Huawei Redefines Mobile Access Networks with CloudAIR

 A Knowledge Network Article By Huawei Technologies
Monday 20 February 17

Mobile services have changed rapidly over the past decades, bringing significant benefits to our lives. Networks providing these services transmit data using specific radio access technologies (RATs) across specific spectrum blocks, with specific power levels, via specific channels (antenna). Such radio technologies and communication elements are tightly coupled, which inconveniences mobile operators and lowers network efficiency.    Present Challenges   Extremely high spectrum costs Spectrum is the most precious asset for mobile operators in the wireless communication era. To deploy new radio technologies such as 5G, mobile operators must remove certain spectrum blocks from LTE, UMTS, GSM and other existing technologies or buy entirely new spectrum.    The removal of spectrum blocks from existing technologies reduces capacity and degrades user experience.   Waiting for traffic to decrease naturally on existing technologies and releasing more spectrum to accommodate new technologies postpones network deployment, and deprives operators of the opportunity to cultivate high-end mobile users during the market initialization phase.   The cost to operators of buying more spectrum through spectrum auctions is extremely high. In Canada, Rogers paid 3.29 billion USD for 22 paired spectrum blocks, covering 33.36 million people in 2014. In the US, the AWS-3 spectrum auction cost operators 44.9 billion USD in 2015…
