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
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.

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...).

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 .
Broadcast Coordination: ATDI implements RRC04/06 recommendations in its radioplanning and spectrum management tools.
The RRC04/06 report mainly concerns administrations belonging to the planning zone of the Radiocommunications Regional Conference for digital television and audio broadcast in the 174-230 MHz band and in the 470-862 MHz band. This zone covers region 1 (no 5.3 of radiocommunications rules) (parts of region 1 located East of the 170° East meridian and North of the 40° South parallel, with the exception of Mongolia) and the Islamic Republic of Iran.

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.
   
WiMAX network quality of service
Dimensioning a WiMAX network needs to keep in mind the user traffic demand and the applications he/she shall use so that the density of Base Stations and backbone network dimensioning can fullfil the demand.

two different ways: translate the problem into a fixed frequency analysis
or consider frequency hopping with statistical and random analysis.
Fixed Broadband Wireless Access Network
Planning for high-speed Internet services - Methodology
All too often in LMDS network design the marketers
and planning engineers (representing business requirement and technical
solution respectively) live apart, each operating with their own dedicated
software tools. GIS tools incorporating population demographics are the
preferred option for marketers with classic coverage tools used by their
counterparts. Given that such detached working cannot be efficient, this
paper postulates that, since subscribers can be uniquely specified in
LMDS, a combined approach is essential.
Ensuring the Network Meets the Requirements
The care of every emergency services radio communications
Officer is to ensure that the radio network meets the requirements of
the department as a whole. Traditionally, this has been performed in-house,
but increasingly, radio services are bought in from commercial sources,
and it is the job of the comms Officer to ensure that this network meets
the requirements without the benefit of leading the network development
activity. This leads to a new problem; how can the network performance
be assured when the people developing and managing the network are not
those who will ultimately use it, and when they may also have different
primary considerations, such as maximising profit obtained from the network?
End to End Design of TETRA Networks
ATDI have now completed
a number of TETRA network designs for emergency or "blue light"
services for both operators and integrators. All "blue light"
networks have similar themes beginning with the definition of requirements
and ending with verification that the network performs as designed. This
short article discusses the design steps necessary.
