- What is 4g technology interview questions
- A short name for Fourth Generation
- A stage of broadband mobile communications that supersede 3G
- 4G is expected to use radio spectrum in an efficient manner, and as a result, provides cable-modem transmission speeds to the end users.
- This feature enables high-quality streaming video
- Simultaneous connections to multiple high-speed networks, known as pervasive computing, are expected by 4G.
- Thus seamless handoffs are provided throughout a geographical area.
- Coverage enhancement technologies, like femtocell and picocell are expected to develop for addressing various needs of mobile users in homes, public buildings etc..

What is 4g technology interview questions
Explain i-appli protocol Interview question
i-appli
- i-appli is a Java environment based on CLDC.
- Handsets of NTT DoCoMos are utilizing i-appli
- It is similar to MIDP, however both APIs are incompatible.
Explain IDEN Protocol interview question
iDEN(Integrated Digital Enhanced Network)
- A wireless technology for Motorola
- It has the capabilities of digi-cellular phone, 2 way radio, alphanumeric pager and data modem / fax modem in a single network
- Operational bands are 800 MHz, 900 MHz and 1.5 GHz
- iDEN is based on TDMA(Time Division Multiple Access) and GSM architecture
- For voice compression it uses Motorola’s Vector Sum Excited Linear Predictors vocoder
- For delivering 64KBPS over a 25 KHz channel, it uses QAM modulation.
- iDEN is designed to serve the mobile user for accessing information quickly without carrying several devices.
Explain HLR Protocol interview question
HLR (Home Location Register)
- For GSM and CDMA wireless networks
- It’s responsibility is to authenticate and authorize subscribers and their services
Explain GPRS protocol Interview question
Wireless Interview questions
GPRS ( General Packet Radio Service)
GPRS ( General Packet Radio Service)
- Packet oriented mobile data service available to the users of 2G cellular systems.
- It is global system for communicating through mobile phones using GSM as well as in 3G systems.
- GPRS data transfer is charged per MB of traffic transferred, where as in circuit switching, data transfer is charged per minute of connection time
- GPRS is better packet switching service, as opposed to circuit switching.
- 2G cellular systems are combined with GPRS and known as 2.5G.
- Provides moderate speed data transfer by using unused TDMA channels, such as GSM.
3g and 2g technology difference
Wireless interview 2g and 3g
3g and 2g technology difference?
3g and 2g technology difference?
- Packet data speed is higher in 3G, and it is up to 384 KBPS
- Voice and sms speed is also 384 KBPS in 3G
- 2G utilizes different switching techniques for voice and data, where as 3G uses single switching, irrespective of data
- 3G has at least 2MB of data link of a mobile, where in 2G the data rate is in KBPS
- 3G has WiMAX facility for faster VOIP and internet
- 2G uses GSM TDMA technology with narrowband 200Khz.
- 3G uses CDMA technology with broadband 5Mhz, with same frequency carrier and time.

Advantages of 3G:
Advantages disadvantages of 3g technology?
Advantages of 3G:
- Overcrowding is relieved in existing systems with radio spectrum
- Bandwidth, security and reliability are more
- Provides interoperability among service providers
- Availability of fixed and variable rates
- Support to devices with backward compatibility with existing networks
- Always online devices – 3G uses IP connectivity which is packet based
- Rich multi media services are available
- The cost of cellular infrastructure , upgrading base stations is very high
- Needs different handsets.
- Roaming and data/voice work together has not yet been implemented
- Power consumption is high
- Requires closer base stations and are expensive
- Spectrum-license costs, network deployment costs and handset subsidies subscribers are tremendous.
What is 3g technology?
Wireless technology interview question
What is 3g technology?
Definition: 3G, known as 3rd Generation, is a standard for mobile / cellular phones. It provides the services that fulfill the International Telecommunication Union specifications.
The application services of 3G include wireless voice telephone, mobile internet access, video calls and mobile television – all in a mobile environment.
3G allows simultaneous use of speech and data services
3G provides peak data rates of at least 200 KBits according to the IMT-2000 specification.
Mobile broadband access of several MBits to laptop computer systems, smart phones is provided by latest 3.5G, 3.75G versions.

3G standards:
UMTS:
- Universal Mobile Telecommunications System – One of the 3G mobile telecommunications technologies, also being developed into a 4G technology.
- Most common form of UMTS uses W-CDMA as an underlying air interface.
- UMTS also covers Radio Access Network – UMTS Terrestrial Radio Access Network (UTRAN), and Mobile Application Part (MAP).
- Users are authenticated via USIM cards (Universal Subscriber Identity Module).
- Also known as IMT Multi-Carrier (IMT-MC), uses CDMA channel access for sending voice, data and signaling data between mobile phones and cell sites.
- The standards are CDMA2000 IX, CDMA2000 EV-DOR Rev.0, CDMA2000 EV-DO Rev.A and CDMA2000 EV-Rev.B. They are approved radio interfaces for the ITU’s IMT-2000.
