AERO powers Greenisis Network in Bahrain under extreme heat and humidity conditions

Greenisis is the first operator to provide a green Mobile Broadband Wireless Access (MBWA) in Bahrain and is pioneering operations in the GSM guard bands.

With AERO, 3Roam was able to provide a 100% outdoor network set-up thanks to AERO's integrated Gigabit switch, combining on the roof-tops of Bahrain the traffic of each base-station with the traffic backhauled from the all other remote locations.

AERO has also been offering first-class network uptime even though Bahrain's climatic conditions are one of the most difficult transmission environments on earth (up to 50°C, 90% humidity and heavy sand winds). Furthermore, due to Bahrain's congested spectrum, the entire backhaul network has to operate in the least favorable 38GHz bands.

George El-Aily, CEO of Greenisis explains why he selected AERO:
"We are very satisfied with 3Roam's products quality and the superior network uptime they provide. AERO's Gigabit switch really made a difference, speeding-up our deployment and keeping our rental costs very low.”.

Best in class radio and header compression
Since licensed bands come at a cost, we help minimize cost per Mbps by:

  • providing best in class modem technology, enabling superior spectral efficiency and maximum radio usage

  • removing unnecessary packet information through header compression

Header compression basics
AERO Duo's header compression technique helps increase packet capacity of the link even beyond the maximum radio capacity: shrinking packets while they are transported over the air helps increase capacity from 366Mbps (radio capacity) up to 425Mbps.

As packets have different size (from 64 to 9200 Bytes), header compression's effect varies depending on actual traffic type. But capacity achieved for typical Internet traffic averages 395Mbps.

The graph shows you exactly the capacity you will get from an AERO Duo link, depending on packet size.

Maximum transmit power (dBm) - Aero vs. other outdoor product

Why compromise on link distance and availability when going outdoor?

AERO Duo uses high-power radios with up to 30 dBm power to handle most challenging radio configurations with ease. It provides from 6 to 12 dBm more power than other outdoor equipments.

Since 6 dBm difference means a 4x RF power increase, AERO Duo makes it possible to reduce antenna size by at least one step. It drastically impacts hardware costs, but also significantly reduces rental costs of co-located sites.

This graph shows AERO Duo's maximum radio power compared to a well-known competing full-outdoor product. The additional power gives also an increased link stability and ensures best uptime for your network.

Adaptive Power Control provides receive signal stability 1. Adaptive Power Control provides receive signal stability

Adaptive Coding increases data redundancy to protect transmission 2. Adaptive Coding increases data redundancy to protect transmission

Adaptive Modulation decreases modulation to protect connectivity 3. Adaptive Modulation decreases modulation to protect connectivity

AERO Duo's robust radio integrates Adaptive3 radio technology for maximal link availability and traffic protection.

Adaptive3 radio combines 3 levels of protection to adapt to ever-changing radio conditions:

  • Adaptive Power for optimum local (ATPC) and remote (RTPC) power management.

  • Adaptive Coding.

  • Adaptive Modulation.

Using those 3 techniques at the same time, AERO Duo reconfigures its radio on-the-fly (hitless configuration) and maximizes link availability to guarantee the highest network uptime.

Top-priority traffic remains untouched, thanks to the combination of a 4 queue Quality of Service management system preventing loss of high-priority data.

Maximize spectrum usage with Header Compression

Several protocols are stacked on top of each other to ensure the seamless communications between applications and servers. While applications deal with resource intensive TCP or UDP protocols, heavy-lifting transmission equipment such as AERO Duo interact at the Ethernet level.

Ethernet is today used for the fast and efficient transport of huge amount of information within a transport network.

AERO Duo processes Ethernet frames and is capable of removing unecessary or unused information from each frame. This technique is called Header Compression. Thanks to Header Compression, a wireless connection using AERO Duo is capable of transporting more traffic than the theoretical capacity of the radio link.

How Aero duo compress headers
Of course, AERO Duo's powerful packet processor is capable of performing this operation without altering nor slowing down Ethernet traffic.


Since Ethernet headers have a fixed length, compressing Ethernet headers does have more impact for shorter frames of 64, 128, 256 or 512 Bytes. Therefore the effect of Header compression is dependent of the type of traffic going through the link.

However, in case of typical Internet traffic, a majority of frames smaller than 512 Bytes is transported, showing an average link capacity of around 500Mbps.
