Weekly Questions (Week 8)
Chapter Seven: Networks, Telecommunications and Mobile Technology
Wireless technology has provided businesses with many benefits. Wireless technology allows the user to access the internet through satellites, allowing personnel access to information such as reports, and files whenever they are needed. This has also enabled employees to work in any location, not just in the office. As such, this allows employees and owners to balance work and private life. Another benefit of wireless technology is the ability to manage and ‘keep track’ of inventory. Through the use of RFID technology, businesses are able to maintain ‘up-to-date’ information.

4. Describe RFID and how it can be used to help make a supply chain more effective.
Radio frequency identification (RFID) technologies use tags which transmits data/information to an electronic reader in the form of radio waves. There are 2 forms of RFID, passive and active. Passive RFID have no internal power source and can ‘power up’ to send data with a faint signal from the RFID reader, however active RFID have internal power and are able to send stronger signals and more accurate data.

5. Identify the advantages and disadvantage of deploying mobile technology
Advantages:
- The ease of sharing information
- Provides flexibility, user convenience
- Ease of implementation
- Able to manage inventory, data is continuously up-to-date
- Allow employees to communicate more efficiently

Disadvantages:
- Radio wave interference may occur if there are multiple antennas. This may disrupt signals and cause the loss of data
- Sending and receiving data is slower compared to fiber optics
