AirGirdM and NanoBridgeM – InnerFeed Antenna

Sunday, January 3rd, 2010

Ubiquiti presented new line of devices for InnerFeed AirgirdM for 2.4gz band and NanoBridgeM for2.4 and 5gz UNII band.

AirGirdM is presented as complete airmax CPE Solutions for around  $30USD – great price if you ask me! This one is succsesor of Bullet2M and promise up to 100MB throughput so no real MIMO here.

airmax tdma

The advantages of Ubiquiti Networks airMAX TDMA MIMO technology:
– 300 + subscribers per sectored base station
– 150Mbps + Point to Multipoint speeds
– Low Stable latency responses for VoIP and Video applications as network scales

Be one of the first in the world to try the airMAX MIMO technology and place your order today and we will ship your order as soon as equipment becomes available by the end of August.

Time division multiple access (TDMA)

Technology used for example in GSM networks, Motorola Canopy, DVB, etc. This is a smart and sophisticated system sharing one frequency supporting multiple users on an accrual basis. Each of the users, who share the frequency, has a dedicated time slot. This is in very rapid succession of individual transmissions creates a transmission hannel, called timeslots, used for communication between client and base station unit (access point).

** To get full AirMax performance, all radios have to be AirMax products.

** AirMax is not compatible with AirOS 3.x or any other manufactures’ products or OS.

** Non-AirMax UBNT products and other manufactures’ products cannot be upgraded to an AirMax product.

And from http://www.ubnt.com/forum/showpost.php?p=50068&postcount=4
If you have AirMax on, and you take note of proper installations signals and fade margins, then you can reach in upwards of 100 user’s. However you must have the bandwidth to support this.
