Answer the following two questions:

A nationwide wireless carrier wants to deploy a network infrastructure to support broadband data service. The service area is a city of 100 square miles (such as Atlanta). They want to figure out the Total Cost of Ownership (TCO) for three different network configurations:

Config 1: 100% 4G (all area covered by only 4G Base Stations)

Config 2: For 50-50 4G and WLANs (50% of the area covered by BS and 50 % by APs)

Config 3: 100% WLANs (all area covered by only APs)

Requirement:

Based on the available spectrum and coverage of 1 square mile: It will need 10 Base station (BS) of 1000 Mbps OR 800 Access Point (AP) of 12.5 Mbps

Cost per Base Station

Initial fix Capital Expenses (CAPEX) $50,000 for hardware, $150,000 site, $5,000 for network connection

Monthly variable Operational Expenses (OPEX) $1000 site rental, $200 maintenance

Cost per Access Point

Initial fix Capital Expenses (CAPEX) $500 for hardware, $600 site, $300 for network connection

Monthly variable Operational Expenses (OPEX) $20 site rental, $10 maintenance

1. You will have to compute how many base stations and how many access points are needed in each configuration for the whole network of 100 square miles.
2. The Total Cost of Ownership (TCO) for N years is based on both fixed and variable cost incurred over N years. This assumes that the fixed costs are spread over N years and then you need to compute variable cost for N years. The sum of these two will be the TCO for N years.

Due: Submit the TCO for 3, 5 and 10 years. Show all your steps you used to get these numbers.

2: Strategy for managing future demands of data traffic for this wireless carrier as part of business model. This could include things like possibility of unlimited data plans; per GB pricing, innovative ways of charging, throttling of power users (slowing down their speed to discourage more uploads and downloads).

Answer rating: 100% (QA)

1 Configuration 1 100 4G all area covered by only 4G Base Stations From the information given above we deduce that 1 square mile will need 10 Base station BS of 1000 Mbps 100 square miles will therefo... View the full answer
