— ReportsnReports.com has added a report “The 5G Wireless Ecosystem: 2017 – 2030 – Technologies, Applications, Verticals, Strategies & Forecasts” which says, despite the lack of sufficient LTE coverage in parts of the world, mobile operators and vendors have already embarked on R&D initiatives to develop 5G, the next evolution in mobile networks. 5G is expected to provide a single network environment to deliver not only existing mobile broadband and IoT services, but also new innovations such as self-driving cars, cloud robotics, 3D holographic telepresence and remote surgery with haptic feedback. At present, the 3GPP and other SDOs (Standards Development Organizations) are engaged in defining the first phase of 5G specifications. However, pre-standards 5G network rollouts are already underway, most notably in the United States and South Korea, as mobile operators rush to be the first to offer 5G services. Research estimates that by the end of 2017, pre-standards 5G network investments are expected to account for over $250 Million. Although 2020 has conventionally been regarded as the headline date for 5G commercialization, the very first standardized deployments of the technology are expected to be commercialized as early as 2019 with the 3GPP's initial 5G specifications set to be implementation-ready by March 2018. Between 2019 and 2025, we expect the 5G network infrastructure market to aggressively grow a CAGR of nearly 70%, eventually accounting for $28 Billion in annual spending by the end of 2025. These infrastructure investments will be complemented by annual shipments of up to 520 Million 5G-capable devices.

There is currently no known association between nonionizing radiation (NIR) and adverse effects on human health if the radiation level is below certain limits. Nevertheless, there is still concern about its potential effects on human health. This can influence the legislation of a country and the daily activities of a regulatory body. One way to overcome this issue is to improve the quality of information provided to the public. This article reviews how to estimate the total exposure ratio (TER) due to base station radiation and proposes a Java code and an Android app to show this information. © 2017 IEEE.

In Brazil, the 3625–4200 MHz frequency band (C-band) is widely used by TV receive-only (TVRO) application in the fixed satellite service (FSS). The 3400–3600 MHz adjacent band can be used by International Mobile Telecommunications (IMT) systems, but many low noise block downconverters (LNB) of TVRO sold in Brazil have not a C-band filter. Thus, it is likely that the low cost LNB used in TVRO receivers would be overloaded by the IMT-systems emissions within the LNB wideband receiver, even the IMT stations operating accordingly to international standards. This paper shows that both systems can coexist harmoniously depending on the characteristics of the IMT system and on the FSS receiver specifications. © 2017 Springer Science+Business Media, LLC

Digital Signal Processing: A Review Journal | Year: 2012
This paper proposes an implementation for identifying sparse impulse responses. The new scheme follows the approach in which the location of the channel response peak is estimated in the wavelet domain. A short time-domain adaptive filter is then located about the estimated peak to identify the sparse response. The primary purpose of this paper is to present an efficient design of such a system. The use of a new block wavelet transform results in up to 70% less computational complexity and improved peak detection, as compared to previous solutions. A new robust time-domain adaptive filtering location and update scheme is also proposed that significantly reduces the occurrence of jitter problems and leads to improved residual mean-square error performance. The behavior of the transform-domain adaptive filter is analyzed, the Wiener solution is determined, and an accurate analytical model is obtained for the mean-square deviation of the adaptive coefficients. Monte Carlo simulations show excellent echo cancellation performance for typical ITU-T echo channels. © 2012 Elsevier Inc. All rights reserved.

Wireless communications systems in a frequency reuse environment are subject to cochannel interference. In order to improve the system performance, diversity techniques are deployed. Among the practical diversity schemes used, Equal-Gain Combining (EGC) appears as a reasonably simple and effective one. Unfortunately, the exact analysis of the outage probability of EGC receivers is rather intricate for it involves the evaluation of multifold nested integrals. It becomes mathematically intractable with the increase of the number of diversity branches and/or interferers. For example, for N B diversity branches and N I arbitrary independent cochannel interferers, the exact formulation using the convolutional approach requires 2 + N B + (N B × N I ) nested integrals, which, very quickly, and for any practical system, turns out to be mathematically intractable. In this paper, we propose accurate approximate formulations for this problem, whose results are practically indistinguishable from the exact solution. In our model, the system is composed by N B branches and N I interferers so that the desired signals are coherently summed, whereas the interfering signals are incoherently summed at the EGC receiver. Three sets of fading scenarios, namely α-μ, κ-μ, and η-μ, are investigated. The proposed approach is indeed flexible and accommodates a variety of mixed fading scenarios for desired and interfering signals. © 2012 Springer Science+Business Media, LLC.

In a cognitive radio system where the primary user is a TDMA based system, spectrum sensing must be able to identify the occupation of both a frequency band and a time slot. Whereas this can be done by scanning each narrowband frequency channel in turns, we can also perform a wideband sampling of the transmitted signal, and identify simultaneously the occupied frequency bands and time slots by means of a time-frequency analysis. In this paper we propose the use of this approach, using a spectrogram, in order to sense the spectrum and determine the occupied channels of a TETRA system. © 2003-2012 IEEE.

Motorola could be preparing to launch two new versions of the Moto 360 smartwatch if regulatory documents filed to Brazilian telecoms agency Anatel are to be believed. Documentation for two Motorola products with the model numbers "360S" and "360L" have been submitted to the agency, which examines and approves all radio-equipped products before they can be sold in Brazil. Similar documentation was filed for the original Moto 360 before it launched in September last year, and last week, leaked video of what appears to be a second-generation Moto 360 found its way online. All this suggests that Motorola could be preparing to launch a successor to the Moto 360 and that the next-gen Android Wear device will be available in two sizes rather than one. This would make sense considering that Apple has gone down a similar path with the Apple Watch, and that, like many smartwatches, the original Moto 360 received criticism for being somewhat large and unwieldy. A screenshot of regulatory documentation filed to Anatel for the "360S." (Anatel) Unfortunately, the documentation submitted to Anatel doesn't offer much more in the way of details. Both the 360S and 360L are listed as having Bluetooth, Bluetooth LE, and Wi-Fi connectivity, with the S apparently featuring a battery capacity of 270mAh and the L offering 375mAh of power. These two battery listings would make sense if the S and L were different sizes, and the capacities also happen to fall neatly on either side of the original Moto 360's 320mAh battery. While we can't, of course, say for certain that we're seeing is a pair of as-yet-unreleased Motorola smartwatches here, we'll certainly be watching' for more news from the company in the coming weeks.
