RTT Technology Topics - 2004
We help companies and organisations maximise returns from existing technology and engineering investment.
RTT Technology Topics
Every month we produce a technology topic that reflects current
RTT research. These are sent to an elective list of engineering,
marketing and business team leaders.
There are over 120 Topics archived on this site starting from
August 1998.
The archive provides a free resource for researchers in the industry
wishing to use past experience to validate technology, engineering,
market and business decisions.
If you would like future Technology Topics sent to you
automatically each month then please join our
PUSH LIST
| 2004 | Title | Synopsis |
|---|---|---|
| December | OFDM performance and cost | Why OFDM is becoming increasingly prevalent as a way of improving PHY performance and some of the 'hidden' costs implicit in getting OFDM to work at a practical level. |
| November | 3G cost and quality | The cost/performance trade offs inherent in the Release 6 IP multimedia sub system (IPMMS) |
| October | Wideband wireless | The rebirth of short wave, medium and long wave digital radio wide band transmission |
| September | BLUWB? | How Bluetooth and UWB are evolving and how WiFi, Bluetooth and UWB might co-exist and complement each other in future applications including home networking and wideband wearable wireless |
| August | WiFi PHY | The WiFi physical layer (PHY) and related changes being made to the Medium Access Control (MAC) layer. |
| July | Five PHYS named FLO | How adding phys to a phone increases the phone's value both at point of sale and through life (operator revenue and margin). |
| June | Handset and network value | The interrelationship between handset and network value, the impact of Symbian based Nokia devices on network functionality. |
| May | Handset and network loading | The impact of handset hardware and handset software on the user experience and the related properties needed from the radio layer and the network. |
| April | Handset software testing | The software tasks and tests required to make multi-media handsets work with multi-service networks. |
| March | Handset hardware testing | The conformance and performance testing of 3G handset hardware |
| February | The impact of quality on session length | An important objective in 3G networks is to create the conditions whereby session lengths can and will increase over time. Quality and consistency are important pre-conditions that need to be met before this happens. Quality is a composite of power efficient source coding, channel coding, a flexible layer one, a deterministic network and good audio and video capabilities in the receiver. Consistency is dependent on trying to avoid too much band limiting of the channel and careful management of session maintenance protocols (the need to avoid dropped sessions). |
| January | Media Processor Design | Power optimized media processor design - the design issues implicit in specifying and implementing power efficient microprocessors for multi-media hand held devices. |
