Что такое Мобильный Бэкхолинг

• Что такое мобильный бэкхолинг?

– Транспорт между базовыми станциями и узлами концентрации.

• Backhaul сдается в аренду большими операторами?

– Единица стоимости - канал

– 20-30% сетевого OPEX

• Backhaul сейчас

– В основном Е1 и Т1

– Соединения часто идут через несколько сайтов

– Современные сервисы дошли до уровня, когда оптика уже необходима.

Mobile Backhaul


Миграция на Mobile Backhaul

• Феноменальный рост мобильных абонентов

• Значительное увеличение пакетного трафика в мобильных сетях

• Большая часть трафика терпима к задержкам

• Сети Ethernet предлагают большую пропускную способность за меньшие деньги

• Традиционные сети TDM имеют существенные ограничения по масштабируемости

• Операторы беспроводных сетей интересуются мобильным бэкхолингом как альтернативой TDM

• CAPEX и OPEX у Ethernet существенно меньше

Timing

• Note that market requires all of the following timing options:

• IEEE 1588v2 PTP

• Synchronous Ethernet

• T1/E1 (using Pseudowire)

• GPS using BITS interfaces

• E4G Products provide ALL of these options to fit any network demand

• EANTC September 2011 Update

• SyncE testing was perfect – no issues, no learning curve, no troubleshooting

• Our 1588v2 PTP implementation was accurate within 1 microsecond even after 12 hours of impairment (delay & jitter)
