Airmux200

1

• Airmux-200
• Update for August 2007

2
Agenda

• Symmetrical vs. Asymmetrical transmission
• HE
• HSS feature
• IDU-R
• 8 port PoE
• Wrap-up

3
Asymmetrical vs. Symmetrical

• Most TDD radios transmit and receive in a
  demand-based mode
• If there is more data to send, then they spend a
  longer time sending
• If there is more data to receive they spend a
  longer interval receiving.
• Good on papernot good for certain
  applicationsvoice and video
• Airmux is completely symmetrical
• Equal time sending and receiving every time

4
Airmux 200-Voice and Video

• Designed to transmit T1 traffic
• All transmission is symmetrical
• Standard, unframed E1/T1, compliant with ITU-T
  standards
• BER lt 1x10-11 _at_ sensitivity threshold
• Accurate clock recovery mechanism (0.05 PPM)
• Advanced clock configurations
• Patented ARQ fast retransmission

5
New- HE ODU

• High power (up to 23 dBm)
• Available in 5.8 GHz
• Supports Synchronized Co-located Units-HSS
• 4 x the transmit power
• Higher link quality reliability
• Best for areas with high RF interference

6
Collocation Challenges

• When multiple radios are installed in close
  proximity, sources of interference are multiplied

Frequency Interference Collocated units use the
same and adjacent frequencies Transmit/Receive
Interference Units transmit at the time that
other units try to receive
7
Airmux Hub Site Synchronization

• Unique burst synchronization technique
• Synchronizes Tx and Rx timing for all units at a
  hub site
• Eliminates collocation TDD interference
• Support mixture of 20, 10, 5 MHz Channels
• Enables multi point-to-point architecture

8
HSS Basic Architecture (topology)

• All collocated units are synchronized using a
  shared sync pulse
• The sync pulse is generated by a Hub Sync Master
  (HSM) ODU and distributed through sync cables and
  HSS unit to Hub Sync Client (HSC) ODUs
• A Hub Sync Client can be configured in two ways
• Hub Sync Client Continue Transmission In the
  event that the unit loses synchronization with
  the Hub Sync Master, the link remains active.
  However, without synchronization pulses, it is
  possible that this unit will cause interference.
• Hub Sync Client Disable Transmission In the
  event that the unit loses synchronization with
  the Hub Sync Master, the link is dropped until
  the synchronization pulses resume. This setting
  prevents the unit from causing interference.
• The remote ODUs that are not located at the hub
  site, are called Independent Units and do not
  require HSS hardware.

9
Hub Site Synchronization (HSS)

• Supporting up to 16 collocated units
• Requires HSS Unit, HSSU-10, and Sync cables
• Supported products
• For all ODU High End (ODU-HE) and All-Indoor
  (AIND) products

10
HSSU-10

• Passive CLK distribution unit (no power feeding)
• Full outdoor installation, typically on a pole
  next to the ODUs
• Cable connects between HSSU-10 and ODU-HE
