Wireless Technology is the ability to communicate between devices without wires. Wireless Technology is a term that is used to describe communication, where electromagnetic waves are use for communication.
First forms of wireless communications
Drums used by tribes Smoke Signals Semaphore Flags
Used to convey messages via flags, paddles, or gloved hands
Light beams (short haul communication, Morse code)
Important people in the development of wireless technology
James Clerk Maxwell Helped discover the science of electromagnetism Heinrich Hertz Further clarified the studies of James Clerk Maxwell Guglielmo Marconi Helped develop the birth of wireless technology Nathan Stubblefield 1st wireless telephone inventor
1920s Police Departments Walkie-talkies WWII Germans used Enigma machines 1957 President Eisenhower Place a satellite into space to gather data
Wireless Network Infrastructure 802.11a
Approved standard operates in different rage than 802.11b
802.11b
Most Common system used
802.11g
Similar to 802.11b with speeds of 802.11a
Bluetooth
Uses the same unlicensed radio spectrum as 802.11
Infrared
Ranges from microwaves to lasers
Electromagne tic Waves Radio
Microwave s
Cordless Phones Remote Control Television
Presented by Ronda Wilson
1st use of radio - send and receive dot dash messages aka Morse Code Technology behind telegraphs Radio transmitters were called Spark gap machines Originally developed for communication between ship to ship and ship to shore
Wireless signals proved to be an effective way communicating Therefore the decision was made to advance the ability to communicate between two points. Ocean liners installed wireless equipment The USA Navy adopted the wireless systems in 1901 Up to that point, communication was done by…
German’s produce the most revenue in mobile technology with 115 million subscribers Main area of growth is in 3G and 4G sectors Market dominators are Telekom Deutschland and Vodafone Increase in resellers have raised level of competition and placed pressure on tariffs Resulted in lower ARPU’s

Wireless technology has affected us in a unique methodology rendering us emotionally numb, socially unskilled and psychologically indifferent without our awareness of this gradual change.

Waste from wireless devices Waste Electrical and Electronic Equipment (WEEE)
Europe implemented WEEE directive law on February 13, 2003. WEEEs purpose is where consumers return their used waste equipment free of charge; to increase recycling or reuse of products. One-third of WEEE is separately collected and managed appropriately; the remainder is either properly treated, improperly treated or even illegally exported, and/or disposed as part of residual waste (landfills or incinerators). European Commission has revised WEEE- Directive to increase amount of WEEE appropriately collected and reduce volume that goes to disposal. Between 2001 and 2009 there were large increases in shipment s in hazardous waste for both disposal and
hazardous waste, Germany is the biggest importer. Presented by Annabelle V allarta
Waste from wireless devices Cell Phones & other wireless devices
Contain hazardous materials such lead, mercury, arsenic, and copper. Encouraged to recycle to help with environment and to prevent from ending into landfills and polluting air, soil, and groundwater.
Batteries within our Cell Phones & other wireless devices
Before recycling can begin, the European Commission breaks down batteries into two categories; non rechargeable batteries and recharging batteries. 6 types of non rechargeable batteries (primary batteries): Zinc, Alkaline, Button alkaline, Silver zinc, Button zinc, Lithium ion 11types of rechargeable batteries (secondary batteries): Nickel- cadmium, NiMH (Nickel metal Hydride), Lithium, Lithium-Ion Polymer, Alkaline, chargeable Titanium, Lead SLI, Lead traction, Lead stationary, Nickel-iron, Nickel-zinc. Batteries are not collected separately enter the municipal waste stream and are landfilled or incinerated.

Health Concerns that come from wireless devices Cancers or other health conditions
Some causes of Cancer are; excessive sunlight exposure, genetic problems, and/or radiation Cell phones release radio waves also known as radiofrequency energy; a form of non-ionizing electromagnetic radiation Can be absorbed by tissues closest to where you hold your cell phone. Cell phone user exposure to possible hazards depends on the technology of the phone, the distance between the phone’s antenna and the user, the extent and type of use, and the user’s distance from cell phone towers. National Cancer Institute and American Cancer Society studies thus so far have not shown a consistent link between cell phone use and cancers of the brain, nerves or other tissues of the head or neck. Recommendation; be on the safe side and utilize hands-free devices.

Moral and Ethical implications that come with the use of wireless devices Morals are standards of behavior or beliefs about what is and is not tolerable for a society to do Ethics are moral principles that oversee one’s behavior. A decrease of face-to-face interaction; dialing one’s number, texting or e-mailing at will Is it better to respect the sensibilities of co-present others
when, for example, our phone rings in a restaurant In conjunction with our cellphones are the utilization and uprising of applications According to Summer McGee, Center for Practical Bioethics and University of Kansas Medical Center there will soon be an application to “test your saliva for sexually transmitted diseases (STDs). Privacy breaches, information getting into the wrong hands and announced publicly via email, texting, or social sites.

Countries rely on natural resources to boost economy Resources are used for trade, energy, manufacturing products and building roads & bridges Many countries build or improve their infrastructure to boost their economy Building or improving roads/bridges can create jobs, increase shipping as well as trading, so the GDP can increase Some countries may have more natural resources but they all have a frequency spectrum which can be used for the same thing
Presented by Matthew Tiemens
The frequency spectrum is a finite resource so it need to be divided Germany transitioned from analog to digital increases bandwidth Auctions provide revenue, as well as issue bandwidth so companies can improve infrastructure Germany requires mandates to auction bidders Outlying areas need to be built first
Germany has the 5th largest economy in the world but without many natural resources it needs to find alternative ways to boost the economy Germany has made a very business friendly environment for foreign companies With a strong wireless infrastructure Germany can: Lure business creating jobs Boost production Promote innovation Decrease government spending
Mobile apps becoming one of most lucrative businesses 18 billion Apple apps downloaded 10 billion Android apps downloaded App companies profit $1 billion a month worldwide Germany requires wireless providers to offer 4G service which can improve streaming Companies that offer streaming can expand Start-up companies have had good success with streaming, such as: Funny or Die and blip.tv
