Understanding 4G Technology and Its Relevance for Nepal
Key Takeaways
- 4G represents the fourth generation of mobile networks, offering theoretical speeds up to 100 Mbps
- Nepal's NTC has secured the license, with service planned for Kathmandu and major sub-metropolitan areas
- VoLTE enables voice calls over 4G, but fallback to 3G or 2G occurs without it
As technology progresses, our everyday needs evolve alongside it, and few changes impact us more directly than improvements to mobile connectivity. The internet has become a fundamental part of modern life, and telecom providers continually work to meet growing user demands. Not long ago, mobile phones were limited to voice calls and text messages, but today we routinely send audio, video, images, browse the web, and upload content. Recent discussions in Nepal have focused on the arrival of 4G, a new generation of wireless technology that promises faster, more reliable connections.
4G, short for fourth-generation, is the latest step in mobile network evolution, succeeding 3G. In theory, 4G can reach peak speeds of up to 100 megabits per second, though real-world performance typically falls below this figure, still offering more than double the speed of 3G. It relies on a technology called OFDM, or Orthogonal Frequency Division Multiplexing, which splits data into smaller pieces for simultaneous transmission using MIMO, or Multiple Input Multiple Output, techniques. For most users, this simply means a noticeably quicker mobile internet experience.
In Nepal, the Nepal Telecommunication Corporation has been granted approval to roll out 4G services, having met the necessary licensing requirements. Ncell has also submitted its application, indicating competition in the market. According to the Minister for Information and Communication, existing 3G coverage will be expanded across the country, while 4G services are set to launch first in Kathmandu Metropolitan City and several major sub-metropolitan areas.
One limitation of current 4G implementations is that they lack traditional circuit-switched telephony components found in 3G. However, users can still make voice calls through applications that support VoLTE, or Voice over LTE, such as Skype, WhatsApp, Viber, and Facebook. Without VoLTE enabled, voice calls automatically revert to the older 3G or 2G networks.
The benefits of 4G are clear. It enables smoother voice and video calls, faster downloading and uploading of large files, seamless live streaming without buffering delays, and overall supports broader digital growth across the nation. As Nepal prepares for this next step in mobile technology, users can anticipate a more responsive and capable internet experience.
