Satellites

• Satellites can be divided into five principal
  types research, communications, weather,
  navigational, and reconnaissance.
• Communication satellites provide a worldwide
  linkup of radio, telephone and television.
• Weather Satellites provide continuous, up to
  date information about large-scale atmospheric
  conditions such as cloud cover and temperature
  profiles.
• Navigation satellites were developed primarily
  to satisfy the need for a navigation system that
  nuclear submarines could use to update their
  inertial navigation system.

Satellites (cont)

• Reconnaissance satellites have subsequently
  proved to have civilian benefits, such as
  commercially available satellite photographs
  showing surface features in great detail e.g.
  Kennan, AKA keyhole reconnaissance satellite

WIFI

• Wi-Fi short for "Wireless Fidelity", is a set of
  standards for wireless local area networks (WLAN)
  Wi-Fi was intended to be used for wireless
  devices and LANs, but is now often used for
  Internet access. It enables a person with a
  wireless-enabled computer or personal digital
  assistant (PDA) to connect to the Internet when
  in proximity of an access point called a hotspot.

WIFI

• How it has changed our lives?
• Unlike packet radio systems, Wi-Fi uses
  unlicensed radio spectrum and does not require
  regulatory approval for individual deployers.
• Allows LANs to be deployed without cabling,
  potentially reducing the costs of network
  deployment and expansion. Spaces where cables
  cannot be run, such as outdoor areas and
  historical buildings, can host wireless LANs.
• Wi-Fi products are widely available in the
  market. Different brands of access points and
  client network interfaces are interoperable at a
  basic level of service.

WIFI

• How it has changed our lives? (cont)
• Competition amongst vendors has lowered prices
  considerably since their inception.
• Many Wi-Fi networks support roaming, in which a
  mobile client station such as a laptop computer
  can move from one access point to another as the
  user moves around a building or area.
• Many access points and network interfaces support
  various degrees of encryption to protect traffic
  from interception.

11
Routers

• What are Routers?
• Transmits data
• packets
• Wired or Wireless
• Share internet
  connection

12
Routers

• Social Impact of Routers?
• Broadband connectivity for the home
• Effective workplace
• Marketplace

13
Routers

• Marketplace Force
• Large Audio/Video Files
• Time Savings
• Flash Websites

14
Bluetooth Technology

• What is Bluetooth?
• Short-range radio specification focused on
  communication between the Internet and Net
  devices, plus it defines communication protocols
  between devices and computers.
• How Bluetooth Works

15
Bluetooth Technology

• Bluetooth Characteristics
• It separates the frequency band into hops
• Up to eight devices can be networked in a
  piconet.
• Signals can be transmitted through walls and
  briefcases, thus eliminating the need for
  line-of-sight.
• Devices do not need to be pointed at each other,
  as signals are omni-directional.
• Both synchronous and asynchronous applications
  are supported, making it easy to implement on a
  variety of devices and for a variety of services,
  such as voice and Internet.
• Governments worldwide regulate it, so it is
  possible to utilize the same standard wherever
  one travels.
