Introduction
This report proposes wireless enterprise network design for Jones hospital. A wireless LAN solution is proposed based on the business needs of the hospital. The premises comprise of one main building and six other buildings with a substantial number of employees. The management staff intends to deploy wireless network setup to adopt cost effective solution by replacing the existing leased line network. A wireless Local Area Network (LAN) will facilitate mobility and enhance productivity of the employees as they commute among the seven buildings of the hospital for daily operations.
The decision coming from the hospital management to replace the existing system shall provide an enhanced technology to the business operations of the hospital. The benefits of this technology over the existing one include increased mobility, installation simplicity and speed, wide reach of network, flexibility, reduced cost of ownership and increased scalability. The doctors and caregivers will be able to access real time information from any location of the hospital campus without getting disconnected from the network thus increasing their productivity. The buildings will get rid of cumbersome setup of cables through easy installation of the wireless system. The wireless system can be extended in future according to the requirement. Any changes to the network in future would be easily updated to sync with new configurations. Although initial investment will be high, but the overall expense will be lowered over time. Wireless network system shall render scalability to the hospital if needed at any point in time.
The report highlights the functional and non-functional requirements of the wireless LAN project for the hospital. It establishes the importance of network access control and how it can be incorporated within the proposed network design. The network design is demonstrated thoroughly elaborating on the equipment required to be installed in the main building as well as other buildings to enable connectivity among the equipment and authorized users within the hospital premises. The users include guests and employees. The hardware and software include routers, switches, firewall, wireless access points, virtual private network server and software. The components of the proposed network are critically analyzed and lastly, the constraints and limitations of the network are pointed out with certain recommendations for enhancement of the network in future.
Requirement Analysis
The proposal for the target hospital identified the following requirements. There is a main building with six other buildings in campus. The main building shall include the administrative block where the new patients are registered. The hospital management software shall be accessible to the employees. The software is installed at the server in the main building. The distance between access points of each building is within 200 meters. The computers in the other buildings may be increased according to future requirements. The non-functional requirements of the hospital network are
· Availability- Hospital patient records require 99.99% availability from anywhere and anytime.
· Reliability and maintainability
· Speed- Data should be accessible over the network quickly.
· Security- The health records are precious to successful operations of a hospital. The personal information of the employees as well as patients and their medical records should be safely and securely transmitted over the network.
The functional requirements of the hospital network are identified as
· Centralized Management
· Mobile device onboarding and policy management
· Secure guest access
The network requirements include
· Hardware in main building with quantity
· Hardware in each of the six other buildings
· Dynamic IP addressing for employees from central server
· Every computer should be able to access the hospital software from each building using fixed IP address.
· Network configurations
A secure Wi-Fi environment shall help improve efficiency, boost productivity and reduce errors through greater collaboration and real-time information at the point of work. A wireless network system shall provide mobile device access to health records while simultaneously providing disruption-free access to W-Fi enabled equipment. This shall include integrating patient monitors and telemetry devices and tracking shared medical equipment in the hospital buildings using RFID tags.
Network Access Control
The proposed network solution shall integrate centralized network access control into Wi-Fi solution within hospital premises to provide authentication of users for authorized access to network resources. Network Access Control (NAC) system plays a crucial role in providing visibility, access control and compliance capabilities thus strengthening the Hospital’s network security infrastructure. NAC shall render certain capabilities to the hospital network enlisted below
