Conclusions from the tests

• The usage for MPE FEC increases the tolerable
  Doppler shift for mobile reception by about 40 ,
  and reduces the required C/N by about 6 dB.
• For very low Doppler shifts the gain in C/N is
  reduced. It remains to be investigated if this
  effect occurs in a similar way when a new profile
  for outdoor/ indoor reception at pedestrian speed
  is used. Such a profile is still under
  development. First result point to the conclusion
  that TU6 is less applicable in such circumstances.

High-Speed Downlink Packet Access or HSDPA

• HSDPA defines a new W-CDMA channel, the
  high-speed downlink shared channel (HS-DSCH) that
  operates in a different way from existing W-CDMA
  channels, but is only used for downlink
  communication to the mobile.
• sometimes referred to as a 3.5G (or "3½G")
  technology.
• designed to increase the available data rate by a
  factor of 5 or more.

43
Focus of HSDPA

• HSDPA is a 3GPP release 5 feature for UMTS
  FDD/TDD.
• Main focus Enhancements for downlink packet data
• Background Servicesemail delivery, file
  download, telematics
• Interactive Services web browsing, data base
  retrieval, server access
• Streaming Services audio/video streaming
• Mobility 0-30 km/h (pedestrian low speed
  vehicular)

Oh no. Another 3.5G technology called Wi-Bro

• CeBIT 2005 Just when you thought Wi-Max was the
  end
• By Tony Dennis at CeBIT Friday 11 March 2005,
  1213
• BUNNIES DAZZLED BY the headlights is the best
  description for the look on the faces of the
  massed hordes of CeBIT press gangsters when
  Samsung casually announced it was rolling out
  something called Wi-Bro in June 2006. Another
  3.5G technology had suddenly been sprung upon
  us.Yes, Wi-Bro (Wireless BROadband) will go head
  on against the likes of Wi-Max (and OFDM for that
  matter). It aims to offer susbscribers a true 50
  Mbit/s high speed wireless Internet connexion.

46
Wi-Bro

• Plus it will work even when you're travelling at
  speeds up to 60 Kph.
• And it works at 2.3 GHz - which is exactly where
  stuff like Bluetooth and Wi-Fi sit at the moment.
• In case you still weren't panicking enough,
  Samsung proudly announced it had already signed
  up three Korean operators to offer it.

Siemens

• The test transmission used a 100 MHz channel in
  the 5 GHz range,
• The transmission was encoded using a new
  Siemens-developed signal processing technique and
  transmitted using Orthogonal Frequency Division
  Multiplexing (OFDM), an increasingly popular
  system for high-bandwidth wireless transmissions.

64
Radio Frequency Identification

• Radio Frequency Identification (RFID) is an
  automatic identification method, relying on
  storing and remotely retrieving data using
  devices called RFID tags or transponders.
• An RFID tag is a small object that can be
  attached to or incorporated into a product,
  animal, or person.
• RFID tags contain silicon chips and antennas to
  enable them to receive and respond to
  radio-frequency queries from an RFID transceiver.
  
• Passive tags require no internal power source,
  whereas active tags require a power source.

65
RFID

• 3 types of chip
• Passive No internal power. Current induced in
  the antenna by the incoming radio frequency
  signal provides just enough power
• Semi-active small battery. Antenna used for
  backscattering signal
• Active tags (Beacons) - have internal power
  source life of gt10years and a range of gt50 metres

66

• Today the smallest chips are measured at 0.15 mm
  2 and 7.5 micrometres thick
• The AMEX Blue credit card now includes a
  high-frequency RFID tag

67
RFID Applications

• Retail Inventory Control - Product inventory,
  theft detection, point-of-sale verification.
• Manufacturing - RFID can track how far a product
  has progressed through the manufacturing cycle.
  RFID technology can tie an individual product to
  its current physical location and track when it
  was manufactured, whether it was received and
  where it is located.
• Logistics Supply Chain - RFID can have a
  significant impact on every aspect of supply
  chain management, including moving goods through
  loading docks, to managing terabytes of data as
  information about goods on hand is collected in
  real-time.
