Low-band 5G spectrum, which refers to radio frequencies below 1 GHz, enhances indoor connectivity due to its superior penetration through obstacles like walls and buildings[1][3]. This is especially beneficial in urban areas where most mobile data traffic is generated indoors[1].
Compared to higher frequency bands, low-band spectrum offers better indoor signal strength[1]. Mobile operators can ensure seamless connectivity for users inside buildings such as offices, shopping malls, and residential complexes by deploying low-band 5G networks[1].
Low-band spectrum is particularly suitable for providing coverage in built-up areas, providing deep indoor coverage[7]. Evidence also shows that low-band frequencies improve user experience, particularly indoors[7]. Consumers connected using the 700 MHz band in Australia and Japan, and the 600 MHz band in Canada, had a better quality indoor signal than those connecting in the mid-bands[7].
