4G Mobile Price List 2021

4G is the fourth-generation cellular broadband technology for mobile devices, including smartphones, smartwatches, tablets, laptops, and various other connected gadgets. The 4G technology encompasses various sub-technologies, including LTE, LTE-Advanced, and Wi-Max, all of which have theoretical download speeds of more than 100Mbps and upload speeds of more than 50Mbps. However, practical 4G download and upload speeds vary depending on the network condition and congestion. The first commercial 4G network in the world was deployed in Sweden in 2009 and since then its rollout spread all over the world, including India where it was launched by Airtel in the April of 2012 (in Kolkata, based on the TD-LTE technology). Most 4G mobiles launched in India support both TDD-LTE and FDD-LTE technologies and are compatible with Band 1, Band 3, Band 5 and Band 40, since that's what most cellular networks in India use to deploy 4G networks. Airtel, Vodafone-Idea, and Reliance Jio have rolled out 4G LTE networks in India. BSNL will rollout its 4G LTE network in India starting the end of 2018. Wi-Max never became successful in spite of its rollout in Belarus, Nicaragua, Russia, South Korea, and the US. LTE is the most successful and widely available 4G technology around and world, and some telecom carriers upgraded their networks to LTE-A, but 5G technology is set to replace 4G starting 2020, with the launch of phones based on the Qualcomm Snapdragon 855 chipset and the Qualcomm X50 5G modem chip.
