Managing 4G QoS with limited Low-Band Spectrum: Insights and examples

[Ujjwal_Maghaiya]

Hello Experts.

Could you share some examples of low-band spectrum holdings for LTE in your country?

How are you maintaining 4G QoS with limited bandwidth in the low band?

Please share your experiences.

Japan: 3 MHz on 700 MHz band b28 lol

Can we understand why this bandwidth is used in Japan?

Is it for IoT, spectrum fragmentation issues, or for rural coverage?

[Hamza_Bouchebbah]

No, this is targeting indoor coverage and mostly basement and deep indoor coverage users in popular ward like in Tokyo, many basement are there.

Okay thanks

Typically, mature networks use low-band LTE spectrum for downlink supplementary CA only.

When low band is part of the mobility strategy, it can create significant issues with RAN KPIs, 4G QoS, and overall user experience, despite the minor dB gain in deep indoor coverage.

Band V, 5 MHz. Lowest priority among the carriers, outgoing load balance.
