ATDI understands efficiency and is an expert at getting the most out of radio systems
ATDI’s flexibility combines off-the-shelf software with custom solutions.
Dynamic spectrum is about maximising the efficient use of resources. This has been part of ATDI’s culture since its inception.
Dynamic spectrum management is a new field that aims to improve the overall effectiveness of a radio network. A key issue is interference and ATDI’s three-decades of experience is rooted in how to eliminate and mitigate interference problems. With interference issues mitigated, dynamic spectrum management has the potential to achieve efficiencies in both spectrum and energy usage.
By using coverage calculations and subscribers, ICS telecom EV determines where white space can be utilised and how WP devices might impact existing licensed users such as broadcasting and wireless microphone users.
ICS telecom EV allows users to manage signal propagation and coexistence scenarios enabling the best outcome and use of available spectrum. Features include:
The majority of current Wi-Fi devices operate in the 2.4GHz spectrum band. White space provides new capacity and boosts the distance a device (WSD) can be from a base station and remain connected. This allows Wi-Fi networks to stretch across towns and cities, as a result of the lower frequency of TV white space (typically between 470 and 790 MHz).
The main difference between WSD and Wi-Fi is that the white space router needs to connnect to an online database (WSDB), notify it of its location and update it on a regular basis. The database then return details of the radio frequencies available and power levels the router is can use. This will ensure that the connected device does not interfere with existing spectrum usage.
Using ICS telecom EV, a WSD operator can identify potential white space and interferes in a specific zone to complete the white space workflow and publish the data online.
Machine-to-Machine (M2M) communications allow information to be exchanged between devices. White space can be used to transmit this information over wireless, enabling the additional range to reach deep inside buildings. This is particularly useful for wireless utility meters in consumers homes, keeping an inventory of stock owned by a business or enabling scientists to conduct research by automating the measurement of different readings.
Due to the complexity and the wide range of M2M applications, ATDI has committed a team of experts to support the network planner at every stage of the project (guidelines, vendor references, planning, IT integration, system inter-connectivity, frequency resources, web services, tests, embedded SIM and module analysis, product purpose, roaming…) using ICS telecom EV and then identifying where white space might be used.
White space can be used to provide rural locations with broadband services. In practice, this could be achieved by building a network of transmitters using white space to link remote houses and villages to larger towns that are already connected to the internet.
Using the coverage calculations and P2P analysis with subscribers in ICS telecom EV, enables the user to identify areas where Broadcast (or other) systems offer no coverage on a specific channel, which can then be reused to provide broadband access.
