3. Wireless PANs (Bluetooth – IEEE 802.15)
 very low range.
 wireless connection to printers etc…
Wireless LANs (Wi-Fi – IEEE 802.11)
Infrastructure as well as ad-hoc
networks possible home/office networking.
Wireless MANs (WiMAX-802.16)
Similar to cellular networks
traditional base station infrastructure system.

 Some Wireless Standards
 Usage Areas
 Conclusion

6.  Wi-Max (Worldwide Interoperability for Microwave
Access) is a wireless broadband technology.
 Which supports point to multi-point (PMP)
broadband wireless access.
 Wi-Max is basically a new shorthand term for IEEE
Standard 802.16 .

8.  The IEEE wireless standard has a range of up to
50 kilometers.
 Can deliver broadband at around 75 megabits
per second.

9.  802.16.1 (10-66 GHz, line-of-sight, up to
134Mbit/s)
 802.16.2(minimizing interference between
coexisting WMANs)
 802.16a (2-11 Ghz, Mesh, non-line-of-sight)
 802.16b (5-6 Ghz)
 802.16c (detailed system profiles)
 P802.16e (Mobile Wireless MAN)

10.  The 802.16, Wi-Max standard was published in
March 2002 and provided updated information
on the Metropolitan Area Network (MAN)
technology.
 The extension given in the March publication,
extended the line-of-sight fixed wireless MAN
standard, focused solely on a spectrum from 10
GHz to 60+ GHz.

11.  This extension provides for non-line of sight
access in low frequency bands like 2 - 11 GHz.
 These bands are sometimes unlicensed.
 This also boosts the maximum distance from
31 to 50 miles and supports PMP (point to
multipoint) and mesh technologies

12.  Bluetooth
 DECT (Digital Enhanced
Cordless Telecommunications)
 DSRC (Dedicated Short
Range Communications)
 HIPERLAN
 HIPERMAN
 IEEE 802.11
 IrDA
 RFID (Radio Frequency
Identification)
 WiFi
 WiMAX
 xMax
 ZigBee

13.  Connection oriented
 Connection ID (CID), Service Flows
 Channel access: decided by BS
 UL-MAP
 Defines uplink channel access
 Defines uplink data burst profiles
 DL-MAP
 Defines downlink data burst profiles
 UL-MAP and DL-MAP are both transmitted
in the beginning of each downlink subframe.

14.  A Regular Wi-fi Uses Contention access
Which means competing for AP.
 Wi-max uses scheduling MAC
Much Better for QOS required services EX:
VOIP , IPTV.
 Mesh Networking
Subscriber station and Base station at same
time.
 OFDMA

15.  Originally Working 10 to 66 GHz FDD or TDD.
 Now supporting 2 to 11 GHz with 802.11a
OFDMA with TDMA access.

16.  Broadband Internet Access.
 VoIP , IPTV services.
 Cellular Phones.

17.  Framework for the evolution of wireless broadband.
 Everything will be coordinated with Wi-Max.
 Standard for Wi-MAX mobile solution not finalized
yet.
 Test network in Skelleftea shows promising results.
 According to analysts Wi-MAX will take significant
market shares.
