High-Quality, Always-On Connectivity

With our fiber sDAS, Wave-In effectively reduce mobile signal dead spots caused by insufficient base station coverage, buildings or electromagnetic signal interference.

Indoor Coverage

Wave-In sDAS

Our inhouse designed Fiber-based Slim Distributed Antenna System (sDAS), can help extend RF signal coverage into any indoor environment, including basement, elevator, parking lot, and high-rise building, providing indoor 3G/4G/5G coverage services.

An In-Building Coverage Solution Suitable for Any Gth

Wave-In provides a fiber based active DAS solution for indoor signal coverage, solving the inefficiencies of passive DAS. Under 3GPP 5G NR standards, 5G use high frequencies (3.4-3.7GHz; 24-28 GHz), presenting challenges for in-building coverage due to its low indoor signal penetration rate. 

Wave-In utilize optical fibers, which can support any frequency including 3.5GHz, 25GHz transmission, and reach a distance of more than 5km. Fiber also don’t have any frequency loss, meaning the antenna can maintain a specific amount of transmission.

Traditional passive DAS cannot meet 5G’s large bandwidth requirement, which require higher antenna arrays e.g. 4T4R and is expensive. With fiber transmission and MIMO (Multiple Input & Multiple Output) beamforming, we can now support 5G indoor coverage.

Traditional DAS doesn’t support remote monitoring, while our solution have Web GUI web page management interface and can support NB-IOT, making real-time equipment status monitoring painless and easy.

Passive DAS requires coaxial cables and splitters to be fixed, and its EIRP is small, requiring more antennas for coverage, leading longer deployment times. While Wave-In’s Fiber is small in size and convenient for cabling, and the RAU’s strong signal can cover large distance, deployment time vastly shortened by 2/3.

sDAS Specifications and Key Features

Head-End Unit

HEU is connected with BTS RF head and transport signal to RAUs via single fiber. The HEU can convert RF signal from any source like Macro/Pico/Small Cell/Repeater and distribute the signal to RAUs in different locations via optical fiber.

Remote Antenna Unit

RAU extends the RF signal through fiber. RAU can be installed hidden, mounted on walls or ceilings with build-in or external antenna. Each HEU can convert and distribute the RF signal to max. eight RAUs at a 3 miles distance.

Below are the key features of Wave-In’s Fiber sDAS.

Multi-Band & Multi-Operator

Flexible to select four desired combination of operators and frequency bands. S-DAS II supports 3G/4G/5G.

Multiple Signal Source

Supports various types of input signals from base transceiver station (BTS), macro and small cell, and repeater.

MIMO

Single fiber MIMO support on both FDD and TDD model and reduced cost for maximal performance.

Star Topology

Hybrid topologies offers the most flexibility for installation under all circumstances.

One-Button Calibration

Rapid deployment with confidence in the field with the use of our auto calibration tool.

Fiber Optics

Optical fiber have longer transmission distance, can overcome signal loss and decrease installation time.

We Extend Wireless Communication To Where You Need

Wave-In’s sDAS is suitable in various environments, particularly in sites where installations are difficult. Examples include high-rise buildings, department stores, factories, hospital operation rooms, elevators, basements and parking lots.
