whitepaper For the system to compete, this paper shows that a system must and can efficiently use the limited spectrum allocated for broadband wireless services. It presents an analysis of system design parameters required to best use the limited spectrum...
[24 Feb 2004]
News Ofcom has released details of its plans to auction licences for the 'L-Band' of radio spectrum. Ofcom said there will be 16 lots of approximately 1.7MHz each for spectrum from 1,452MHz to 1,479.5MHz. The remaining spectrum will be auctioned as a...
[10 Dec 2007]
News Companies will soon be able to bid for licences allowing them to provide wireless broadband to consumers and businesses using the 3.4GHz spectrum. A number of companies are understood to be pushing the government to make the 2GHz spectrum available...
[10 Jan 2003]
News Telecoms regulator Ofcom is to auction four bands of high-frequency spectrum which could be used for wireless broadband services. Ofcom will conduct an online auction of individual lots of the spectrum on a "technology- and service-neutral basis".
[05 Dec 2007]
News Ofcom has published a consultation document on the spectrum requirements for the London 2012 Olympic Games. The consultation is seeking to identify what applications might need spectrum and whether they could more efficiently use what the regulator...

whitepaper Senator Dole, in particular, demanded that broadcasters, too, start paying for the spectrum they plan to use for next-generation digital TV. But their problem is that right now, almost anyone, it seems, loves to auction off spectrum: liberals...

whitepaper The Gaussian regime occurs when the relationship between device noise and oscillator spectrum is strongly nonlinear. We also analyze how the near-carrier spectrum of the phase-locked oscillator is affected by the nonlinearity in the dependence of...

whitepaper This paper will provide a brief introduction to the TeleManagement Forum's NGOSS (New Generation Operations Software and Systems) program and explain how Aprisma's SPECTRUM software maps to NGOSS. The TeleManagement Forum (TM Forum) is a non-profit...
[17 Jun 2005]
whitepaper The following paper is designed to explain how Aprisma's SPECTRUM software performs event correlation, impact analysis and root cause analysis for multiple vendors and technologies across network, system and application infrastructures.

whitepaper Today spread spectrum outside the military-only realm, ranges from digital cellular phones and wireless PCs to wireless LANs. This white paper presents a multi-code technology, an improvement over CDMA.
[24 Feb 2004]
whitepaper Spread spectrum technology was first introduced about 50 years ago by the military as a way of sending secure communications. Spread spectrum transmitters send their signals out over a multiple range of frequencies at very low power, in contrast to...

whitepaper SPECTRUM’s Response Time Management solution provides the flexibility to offer comprehensive SLAs based on end-user experience for performance in addition to the availability SLAs that are common today.
[24 Feb 2004]
whitepaper Spread spectrum radio is a lower cost, convenient way to connect LANs between buildings. Spread spectrum links come with a wide range of performance availability, from 1 Mbp to 10 Mbps, and operate in the license-free ISM (Industrial, Scientific...
[24 Feb 2004]
whitepaper Finally, we will discuss some of the reasons why a business would be interested in SLM and discuss Glaxo Wellcome’s approach to SLM using SPECTRUM. First we will define Service Level Management (SLM), and explain it using a common-sense analogy.
[24 Feb 2004]
whitepaper These two facts hold true for Cabletron’s own EMS, SPECTRUM: Planning a distributed deployment of Cabletron’s SPECTRUM requires the consideration of variables such as domain definition, modeling strategy and others.
[24 Feb 2004]
whitepaper Spectrum Analysis is a very broad topic. The second one addresses spectrum analysis of bandpass signals. However, we'd like to define what "real-time" means in connection with doing FFT spectrum analysis.
[24 Feb 2004]
News The European Commission (EC) has proposed the removal of restrictions on the radio spectrum previously used solely for GSM mobile phone networks. The proposals include the repeal of the 1987 GSM Directive which allocated the 900MHz-1800MHz spectrum...
[27 Jul 2007]
whitepaper Static Spectrum Management (fixed spectral masks) ensures that DSL lines in the same cable are spectrally compatible under worst-case crosstalk assumptions. Dynamic Spectrum Management (DSM) increases capacity utilization by adapting the transmit...
[11 Oct 2005]
whitepaper This paper discusses the impact of the new proposed European spectrum regulations on current and future UHF RFID applications. It comes to the conclusion that the proposed regulations will only support a very low RFID reader density and throughput...
[07 Aug 2007]
whitepaper This paper offers a novel anti-collision solution by using the spread spectrum algorithm to solve the anti-collision problem and eliminates the need for a two-way communication link. Radio Frequency IDentification (RFID) describes a system by which...
