(麻豆淫院Org.com) -- A new report from the Global Information Industry Center at the University of California, San Diego examines the projected disconnect between U.S. wireless infrastructure capacity and consumer demand. According to 鈥淧oint of View: Wireless Point of Disconnect,鈥� wireless use is growing rapidly and if present trends continue, demand will often outstrip capacity, causing congestion.

鈥淲e鈥檙e currently experiencing a mass migration from wired networks to wireless networks, which under the best of circumstances have far less capacity,鈥� said Michael Kleeman, author of the report and senior fellow at UC San Diego. Wireless is much more convenient than wired connections for many purposes, but 鈥渨e must understand and accept the trade-offs we will face for the convenience of accessing limited wireless capacity. Alternatively, as citizens we need to dramatically lower our expectations for wireless services in the future.鈥�

Wireless data capacity is inherently different than fiber optic cables, which affects its performance. Among other differences, wireless is allocated a small portion of the available spectrum, and its signals are susceptible to interference from numerous sources, including weather and buildings. According to the report, even with advanced wireless technology, the capacity available to all network users in a given cell can be less than 1/000th the capacity of a fiber optic thread.  Wireless demand is also mobile and hard to predict, and when it exceeds capacity the result is dropped connections and slow downloads.

The "How Much Information? 2009 American Consumer Report" found that in 2008, Americans consumed 3.6 zettabytes of data including nearly five hours of TV viewing per average day. This is more than 3.5 pettabytes per day, which exceeds the wireless data network鈥檚 entire 2010 throughput. Increasing use of mobile video will be a major source of growing demand for wireless capacity.

The 2011 鈥淲ireless Point of Disconnect鈥� report highlights three strategies for addressing this disconnect, all of which have drawbacks and tradeoffs.  First, a key limiting factor is spectrum, and increasing and optimizing available spectrum are effective ways to increase network capacity. A combination of public and private strategies to optimize spectrum use should be employed and encouraged. However, many of the public solutions will take as much as a decade to implement. Second, carriers will increasingly need to manage traffic and develop triage and prioritization protocols, potentially including pricing-based mechanisms with real-time customer feedback to help manage network load.  Third, the industry can invest in more infrastructure, including cell towers and 鈥渂ackhaul鈥� cables. This will require community support.

鈥淭here is a lot of discussion about supply-demand issues for broadband Internet, but soon the same questions will be considerably more acute for wireless,鈥� said Roger Bohn, director of the Global Information Industry Center at UC San Diego. 鈥淭his report shows why future wireless systems will require adjustments, of one kind or another.鈥�

The report is in the center鈥檚 鈥淧oint of View鈥� series, which are occasional overviews by noted experts. They address topical issues in technology, business, and public policy.
