B.       Phase – II (Feasibility Study)

C.        Phase – III (Survey Work)

 In this phase we work on Line of Sight (LoS), non line of sight (nLoS), ISP availability, selecting the ISP, uninterrupted power supply management, point to point or point to multipoint, Wireless Distribution System (WDS), bridging, cabling , maximum Data throughput possibility both for Voice and Data, better signal strength, deciding   the indoor and outdoor access points. Mobility and Location Management is an important requirement that users will place on wireless networks is mobility, freedom for the wireless user to maintain a reliable wireless connection while moving about an area that is relevant to the application. Some times even more complex situations might be encountered, with various metal surfaces, manufacturing machinery, and so on, all affecting signal propagation throughout the building. 

The goal of a WiFi site survey is to gather enough information and data to determine the number and placement of access points that will provide optimal wireless network      coverage. That usually means the support of a minimum data rate in a given area. A site survey will also detect the presence of radio interference coming from other sources that could degrade the performance of the wireless LAN.

 D. Phase – IV (Wireless Network Layout Design)

This phase is often considered under the heading network engineering, as they are issues concerning the design and operation of the network as a whole. Signal coverage prediction models, usually based on a combination of radio-wave propagation theory and experimental measurements, provide the designer with a means of estimating the optimum placement of access points, sites for covering the intended area of user terminals with acceptable signal quality. Even in a small office layout, planning for a WLAN installation must take account of the types and locations of office furniture and equipment, office partitions, walls, doorways, and so on, all of which can affect signal coverage. On-site wireless network layout design services can determine if wireless networking is a viable option for the location or can provide troubleshooting for problems with existing wireless networks. Common problems include lack of communication between mobile units and handhelds, or dead spots where the radios fail to work. WiFonic will send certified network engineers with all the test equipment necessary to evaluate or troubleshoot your situation.

E. Phase – V (Wireless Network Deployment Planning)

In this phase we define standard high level requirements for site installation then customized for site specific details.  To provide a fall-back to cover the possibility that unexpected events cause the installation of the new network to fail, or the new network proves to be unusable after deployment. Determine the potential areas of failure and define alternative approaches to recovery for each area.  Choose the best alternative for each potential failure area.  Ensure that the best alternative does not adversely impact some other aspect of deployment.  Look more fail over like equipment problems,  network problems, power supply problem, ISP backbone problem etc. Then we define procedures detailing the steps that must be followed to implement the contingency procedures to be used to restore the old network environment,  communications to affected staff during and after the implementation of the contingency, down time to be expected and the manual procedures to be used to continue service to customers during the down time, plans for redeploying resources made idle by the implementation of the contingency.  After that we define Installation Strategy of the proposed technology as per the case study.  For example, components may be received at a central site, staged, and then shipped to the final site. If equipment in use for development or training will be redeployed, define a strategy for the redeployment that minimizes disruption to development and production.

F. Phase – VI (Implementation & Installation)

Installation phase is the most physically demanding phase of the project. Using the site survey report, the installation should be a smooth process. The access points and antennas will be installed in the facility using the marked up drawing made after the site survey. Usually, the higher the access points and antennas are mounted, the better the signal will propagate. This will require the installer to have the ability to reach the support joists for the ceiling or roof. Some of the activities that will take place during the installation include but are not limited to:

►Mounting of access point

►Installation of enclosures on case-by-case basis

►Mounting of antenna

►Connection of antennas to access points

►Connection of backbone LAN to access points

►Connection of power to access points

►Installation and connection of remote power system

►Verification of coverage

►Proper firmware level

►Radio information (system ID, channel, bit rate)

►IP addresses (provided by customer)

►Verification of backbone connectivity: Ping access points Ping host

►Cabling and power runs should be done and tested prior to the installation of the access points.

G. Phase – VII (Testing )

After completing the installation, testing for proper operation and coverage may indicate the need to move access points and possibly use different settings.

H. Phase – VIII (Documentation)

Documentation on all the system hardware list, software, web admin userid and password, ip address, WAN IP etc. will be provided to the IT staff as an aid to be used when supporting the operational system.

I. Phase – IX (Demonstration)

As per the customer requirement and case study  a demonstration phase is conducted before the last phase, so that all the staff will get an idea about the wireless security, voice & data, mobility of location.

J. Phase – X (Training)

Explain both the documented and undocumented security vulnerabilities that are immediately created in every organisation when 802.11 wireless networks are introduced.  Describe in detail the types of attacks that occur.  Demonstrate practical 802.11 security vulnerabilities.  Detect authorised and unauthorised 802.11 wireless networks and access points.

As companies seek wireless solutions to gain a competitive edge, WiFi applications on the manufacturing shop-floor, in warehouses and points-of-sale will drive faster and more accurate transactions. Globally, organized retail sector is one of the largest consumers of enterprise wireless solutions. This sector is just opening up in India, as the global retail giants jostle for shelf-space to lure the massive middle class. These growth areas will drive up demand for Wi-Fi applications.

The growing Managed Services sector will extend into wireless enterprise as centralized servers will manage distant wired and wireless devices and applications for better control and improved operational efficiencies. Vehicular and goods control for transport and logistics organizations will continue to adopt wireless applications, many of which will be WiFi powered.

Wireless technology is a fact of life in today’s enterprise networks. The technology has been an area of rapid change over the past several years, which has led to confusion regarding best practices for deployment. As per the survey work made by Tonse Telecom the Laptops usage are growing very fast as compare with desktops. Again the next generation of mobile is like IPBX, MPBX, IPPhone, SIP, VoIP, iPhone  etc. which will be depending on WiFi.

 ►Wireless intrusion protection

 ►Authentication

 ►Encryption

 ►Access control

 ►Client security

Organizations implementing these best practices will be well protected against unauthorized and uncontrolled wireless as well as the malicious hacker bent on network intrusion. By implementing these best practices of the security policy, organizations will find that wireless networks provide stronger security protection than current wired networks, with the economic benefits brought about by mobility.
