network 2G ( second generation ).

This technology is similar to the old modems 56k that were used in the 90s with flat data rate Internet. Although it is quite slow, you can use to send and receive text messages via apps like GTalk, Whatsapp or LINE without getting desperate.

GPRS

It, usually, occurs in places with little mobile coverage, garages, basements, Zulus Sysadmin or lifts to which mysteriously do not lose the signal completely. 

Theoretical maximum speeds that can reach GPRS are 56 ~ 114kbps ( about 7 ~ 14 KB / s ).

2. EDGE 

If we listed E we will be connected via EDGE ( EGRPS ), an enhanced version of GPRS. Network is often called 2.75G or 2.8G ( although not official name ), since, depending on the implementation of the operator, it can reach speeds of a network 2G or a network 3G.

EDGE

Some users use apps like Data on Demand to establish these slow networks while having a locked phone ( unused ). Once unlocked, you regain the high-speed connectivity. It is useful for those who do not need to use high velocities and want to conserve the most from your battery. 

The theoretical maximum speed of EDGE is, usually, around 384kbps ( about 48 KB / s ), however, rarely tend to achieve these values. Still a slow network, like the previous one.

3. 3G

Called 3G ( third generation ) to use technology UMTS, designed for high-speed data transfers, useful for multimedia content. 

Today is often called 3G data rate to any high speed, however, it is more common to use other faster technologies such as HSPA + that most people continue terming 3G.

3G UMTS

This type of technology allows more and decent use of the Internet, such as sending mail or view Web pages. However, it is not the fastest. The speed of 3G networks exceed the maximum limit of 384kbps and can reach up to 2Mbps in good condition.

4. HSPA / 3G + 

Within the scope of the technology represented by the letter, H is HSPA, which is only the combination of HSDPA ( download ) and HSUPA ( upload ). In Bangladesh, some operators such as Orange are the icon 3G +, which although not exactly equal to H, for practical 

HSPA / 3G +

This technology is capable of download speeds of 14.4Mbps, much higher than those seen so far. The slew rate can range from 386kbps to 5.76Mbps, depending on whether or not the operator implements HSUPA. Generally, it is more than enough connection for most users.

5. HSPA + 

Icon H + represents the technology HSPA + ( evolved HSPA ), which substantially improves the speed of downloading and uploading over their predecessors. It is often referred ++ 3G or 3.8G .

HSPA + 

The flow of theoretical maximum speed of 84Mbps ( discharge ) and 22Mbps ( rising ), although, as always, it depends on the implementation by the operators.

6. 4G 

Finally, swifter list technology is called LTE, considered 4G ( fourth generation ). In early 2013, forecasts to have LTE in Bangladesh are still quite poor, but there are many preparations and mobile devices to support this technology.

4G LTE

Powered LTE, the flow high speed reaches up to 100Mbps ( download ) and 50 Mbps ( upload ), and even get to 1Gbps for users who need low movability. For its part, the evolution of WiMax ( also considered a network 4G ) can reach 128Mbps ( download ) and 56Mbps ( rising ).

7. WiFi 

Networks WiFi does not belong to the group of technologies that provides a data plan, but connection points are established by individuals ( or companies ) which in turn ( and generally ) have hired an Internet connection. Thus, a network access has a certain speed, depending on the plan that has contracted Internet owner ( including WiFi networks are used to interconnect systems without Internet ). Also be careful, because connect to a WiFi network could have security implications, such as capturing a user traffic ( data or passwords ).

WiFi

Another detail which little has been said so far is the battery consumption. Now that we know the types of technology available, we will discuss the optimal conditions for us that our battery life as much as possible:

Maximize Battery.

2G technologies such as GPRS or EDGE are great for when we have little activity on the Internet, as they hardly consume data. For example, a mobile locked, only use it to receive messages in WhatsApp and LINE.
Technologies 3G / 4G become better when we have to transmit data heavy, as high-resolution photographs, watch videos on Youtube or upload a site with many pictures:

Maximize Battery

Remember also that the continuous scan networks looking for better coverage and 3G or WiFi can drain your battery quickly. If you're in an area with poor coverage and are not using your mobile, it is preferable to uncheck the data from your smartphone.

Why 's it going so slow mobile Internet?

Important: The speeds specified above are theoretical values,b ut the actual values depend on several factors. The main ones which I quote below:

• Moving boundary : Our mobile can not support a type of technology. For example, in late 2012 was not common to find phones that will support 4G. 
• Limit operator: Depending on the country and carrier ( Movistar, Vodafone, Orange and Yoigo in Spain ) will have a rate available will depend on the implementations and infrastructure each. We can have the icon H on our mobile ( 14.4Mbps ), that if our operator only provides 7Mbps never reach that amount.
• Monthly Limit: Remember that most of the operators, to reach an amount of data consumed in a month, we reduce the speed ( usually 64 ~ 128Kbps ). 
• Limit coverage: Finally, as seems obvious, depend on the coverage of where we are. Depend on operators, we have available some guidance maps, such as Vodafone, Orange and Yoigo. Movistar does not offer fails.
