Although the total costs of building the project is largely dependent on my home size, my approach is justifiable since I have tried to keep cost down. Spending more money in building a network does not mean that the network is going to be perfect, but one can spend little and still achieve top quality if the appropriate hardware is initiated. As you can see, cost have been minimized by choosing lesser hardware, minimizing the amount of cabling required in building the network, as well sourcing free open source software. Nonetheless, like most equipment, the price typically goes up with added features, such as external antenna connector, higher output power, a more sensitive radio with bells and whistles. Once the network is selected, I determined the kind of setting that was responsive in building the network. I further integrated a TP-Link wireless dispenser to ensure that I connected my two PC desktops. Additionally, individuals who had smart hardware devices would also enjoy the network. After surveying the site, I realized that the number of rooms in the house limited the wireless network connectivity. Yes, cabling is an effective strategy of building however its costs and redundancy metrics limits the genuine productivity of the network.
However, I realized that the more I tried to eliminate the path between my access points and my devices, the more complex the network became. Given my amount of money, I realized that I was not in a position to get rid of every obstacles, hence minimizing the possibility was limited. I therefore, choose to use TP-Link for its 802.11b technology. The technology sources 2.4 GHz radio emissions showing up as noise on the signal strength meter (Deng et la., 2014, p. 150). The technology minimizes transport by moving using up the access point, using a directional antenna. I further realized that 1EEE 802.11b specifications details 11 minimized possible overlapping frequencies on which communications took place. I, therefore, minimized costs by setting low range overlapping cells with a high omni-directional antenna.
Likewise, my approach was responsive given the nature of my house. As I enrolled out my wireless equipment, I found my self-being directed in a different way by the existing conditions inside my house. For example, air conditioning ducts, pipes, microwave ovens, power lines and other sources influenced my choice of hardware leaping into the foreground as I walked around (Sklavos amd Koufopavlou, 2012). By the time I decided to set up a couple of nodes, I realized that the network had constant sources of noise and that was reflected in the area I was attempting to cover. However, I decided to extend the range, as in several mile point-to-point links where I engaged a survey the outlying environment other than walking the entire route in the network.
As you can see from the network, I lacked a very important component, security. From my budget, I lacked a provision for a firewall. In my small home network, I plan to operate critical company documents thus security is very important given that I will be operating a wireless network as well. Peterson (2000, p. 74) believes that a firewall in a computer network performs a role, which is very similar to that of a firewall in a building. My network firewall has to protect against many different attacks. These attacks include viruses, worms, denial-of-service (DoS) attacks, hacking and break-ins attacks with names like SQL-Slammer, Code Red and NMDA, which can appear in the network. I will therefore, engage changes where I will optimize an inclusive of memory, storage, networking and redundancy solutions.
I will therefore use the additional $ 1.000 dollars to build a firewall around the network, add more server space for redundancy and enroll a CCTV surveillance to limit physical break-ins. The mini table below indicates how I plan to use the extra $ 1,000 dollars.

I realized that security was the single most problematic issue, thus while investing more on memory, storage, networking and redundancy solutions I invested more on computer hardware. Furthermore, I realized that it was important to grow my infrastructure, by adding two more laptops.
