Recorded: 25th April The recording of the Beamforming and Massive MIMO - Enabling 5G webinar  is now available on Wray Castle Connect (Free Membership Required), you can view the recording here. 5G enables access to higher frequency spectrum than previous generations. In order to efficiently use that high frequency spectrum [and put very simply], antenna size needs to be smaller, and we need to use more of them. This in turn means that massive antenna arrays are a key component of 5G deployment - where lots of antennas are used in a very organised way to focus energy and drive...

Recorded: 23rd March 2023 Webinar recording of Radio Propagation Mechanisms Explained is now available on Wray Castle Connect (Free Membership Required), you can view the recording here. The aim of this Webinar is to explain the range of factors that impact the way radio waves propagate and therefore impact radio connectivity and coverage in fixed and mobile radio systems. The session commences with a look at how variations in atmospheric conditions will affect the trajectory of radio signals – the process of refraction.  The natural phenomena of diffraction, reflection, and absorption will then be described, finishing with an explanation of fast and...

3GPP Non-Terrestrial Networks (NTN) | 17th November 2022  Join Les Granfield on 17th November (10-11am UK time) for this live training webinar looking at 3GPP Non-Terrestrial Networks (NTN) (17 Nov) This webinar looks at how 3GPP propose to use the 5G New Radio (NR) to provide 5G cellular coverage in hard-to-reach locations such as ships at sea, airborne aircraft, trains and remote geographical locations using non-terrestrial flying objects.   The flying objects are more commonly known as satellites but the NTN will also include High Altitude Platform Systems (HAPS), Air-to-Ground Systems as well as Unmanned Aerial Systems (UAS).  Topics include: Competing commercial satellite systems...

Recorded 13th September 2022 The energy and utility sectors are going through a time of unprecedented change, driven largely by the drive for “net zero” and “smart grids”.  A shift towards renewable and more localised energy sources, coupled to a greater reliance on digital technology and automation, has transformed these industries. The sector is now actively envisioning how new wireless broadband communications technologies, and the cloud, can help them harness the power of the growing wave of connected devices and data. These technologies will replace traditional narrowband telemetry, tele-control and tele-protection systems, and enable utilities to move increased volumes of data...

Recorded: 3rd May 2022 This webinar aims to clarify why there is a requirement for more radio spectrum for 5G systems, what bands have been identified, and why, and the challenges and solutions these new bands bring.      Topics covered include: The relationship between bandwidth and bit rate The relationship between frequency band and coverage Bands identified for 5G by regulators Impact of radio channel bandwidth on spectrum allocations Impact of wavelength upon antenna dimensioning Propagation issues associated with Millimetre wave bands (mmWave) How higher frequencies facilitate the realisation of massive MIMO Impact of mmWave on device power consumption Webinar Speaker: ...

Webinar Recorded: 12th October 2021 Delivering ever-increasing data volumes to a growing customer base who are willing to accept mobile and nomadic broadband services places enormous strain on telecoms operators in terms of capacity requirements and network densification. New broadcast-based services and business models, as well as connected innovation and IoT, add to the challenges. A range of measures can be used to ease the pressure, and many have been the subject of ongoing development as part of the 4G LTE Radio. The introduction of 5G New Radio, however, has provided an opportunity to take a fresh look, optimise techniques, and,...

When planning a microwave link it is imperative to ensure there is sufficient clearance between the main bore of the radio signal and any obstacles along the radio path. There are various rules and guidelines defining what is meant by sufficient clearance - they may be set by a national spectrum management authority, in-house criteria, or recommended by a body such as the ITU-R. All of them, however, require the radio planner to apply the relevant k factor associated with the chosen clearance criteria and model. It is therefore paramount that the radio planner fully understands the function of the...
