Project summary

Currently there is a great need to develop a cellular connection system for computers that will enable interconnection of computers as well as their connection to the Internet. I.e. to develop the same type of cellular connection system for computers as it had already been developed for the voice telephony. The existing technologies of data transmission do not allow developing a high-quality cellular connection system for computers.

The existing wireless networks to transmit data between computers (Stations (STA)) and the base stations (Access Point (AP)) cannot carry out transfer data in case of collision (Matthew S. Gast “802.11 Wireless Networks”. 2005). (In an 802.11 network, the base stations are called access points (AP); the users (computers) are called stations (STA).

Collision occurs, when there is a superposition (collision) of two or more signals. Collision may often occur:

  • When the mobile STA attempts to contact with AP, particularly when the server coverage area is wide and Hidden Nodes exist;
  • When Stations (STA’s) are located in the coverage area where the coverage area of two or more Access Points (AP’s) are overlapped;
  • When STA’s signals located within one AP coverage area arrive at other STA’s located within the coverage area of other AP’s.

Collision leads to decrease of the data throughput rate and sometimes even to complete data transfer failure.

We have developed a new data transfer technology (US Patent Application Number 20040202200), which solves the problem of developing a high-quality computer cellular connection system. The technology enables developing wireless systems that can transfer data in full duplex mode from STA to AP and from AP to STA with high accuracy despite presence of collision as well as allowing easy switching of mobile STA from one AP to another AP. (The existing wireless systems transmit data between STA and AP in the half duplex mode).

The developed method enables:

  • to separate the useful signal from the interference with low BER;
  • to create communication systems that possess a high protection from interferences;
  • plural subscribers to simultaneously communicate in asynchronous and synchronous transfer mode in the same bandwidth with one another or with base stations in wireless or wired setups or in apparatus or circuitry of electronics devices;
  • to provide the high level of bandwidth usage efficiency, comparing with existing methods;
  • to mitigate the influence of multi - path fading;
  • to maintain the security of the transmitted useful signal, consequently maintaining the confidentiality of the transmitted information, amidst strong interferences that can concurrently be sent along with the useful signal during the transmission;
  • to determine the coordinates, trajectory and the velocity of the objects, or other transmitting subscribers where the transmitting device is placed.

The developed method provides significant leap forward in wireless or wired communications. Such uses include: mobile, network cards, PC to base to PC, LAN and WANs, Hotspots, PDA, RFID or other Wired and wireless communications. It provides substantial enhancement of speed, security of content, than existing models.

In this particular project we offer to develop wireless system on the base of our technology that can transfer data in full duplex mode from STA to AP and from AP to STA with high accuracy despite presence of collision.

Expected Results and Their Application.

The existing wireless systems to date transmit between the station (STA) and the access point (AP) are working in the half duplex mode. They cannot carry out data transfer in case of collision. Collision may occur often: when the mobile STA attempts to contact with the AP, particularly when the server coverage area is wide and Hidden Nodes exist; when Stations (STA’s) are located in the coverage area where the coverage area of two or more Access Points (AP’s) are overlapped; when STA’s signals located within one AP coverage area arrive at other STA’s located within the coverage area of other AP’s. Collision leads to decrease of the data throughput rate and sometimes even to complete data transfer failure.

The wireless systems developed by us can transfer data in full duplex mode from STA to AP and from AP to STA with high accuracy despite presence of collision and will exceed the existing analogs with their technical parameters and will be of great demand.

The system that is going to be developed by our team can be considered as a base for the creation of global cellule systems for computers.

The goal of this project is:

  • to carry out development and research of the wireless systems to date transmit between the station (STA) and the access point (AP), on the basis of the method of data transfer developed by us;
  • on the base of the researched carried out, to develop recommendations on development of wireless systems based on our technology;
  • to create a base for manufacture and sales of the developed wireless systems that will exceed the existing analogs with their technical parameters and will be of great demand.

Proposed Business Summary.

Phase One: Although prototypes have been built and tested in the Labs, the first phase of the business plan includes building actual systems that work on a commercial basis, but on a limited quantity. During this phase, the systems will be placed at test cities in actual use criteria.

Phase one will be the pilot projects and test ground where actual working solutions can be deployed quickly and on a low cost basis.

Phase Two: Based on the results of Phase one, and having the actual commercialized working units, the company will add Sales and Marketing personnel to:

  • Find large telecom or wireless companies including mobile phones, walkie-talkies etc and strike Licensing deals for the technology.
  • Find strategic partners or vertical markets and produce and market actual devices for sale. In the event of enabling a strategic partner or OEM to market then the company will seek revenue share from sales.
