Data rates
  Unlike data rates on fixed lines, which are generally constant,
  data rates on radio access networks can vary with factors
  such as …
  • Interference (C/I)
  • Modulation type and coding scheme
  • Number of users in cell
  • Number of simultaneous calls in cell, and their type
  • Cell size
  • Distance of mobile from base station
  •…
  So beware of theoretical figures!

The performance of EDGE technology is
(watch out, implicit pun coming)

on the boundary between 2G and 3G
as defined by ITU’s IMT-2000 concept.
In some markets, this has led to confusion over whether operators with 2G-only
licences can run EDGE on their network.

                                                                                  11
Common frequency bands - GERAN
GSM owes its early success at least in part to
an agreement that all CEPT member countries         900 MHz
should allocate the same frequency bands to        1800 MHz
the GSM service.
GSM’s slow start in North America was in part       850 MHz
due to the unavailability of the European GSM      1900 MHz
frequencies in the USA and Canada.

Quad-band mobile terminals are commonly
available, and are usable in most territories of
the world.

Over the Releases, the GSM standards have          700 MHz
been extended to include other bands for use       450 MHz
                                                    410 MHz
in particular markets (particular countries,         810 MHz
                                                          …
specialist applications).

                                                       12
Common frequency bands - UTRAN
WRC allocated common frequencies for UTRA
on a world-wide basis.
                                                    2100 MHz



Further bands have subsequently been                 2600 MHz
allocated on a regional basis.                       1900 MHz
                                                1700/2100 MHz
(See table on next slide.)
                                                     1700 MHz
                                                     1800 MHz
Multi-RAT mobile terminals are commonly                900 MHz
                                                        850 MHz
available, typically supporting GERAN                        …

(GSM/GPRS/EDGE) and UTRAN.

As 3G takes over from 2G, so the 2G bands can        700 MHz
be used for 3G service.                              450 MHz
                                                      410 MHz

Transition time of less than 100 ms from a camped state, such as Release 6 Idle Mode, to an active state such as
Rel-6 CELL_DCH
Transition time of less than 50 ms between a dormant state such as Release 6 CELL_PCH and an active state such
as Rel-6 CELL_DCH
Control-plane capacity
At least 200 users per cell should be supported in the active state for spectrum allocations up to 5 MHz
User-plane latency
Less than 5 ms in unloaded condition (ie single user with single data stream) for small IP packet
User throughput
Downlink: average user throughput per MHz, 3 to 4 times Rel-6 HSDPA
Uplink: average user throughput per MHz, 2 to 3 times Rel-6 Enhanced uplink
Spectrum efficiency
Downlink: In a loaded network, target for spectrum efficiency (bits/sec/Hz/site), 3 to 4 times Rel-6 HSDPA )
Uplink: In a loaded network, target for spectrum efficiency (bits/sec/Hz/site), 2 to 3 times Rel-6 Enhanced Uplink




                                                                                                                     18

…
Mobility
E-UTRAN should be optimized for low mobile speed from 0 to 15 km/h
Higher mobile speed between 15 and 120 km/h should be supported with high performance
Mobility across the cellular network shall be maintained at speeds from 120 km/h to 350 km/h (or even up to 500 km/h
       depending on the frequency band)
Coverage
Throughput, spectrum efficiency and mobility targets above should be met for 5 km cells, and with a slight
       degradation for 30 km cells. Cells range up to 100 km should not be precluded.

Further Enhanced Multimedia Broadcast Multicast Service (MBMS)
While reducing terminal complexity: same modulation, coding, multiple access approaches and UE bandwidth than
       for unicast operation.
Provision of simultaneous dedicated voice and MBMS services to the user.
Available for paired and unpaired spectrum arrangements.
Spectrum flexibility
E-UTRA shall operate in spectrum allocations of different sizes, including 1.25 MHz, 1.6 MHz, 2.5 MHz, 5 MHz, 10
      MHz, 15 MHz and 20 MHz in both the uplink and downlink. Operation in paired and unpaired spectrum shall be
      supported
The system shall be able to support content delivery over an aggregation of resources including Radio Band
      Resources (as well as power, adaptive scheduling, etc) in the same and different bands, in both uplink and
      downlink and in both adjacent and non-adjacent channel arrangements. A “Radio Band Resource” is defined
      as all spectrum available to an operator


                                                                                                              19
                        E-UTRA


…
Co-existence and Inter-working with 3GPP Radio Access Technology (RAT)
Co-existence in the same geographical area and co-location with GERAN/UTRAN on adjacent channels.
E-UTRAN terminals supporting also UTRAN and/or GERAN operation should be able to support measurement of,
       and handover from and to, both 3GPP UTRAN and 3GPP GERAN.
The interruption time during a handover of real-time services between E-UTRAN and UTRAN (or GERAN) should be
       less than 300 msec.
Architecture and migration
Single E-UTRAN architecture
The E-UTRAN architecture shall be packet based, although provision should be made to support systems supporting
       real-time and conversational class traffic
E-UTRAN architecture shall minimize the presence of "single points of failure"
E-UTRAN architecture shall support an end-to-end QoS
Backhaul communication protocols should be optimised
Radio Resource Management requirements
Enhanced support for end to end QoS
Efficient support for transmission of higher layers
Support of load sharing and policy management across different Radio Access Technologies
Complexity
Minimize the number of options
No redundant mandatory features

                    Conclusion …

3GPP technologies show a continuing evolutionary path:
   • GSM
   • GPRS
   • EDGE
   • UMTS
   • HSPA
   • E-UMTS
   •…
which will keep them competitive not only with other mobile
technologies but with wireline broadband for years to come.
