Дальность и скорость передачи данных. Теория

Зависимость потерь энергии в свободном пространстве

от расстояния и частоты

Энергетический бюджет линии связи

Бюджет связи = Мощность передатчика + КУ Антенны – Чувствительность приемника

� Мощность передатчика – максимальная мощность передатчика

� КУ антенны учитывается суммарно для передающей и приемной антенн

�чувствительность приемника – минимальная мощность обеспечивающая PER

� Бюджет связи – эквивалент допустимых потерь между приемником и передатчиком

Дальность и скорость передачи данных (важные факторы)

� Антенна (усиление, чувствительность к внешнимвоздействиям)

� Чувствительность: минимальная мощность на входе дляприемлемого качества связи (на практике 1% PER)

� Избирательность: насколько хорошо работает приемник вприсутствии помех

� Выходная мощность

� Условия эксплуатации (прямая видимость, препятствия, отражение, многолучевое распространение)

Опираясь на предыдущие теоретические данные и практическийопыт можно сформулировать несколько закономерностей:

• Практические правила:� Увеличение бюджета связи на 6 дБ -> увеличение дальности в 2

раза

� Удвоение частоты -> уменьшение дальности в 2 раза (дальностьна 433МГц выше, чем на 868МГц)

� Бюджет связи в 120дБ позволяет получить дальность около 2000 метров на частоте 433МГц (практическое правило TI)

Competitors have typically 30dB less adjacent channel rejection and blocking performance than CC1120. Interferer needs to be moved several meters away or it will interrupt the RF communication.

Энергопотребление

� Используем минимально возможный рабочий цикл

– Передаем данные только когда это необходимо, не отправляемпакетов больше чем необходимо

– Используем максимальную скорость передачи (противоречие сдальностью)

– Используем возможности оптимизации энергопотребления науровне протокола или чипа

� Используем минимально возможное напряжение питания

– У RF чипов чем ниже питающее напряжение тем нижепотребление тока

– Низкое напряжение питания негативно сказывается на RF-характеристиках (не проблема если есть встроенные LDO)

� По возможности используем импульсные DC/DC с низкимтоком собственного потребления

Why W-MBUS ? Why TI W-MBUS ?

Focus on W -MBUSTI partners with Wireless MBUS solutions

• TI have implemented WM-bus on the CC1101 , based on EN13757-4 specifications.

• Application Note with SW available on the Web – AN06 7.

• TI 3.party offers HW (module) and SW solutions with WiM-bus – Radiocrafts (CC1110), Amber Wireless (MSP + CC1101) and Steinbis TZ (SW stack on MSP430+CC1101 and CC430).

• Further HW support for WM-bus planned in future products.

• Challenging points in the standard (for modern RF transceivers with packet handling features):

– Data rate variation (T mode) : +/-10%• This is quite ”extreme” and requires extra hardware in the

demodulator to handle

• The sync word is ”non-standard”– 18,10 bit long (8*n is more common)– Sync word is NOT Manchester modulated while the dat a is
