1W Portable TDD Transmitter with Advantages over FDD
?
?
Introduction:
?
TDD is ideally suited to the transport of asymmetric traffic, as is typical with Internet access, and it allows service providers to define accordingly the percentage of bandwidth allocated to each direction. In addition, TDD makes more efficient use of spectrum, allowing network operators to achieve greater returns on their investments in infrastructure. As for FDD, it is the scheme of choice when traffic is symmetric, as in carrier backhaul and enterprise data transfer applications.
?
Therefore, in the near term ?– as WiMAX is adopted for last-mile applications ?– network operators are advised to choose TDD in order to achieve the flexibility required for managing divergent traffic patterns.
?
Advantages over FDD:
# # Guard Band: TDD requires no; FDD requires;
# Hardware Cost: Much lower than FDD.
?
Product Features:
# # Smart, light and low power consumption
# Support system with frequency or inter frequency networking, automatic roaming
# Stable power, adjustable dynamic power
# NLOS transparent IP data and audio and video transmission
# Encryption: AES 128 bit
# Stable power supply for over 5 hours.
