Welcome to this latest issue of the Basestation Newsletter, providing a last roundup of issues impacting the wireless basestation community before the summer recess! |
This year’s Basestation Conference (April 26th-29th) received widespread approval from the growing number of delegates. For those of you who were not able to attend, a recent article by Mike Roberts of 3G Mobile summarizes well the key issues addressed by the conference. Dates for the Basestation Conference 2006 are 9th – 11th May, Bath, UK. Looking back at this year’s conference the most significant feature, for me, is the rapidly growing complexity of the market in which we find ourselves. WiMAX is now taken very seriously by most basestation players – whilst acknowledging the position of this technology on the hype curve and how much there is still to do in standardisation and product development to realise the promises. The 3G in-building coverage issue is now combining with Fixed Mobile Convergence to create a major opportunities where WiFi can be both complement and competitor. And the 3G development accelerator is being squeezed to get HSDPA/HSUPA into the hands of operators screaming for them. Our challenge is to stay on top of this deluge of change and to pick out the key issues reshaping the industry through the conference and this newsletter. In this issue Matt Lewis of ARCchart provides an analyst’s perspective of this emerging complexity he christens the “Wireless Cocktail”. We received a wealth of high-quality material this month, including our first contribution from a major operator, Telecom Italia Mobile, covering some new approaches to ensuring high-quality in a deployed network. The Basestation Newsletter is increasingly recognized as providing a focused channel to the wireless basestation community around the globe. Enjoy! |

At the recent Workshop on Synchronization in Telecommunication Systems WSTS 05 – Boulder, Colorado – 10-12th May 2005, NGN and Mobile Networks were key topics. more>> |
| APOGEO: an innovative procedure developed by TIM Italia for improving the network quality (By Telecom Italia Mobile) |
|
|
With the development of radiomobile technologies from 2G (GSM) systems to 3G (UMTS) systems and VAS services based on localization, the need has also arisen to add an ever-increasing number of radio stations, with limited and controlled radioelectric coverage, to the network. more>> |

There is a huge pent up demand among 2 billion subscribers for high-speed data services. Operators are also scrambling to offer data services to improve ARPU (Average Revenue Per User) and hence profitability. more>> |
| Field Testing and Maintainence of 3G Basestations (By Stephen Hire and Ian Rose - Aeroflex Wireless) |
|
|
Traditionally, test equipment has been selected on the basis of test coverage versus price. However, today, operators additionally need to consider field technician productivity and skill level. more>> |

| Beyond Cellular – An Analyst Veiwpoint (By Matt Lewis – ArcChart) |
|

Over the coming years, step changes in the wireless industry will not be characterised by a serial overlay of evolved cellular technologies, such as the move from 2G to 2.5G and now 3G. Instead, it will be marked by the addition of evermore advanced wireless standards to a mixture of local, metro and wide area wireless technologies. more>> |
Increasing ROI with Improved GSM Coverage and Capacity |
|
|
Although the business market has an acute need for enhanced GSM coverage and capacity, it has not always been economic for operators to provide this with antenna-based solutions. An alternative – the IP-based picocell – is successfully challenging these economics. more>> |
| New DAC Generation significantly simplifies WCDMA TX Designs (By Heinz-Peter Beckemeyer - Texas Instruments) |
|
![]() |
Direct Up-Conversion has become the popular architecture for WCDMA transmit architectures. The latest DAC technology now allows simplified architectures because of an improved noise floor for avoiding noise filtering in or close to the TX band. The following article gives an in-depth overview of this major achievement with the lately introduced DAC5687.more>> |
| A cost-effective SDR platform for multi-antenna 802.16e infrastructure (By Jeremy Hendy – VP Marketing, Aspex Semiconductor) |
|
|
Many infrastructure vendors are planning the development of their next-generation platforms, to be launched in 2006/2007, with support for the emerging 802.16e standard. Using Linedancer, vendors can deploy a fully software-defined-radio solution, confident that it can be updated in the field to accommodate new standards and innovations. more>> |
| Converged Backhaul In Radio Basestations
Buzz Word Or Reality ? (By Martin Gassner, Agere Systems) |
|
|
New data services are a driver for the migration to IP based transport in the Radio Access Network (RAN). The subsequent requirements for data service provisioning include flexibility and backwards compatibility. These, combined with the expected cost savings of various kinds represent the main drivers for convergence in the backhaul. more>> |
| 802.16 Enables Versatile Broadband Wireless Systems (By Matthias Feulner, Texas Instruments) |
|
![]() |
As a complement to existing state of the art wireless technologies like WCDMA , 802.11 WLAN, UWB and others IEEE 802.16 is aimed at catering to a wide range of wireless link applications, ranging from backhaul for cellular base-stations or WiFi hot spots over fixed wireless access, to nomadicity, for example a laptop on the move, and eventually full mobility. more>> |
