Operators should deploy carrier grade Wi-Fi with their 14M outdoor small cells

April 23, 2014

As worldwide Mobile Broadband Traffic heads toward 200 Exabytes per year, operators deploy 4G LTE, LTE-A, plead for spectrum, and try to manage usage through policy and pricing.  The physics of mobile broadband radio do not follow Moore’s Law of digital scaling, so leading-edge operators are ready to address the physical realities of small cells.  Nevertheless, the question remains; why not deploy carrier grade Wi-Fi with the small cells?

4G LTE investment is set to accelerate throughout Latin America in 2014

April 17, 2014

ABI Research expects growth of 10% in mobile telecoms capital expenditure (CapEx) in Latin America, rising to US$6.1 billion. Upgrades and expansion of 3G WCDMA and 4G LTE coverage will result in radio access network-related spending capturing 40% of CapEx. Investment in small cell base stations is garnering momentum with 40% year-on-year growth in 2014 to US$484 million.

Mobile Data Backhaul: The Need For E-Band

February 22, 2013

Now that the need for ultra high capacity radios has become an unofficial requirement with a potentially large market backing it, the call for more spectrum savvy radios is in order. Traditional wisdom would have us assume that the legacy pure-play millimeterwave equipment vendors have this market clenched; however, every time there is a technology shift, as is occurring with the E-Band market, it opens the field up to new market leaders and a new competitive landscape. Thus, we have seen traditional microwave vendors throw their hats into the millimeterwave ring with various levels of commitment from OEMing/private labeling traditional millimeterwave vendors’ radios to designing their own millimeterwave radios.

TU Dresden uses National Instruments Platform for 5G Research

December 13, 2012
Wireless consumer's insatiable demand for bandwidth has spurred unprecedented levels of investment from public and private sectors to explore new ways to increase network capacity. Service providers, now deploying fourth generation networks, are already beginning to look toward and plan for fifth generation networks (5G) to meet the escalating demand. Researchers at TU Dresden (TUD) have begun investigations into 5G technologies using a graphical system design approach and National Instruments' software defined radio platforms. Using the NI platform, TUD researchers significantly compressed the time to transition from concept to prototype.

Solutions for Enabling Fast, Accurate and Efficient Testing of Voice Quality in LTE User Equipment

September 18, 2012
This application note is designed to provide you with the latest insights on how to best address the long list of test requirements when testing the voice quality of LTE UE, with the right VoIP test building blocks. Successfully providing voice support on LTE will require UE developers to bring together a host of new features and capabilities. Many of these items have been around for a while but have not yet been applied to mobile networking. Others are completely new. Regardless, bringing them together will likely cause significant test pain, as they will need to be tested in conjunction with LTE and/or IMS to be fully exercised.

Small-Signal Intermodulation Distortion in OFDM Transmission Systems

August 13, 2012
A system that utilizes OFDM/OFDMA, such as the E-UTRA (LTE) downlink or the IEEE 802.11a/g and the IEEE 802.16 physical layers, transmits OFDM symbols, each comprising a number of modulated sub-carriers carrying data or pilot symbols, with inter-subcarrier spacing being equal to or an integer multiple of a fixed frequency. The channel bandwidth (B) is determined by the number of 'occupied' (modulated) subcarriers and the subcarrier spacing.

IMS Architecture: The LTE User Equipment Perspective

July 17, 2012
The IP Multimedia Subsystem (IMS) dates from 3GPP release 5 almost a decade ago, but is now becoming a reality with the rollout of IMS-based LTE networks. IMS enables convergence on multiple fronts, including access types (fixed, mobile), service types, application control functions and convergence between telephony and traditional data delivery. This paper presents a high-level technical view of the IMS architecture as seen by LTEcapable User Equipment (UE).

Voice and SMS in LTE

April 6, 2012
