Highlights of BBU5801M
High performance
Under the 20 MHz bandwidth, when the time division duplex (TDD) time slot is adopted,
the maximum downlink rate in a single cell can reach 112 Mbps (CFG2), and the maximum
uplink rate can reach 45 Mbps (CFG0). When the frequency division duplex (FDD) is
adopted, the maximum downlink rate in a single cell can reach 150 Mbps, and the maximum
uplink rate can reach 75 Mbps. This meets the needs of high-speed transmission. Cells
Single LTE baseband process (LBP) board can support three 2T2R 20 MHz cells. Therefore,
one BBU5801M with six LBPs can support up to 18 2T2R LTE cells. The number of active
users reaches up to 400 in each cell.
High security
With the development of all-IP transmission on the backhaul networks, data faces threats
such as eavesdropping and tampering during transmission. The encryption, integrity,
and data source authentication functions of data transmission have become more and
more important. The BBU5801M supports IPv6 and Internet Protocol Security (IPSec)
features. It provides IP-based data encryption, integrity, and data source authentication
functions to prevent communication from being tampered with or eavesdropping.
Flexible deployment
Supports a maximum bandwidth of 20 MHz and a variety of frequencies. Configures the
bandwidth and frequency without changing hardware. Supports TDD and FDD time slot
to meet the needs of different application scenarios. Supports multi-site large-scale
networking, small-scale internal networking and single-site networking to provide
the most valuable solutions based on different scenarios.
High reliability
The complete software reliability design and fault isolation, data rollback, fault
monitoring, and other functions are provided to reduce service downtime and increase
system availability.
