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.

Mobile Calls Being Cut Off? Your Network May not be to Blame


Apple & Samsung Smartphones – Inspection of Handsets in Sending/Receiving Signals

Smartphones like Apple and Samsung have been facing official inspection on their technical expertise as part of an examination by Ofcom on how their handsets tend to manage calls. Ofcom is the communication regulator in the UK who regulates the TV and radio segments, fixed line telecoms, postal services and mobiles together with the airwaves through which wireless devices are said to operate.

Ofcom tends to operate under various Acts of Parliament which include the Communication Act of 2003 and functions within the powers and duties that have been set for it by the Parliament in legislation.

It has been stated in the Communication Acts that Ofcom’s chief duty is to promote the interests of citizens as well as consumers. Ofcom receives funds by way of fees from industry in regulating broadcasting and communication networks together with grant-in-aid from the Government.

The communication regulator has ordered a self-governing testing lab in order to calculate how the famous smartphone send and receive signals. It is also investigating if some models seem to be more likely than the others in suddenly cutting off conversations. The research is in progress with sharp political concern on mobile coverage as well as the quality of reception in urban as well as rural areas.

Handset Design Affecting Reception

Apple had earlier been forced to admit reception problems with its iPhone 4, because of its antenna design.But according to Steve Jobs, CEO of Apple who has received an email from a reader stating that his new iPhone 4 was facing reception issues while holding it in his hand was informed that those with reception issues need to hold their phone correctly.

Till now the stress has been put exclusively on network operators facing government pressure in improving the capacity and coverage.Westminster sources with information of the research effort of Ofcom indicated that it would shine the spotlight on how modern handset designs could affect reception, for example by utilising the metal cases which could be a hindrance to the signals.

According to Westminster, `some of the manufacturers would not like what is being published by Ofcom; however it is of great important that people have the information available.

Results of the Study Waited

Various sources of UK network operators have stated that the finding would be anticipated eagerly and their own testing has indicated significant differences in the quality of the receptions on popular handsets.

But due to their reliance on commercial relationship with the manufacturers they seem to be unable in sharing the details with consumers without the risk of accusations. One source from the industry has informed that the `handset design as well as the performance could often have a great impact on the quality of service people seem to receive than the network that they use.

Ofcom spokesman informed that the results of the study of the handset would be made available within a weeks’ time and the findings would be based on the recently published maps of network coverage. We need to wait and watch on the latest development with regards to reception issues.
