Solving the Bandwidth Crisis With a New Generation of Wireless Technology
Wireless wide-area cellular networks were a voice-only phenomenon for many years. What they did was straightforward: enable people to talk on a mobile phone. Wireless didn’t support data, so other technologies such as WiFi, WiMAX and other wireless standards emerged to provide that service.
As a consequence, today, we have a fragmented wireless landscape. During peak usage, traffic bottlenecks can form on some of these networks while others enjoy excess unused capacity. With the explosion in sales of data-hungry smartphones and tablets, wireless subscribers often find themselves getting far less bandwidth than what they paid for.
Of course, 4G technologies, such as LTE (Long Term Evolution), are emerging to ease the pain. Along with 2G and 3G, InterDigital has developed foundational 4G technology, and 4G promises to offer multiples in bandwidth improvement over 3G. However, even with 4G, problems remain to be solved.
According to Credit Suisse, for example, U.S. wireless networks are running at 80% capacity. Globally, the figure is 65%. Even in the parts of the country where 4G service has become available, we still see slowdowns and congestion during peak usage, because the networks can’t handle the traffic.
While mobile carriers are increasing their investment in mobile infrastructure, it is important to find companies that are carrying out important research into utilizing current and future bandwidth more efficiently.
What needs to be done?
Many smartphones and tablets contain multiple wireless interfaces, but lack the technology to use them intelligently. For example, a modern 4G smartphone usually has the ability to connect to 4G, 3G or WiFi networks. With additional interfaces, it could connect to other wireless networks, such as WiMAX.
What these phones do not do, however, is transition seamlessly between connections. They also do not connect to multiple networks at the same time to balance the data load across multiple networks, or perform quality of service duties (QoS) in order to automatically route traffic to the highest-quality connection.
Also, cellular networks distribute radio communication over a geographic service area. When your handset connects to the network, it connects to the nearest cell station serving your location. This service area is known as a cell.
Within a cell, however, performance can vary. If you are accessing the network near the edge of a cell, your network bandwidth can degrade considerably. This is true even with the latest 4G networks.
Pervasive wireless networks and higher bandwidth throughout the wireless cell are only two of the problems. Finding companies that are working to solve these problems could lead to profits for early investors. Solutions that are being created it right now…
