Comment: Do we need mobile broadband or wireless broadband?

2011 is destined to be 3G hot year, iPhone4 as the trend of smart phones in China has risen to become a social phenomenon, which is Apple's unprecedented marketing success, but at the same time driving the unprecedented upsurge in market demand. I also have more and more colleagues and friends feel that it is important to surf the internet anytime, because they want to receive mail, to see stocks, to send micro-blog, to play video ... The eruption of demand of course also inspired the relevant telecommunications operators, system equipment vendors, terminal manufacturers incomparable enthusiasm, at this week's 3G Expo in Guangzhou, a large number of 3G industry-related equipment and applications are displayed, but also has a bright and beautiful blueprint is depicted ——— such as 4G, such as autonomous LTE, For example, HSPA can reach 168Mbps ...　　In these referrals, mobile broadband life is one of the most frequently mentioned words, and it seems that both operators and equipment makers believe that people will love the "mobile" broadband life more, but is that really the case? According to my experience, mobile broadband demand has been exaggerated suspicion. To be precise, the "mobile" broadband demand is not so strong that the real surge in demand is the "wireless" broadband and the further acceleration of broadband. Here is a question about the direction of industrial upgrading, with the current media widely concerned about China's autonomous LTE technology standards for example, its technical testing has shown a stronger than the existing 3G broadband expansion capability, is undoubtedly a development prospect, but in the implementation mode,　　The construction of LTE network means that Chinese operators have to rebuild a network, and then continuously optimize the quality, perfect coverage, according to China Mobile 2G network development experience, this process will take at least 35 years, but is it really worth it? In the case of domestic construction of 3G network, it will take hundreds of millions of yuan to rebuild a LTE network, and it cannot meet the needs of all the existing users at once, because the expansion of network capacity takes time, but its performance is not only at 100-200mbps level, It still has a lot of distance from the 1000Mbps of fixed broadband full fiber, and even with the existing 802.11n WiFi wireless extension technology, people can get 300Mbps rates on laptops, smartphones, Tablet PCs and other devices with wifi+ fixed broadband. In fact, the current so-called "mobile broadband" demand is not always in the "mobile" state of the generation, I believe that frequent business trips or mobile office friends have this feeling, even if we use 3G Internet card, most of the airport, hotels, Starbucks and other places to find a place to sit down to "fixed" the use,　　It's really rare to move on a bus, on a boat, or on a plane, which actually means that consumers need wireless broadband access anytime and anywhere, not necessarily broadband access in a high-speed mobile state. That soundsSome awkward, but to the industrial level is "small" and "big money" difference, take the individual consumer, the realization of wireless broadband only need for their own fixed broadband to buy a 200 or so WiFi router can be done, one-time investment long-term use, and a 3G Internet card is required monthly rent of 100 yuan has been handed down. The same is true for operators, the construction of wireless broadband networks only need to build on the existing fixed broadband network on the basis of large-scale WiFi hotspots, tens of millions of million-dollar level, but the construction of 3G or 4G network is different, often Chi or even trillion of investment, but also need to continue to improve and optimize costs　　The gap between the two is amazing.　　So in this sense, it is worth our discussion whether the 3G-4G network upgrade that keeps chasing the "mobile broadband" concept, especially in the case of a mature and low-cost wireless Broadband solution, is necessary for such a high investment duplication network.
