Fast deployment
The eLTE Rapid adopts the box-type design and supports fast deployment by eight steps within 15 minutes.
The eight steps for deploying the eLTE Rapid are as follows:
1. Open the front and rear covers.
2. Remove the protection cover of the main box.
3. Open the protection cover of the RRU box.
4. Use optical cables to connect the RRU and BBU.
5. Connect the RRU power cable.
6.Connect the power supply of the main box.
7.Connect the RF cable.
8.Start the system.
Selection of an antenna box and installation of on-board accessories are not counted into the above procedure.
High mobility
You can move the eLTE Rapid on rollers or hump the eLTE Rapid.
All products are gathered in boxes, the CN device and the baseband device are integrated, and the NMS in the PC edition is used.
The casters mounted to the bottom of the boxes enable the eLTE Rapid to be dragged by a person as a whole. You can also hump a single box or drag it using the casters on the bottom. Each box weights properly and the barycenter setting prevents the stack of boxes from damaging devices inside. In addition, the tightly fixed handles facilitate the movement.
High integrity
The eLTE Rapid features high integrity in a compact structure, which combines the base station, CN device, dispatcher, RF device, antenna, power supply device, and on-board accessories in a modular manner for the fast deployment purpose in disaster relief events or emergencies.
High adaptability
The eLTE Rapid can operate without supply mains, for example, in a field environment. A main box and a power supply box can work properly without any shield for about two hours in light rain or breeze. The RF box and the antenna box can work properly in a rainy weather for a long time.
Multiple transmission means
The eLTE Rapid supports satellite, radio, wired network, and other transmission means to exchange information with the outside.
Various professional trunking functions
The eLTE Rapid provides all functions of a enterprise network fixed station, which supports professional trunking, massive narrowband data, and HD video transmission.
Product Overview
The eLTE Rapid adopts a box-type structure, which consists of at least one laptop and two boxes, that is, the main box and the RF box. The laptop runs the eOMC in the PC edition and the eDC. The main box contains the eSCN231 and eMDC devices and the RF box contains the eRRU.
The eLTE Rapid system can also be equipped with a power supply box, on-board accessories, and an antenna box. A power supply box can feed power to the eLTE Rapid system for at least two hours. The on-board accessories are mainly components for installing the eLTE Rapid on a vehicle. The antenna box contains an antenna support and an antenna for installing the antenna in non-vehicle scenarios. The antenna support is a retractile pole up to 2.5 m long. The antenna height is 3 m taking the antenna length into account.
The eLTE Rapid uses a modular design for easier installation and deployment, and applies to communication in static state, communication in motion, and non-vehicle scenarios.
The eLTE Rapid adopts the shockproof design to prevent equipment from damage in transportation. The box-type design of the eLTE Rapid allows flexible configurations and applications. Therefore, the eLTE Rapid is cost-effective.
