Different Types of Mobile Network Technologies

Many people use mobile phones but do not know about the technology variances. In India, many mobile phones runs based on GSM and CDMA networks only. Now-a-days 4G is extremely growing in India which runs mainly based on LTE Network. So here there is a over view about the important and widely used mobile network technologies in India and across the World.

GSM

GSM – Global System for Mobile communication is the popular mobile network which is used in maximum parts of the World. It is developed by The European Telecommunications Standards Institute and is used by 2 Billion People (approx.) around the World. It is under 2G mobile network connectivity and mainly depends on 900 MHz and 1900 MHz network bands. It also supports 3G Technology across World. Some of the GSM network providers in India are Airtel, Idea, Vodafone, Tata Docomo and BSNL etc.

Some of the Features/Advantages of GSM Network are
  • Voice Calls
  • Call Forwarding
  • Call Barring
  • Call waiting
  • SMS – Short Message Service
  • Voice Conference

CDMA

CDMA – Code Division Multiple Access is a 3G wireless technology, which competes with GSM network and it is also used in different parts of world. Mostly CDMA Network is used in U.S, Canada, New Zealand, China, India and many. CDMA Network is the competitor for GSM Network in India and it depends on 450 MHz, 800 MHz and 1900 MHz network bands. Some of the CDMA network providers in India are Tata Docomo CDMA (Previously called as Tata Indicom), Reliance CDMA and BSNL etc.

Some of the key Features/Advantages of CDMA Network are

Along with GSM features, it provides
  • Good Signal quality
  • Voice Clarity
  • Minimizes signal break up
  • More reliable Network

LTE

LTE - Long Term Evolution is a 4G Technology developed for GSM Network. It is the first 4G Technology used in mobile phones across world and was proposed by NTT DoCoMo. It is a high speed data transferor for mobile phones with 299.6 Mbps (Megabits per Second) download speed and 75.4 Mbps up load speed. It depends on 700 MHz, 750 MHz, 800 MHz, 850 MHz, 1800 MHz, 1900 MHz, 2100 MHz, 2600 MHz frequency bands.

HSDPA/HSPA 

HSDPA - High Speed Downlink Packet Access is an advanced technology to 3G Technology i.e., 3.5 Technology. It supports a speed of 7.2 Mbps (Megabits per Second) but its actual speed is 3 Mbps only. It supports to load larger files, Mobile TV Streaming and Road Maps etc.

Another network based on this is HSUPA.

HSUPA – High Speed Uplink Packet Access is another technology besides of HSDPA. It is created by Nokia and supports a speed of 5.76 Mbps (Megabits per Second).

HSDPA and HSUPA together called as HSPA.

UMTS

UMTS – Universal Mobile Telecommunications System is also a 3G Technology i.e., 3rd Generation Technology which is commonly called as WCDMA (Wideband CDMA).  It provides faster data transfer rates at 42 Mbps (Megabits per second).

EV-DO

EV-DO – Evolution Data-Only. It mainly runs on CDMA Networks for 3G. It supports a speed of 2.4 Mbps (Megabits per Second) but its actual speed is 450 Kbps (Kilobits per Second).
