It's not an exaggeration to say that smartphones
and other devices have replaced computers in many respects, and the arrival of
4G technology in China
will accelerate the replacement of PCs with smartphones.
In December 2013, the Chinese Ministry of Industry and Information Technology
(MIIT) formally issued TD-LTE licenses
to China Mobile, China Telecom and China Unicom. This marks
the advent of a new era
. In the future, there will be more and more devices
accessing 4G networks, such as cars, TVs, cameras, and even electric cookers
and refrigerators. The concept of the “Internet of Things
” removes all worries about whether the huge bandwidth
of the 4G era
will sit idle and unused.
Not long after the issue
of 4G licenses, the virtual operator license—a long-discussed topic in China—was
also finally settled. This means that users will have more diverse mobile
internet access options. Meanwhile, the three major Chinese operators will face
new operating challenges, including market factors and some technical problems.
So what does the future look like for wireless network
technology in China in the 4G era?
- The “small cells” concept in its various
forms has been discussed throughout the wireless industry. CommScope expects that
the components of future wireless networks will be smaller and inclusive of a
variety of solutions, including DAS (distributed antenna system) in order to better deploy revenue-generating services and devices.
- MIMO (multiple-input, multiple-output)
technology is a vital tool for improving the spectral efficiency of LTE and
more advanced cell sites. By using multiple routes between cell sites and
multiple antennas on users’ mobile phones, MIMO can improve capacity and
network performance. To implement MIMO, operators must improve their overall
noise performance, and we believe we can provide valuable solutions in that area.
- Remote radio unit (RRU) technology will
play an increasingly important role in the 4G era. It separates the radio head from
the baseband, making device deployment and maintenance easier. Implementing
RRUs at the tower top means installing fiber and power reliably and effectively
dealing with interface connections, which is what our Andrew SiteRise solutions deliver.
- The multi-beam base station antenna has effectively solved the multi-user, multi-channel
problem, and we expect these antennas can play a major role in supporting LTE
With its extensive global experience, CommScope
can confidently help Chinese consumers meet the opportunities and difficulties
posed by the 4G era. To get started, we have created a new Chinese version of our website to assist customers in finding the information they need to be
ready for 4G in China. I invite you to explore our website and join us in
envisioning the future of wireless.
