    The results in the presentation should not be generalised; the

    results are just a snapshot (“moment-opname”).

    Hence, based on these measurements one can’t claim “operator X

    has the best LTE network”. 

    The results presented are a snapshot based on:

    Three networks in roll-out undergoing fast changes

    A very limited geographical area

    A short measurement duration (2 days)

    The main goal of this presentation is to demonstrate LTE

    measurement and analysis capabilities.

    The data results mainly demonstrate 2 networks in a

    different stage in their roll-out (in the area tested)

    KPN network in a more mature stage (in tested area) More & contiguous coverage (based on LTE800)

    Better throughput & web browsing experience

    VOD at early commercial stage (in tested area)

    Improvement possible in coverage & parameter tuning

    Some limitations observed (backhaul?)

    Bandwidth of 15MHz (LTE1800) has higher potential

    Call setup on LTE is excellent on both networks

    KPN has slower setup & return times

    Fall-back to 3G network

    Data sessions can be maintained during voice callFaster setup & return possible when introducing features

    VOD has fastest call setup time & return to LTE

    Fall-back to 2G

    Fast thanks to features on 2G

    At the expense of breaking data sessions during voice call

    Overall conclusion 

    37

    We have

    Demonstrated typical LTE benchmarking measurements

    Scratched the surface of technical analyses

    REMINDER: results are a snapshot and shouldn’t begeneralised

    LTE networks in Rotterdam and surroundings are in fast

    roll-out & change:

    Data performance is close to international benchmarks for KPN

    but not for VOD

    Voice performance is very good for both, and in particular good

    for VOD
