Reliance Jio Expands Its 5G Network by Introducing the 26 GHz mmWave Band Across India

Reliance Jio has officially expanded its 5G services with the rollout of the 26 GHz band-better known as mmWave frequency-across 21 states and union territories in India.

This latest development marks a focused shift toward enterprise-grade 5G connectivity, as mmWave offers high-speed, low-latency performance, but with infrastructure demands that differ from traditional consumer bands.

Jio's mmWave Push: What It Means

The 26 GHz band isn't entirely new to the 5G ecosystem-it's part of the millimeter wave (mmWave) spectrum that's known for ultra-fast data transmission and reduced latency. However, the trade-off is its limited range, which requires a dense network of base stations to be effective. Because of these constraints, mmWave is primarily intended for enterprise-level applications, not everyday consumer use.

Reliance Jio has now introduced mmWave capabilities in states and territories such as Tamil Nadu, Maharashtra, Delhi, Gujarat, Rajasthan, Kerala, and West Bengal, among others. The move comes as part of Jio's efforts to meet minimum rollout obligations set by the Department of Telecommunications (DoT) and reflects its strategy to diversify 5G offerings.

Multi-Band Strategy: 700 MHz, 3300 MHz, and Now 26 GHz

Jio's 5G architecture is built on a three-band spectrum strategy:

• 700 MHz for wide coverage and indoor penetration

• 3300 MHz (3.3 GHz) for mainstream consumer use

• 26 GHz mmWave for high-capacity enterprise deployments

This layered approach allows Jio to cater to a range of connectivity needs-from rural coverage to industrial automation. The 3.3 GHz band continues to serve as the primary network for consumers, offering solid speed and reliability nationwide. But with the mmWave rollout, Jio is signaling a broader commitment to enterprise digitization.

Enterprise Access on Request

Interestingly, mmWave access isn't available to the general public by default. Instead, enterprises can request access to the 26 GHz band, depending on their use cases. This selective deployment approach supports industries that require high-throughput, low-latency connections-such as manufacturing, logistics, healthcare, and smart city infrastructure.

By focusing on targeted enterprise solutions, Jio is positioning itself not just as a consumer network provider, but also as an enabler of digital transformation across sectors.
