ملاحظات: كل السرعات المذكورة هي القيمة القصوى النظرية وستختلف حسب عدة عوامل، منها استخدام الإرساليات الخارجية، والمسافة من البرج والسرعة الأرضية (مثلاً الاتصالات على متن قطار قد تكون أسوأ من تلك الحادثة من مكان ثابت). Usually the bandwidth is shared between several terminals. The performance of each technology is determined by a number of constraints, including the spectral efficiency of the technology, the cell sizes used, and the amount of spectrum available. For more information, see Comparison of wireless data standards.
