ZTE adds new 4G LTE base station to address multi-frequency, multi-system fusion challenges

Chinese telecom equipment vendor ZTE today launched a new base station — the Ultra Broadband Remote Radio Unit (UBR) that can help operators tackle multi-frequency, multi-system fusion challenges and roll out better 4G LTE networks.

ZTE UBR includes the features such as big pipe based on ultra broadband technology for 4G and beyond, flexible power allocation and multi-band pool, smart base transceiver station (BTS) site with intelligent operation and service mode.

By using a new type of amplifier and a digital pre-distortion (DPD) architecture and algorithm, the UBR currently achieves 365MHz (1850~2170MHZ) transmitting bandwidth through a single channel. This is a first in the industry, ZTE said.

The UBR can work on two different bands: 1800MHz and 2100MHz. For each band it can support GSM, UMTS and LTE mode simultaneously. In addition, the 2 × 80W transmitting power can be  adjusted on two frequency bands, and also adjusted on three different systems: GSM, UMTS, and LTE modes, ZTE said in a statement.


The embedded SiteWeb, an intelligent maintenance solution, commissions and maintains a UBR in a tower using Wi-Fi together with a UBR commissioning and maintenance application installed on a smartphone. This improves RRU commissioning and maintenance efficiency, and reduces O&M costs for operators. In addition, the SiteWeb solution provides ambience intelligence, video applications, and other functions which add more value for operators and reflect new trends in base station features.

By using a series of advanced cooling and innovative duplexer technologies, ZTE’s UBR is the smallest and lightest product in the industry as compared with other manufacturers’ RRUs with the same transmit power. The UBR provides 2T2R (2 transmitter, 2 receiver) and 2 x 80W (transmitting power) and it is 12 litres in size and 12 kg in weight requiring only one person to install it.
