Network frequency bands are often overlooked while purchasing any smartphone. Network bands are important related to coverage and data speed on your mobile. So, we will discuss about different network bands used in India on GSM, HSPA or UMTS and LTE.
Different Network Bands Used in India
With Reliance Jio, network bands came into hype. How Jio is delivering extremely high transfer speeds ? What is the technology they are using ? What is LTE ? What is Spectrum ? How Band 40 offers higher Speeds ? All these questions will be answered here.
What is a Network Band ?
Network band is a specific range of frequencies in a spectrum. With each band defined Upper and down limit. By default Spectrum is government property and it is leased by carriers for fixed amount of time. Government agencies allocates spectrum in auctions to various network carriers.
In India, Telecom Regularity Authority of India is responsible for spectrum allocations. Spectrum is allocated to network carriers Like Airtel, Vodafone, Jio, Idea, BSNL for interference free and unlimited usage. Before proceeding further, we must discuss some useful terms
Spectrum is collection of various types of electromagnetic radiations of different wavelengths. In simplified words, Spectrum is airwaves on which signals of network carrier travels.
Full form of LTE is Long term evolution and often referred as 4G. LTE is an standard for high speed wireless communication for mobile phones and data terminals.
Full form of GSM is Global System for Mobile communications. GSM is a standard for defining 2nd Generation of digital telephony which offers internet services on mobiles but relatively very low speeds.
Full form of HSPA is High Speed Packet Access. HSPA is combination of HSDPA (High speed downlink Packet Access) and HSUPA (High Speed Uplink Packet Access). It is an standard defined to improve performance of 3rd generation (3G) digital telephony with relatively much higher speeds than its predecessor 2G.
Downlink means transfer of signals from base station to mobiles.
Uplink means transfer of signals from mobiles to base station.
Network Bands Used in India
In India, GSM telephony works on two different frequency bands GSM900 and GSM1800 in MHz(mega hertz). Lower frequency network bands offers higher coverage while higher frequency network bands offers higher data speeds.
HSPA telephony in India works on two different network bands UMTS900 and UMTS 2100 in MHz. UMTS network bands are radio frequencies used by 3G. UMTS network bands in India are commonly deployed at 2100 MHz for better speeds.
LTE Technology in India make use of 3 network bands namely LTE850 (Band 5), LTE1800(Band 3), LTE2300 (Band 40). Band 3 provided great network coverage while Band 40 0ffers greater data speeds.
Among different network bands, Band 3 is already used by various network companies in India to provide 2G services. Band 3 runs on 1800 MHz spectrum and provides an superb ecosystem in world to deploy LTE services to users. In auction of 2015, almost every cellular company leased out Band 3 spectrum to provide their services. In India, Jio, Airtel, Vodafone, Idea, Reliance, Telenor, Videocon bags out 1800 MHz band to provide their 4G services. Only BSNL and Tata Docomo were not able to lease out this frequency band.
Band 5 is another out of another network bands that your smartphone should support. Band 5 runs on 850MHz which results into best network coverage. Reliance Jio has already launched its LTE services on Band 5 and network is available in almost every part of the country. Apart from Jio, BSNL, MTS and Docomo also hold this spectrum in their polythenes. Earlier smartphones does not included support for this band because it provides poor 4G speeds but best network reception on 4G network. But after Jio and their VoLTE smartphones, now smartphones includes support for Band 5 as well.
Another Popular Network Bands used includes Band 40 which run on radio frequency of 2300 MHz. It is specially used by 4G networks to provide their services with great data speeds. Currently, Airtel, Jio, Aircel and Tikona uses this spectrum for its service deployments. Band 40 is also supported on almost every 4G smartphones in India. Reliance Jio holds PAN India license for 2300 MHz spectrum and already launched it throughout the country.
Note : Reliance Jio uses all of three LTE network Bands namely Band 3, Band 5, Band 40. All three bands are required for VoLTE services and superb data speeds on Jio SIMS. Choosing Band 5 will provide better network reception while choosing Band 40 will provide greater data speeds on your mobile.
Better speed: 2300Mhz > 1800Mhz > 850Mhz
Better coverage: 850Mhz > 1800Mhz > 2300 Mhz
So, while purchasing any smartphone, you must consider these network bands support on your device. If have any queries and reviews on Network bands then feel free to ask in comments.
