Trick That Doubles Wireless Data Capacity Stands Up in Cell Network Tests

Doubling Capacity of Wireless Data Connection


Start-up Kumu Networks, in 2012, rolled out of Stanford University to profit from a clever trick with the capabilities of doubling the capacity of any type of wireless data connection. Tests have been carried out recently by one of America’s biggest wireless carriers as well as by Deutsche Telekom, the German telecom colossal owning a major stake in U.S. carrier T-Mobile.

 It has been indicated that doubling is achievable in real cellular networks. The effects showed the products of Kumu Networks, for cellular operators could aid in expanding the capacity of mobile data networks. The company in the longer term anticipates in delivering further capacity boosts by developing its technology adequately compact to accommodate in mobile devices.

Kumu had invented in research which had disapproved the long held supposition that radios could not transmit and receive at the same time and that belief was established on the fact that if radios made attempts to do both at the same time, its outgoing signal tends to drown out incoming one. This is due to it being billions of times stronger and for this reason, the radios in our phone and computers tend to use separate channels to send as well as to received or switch in the midst of sending and receiving on a single channel.

Full Duplex Connection


The founders of Kumu had designed hardware and software which permits the receiver of a radio to filter out interference from outgoing signals. The device is said to then transmit and receive simultaneously what according to Kumu is known as `full duplex’ connection.

This tends to double the effective capacity of an individual radio channel. It could also make it possible to use one where two were needed initially. Kumu had worked with main wireless carriers this summer, on the first test of its technology in real cellular network situations.

An associate professor at Columbia University, Harish Krishnaswamy states that Kumu’s trialsrecommend the idea of full duplex wireless connection could bepractical though the company may have not made public, the detailed results. He mentioned that the work coming out of Kumu seems to be the first clue of realistic demonstration of the technology and there are still more challenges though they are seeing the possibility.

Wireless Carriers – Small Mobile Base Station


The first products of Kumu would be focused on wireless carriers which would be a version of the small mobile base station called small cells utilised to improve coverage in busy areas like stadium. Small cells tend to link back to carrier’s network utilising cable.

 Its version would be cable-free and would utilise the full duplex technology and at the same time serve the nearby devices making a high powered LTE link back to the central network.Creating small cells totally wireless could be helpful for carriers in deploying them in wider range of locations, improving on data coverage and capacity, according to Steven Hong, director of product and cofounder of Kumu.

He anticipates that next year, the carriers would test that product in the field attending live traffic. Kumu also seems to be working on a chip making it possible to reduce the package containing the company’s technology from the size of a hardback book to something similar to a credit card. Earlier in the year, Krishnaswamy’s group had demonstrated a full duplex chip smaller than a fingertip at Columbia and was confident that the technology would ultimately land in phones.
