Ongoing Projects
Seamless Data and Voice Connection Using Multiple Operators enabled SIM (MOES) Card

Call failure, call drop and low received signal strength are prominent features of various Nigerian GSM mobile service providers in Nigeria. Thus, the over 150 million GSM subscribers in Nigeria have adopted: the use of more than one cell phones; use of phones with more than one subscriber Identity Module (SIM) cards and hopping from one GSM service provider to another. Despite all the aforementioned strategies adopted by the subscribers, having seamless voice or data connection still continue to be a mirage despite the huge tariff from the service providers. This project thus is the design, development and fabrication of a novel seamless data and voice connection using multiple operator selective SIM card system. The system has the ability to perform vertical handoff from one network provider to another based on optimization of various metrics of quality of service (QoS ) thus providing seamless data and voice connection. Hence, the end to subscribers experiencing call drop, call failure and poor service connections. The seamless data and voice connection involved the development and fabrication of a miniaturized embedded system integrating the existing GSM SIM card with an artificial intelligent based Multi-GSM software application. On accessing the network, the embedded system in-built circuitry receive GSM signal strength and provide information about the QoS of each of the available network. Based on the received parameters, hybrid of artificial intelligence based Genetic Algorithm (GA) and Transportation Problem approach will be activated for parameters optimization and maximization of vertical handoff objective function in order to provide seamless data and voice connections to subscriber. The system provides the subscribers ability to enjoy good service from available operators without the added expenses of having more than one phone or a phone with multiple SIM slots. Furthermore, the device guarantees all time access to network with the best available signal strength and QoS even while on transit on Nigeria highways and roads.

Design And Production of Integrated Public Telephone Booth

A considerable number of precious lives and properties have been lost during emergency and disaster related situation due to the delay or inability to relay situation and incidence report to concerned agencies. Most often, when such incident happened, there may be no credit on mobile phones, lack of power on mobile phone due to the epileptic power supply in the country and nonavailability of GSM signal. Thus making it difficult to put a call through seeking for assistance or rescue operation. There-by limiting the source of calling for rescue operation to passersby which most times is not immediate and well prepared for. Solution proposed herein is the design and construction of integrated wireless public telephone booth for rural and emergency communication system. This proposed device will facilitate early dissemination of such emergency information to the appropriate authorities there by facilitating quick response and early arrival of rescue team. In design terms, a transmission line model will be used to design a rectangular microstrip antenna for use in the Public Telephone booth. Also, a modular approach will be used consisting of a microcontroller, special signaling input, display and antenna section. Each section will be developed and coupled together to produce a functional prototype. Real time experiments will be conducted to test the proposed public phone booths and results obtained will be analyzed to verify required functionality. Examination of the device's effect on improving the response time by appropriate agencies during cases of emergencies as well as it's used as source of internet data and income generation will be considered as proof of its overall contribution to the local development of the Nigerian telecommunication industry.

The proposed system is expected to: provide Public Phone booth with voice and data capabilities; increase efficiency of the microstrip patch antenna by decreasing the loss of the reflection; using air-gap technique as a substrate in microstrip patch antenna. It is expected that the designed telephone booth will be able to replace the archaic and out-of-use telephone booths in the country and at the same time compete favorably under all ramifications with foreign technology. The integration and ability of the phone booth to function as a wifi hotspot will make significant contribution in increasing internet penetration and at the same time serves during emergency conditions. The project will be completed within Twelve (12) months at the cost of Three Million and Thirty Six Thousand (=N=3,036,000:00) only.

Design And Development Hybridized Stove-Solar Charger for Mobile Phone

The non-availability of twenty-four hours supply of electricity has been shown to have negatively affect digital penetration and Information and Communication Technology (ICT) expansion within the country. This is because almost all foreign technology including mobile phone charger has been design under the notion of 34 hours availability of electricity. However, in Nigeria, the national grid has not been able to guaranteed regular supply of electricity required to sufficiently charge the battery that powers mobile phone. Attempts have been made in finding alternative methods of charging mobile phones due to this problem. Wind energy harvesting for charging mobile phone has remained unapplicable in Nigeria society due to numerous challenges. Similarly, Solar charging technique the preferred alternative suffers from inability to produce the required output power needed for charging mobile phone during night period. In addition, most of the existing one do lack Sun radiation tracking system hence operates below optimal level even during daytime. Despite Nigeria's high daily cooking rate, and culture of cooking during social gathering, majority of the masses still has problem charging their respective mobile phones. Hence, this work involve application of conservation of energy and Kirchoff's current theorem in harnessing the escaping heat from cooking stove and solar radiation from sunlight in the development of integrated stove-solar system for charging mobile phone battery. A two degree of freedom (DOF) artificial intelligent based solar tracking system (ISTS) will be used to monitor solar radiation and this will be hybridized with a thermal generator transducer that harness heat emanating from cooking activities. In deriving optimal usage for the device especially for use in rural environment where daily cooking activity may be low, additional functionality of charging multiple phones while maintaining maximum power output as well as energy conservation has also been considered in this proposal. Hence, novel Time Division Multiple Phone Charging System (TDMPCS) for charging multiple phones within shortest possible time has also proposed. Aside from providing alternate means of charging mobile phone, this project will also provide means of extending and storing the generated power over a long period of time using an intelligent output monitor and charging system. Furthermore, a blueprint for harnessing energy from cooking and relegating energy sources to the green alternative such as solar, wind and heat will also be established in this work. In addition, the developed product is intended to replace foreign mobile phone charger that was premised on availability of electricity over a 24-hour period. The project is expected to be completed within 18 months by a multi disciplinary and multi institutional research group at a cost of Two Million, six hundred and ninety thousand (=N= 2,690,000) only.

Dual Mode Mobile Phone Charger; Fan And AA Battery Approach

In Nigeria, most imported Mobile Phone Charger (MPC) required electricity supply for its operations. However, constant and regulated 220V 50Hz alternating current electricity supply required for daily living has remain a perennial problem, thus making some of these devices not to function optimally. The initial solution by teeming business communities in Nigeria is to import different brands of these MPC thus leading to proliferation of MPC in Nigeria society. Similarly, several efforts have been made by Government in reducing this menace of epileptic power supply. Also efforts have been made by individuals in solving this problem among which include the use of alternative power supply in form of imported 20V 50Hz alternating current generating set popularly known as “Generator”, solar charging system, battery power bank etc. Cost of petrol and associated risks with the use of Generator has made it out of reach of millions of impoverished Nigerians that earns less than 1$/day. Likewise, the setup cost and size of photovoltaic plate has made it to be out of focus to teeming Nigeria couple with the dependency on sunray availability. Gradual depletion and need to recharge the power bank upon depletion has also shown to be like the same initial problem of MPC. More importantly, the cells in all the imported power bank are non-replaceable thus leading to loss of income, environmental degradation and out of reach for the majority in Nigeria. Hence the need for an alternative solution. In this research proposal, a novel dual mode, energy efficient and highly durable MPC is presented for Nigerian Communication Commission funding. The proposed device uses the easily available low cost AA sized Battery popularly known as “Tiger Battery”, low cost nano- Fan and Energy efficient voltage booster system in the development of Mobile phone charger. The stored voltage in AA sized battery will be amplified in the voltage booster circuits to appropriate level for charging Mobile phone at a very fast rate, anytime and anywhere. At the same time, during transit or movement, the cooling fan attached to the system will also be used to generate voltages which will be used to recharge the battery and phone, thus making it the first universal dual mode battery charging system. This project will contribute immensely to Telecommuniation industry by making use of AA sized battery to charge mobile phones that already would have gone off. Thus instead of waiting for electricity or sunlight for charging phone, Nigerians can easily buy AA sized battery and charge the phone immediately. Furthermore, upon battery energy depletion, it can easily be recharged or dispose for other usage. There is also no time lag or delay in this type of charging as what you need to do is just buy the batteries, fix it to the charger and the phone start drawing voltages and power from the system for its operation and charging the phone’s battery. Similarly, the system can even be attached to Motorcycle aka Okada, Shaba, etc. to converts the locomotion into means of charging mobile phone. The system can also be attached to horse, goat etc so as to use them to charge the connected batteries and subsequently charge mobile phone thereby increasing users mobile phone battery life and availability. It is envisioned that this product will ultimately replace foreign mobile phone charger that was premised on availability of electricity over a 24-hour period. The project is expected to be completed within 18 months by a multi-disciplinary and multi-institutional research group at a Cost of Two Million and Thirty-Two Thousand, One Hundred (=N=2,032,100) Naira only.

Dual Mode Mobile Phone Charger; Fan And AA Battery Approach

The ability to communicate with each other and people around can be said to the most vital aspect of human life. The act of communication can be traced back to the days of the early civilization when smoke signals, flashing mirror and torch signaling were used to Pass information. However with advancement in technology as well as the introduction of the Global System for Communication (GSM) the act for communication amongst people have greatly improved and done in a lot more easier way all over the world. The ease and comfort of improved communication can be easily felt in most developing countries especially in Nigeria and neighboring countries with the extent of development experienced since the advent of the GSM in the Nigeria. However, the Recent analysis and complaints from both the National Regulator and the consumers shows that, the Quality of Service (QoS) provided has gradually and systematically deteriorated, thus causing a considerable measure of frustration to users. Most often, consumers are being charged exorbitantly for services not rendered. In some cases money is deducted without establishing successful call between subscribers. Cases abound where subscribers were unable to establish successful calls for several days. Thus, numerous users perceive QoS problems are prevalent in the Nigerian GSM networks today especially within densely populated areas such as the urban cities and highly compacted Nigerian Academic Institutions like the universities. In quest to solve this challenge, this research proposes the application of the already existing Wi Fi infrastructure within the Nigerian University Campuses in the development of robust and enhanced Intra and inter Wireless Communication system for use within the university campus through the development and fabrication of Wi-Fi enabled Communication server and accessories for intra and inter campus communication. The Architecture of the proposed system entails the development of an artificial intelligence based Wi-Fi communication network capable of providing seamless data and voice connections over the existing Wi-Fi infrastructure on various campuses. This is expected to provide a lasting solution to the problem of poor QoS often experienced by GSM subscribers in Nigeria and at the same time provide a new and alternative mode of intra and inter campuses communication. Upon the completion of the system it is expected to offer great extent of innovation through the inclusion of the framework for free Mobile communication services and Fabrication of Campus Mobile Communication System (CMCS) Server for intra and inter campuses communication. Furthermore, upon the expiration of the estimated duration of the 24 month, it is expected that an effective physical hardware realization of the server for the Campus Mobile Communication System as well as firmware for the client and user of the system would be developed at the cost of Five Million One Hundred and Thirty Five Thousand Fifty (N 5,135,050.00) Naira Only.

Development of a driveless mobile communication quality of service measuring device

Network performance and monitoring is an important requirement for Mobile Network Providers (MNP) and regulatory organization such as Nigerian Communications Commission (NCC). Hence, reason one of the main function of NNC is the development and monitoring of performance standards and indices relating to the quality of telephone and other communications services and facilities supplied to consumers in Nigeria. In addressing this problem, MNP have tried the introduction of different techniques and devices for monitoring network performance. Significant investment have been made in purchasing network monitoring tools and at the same time increase the number of conducted Drive test activities. The use of drive test is known to be time consuming, expensive and sometimes provide different results based on some inherent network and atmospheric related issues. Problems have even been identified with other prominent techniques Considering the impact of this sector to the economy, the concern for optimum service delivery experience by the end users is paramount. Thus, the motivation for development of an inexpensive; low cost; Artificial Intelligent and Digital Signal Processing (DSP) based QoS measuring device. The proposed device will augment if not totally replaced the existing network monitoring device presently deploy by various MNP. The device will have the ability to check against epileptic service delivery, identify instances where the network capability can be boosted, and to verify reports of poor QoS from the MNPs and end users. In addition, some essential Key Performance Indicator (KPI) used to estimate mobile network quality such as Call Set up Time (CST) can be easily obtained on realtime basis from the device. Intended contributions from this research work include but not limited to: Fabrication of a novel AI-based QoS equipment for analyzing CST and QoS estimation using standard network KPI data; Formulation of a Non-parametric noise reduction algorithm for QoS estimation; Development of a modified Adaptive Threshold Algorithm for telephony speech quality grading; Development of Mobile apps for QoS estimation; Development of Classification chart of Models used for reducing noise impairment in GSM dialing tone ; Design and Development of AI based GSM QoS prediction system and Development of a new CST estimation algorithm. The project is expected to be completed within 18 months by a multidisciplinary and multi-institutional research group at a cost of Two Million, Nine hundred and Six thousand ( =N=2,906,000) Naira only.

Fabrication of Intelligent Wireless Mobile Phone Battery Charger

All batteries, irrespective of their improved technologies will eventually run out of stored energy whether used or not. Thus, every battery must be recharged at some point in time. This emphasizes the importance of battery chargers in maintaining the functionality of a Mobile Phone (MP). Generally, MP batteries are recharged using either a portable battery charger (from 220V supply), USB power source (e.g from a Laptop), or from a vehicle’s cigarette lighter port. But in our highly mobile world, users further require that their MP batteries be charged on the move. This mobility requirement poses a challenge for the existing wire based charging systems because wires typically compel users to be stationary. In extreme cases, users who must charge their phones while walking will look awkward carrying their charging units around. Thus, the motivation for this project is to improve the capacity of MP users to freely move around while charging their phones. Specifically, the solution involves developing a Wireless Mobile Phone Charger (WMPC). Towards realizing the project, the proposed WMPC will have both a transmitter and receiver module. The transmitter module will comprise of an input source that will convert the mains AC voltage to DC (and it will also use a specific DC battery when user is away from mains supply), it will have an oscillator circuit that converts the DC voltage to high frequency signals, and a transmitter coil to send out the signal. This high frequency Electromagnetic (EM) waves will be sent to a receiver, which will respond to the high frequency signal, rectify the AC signal back to DC, and regulate to charge the MP battery. The completed project will be tested to ensure that minimum requirements regarding range, power levels, efficiency are met. Our proposed WMPC will be efficient and effective for charging phone batteries. Furthermore, this project will contribute positively to the telecommunication industry by creating a profitable business platform for Nigerians to sell and buy the finished product, and provide an alternative innovative solution to always keep our mobile phones well charged. The duration of the project will span eighteen (18) months and it will be completed at the cost of Three Million, One Hundred and Seven Five (=N=3,175,000) Naira Only.
