The Security Implications of Virtual Local Area Network VLAN Niger Mills Calabar Nigeria
Virtual local area network (VLAN), is a logical grouping of network users and resources connected to administratively define the operation of activated ports on a switch. The creation of VLAN is saddled with the ability to develop smaller broadcast domain within a layer-2 switching router; by assigning different ports on the switch to different sub networks. The application was a re-design project carried out on the Niger-Mills’ network to improve the operational short falls identified by t...
Broadband Network Penetration and Growth Pattern in North Eastern Part of Nigeria
Information and Communications Technology, like many other classical innovations has been institutionalized and become myths binding on organizations. How this seditious tool can be used as a catalyst for developing countries, in the face of empirical anomalies has been a cause for concern. Why does increasing number of agencies go on-line and establish similar web presences with similar structures even when delivery to end user is poor or near impossible? What are the processes of adaption ...
Broadband – Infrastructural Deficit and ICT Growth Potentials in Cross River State, Nigeria
The study examined Broadband infrastructural deficit and the growth potentials of Information and Communications Technology in Cross River State of Nigeria, by using three–to-five scale closed-ended questionnaires. Cross River State has a population of about 3,104,446; yet by 2014, it was estimated that mobile Broadband connections in Cross River State was below 50,000 subscribers. Government statistics put Internet penetration in Nigeria at 28 per cent. Out of these, only less than 9 per c...
Issues of Variance of Extreme Values in a Heterogeneous Teletraffic Environment
The reliability of various teletraffic data-analytical devices in communication systems is relevant to all stakeholders. Among other key external variables, the performance of the network evaluated under a variety of traffic scenarios is the focus of the study: data / video traffic generated by subscribers, who ordinarily subscribed voice bandwidth services. This study, therefore views teletraffic data as complete random and in-deterministic variables, and examines its continuous dependence o...
Issues Associated with Decimeter Waves Propagation at 0.6, 1.0 and 2.0 Peak Fresnel Zone Levels
Radio waves propagation is dependent on many variables. Any of these variables employed must ensure that the antennae at both sides of the link can see each other. This is because the radio horizon extends beyond the optical horizon. Inspite of this porch, telecommunications’ long distance signal suffer degradation. The ratio of the transmitted power to the receiver power is empirically deteriorated. The level of the received signal fluctuation is usually a function of the configured charac...
Modeling a low potency ipnetwork in Nigeria.
— Investigations have shown that interior places of the nation lacked capacity for high speed Internet usage; except the cosmopolitan sections. This article, therefore, conceptualizes a robust Broadband roadmap that can effectively deliver IP-wholesale and IP-retail services, through traffic convergence. The interconnect platforms are designed to ensure automatic re-routing of broadband traffic during link or node failure. The IP-wholesale services can be delivered to all main cities in Nig...
DESIGN AND CONSTRUCTION OF A GSM-BASED MULTI-PURPOSE MEASURING DEVICE FOR UHF SIGNAL STRENGTH LEVELS.
It has become common for many business entrepreneurs to move with two or three mobile phones at any particular time in Nigeria. The reason is usually anchored on the epileptic reception of the telecommunications networks and their desire to keep in touch with their businesses. This burden can be made lighter if signal strength levels of Telecommunications’ operators can be periodically measured and predicted without resorting to the Network operator; like weather forecasting. The design and...
