Features of 3G technology

3G is third generation wireless technology It enhance the features that were available in the second generation and adds further advanced features. This technology is widely used in a mobile phone as well as data cards.

The ITU called international telecommunication union has proposed 3G telecommunications standard to provide cost-effective high quality, wireless multimedia applications, and enhanced wireless communications. The basic features are divided into two categories one is called data rates and the other is called security.

Features of 3G technology :
  • 3G technology is that support greater voice and data capacity and data transmission at low cost.
  • 3G technology has a large capacity and broadband capacity
  • 3G mobile can operate on 2G and 3G technologies.
  • 3G offer greater security features than 2G like network domain security, application security etc.
  • The 3G network has a much greater transmission capacity than 2G.
  • 3G technology provides major features like video calls, video conference, weather updates, accessing traffic etc.
  • 3G has improved security and performance.
  • 3G has a common spectrum worldwide. This result in seamless global connectivity.
  • 3G support a variety of terminals from like PDA to desktop.

2G technology features

2G technology is a second-generation wireless telephone technology, It is based on the technology known as the global system for mobile communication or in short we can say GSM. 2G technologies enabled the various mobile phone network to provide services such as text message, picture message, and also  MMS called multimedia messages. All text message is digitally encrypted. This digital encryption allows for the transfer of data in such a way that only the intended receiver such a way that only the intended receiver can receive and read it.

Features of 2G technology :
  • 2G is a digital version of 1G technology.
  • 2G technology became very popular because users were capable of connecting their mobile device to the internet and business networks.
  • 2G technology is utilized in digital signaling processing rather than the analog signaling used in 1G.
  • 2G technology support voice as well as data.
  • TDMA, as well as CDMA technology, must be used for multiple access
  • 2G technology must be used digital signal processing so it allowed a network to support data transfer as well as the voice traffic previously supported by analog signaling. 
  • 2G provided a speed of 135 kbps to customers at its peak.
  • 2G became very popular because the user was capable of connecting their mobile devices to the internet and business network.

1G technology features

1G technology is the first generation technology of wireless telephone technology. It was the analog telecommunications standard and it was introduced in the year of 1980, After that, it continued to replace by 2G technology.

Most popular 1G system during the year of the 1980s :
  • The first generation of cell phone technology
  • Advanced mobile phone system (AMPS)
  • Nordic mobile phone system (NMTS)
  • Total access communication system (TACS)
  • European total access communication system (ETACS)
  • Only referred to as 1G once 2G was introduced
The main difference between the 1G and 2G is that the radio signal used by 1G technology is analog while in 2G technology is digital.

Here this article gives some key features of 1G technology system :
  • Analog switching technology used
  • FM called frequency modulation is used
  • PSTN core network is used

  • Bandwidth around 10 MHz
  • FDMA techniques must be used for access
  • Mode of voice service only 
  • Only capable of simple phone call calls 

What is PNP transistor

PNP transistor structure :

PNP transistor consisting of a layer of N-doped semiconductor between two layers of p-doped material. In the collector output, a small current leaving the base is amplified. If its base is pulled low relative to the emitter, the PNP transistor is ON. The emitter-base region is biased forward in this type of transistor so that holes are injected into the base as a minority carrier. The base is very thin and most holes cross the collector's reverse biased base-collector junction. 

PNP potential barrier : 

In PNP transistor as more electrons and holes flow in the region of depletion, the number of positive and negative ions is reduced and the region of depletion becomes narrow. The energy loss in overcoming the barrier potential results in a voltage drop across the PN junction equal to the barrier potential in the range of 0.7 V for Si and 0.3 V for Ge. 


PNP transistor works : 

When you have a small current running from emitter to base of the transistor a PNP transistor will turn ON. When you say turn ON, means that the transistor will open up a channel between emitter and collector and this channel can carry a much larger current. As discussed, we need two depletion layers with specific barrier potential required to diffuse the depletion layer. According to the barrier potential most common type of transistor used is silicon because it is the most abundant element on the earth after oxygen.
