# Key Features⁣⁣⁣⁣⁣

**Astra Quasar** is a wireless point-to-point solution with an impressive maximal performance of up to 2,1 Gbps, a packet perfomance is up to 500 000 pps. 

**Astra Quasar** operates in frequency range from 4900 MHz to 6060 MHz for QSR5, from 6000 MHz to 7100 MHz for QSR6 and supports the channel width 20, 40, 80, 160 MHz.

### Radio <a href="#keyfeatures-radio" id="keyfeatures-radio"></a>

* **Automatic Modulation Control (AMC)** – modulation control algorithm selects the most appropriate modulation-coding scheme in order to maximize the link performance.
* **Automatic Repeat Request (ARQ)** – a technology which enables packet re-transmission in case of previous unsuccessful delivery, allows to achieve reliable connectivity even in highly congested spectrum.
* **Automatic Transmit Power Control (ATPC)** – a technology which allows to extend the life of devices and optimize energy consumption.
* **Automatic range detection** - the guard interval optimal for the actual distance is automatically determined.

### Networking\* <a href="#keyfeatures-networking" id="keyfeatures-networking"></a>

* MAC/IP filtering.
* RIPv2 / OSPFv2 /static routing.
* Tunneling (Ethernet‑over‑IP, IP‑over‑IP).
* L2/L3 Firewall.
* NAT (multipool, H.323‑aware).
* DHCP client/server/relay.
* Stacked VLAN support (Q-in-Q) avoids the limitation in the number of available VLANs (4096), which can be useful for large networks. In addition, Q-in-Q allows you to organize L2 channels within a limited VLAN list, which is widely used in provider networks and on leased communication channels.

### Quality of Service\* <a href="#keyfeatures-qualityofservice" id="keyfeatures-qualityofservice"></a>

* 17 priority queues.
* IEEE 802.1p support.
* IP TOS / DiffServ support.
* Full voice support.
* Traffic limiting (absolute, relative, mixed).
* Traffic redirection.

### Environment <a href="#keyfeatures-environment" id="keyfeatures-environment"></a>

* Operating temperature range -40 ... +60 ºС, in arctic edition: -55 ... +60 ºС.
* Dust and water protection in compliance with IP66/IP67.
* Wind load up to 160 kph - operation, 200 kph - survival.

### Power <a href="#keyfeatures-power" id="keyfeatures-power"></a>

The device has following electrical parameters:

* Consumption is up to 20 W.
* Power options: 110-240 VAC\~ @ 50/60 Hz, ±43..56 VDC.
* 802.3at support or proprietary passive PoE.
* AC/DC injector: IDU-CPE-G(24W) is included to the packing list.
