ATDI: helping Norway maximise spectrum resources (LTE coexistence case study)

As part of its preparations for an auction of slots in the 790-862 MHz range, Norwegian spectrum regulator NPT asked ATDI to identify any potential interference problems involving this band and those adjacent. It was essential that NPT was extremely clear about what spectrum was to be sold and what the frequency
slots in it would do. Like all regulators, NPT operates under a number of strictures: its political mandate, the demands of the potential buyers of the spectrum, the responsibility that comes with dealing with purchase prices in the many millions, and the need to avoid post-auction complaints from operators that their services are suffering from interference.

NPT turned to ATDI to carry out the exacting task of planning and modelling with sufficient accuracy to meet all these demands.
Specifically, ATDI assessed the potential impact of an LTE mobile network on public service television broadcasts. The company analysed how an LTE system in the 800 MHz band would affect the existing UHF networks using the Digital Video Broadcast Terrestrial system (DVB-T).

Download ATDI' latest case study in order to find out how to identify and avoid potential interferences and ensure smooth coexistence when planning LTE network.
Human Exposure and FCC-OET-B65 MPE Compliance Calculations

ATDI releases a new white paper that follows the article originally written by ATDI – Sami Nedhif in May 2008 introducing ICS telecom’s capabilities for calculating Health safety and Field Strength Exposure. This paper is in response to the high volume of enquiries that the original article generated requesting clarification on the compliance calculations referenced by the FCC Guidelines described in the OET Bulletin 65. This article describes the methodology used in ATDI software tools to quickly prepare a rooftop CAD project, and an MPE analysis.
A proper MPE analysis requires all the standard components of a fully featured RF Planning tool like ICS telecom plus dedicated functionalities and user customizing capabilities. The ATDI suite of tools streamlines the process and imports the information provided from a CAD drawing in a user-friendly manner easy to replicate repeatedly. No training is required.

Mobile LTE network design with ICS telecom

Currently, UMTS networks worldwide are being upgraded to High Speed Downlink Packet Access (HSDPA) in order to increase data rate and capacity for downlink packet data. In the next step, High Speed Uplink Packet Access (HSUPA) will boost uplink performance in UMTS networks.
However, in order to ensure the competitiveness of UMTS for the next 10 years and beyond, concepts for UMTS Long Term Evolution (LTE) have been investigated. The objective is a high-data-rate, low-latency and packet optimized radio access technology. This white paper describes the main features of the LTE concept and how these features can easily be handled by ICS telecom. Today, the ICS telecom software is able to provide a full solution for the LTE network design as well as for the coverage simulations, interference and traffic analysis and regarding the MBMS (Multimedia Broadcast Multicast Services) network management.

General considerations in WiMAX technologies

WiMAX™ is based upon the IEEE 802.16 standard enabling the delivery of wireless broadband services anytime, anywhere. WiMAX products can accommodate fixed and mobile usage models. The IEEE 802.16 standard was developed to deliver non-line-of-sight (LoS) connectivity between a subscriber station and base station with typical cell radius of three to ten kilometers. All base stations and subscriber stations claiming to be WiMAX compliant must go through a rigorous WiMAX Forum Certified™ testing process. WiMAX Forum Certified systems can be expected to deliver capacity of up to 40 Mbps per channel. This is enough bandwidth to simultaneously support hundreds of businesses with T-1 speed connectivity and thousands of residences with DSL speed connectivity. The WiMAX Forum expects mobile network deployments to provide up to 15 Mbps of capacity within a typical cell radius of up to three kilometers. WiMAX technology already has been incorporated in notebook computers and PDAs to deliver high speed mobile Internet services anytime, anywhere.

ICS telecom can easily manage Over Subscription Ratio (OSR) as a criterion for the design of a network

The OSR is the ratio of the total subscriber’s demand over the reference capacity of the base station when taking into account the adaptive modulation. The reference capacity of the base station corresponds to the available bit rate of the lowest modulation.….

Mobile WiMAX - From OFDM-256 to S-OFDMA

The management of different duplexing modes, AAS, and service flow provisioning (among others...) are already included in the d-2004 standard, and new items such as OFDMA sub-channelization techniques, hand off sessions and management of MBS have to be supported to be compliant with the e-2005 version. WiMax evolves from OFDM-256 FFT to S-OFDMA, so must radio network design methodologies.

Mesh networks with ICS telecom

This white paper addresses the problem of efficiently planning mesh networks with ICS telecom. This document is intended to help a radio-planner, technical director, project manager, or consultant to be more aware of the important goals to pursue when planning large scale mesh networks in urban environments. It proposes innovative ways to accurately manage large areas of interest, using cartographic data with mixed high and medium resolutions.
The radio-planning of mesh networks can be divided into three main topics:
Dimensioning the mesh node distribution in order to achieve the requirement of coverage of the end user,
Analyzing the linkage of the Mesh Nodes, in order to optimize the dynamic routing and therefore ensuring high throughput,
Backhauling the gateways (Microwave links, WiMax...). Read the entire White Paper

This white paper addresses the problem of potential health risks of radiofrequency electromagnetic fields emitted by cellular networks (GSM, UMTS, WiMAX, Wifi…) in outdoor and indoor environments. This document is intended for radio-planner, technical director, project manager, authorities, expert responsible for population electromagnetic radiation safety, national regulators, scientists, government officials and industry representatives….Read the white paper
The WiMax technologies with ICS telecom : Fixed, Nomadic and Mobile

ICS telecom can not only deal with fixed and nomadic WiMax networks, that have heavily being tested and deployed all over the world, but it also provides all dedicated planning features for mobile WiMAX! Since the early ratification of the 802.16e standard by IEEE, WiMAX becomes eventually mobile, enabling roaming between cells.
A very easy to use workflow for the design of WiMAX networks has been built with ICS telecom and is further described in three parts:
• How the coverage model can help in dimensioning a WiMax network.
• How the capacity model will ensure that the WiMAX BS won't be overloaded due to the traffic requests of the CPEs or Mobile Units.
• How the spectrum model will minimize the interference areas, and update the achievable traffic in the designed WiMAX network.
• The whole process is described in details in this White Paper
Broadcast Coordination: ATDI implements RRC04/06 recommendations in its radioplanning and spectrum management tools

Signal propagation model in urban environment

When working with ICS telecom to simulate wireless propagation in an urban environment, a user must make the following key decisions: the selection of a type of cartographic data input (medium or high resolution data), the selection of a proper propagation model (empirical, deterministic using 3D ray tracing or not), determination of a type of technology to simulate (OFDM enabled or not, Outdoor to Indoor).
This White Paper highlights all of these propagation aspects in an urban enviroment.
