3 Introduction Home networking connects devices and appliances within the home It allows sharing of these resources and improves overall communication among family members Resources can include home electronic appliances, entertainment devices, PC hardware, and telecommunication devices Home networking is about the convergence of voice, data, and video, and their associated resources within the home Many people today are preparing their homes for tomorrow 3

4 Home Networking Trends Number of Networked Homes in the U.S. will reach 32.2 million by end of 2007 Growth drivers: broadband, multiple PCs, advancements in wireless networking performance Consumer adoption of home networks increased 60% in 2002 Wireless solutions were preferred means of connectivity among consumers establishing home network (Source: Yankee Group Research, April, 2003) 4

5 Methodology Design Goals Our group serves as the network design firm hired by a builder of a new community of homes Our firm will manage the design and implementation of the networking for 50 new homes in Loudoun County, Virginia Our firm plans to hire the necessary contractors to install cable, etc., and we will focus more on design and less on implementation 5

6 Methodology Community Layout 6

7 Methodology Assumptions New Subdivision with 50 single-family homes located in Loudoun, County, Virginia Each home will be occupied by mid-sized families (2-5) Incomes of 200K + are necessary to purchase in this community CAT 5e/6 cable will be installed for the LAN connection in each home The baseline cost of the homes will begin at $300,000 and the home networking budget will be additional to the baseline cost The telecom s CO is approximately 5 miles away from the community 7

8 Methodology Needs Analysis Broadband Internet access is a requirement for each home Each home has its own private LAN Share Internet access Share peripheral devices File sharing VPN connectivity to workplace and Video conferencing for telecommuting Community Intranet Access Host Virtual Community meetings via the Intranet Post relevant community news Remote Security Access Home Security Surveillance 8

9 Methodology Geographic Scope Access Layer Resides within each home either in a smart closet or a set top box All structured cable/optical fiber cable will terminate at this location Distribution Layer Each home will be connected to the street backbone, which runs parallel with each street Core Layer The community backbone will connect all of the street backbones together and run back to the Central Office (CO) 9

10 Proposed Distribution/Core Solution Fiber-To-The-Home FTTH is a network topology that deploys fiber-optic cable directly to the home It is capable of delivering converged data, voice and video services over a single fiber Two primary architectures to deploy fiber point-to-point point-to-multipoint (PON) 10

11 Proposed Distribution/Core Solution Fiber-To-The-Home FTTH uses two types of PONs: Asynchronous Transfer Mode (APON) Ethernet PON (EPON) EPON will be used because it offers higher bandwidth, lower costs and broader service capabilities than APON It is a popular technology for businesses and the few existing communities already using FTTH EPONs eliminate active electronic components (i.e. regenerators, amplifiers and lasers) from the outside plant The advantage of EPON is simplifying the network making it easier to deploy It offers a multilayered security such as VLANs, VPN, IPSec and tunneling. It can also deliver bandwidth in increments from 1Mbps- 1Gbps 11

12 Proposed Distribution/Core Solution Fiber-To-The-Home Advantages Virtually unlimited bandwidth capacity Costs of implementing are dropping Distance is not a major issue Less maintenance, less active devices Reliability and Security Highly scalable Solution to the last mile problem Limitations More difficult to deploy in existing neighborhoods Costs may seem high to subscribers that do not need a lot of bandwidth Needs battery backup for power loss Not widely available yet mostly used in remote areas 12

13 Proposed Distribution/Core Solution Fiber-To-The-Home 13

14 Alternative 1 xdsl DSL broadband technology provides a dedicated line between a user and a telephone company s CO A no new wires technology allows for highspeed Internet data transfer over existing copper wire There are two primary categories in the family of xdsl technologies ADSL (Asymmetric DSL) SDSL (Symmetric DSL) 14

15 Alternative 1 xdsl Advantages Affordable high-speed access Always on connection Delivers both voice and data over the same wire Limitations Distance limitations (must be within 18,000 ft of CO ) hurts performance High cost for rural areas Security issues 15

16 Alternative 1 xdsl 16

17 Alternative 2 Powerline Communication Powerline technology or Powerline Communications (PLC) is a rapidly evolving market It is a no new wires technology that uses existing wiring within the home and is typically easier to install than Ethernet The HomePlug Powerline Alliance is working on a next generation specification called HomePlug AV designed to handle100mbps by the year

18 Alternative 2 Powerline Communication Advantages Relatively inexpensive Uses existing electrical wiring Power lines can carry signals for long distances without having to regenerate the signal Claims to allow users to connect even if the power goes out Secure data encryption (56bit DES) Permanent online connection at low costs Devices can be located anywhere in the home (e.g. printers do not have to be connected to a PC etc.) QoS support if data packets drop below 1.5Mbits Limitations Can have transmission blocks and interference Hostile Network environment Tied to outlets Issues with bypassing transformers (not sure if this has been completely addressed) No absolute last mile solution to the neighborhood transformer can be cable, phone lines or wireless Bandwidth is shared among all users connected to the same local network station Still in the development stages Security is an issue if not set up correctly 18

20 Alternative 3 Satellite Broadband Disadvantages For areas that are not covered by terrestrial infrastructure or would be very expensive to build Quality limited by trees, rain, snow, location Latency which is unfortunately an unavoidable consequence thus leading to inferior TCP throughput Advantages Affordable technology of bandwidth-on-demand (BOD) An innovative residential always on two way satellite broadband connectivity Can provide redundancy and serve as a back up to primary fiber connections Can help avoid the congested terrestrial network and the landline local loop Can be deployed and up and running within days Can complement not compete with terrestrial 20

25 Alternative Bluetooth Access Layer Bluetooth Devices Computers, Mobile Phones, Camera Phones, PDAs, Home Audio Systems 25

26 Bluetooth vs Main differences: Usage, Power Consumption, Communications Range & Price : Created to connect to wireless LANs requires network Bluetooth: Personal Network Connectivity products require more power, more expensive Bluetooth has shorter communications range 26

27 802.11g Security Major concern for Wireless Products g family utilizes Wired Equivalent Privacy (WEP) Provides enough security to make it more difficult for hackers New Security Solution: Wi-Fi Protected Access or WPA 27
