LTE Band 2 (1900 MHz PCS) and Band 4 (1700/2100 MHz AWS) B2/B4 dual-band repeater amplifier for GSM/3G/4G signals

Product Definition:

A wireless signal relay device supporting LTE Band 2 (1900 MHz PCS) and Band 4 (1700/2100 MHz AWS), designed to amplify and forward GSM/3G/4G signals for enhanced network coverage.

Frequency Bands:
– Band 2 (Uplink: 1850-1910MHz / Downlink: 1930-1990MHz 1900 MHz PCS): Supports 2G (GSM), 3G (UMTS), and 4G (LTE) services, widely adopted across North America.
– Band 4 (Uplink: 1710–1755 MHz / Downlink: 2110–2155 MHz AWS): Optimized for 4G LTE deployment, offering balanced penetration and capacity performance.

Key Features:
– Simultaneous amplification of both B2 and B4 signals
– Ideal for multi-network coordination or indoor coverage supplementation
– Compatible with carrier deployments (e.g., Verizon, AT&T in North America)
– Note: 5G NR support requires explicit configuration (e.g., n4/n66)

The B2/B4 dual-band repeater refers to a wireless signal relay device that supports LTE Band 2 (1900 MHz PCS) and Band 4 (1700/2100 MHz AWS), used for amplifying and forwarding GSM/3G/4G signals. It is commonly deployed in network coverage enhancement scenarios in North America and regions utilizing AWS spectrum. ‌‌
Band 2 (1900 MHz): Primarily used for 2G (GSM), 3G (UMTS), and 4G (LTE) coverage, belonging to the PCS band;
Band 4 (uplink 1710–1755 MHz / downlink 2110–2155 MHz): Belongs to the AWS band, widely used for 4G LTE, with good penetration and capacity balance;
Dual-band design: Capable of amplifying both B2 and B4 signals simultaneously, suitable for multi-network collaboration or indoor distribution blind spot compensation deployed by carriers (e.g., Verizon and AT&T in North America). Does not support 5G NR (unless explicitly stated as supporting n4/n66, etc.);
Typical Applications: Weak coverage areas such as underground parking lots, building edges, and rural regions. These areas utilize passive or digital repeaters, reusing the capacity of the main base station without increasing spectrum resources;

Typical Applications: Effective in addressing weak coverage scenarios such as underground parking facilities, building perimeters, and rural areas—leveraging passive or digital repeater technology to extend main base station capacity without additional spectrum allocation.
