Vision

Computers are integrated and offer
converged services
•
•

small, cheap, portable, replaceable
cloud-based processing and storage
Technology is in the background
•
•
•
aware of the environment and adapt
(“context awareness”)
recognize the location of the user and
react appropriately (“location awareness”)
Internet of “Things”

Enabled by Technology Advances
more computing power
smaller lower-power devices
new user interfaces for small dimensions
higher network data rates
multiple network interfaces
sophisticated multimedia processing
built-in sensor capability

Portable –v- Wireless -v- Mobile
Portable - a device that can be moved easily

•
Wireless - no wires needed for communication

•
•


E.g. Laptop computer
E.g. PCs deployed in a historic building
Our focus is radio frequency (RF), alternatives include
optical, infra-red
Mobile - the ability to continue to communicate
while moving
Demand for mobile communication creates need to
integrate wireless networks with the fixed networks
such as the Internet

Some Mobile Applications
Vehicles & Transportation

Road condition, guidance, accident avoidance
•
Travelling salesman

Mobile office; access to central databases
•
Fixed network replacement

Trade shows; historic buildings
•
Tourism & Entertainment


Effects of device portability

Power consumption
•


Loss of data more likely (theft, dropping)
Limited user interfaces
•

limited computing power, low quality
displays, less storage
compromise between size of fingers and
portability
Limited memory
•
limited value of mass memories with moving
parts

Wireless Networks -v- Fixed Networks






Higher loss-rates due to interference
Restrictive regulations of radio frequencies
Lower data rates
Higher delays, higher delay variation (jitter)
Security attacks are easier
Shared transmission medium

Early history of wireless communication

The Irish connection!
•
•
1896 Marconi (first
demonstration of wireless
telegraphy) – born in Italy,
mother and wife from
Ireland!
1901 (first transatlantic
wireless signal: Cornwall to
Canada, with monitoring
station at Crookhaven, West
Cork)
