Dubai may wait until GBAS (ground based augmentaion system) is available. If it is a signal interference problem, then GBAS will eliminate it.
GBAS uses GNSS signals, detects any errors then transmits a signal to the A/C GPS receivers. Accuracies are typically less than 2m.
GBAS will come in CAT I, CAT II and CAT IIIa, b, c AND d. CAT IIId will have the ability to taxi the A/C to the gate!
