Mobile Broadband

Mobile broadband is wireless access used for devices such as hotspots, cell phones, and tablets. There are different generations of coverage, such as 3G (third generation) and 4G (fourth generation).

What are the 1G 2G 3G 4G 5G technology with pictures examples?

Cellular systems are described in multiple generations, with third- and fourth-generation (3G and 4G) systems just emerging:

  • 1G systems These are the analog systems such as AMPS that grew rapidly in the 1980s and are still available today. Many metropolitan areas have a mix of 1G and 2G systems, as well as emerging 3G systems. The systems use frequency division multiplexing to divide the bandwidth into specific frequencies that are assigned to individual calls.
  • 2G systems These second-generation systems are digital, and use either TDMA (Time Division Multiple Access) or CDMA (Code Division Multiple Access) access methods. The European GSM (Global System for Mobile communications) is a 2G digital system with its own TDMA access methods. The 2G digital services began appearing in the late 1980s, providing expanded capacity and unique services such as caller ID, call forwarding, and short messaging. A critical feature was seamless roaming, which lets subscribers move across provider boundaries.
  • 3G systems 3G has become an umbrella term to describe cellular data communications with a target data rate of 2 Mbits/sec. The ITU originally attempted to define 3G in its IMT-2000 (International Mobile Communications-2000) specification, which specified global wireless frequency ranges, data rates, and availability dates. However, a global standard was difficult to implement due to different frequency allocations around the world and conflicting input. So, three operating modes were specified. According to Nokia, a 3G device will be a personal, mobile, multimedia communications device that supports speech, color pictures, and video, and various kinds of information content. Nokia's Web site (http://www.Nokia.com) provides interesting information about 3G systems. There is some doubt that 3G systems will ever be able to deliver the bandwidth to support these features because bandwidth is shared. However, 3G systems will certainly support more phone calls per cell.
  • 4G Systems On the horizon are 4G systems that may become available even before 3G matures (3G is a confusing mix of standards). While 3G is important in boosting the number of wireless calls, 4G will offer true high-speed data services. 4G data rates will be in the 2-Mbit/sec to 156-Mbit/sec range, and possibly higher. 4G will also fully support IP. High data rates are due to advances in signal processors, new modulation techniques, and smart antennas that can focus signals directly at users. OFDM (orthogonal frequency division multiplexing) is one scheme that can provide very high wireless data rates. OFDM is described under its own heading.

What is 3g mb?

MB stands for mobile broadband. Mobile broadband is used in cell phones, and refers to the high-speed internet capacity. 3G is a type of mobile broadband that describes how fast the internet speed is.

What is the uses of 3g?

because it speeds up the internet on the phone so it is quicker to use.

Is video calling is possible on 2g network?

2g network does not have bandwidth connection higher for video transmission..

What is 2g in phones?

When they say its a 2g phone it means its a 2nd generation phone. Just like 1g 3g and 4g

What is 3g and 3d?

2d is a flat shape with only 2 dimentions (width & length)

3d is a shape with 3 dimensions (width, length and depth)

Can you sell your locked iPhone 3g?

YES, you can. There is at least one site online where you can sell your Used or Broken Iphones.

I suggest you get a quote so you would know the real value of your phone.

What is 3G in telecom?

International Mobile Telecommunications-2000 (IMT-2000), better known as 3G or 3rd Generation, is a family of standards for mobile telecommunications fulfilling specifications by the International Telecommunication Union,[1] which includes UMTS, and CDMA2000 as well as the non-mobile wireless standards DECT and WiMAX. While the GSM EDGE standard also fulfils the IMT-2000 specification, EDGE phones are typically not branded 3G. Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment. Compared to 2G and 2.5G services, 3G allows simultaneous use of speech and data services and higher data rates (at least 200 kbit/s peak bit rate to fulfill to IMT-2000 specification). Today's 3G systems can offer practice of up to 14.0 Mbit/s on the downlink and 5.8 Mbit/s on the uplink.

What is the average price for a used iphone 2g?

This price will completely vary based on who you are purchasing this from (second hand) online. The 2G original iPhone is not for sale in stores anymore, for it is six years obsolete. If you are not purchasing this phone as a collector's item, I would highly recommend purchaing a more usable iPhone like an iPhone 4 which you can get for free on a contract or $549 without.

What is the different of Apple iPhone 3g and china iPhone 3g?

Alrite. First of all,China does not have iPhone 3g..it is most likely a fake clone iPhone that is freaking slow..The only china city that sells the actual iPhone is Shanghai..it is exactly like the American iPhone 3g,but it is slower

What is the meaning of a 2G spectrum?

It is a term used in the telecommunication sector. It is a spectrum that supports 2G technology. High bandwidth is required for this purpose.

"2G" means second-generation wireless telephone technology. 2G cellular telecom networks were commercially launched on the GSM standard in Finland in 1991.

"G" has been superseded by newer technologies, such as 2.5G, 2.75G, 3G, and 4G; however, 2G networks are still used in many parts of the world.

There are three primary benefits of 2G networks over their predecessors: phone conversations were digitally encrypted; 2G systems were significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS text messages.

Was there an iPhone 2g?

The first iPhone (2007) is referred to as the iPhone 2G.

Although Apple just called it iPhone.

How is iPhone 3g?

The Iphone 3g is worth buying because it has alot of cool features like you can talk on the phone and download music off your phone form the itunes store on the phone and you don't have use the computer and you can buy all the apps you want for free and you don't hane to use a credit card.

Does iPhone 2g have app store?

The phone must be ugraded to the latest version of the iPhone OS, 2.2 or above. Then one will have access to the app store.

Are all cell phones 3G?

no, and there are different types of 3G, one would be UMTS for GSM phones. GSM phones are the ones that take SIM cards or smartchips (same thing) the other form of 3G is EVDO which CDMA/TDMA phones can use, these phones cant take SIM Cards most carriers have phones that have 3G capibillities, and usually offer 3G service only in metropolitan areas.

Do you have to pay for 4g if you have a 4g enabled phone?

If its a contract then yes you will have to pay for the use of 4G I think but I'm not entirely sure

How 2G network work?

---3G Network--- The third generation (3G) network provides very fast data access to the phones. You should be able to enjoy stream audio/video contents on a 3G mobile phone. But the availability of 3G phones and services is still limited. For PDAs, the story is much simpler. Unlike mobile phones, PDAs do not require subscription-based network services. They are standalone minicomputers, pretty much like PCs before the internet.

How do you get 3g internet on iPod Touch?

The iPod Touch can only access the internet over a Wi-Fi connection, however u can set up your mobile phone to transmit the incoming 3G signal into an outgoing Wi-Fi hotspot for iPod Touch. Essentially, u then have a Wi-Fi hotspot anywhere your phone and your iPod Touch both are.

i think in September or November last year but im not sure but im for sure that it came out in 2008

What happens if you jailbreak your iPod touch 2g?

What happens is you change all of apples things Like the app store..you get installer which you use to download app for free Cool backgrounds ..no more boring black background Loads of stuff like 3d app views 5 by 5 rows of apps But if it bricks (breaks) apple will not be responsible and u Will lose the warranty
