The Importance of a Site Survey

In radio network planning projects it is more of a rule than an exception that the given site coordinates are inaccurate compared to the resolution of the underlying terrain database. If inaccurate input data is entered into the radio network planning software, the resulting output will also be inaccurate. Garbage in, garbage out! The purpose […]

How do you reach the full potential of your SFNs?

In large SFNs, where the transmitter separation distances exceed the selected guard interval length, self–interference zones might occur within the required service area. These zones might have a very strong negative impact on the network coverage probability. The network planner can apply several different approaches to mitigate the negative effect of the self–interference zones. The […]

A Simplified Description of Coverage Probability Calculations for OFDM Systems in Radio Network Planning Software

Orthogonal Frequency Division Multiplexing (OFDM) is a technique that is used in many popular wireless communication systems, such as digital terrestrial broadcast systems (DVB-T, DVB-T2, ISDB-T, DTMB, CMMB, T-DAB, T-DMB), wireless LAN, WiMAX, and LTE. OFDM works very well in radio channels where multipath propagation is particularly noticeable. Multipath propagation generates mainly two effects: intersymbol […]
