MiBOS

Donor/Remote 이미지

An optical repeater for CDMA, 800MHz LTE, 1.8GHz LTE-Advanced, WCDMA, and WiBro. It transmits the RF signals sent from each base station of telecommunications services through the donor by using optical lines. The device is used to expand coverage or enable quality call service in shadow areas. Usually the optical repeaters are installed for in-building service.


STORM

It enables an operation cost reduction and various construction environments through the concentration of the original service network.


TRIO-LM/L/M

Donor/Remote 이미지
It is a device that expands mobile phone coverage and guarantees quality call service in shadow areas through the reception, filtering, magnification, and transmission of RF signals between base station and terminal.
It provides CDMA and LTE in the 800MHz band, LTE-Advanced service in the 1.8GHz band, and WCDMA and LTE-Advanced service in the 2.1GHz band. 800MHz LTE and 1.8GHz LTE-Advanced services support MIMO.


DUO-MEN/SEN

It enhances the fast construction of the network and its efficiency by bi-directionally sending the wireless signals transmitted from the base station of the CDMA and WCDMA networks (including HSDPA) to a certain place (an underground shade area).


SPEED-DuoF

SPEED-DuoR/WF 이미지

It is a home RF repeater that enables CDMA, WCDMA, LTE, and LTE-Advanced services. In the case of CDMA, WCDMA, and LTE, the device is designed to accommodate the existing 6FA as it is.
It can be installed even in a small and enclosed space and is effective in improving call service in a shadow area. It receives a signal sent from a base station or terminal, adjusts it to a proper level, magnifies effectively without any distortion, and relays it.


SPEED-WL1.8

It is a home RF repeater that enables WCDMA and LTE-Advanced services. It can be installed even in a small and enclosed space and is effective in improving call service in a shadow area. It receives a signal sent from a base station or terminal, adjusts it to a proper level, magnifies effectively without any distortion, and relays it.


Low power RRU for 800MHz

>800M 소출력RRU 이미지

The RRU receives a base station signal from DU as an optical signal; changes it into an RF signal; and conducts signal magnification and transmission. As a result, call service coverage is expanded in a shadow area, and data throughput increases. The RRU provides LTE MIMO service in the 800MHz band.


Low power dual band RRU

The RRU receives a base station signal from DU as an optical signal; changes it into an RF signal; and conducts signal magnification and transmission. As a result, call service coverage is expanded in a shadow area, and data throughput increases. The RRU provides LTE service in the 800MHz band and LTE-Advanced service in the 1.8GHz band. MIMO support is possible in the 800MHz LTE and 1.8GHz LTE-Advanced cases.


1.8GCRU

1.8GCRU receives a base station signal from DU as an optical signal, which is digital. Then, the device changes the signal into the RF signal and expands mobile phone coverage and guarantees quality call service in shadow areas through signal magnification and transmission. It is also used for a data throughput increase. It provides LTE-Advanced service in the 1.8GHz band.


Giga WiFi Access Point

The Giga WiFi AP can be used both indoor and outdoor and supports 2.4GHz and 5GHz. It supports the 802.11ac standard (Max: 1,300Mbps) in 5GHz—which allows Giga WiFi AP to have a higher performance compared to the legacy AP. Also, Giga WiFi AP uses beam-forming technologies to provide wider service coverage.


Access Controller

The Access Controller manages and controls access points in the WiFi network and provides certain services to sites considering WiFi traffic. It also provides the inter-AP handover, subscriber-specific authentication, and QoS policy.


Cloud Access Controller
