This document discusses various short, medium, and long-range wireless networking options. Short-range options include near field communication (NFC), Bluetooth, ultra wideband, infrared transmission, and Zigbee. Medium-range options are Wi-Fi and wireless access points. Wide area options consist of microwave transmission, 3G and 4G cellular networks, and WiMAX which can transmit data over distances of up to 30 miles.

3. Short-Range Wireless Options
 Near field communication (NFC)
• Short–Range wireless connectivity
technology designed for cell phones and
credit cards.

4. Short-Range Wireless Options
(Con)
 Bluetooth
• Bluetooth is a wireless communications
specification that describes how cell
phones, computers, personal digital
assistants, printers, and other electronic
devices can be interconnected over
distances of 10–30 feet at a rate of about 2
Mbps.

5. Short-Range Wireless Options
(Con)
 Ultra wideband UWB
• Ultra wideband (UWB) is a wireless
communications technology that transmits
large amounts of digital data over short
distances of up to 30 feet and very low
power. Ultra wideband has the potential to
replace Bluetooth’s 2 Mbps transmission
speed with 400 Mbps rates for wirelessly
connecting printers and other devices to
desktop computers or enabling completely
wireless home multimedia networks.

6. Short-Range Wireless Options
(Con)
 Infrared transmission
• Infrared transmission sends signals at a
frequency of 300 GHz and above. Infrared
transmission.
• requires line-of-sight transmission and short
distances—such as a few yards.

7. Short-Range Wireless Options
(Con)
 Zigbee
• Zigbee is a form of wireless communications
frequently used in security systems and
heating and cooling control systems.
Zigbee is a relatively low-cost technology
and requires little power, which allows
longer life with smaller batteries.

8. Medium-Range Wireless
Options
 Wi-Fi:
• is a popular technology that allows an
electronic device to exchange
data wirelessly, including high-speed
Internet connections. The Wi-Fi
Alliance defines Wi-Fi as any "wireless local
area network (WLAN) products based on
the IEEE 802.11

9. Medium-Range Wireless
Options (Con)
 Wireless Access Point:
• a wireless access point (WAP) is a device
that allows wireless devices to connect to a
wired network using Wi-Fi
• Have maximum range of about 300 feet
outdoors and 100 feet within a dry-walled
building

10. Wide Area Wireless Network
Types
 Microwave Transmission:
• High-frequency (300 MHz – 300 GHz) signal
sent through the air
• Line of Sight Path About 30 miles

11. Wide Area Wireless Network
Options
 3G Wireless communications:
• 3rd generation of mobile
telecommunications technology standard.
• Support Wireless voice and broadband
speed data communications in a mobile
environment.
• Recent 3G releases, often
denoted 3.5G and 3.75G

12. Wide Area Wireless Network
Options (Con)
 4G Wireless communications:
• Will provide increased data transmission rates in
the 20-40 Mbps range
 WorldwideInteroperability for Microwave
Access (WiMAX):
• Set of IEEE 802.16
• operates like Wi-Fi, only over greater
distances and at faster transmission speeds.
• WiMAX can support data communications
at a rate of 70 Mbps.
