= 1. PURPOSE =

To build and design a rural wireless mesh network to expand Broadband availability in the countryside setting of 2km radius.

= 2. BACKGROUND =

CEO Kari Zac – authorised the project, ICTNetworks asked that a rural wireless mesh network be built and designed to increase broadband availability in the countryside location. The main issues and outcomes is the implementation of routers if not already implemented, which will cost $599.90 to obtain 10 Wireless – G broadband routers. Correct choice of antenna, to allow increased range between the nodes. While maintaining a manageable sum for the company.

= 6. Recommendation =

The 12dBi 5.8GHz Omni WiFi Antenna is the recommended choice as onmi direction capabilities are perfect for this rural mesh network. Since Wireless – G Broadband routers v 1.1 are the perfect choice for rural mesh networks, this antenna is ideally suited for 802.11b/g while also fitting into it’s 2.4 GHz frequency range.

Since three electricians will be required to work 8 hours with, 5 days will be taken to complete all ten installations amounting to $2800 for 1 story buildings. For 2 story, it will take 10 days to complete 10 installations, amounting to $5600. The purchasing of the 10 antenna will cost $1099, while the cabling will cost $156. Fascia steel brackets will be used to mount the antenna upon the roofs totalling for 10 to $250. In total, it will cost for 5-day installation it will amount to $4080; while 10-day installation will cost $7105.
 * 7. **** COST SUMMARY **

= 8. Assumptions =


 * electricians have reasonable of knowledge to complete these installations
 * no interruptions i.e. strikes
 * 8 hour access to job site in order to at least complete 2 installations per day
 * No red tape i.e. once the project is approved no resistance
 * Staff get along
 * No compatibility issues with existing hardware and software
 * Project will be complimented within the price range of $4080
 * No unexpected system glitches
 * No acts of god have been considered
