The unit of information technology in Bahar telecommunications company has implemented all of Information Technology infrastructures, according to the enterprise and business requirements of the company This unit has carried out this task by using updated and reliable solutions in order to perform commercial and administrative activities. The technical skills and knowledge provided by the Information Technology unit have created this capability to implement similar or more complex infrastructures. In the following paragraphs, we will give a brief description of the skillset of the Information Technology unit.
Generally, designing and installing computer networks is a specialized process that must be performed correctly. One of the concerns of company managers is installing networks within their own companies. A network is considered to be the main pillar of an organization and it is essential in the performance of an organization’s activities. One of the services that Bahar telecommunications company provides for its customers is installation of computer networks. Our experts are ready to give advice about solutions in this area to our customers.
Supporting computer networks is another service provided by Bahar telecommunications company. There are multiple services for supporting and and maintenance of networks that are designed based on the customers’ needs and requirements. Outsourcing of network services and Informatics help companies to receive specialized services with the least amount of price.
We can divide the steps for implementing a computer network in an organization into three main processes:
The design and mapping process is the most essential step in designing the computer networks of companies. This step is a process of needs assessment of an organization. In other words, it is the research process of designing computer networks for companies. In this step, before anything else, the company needs to assess its conditions in order to implement the infrastructure for the computer network. If these studies are not conducted and the design of the organizational grid is carried out based on assumptions, the cost of designing the computer network is not calculated based on the organizations real requirements. Therefore, in near or distant future, the cost of redesigning or adding active or passive equipment for the network has to be added. In order to prevent this, we have to consider the following factors:
The most important factor in the failure of network design is designing it after implementing the network. Just like studying the area for building structure, the network engineers need to study the area for implementing the best and the most cost-effective design for the computer network.
In the initial phases, passive and active experts of the network will study all the physical and logical requirements of the organization for implementing the network. In the second step, they will choose a plan with the most efficiency and cost effectiveness for implementing the network. The network designer can only perform these steps based on his knowledge and skills in this field.
The passive services of Bahar telecommunications will include all the hardware equipment of the network. The experts of the passive network will install equipment cables and ducting after specifying and confirming the final design of the computer network.The passive network services will include the following:
After installing the equipment for the passive network, setting up the software connection is needed in order to completely install the network. Providing software services for the computer network is called active services for the network. This software service ranges from configuring switches and routers to installing operating systems on servers and client servers.
Aside from installing networks within an organization, Bahar telecommunications company also offers optimization services for the already existing networks within organizations. The experts of Bahar telecommunications company also examine the problems within existing networks, changing the topology or developing networks and provide solutions for these problems. When there is a need to move a network from a physical place to another, it would be easily conducted by Bahar telecommunications expert. It is worth noting that networks installed by Bahar telecommunications company have the ability to develop and also locate to another place.
One of the recent advancements in computer networks is is the widespread use of WLAN networks by using WLAN network, the companies will benefit from many things. These benefits include decreasing the cost of implementing the network, lack of requirements for cabling, the possibility of connecting to the network in any place, adding to the number of new users to the network, etc. Using WLAN technology like using most of the computer network requires proper infrastructure and implementation. The first step to implement a wireless network is performing a survey site in order to determine if you can install needed equipment and determining the places you can use the access point of the network. A survey site is also used in conjunction with a software and determines the obstacles for implementing the wireless network infrastructure. Then, based on the employers’ requirements, we can provide and document a list of equipment with their prices. Providing comprehensive solutions from multiple equipment distributors (mostly Cisco) is done for installing wireless networks for small enterprises, implementing equipment and services and configuring access points. Installing wireless networks for indoor users has special requirements that has turned this area of skill set into a specialized field of work that is distinct from the wired networks field.
Comprehensive analysis of the network in multi-storey buildings and the network’s full coverage of the building for usage reliability are required for implementing a network.
The simplest type of implementing a wireless network with radio frequencies or fiber connections to communications centers or ISB IS installing one or multiple focused controllers and access points. Furthermore, if there is a GSM infrastructure in the website and there is no a proper network coverage within the site, we can also use methods such as Wi-Fi offloading.
After installing the equipment, we start by configuring devices, determining the free channels for each frequency and proper amount of power for access points to determine the least amount of interference.
Also, if it is required, we can use external antenna in devices that support them or if our employer demands, we can extend the reach of the network through Wi-Fi extender with the least amount of price. In the final stages of wireless network implementation, we will study RSSI and SNR in various applications of the site and we will give a report of the network coverage to our employers.
