# Key Features⁣⁣⁣⁣⁣⁣⁣

Astrawireless Evolution is a wireless point-to-point and point-to-multipoint solution with an impressive maximal performance of up to 800 Mbps. It operates in 5 and 6 GHz frequency ranges: from 4900 to 6425 MHz and supports the channel width 20, 40, 80 MHz.

**Base Stations can be used with:**

* a dual polarization integrated antenna with an antenna gain 16 dBi and 21 dBi;
* an external antenna connected to two N-type ports using low-loss RF cables.

**Subscriber terminals and PTP devices can be used with:**

* a dual polarization integrated antenna with an antenna gain 18 dBi, 23 dBi, 25 dBi and 28 dBi;
* an external antenna connected to two N-type ports using low-loss RF cables.

and operates in LOS and non-LOS conditions. OFDM radio technology is used for data transmission.

### 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 an extended temperature range: -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 for base station sectors ( 30W for E5-BSQ) and up to 15 W for subscriber terminals.
* Power options: 90-240 VAC\~ @ 50/60 Hz, ±43..56 VDC.
* 802.3at support or proprietary passive PoE.
* AC/DC injector:
  * IDU-CPE-G(56W) is included to the packing list of E5-BSQ model.
  * IDU-CPE-G(24W) is included to the packing list of all other models.
