Huawei’s CloudAIR Helps Bharti Airtel Deliver a Superior Economic 4G Experience

In a global first, Bharti Airtel has successfully deployed three radio technologies (GSM, UMTS, LTE) on the 900 MHz band within an 8.8 MHz spectral bandwidth by using Huawei’s innovative CloudAIR solution to deliver a superior 4G experience to its customers. CloudAIR offers spectrum cloudification to allow different radio access technologies to share spectrum resources dynamically instead of using traditional spectrum sharing solutions. This works via an on-demand spectrum allocation method replacing static allocation, which enables Bharti Airtel’s 900 MHz spectrum to serve GSM, UMTS, and LTE simultaneously.

Compared with traditional static allocation schemes, CloudAIR allocates fundamental and precious air interface resources which include spectrum, power and channel, in a dynamic scheme according to traffic demand or mobile user location. This helps mobile operators significantly improve their network spectral efficiency, capacity, and user experience.

 “In past years, we cooperated closely with global partners to innovate ways to maximize the value of their precious spectrum and offer better mobile broadband service. We are happy to see that our innovative CloudAIR solution delivers significant performance gain and business value for commercial networks.”

Dr Margaret Hu
President, Global Wireless Network Marketing,


 “CloudAIR gives us the ability to deploy LTE within the same 900 MHz frequency alongside GSM and UMTS. This improves our LTE coverage significantly, which means our customers enjoy superior data experience and HD voice quality even in indoor locations.”
