There are already high levels of frustration among wireless consumers
about performance of their wireless voice service, such as dropped
calls and inconsistent coverage. With the advent of data applications,
consumer expectations will only increase. So it is imperative that
3G wireless networks are optimized to deliver a superior data experience
that meets the growing demands of wireless consumers.
With this growth in demand for multi-media data services and bandwidth-intensive
applications, such as streaming video, the requirement for higher
data transfer rates will increase. The wireless network will strain
to accommodate these higher data rates and high volumes of traffic
generated by data services, impacting the network performance. For
example, a substantial reduction in cell coverage will occur as
cells shrink to support higher data rates. In this case, at higher
data rates, consumers/data users will experience a significant degradation
of service—including decreased throughput and dropped calls.
The effect would be that the majority of users would actually be
at the cell edge. It is here that ICT can provide the greatest gains
and meet the performance expected by data consumers.
Consequently, ICT allows the wireless operator to free up more network
capacity, essentially lowering the cost to deliver data services.
Data consumers can:
- complete data transfers more quickly, effectively achieving
greater than 50% improvement in data throughput.
- transmit larger volumes of data with greater integrity.
- obtain higher data rates in poorer radio frequency (RF) conditions,
particularly at the edge of cell.
- experience fewer dropped calls and experience a higher quality
of service.
