Circuit That Doubles Wireless Data Capacity
Kumu Networks have successfully partnered with major wireless carriers in the U.S. to test a technology that doubles the capacity of any wireless data connection. Technology Review reported that Kumu’s founders developed Wireless Full Duplex which enables a radio’s receiver to filter out interference from outgoing signals. The device can then transmit and receive at the same time—a “full duplex” connection—doubling the effective capacity of a single radio channel or making it possible to use one where two were needed before.
One of the key wireless carriers in the U.S. (whose name Kumu did not disclose) and Deutsche Telekom, a German telecom giant, have now shown that doubling capacity is feasible in real cellular networks. Earlier in September, Deutsche Telekom installed a small LTE cell tower containing Kumu’s technology on a rooftop in Prague. The capacity-doubling technology worked in varying conditions, says Steven Hong, director of product and a cofounder of Kumu.
However, as the first test of such technology, there are still many things to iron out. The product still needs to resolve the interference experienced when the trial devices are close together. It also has not achieved optimum speed when adapting to environmental changes such as changes in location and cars passing by. Hong recognizes these but says Kumu is already working on them.
The company hopes to make its technology compact enough to fit inside mobile devices while expanding the capacity of wireless data networks.
Network extender that gives you five bars of signal
5BARz International (OTCQB: BARZ) has recently launched the 5BARz network extender, the revolutionary product that enables wider and stronger network coverage. The network extender is a lightweight compact device that provides strong network signal when used in small offices or at home. 5BARz incorporates a patented technology to create a highly engineered, plug-and-play unit that strengthens weak cellular signals to deliver high quality signals for voice, data and video reception on cell phones and other cellular-equipped devices.
“What it does is use a very advanced semiconductor and electronics technology to pull those base station signals out of the noise, re-amplifies them, and broadcast them wherever you have this,” said Dr. Gil Amelio, board chairman of 5BARz. “It’s a little box, you just plug it in the wall and forget it, and have five bars of coverage.”
This disruptive technology solution has never been done before. It is changing the way carriers design and build their network infrastructure. The 5BARz network extender is a lifestyle product that drastically improves mobile experience. The five bars of signal means no more dropped calls, delayed messages, sluggish downloads and data. With 80 percent more battery life, faster data and better voice quality on all your mobile devices, work and personal life connectivity is optimized.
Ultimate SIM that automatically switches between networks
Google’s Project Fi allows phones to automatically switch among multiple cellular networks and local area Wi-Fi networks, depending on which network offers the strongest signal at any given moment. This switching is hidden to the users, and the paid subscription allows Google to handle the technical and financial relationships with their partner networks. Project Fi is a program that constantly chooses the best signal among traditional carriers for a reasonably inexpensive service that is cancellable any time.
As a significant technical feat, it certainly challenges the business models that long dominated the wireless industry for decades. It provides an alternative to contracts with mobile carriers, especially if the service hasn’t been exceptional.
Google’s Project Fi allows users to switch from cellular network data to Wi-Fi while making a phone call—and still keep the phone call going. Unveiled this past April, Project Fi is available to a limited number of Nexus phones in the US with T-Mobile and Sprint as the network choices. It is due to arrive on a broader range of devices in the last quarter of 2015.
