3. Home Wireless Networks of Yesterday

• HomeRF was the first practical wireless
  home-networking technology.1
  
• It was launched in mid 2000, and provided a
  maximum transfer rate of 1.6 Mbps.1
  
• 802.11 was also available at this time, but less
  popular because it was more expensive.1
  
• 802.11 existed as two versions, and their
  transfer speeds ranged from 1 2 Mbps.1

4. Home Wireless Networks of Today

• As bandwith increases, the ability to share
  information with other home appliances becomes
  much easier.2
  
• Phillips and Sony have developed ways to stream
  high-definition video wirelessly, using 802.11a
  technology.3
  
• Gaming consoles, for example PS2, are capable of
  managing music, video distribution, and instant
  communication.3

5. Wireless Networks of Today Continued

• MSN TV 2 Internet Media Player allows you to
  use your home network to display photos that
  reside on your PC on your TV.4
  
• MSN TV also allows you to watch Windows
  Media-compatible video clips, movie trailers,
  sports highlights and other online media that is
  stored on your PC on your TV.4
• Security wise, 802.11i has improved security, and
  it focuses on authentication, encryption, and
  message integrity.3

6. Wireless Networks of Tomorrow

• The players involved with 802.11n are talking
  about quoted data rates of up to 250 Mbps and
  actual data rates of up to 175 Mbps.6
  
• Then there's a prototype connectivity technology,
  backed by Intel and others, that is a subset of
  ultra wideband wireless USB (WUSB). The expected
  data rate of wireless USB is 480 Mbps at a range
  of 2 meters and 110 Mbps at 10 meters. These very
  high data rates at close range would enable you
  to do things like point a camcorder at a PC and
  stream video wirelessly to the computer.6

7. Networks of Tomorrow Continued

• In home security, futurists see devices such as
  smart, Web-connected cameras and robots playing a
  role.6
  
• Sony, and others are at work developing
  next-generation IP cameras that can help
  homeowners keep an eye on their houses from
  wherever they are. You might find numerous
  wirelessly connected cameras inside and outside a
  home, each with its own IP address, motion
  sensor, remote tilt and swivel controls, and Web
  server features.6
• Robotic vacuums, digital washing machines that
  can control water flow for different kinds of
  loads, and refrigerators with built-in LCDs
  already exist, but haven't found their niche
  quite yet.6

8. The 802.11 Technology Series

• The 802.11 technology will be what wireless
  networks are based on. The 802.11 various flavors
  are listed below.3
  
• 802.11a has a 54Mbits/sec link speed, and can
  deliver a maximum usable throughput of about
  25Mbits/sec. It uses a 5GHz carrier frequency,
  which helps it steer clear of microwave ovens and
  cordless telephones.5
• 802.11b has a maximum link speed of 11Mbits/sec,
  and a peak usable throughput of around
  5Mbits/sec.5
  
• 802.11g offers a maximum link speed of
  54Mbits/sec, and maximum usable throughput of
  around 20Mbits/sec, four times better than
  802.11b, and not much slower than 802.11a.5

9. 802.11 Series Continued

• 802.11e adds Quality of Service (QoS)
  functionality that's nearly identical to that
  found in 802.1d standard used in the wired
  Ethernet world. It is especially key to allowing
  802.11 to stream video, audio and voice in real
  time.5
• 802.11i improves the notoriously poor security
  for wireless networks, with improvements in the
  area of authentication, encryption, and message
  integrity. 802.11i includes AES (Advanced
  Encryption Standard), which is a much stronger
  encryption than what's found on past-generation
  802.11 networks.5

10. Pros Cons of Wireless Networking

• Pros
• Frees you from network cables.
• Less analog, less time required to carry out
  specific tasks.

• Cons
• More expensive than wired, phone-line, or
  power-line alternatives.
  
• Difficulty with bandwith.
• Security
