Native TDM & Native Ethernet
Every Exalt radio system is able to transport both TDM and Ethernet in their native modes.

Capacity Aggregation
A single radio channel can only support a certain level of throughput. If more capacity is needed than the available channel bandwidth and modulation can support, more than one channel must be used. Exalt's unique Ethernet capacity aggregation technology allows the Ethernet traffic from up to four Exalt radio systems of any configuration and any frequency to be combined over a single GbE port.

Adaptive Modulation
Modern IP/Ethernet networks include built-in mechanisms to recover dropped data packets. That means that unlike TDM networks, IP/Ethernet networks can operate at a lower level of availability, e.g. 99.9% instead of 99.999%, and still operate reliably. That flexibility means that microwave links can be designed to operate at higher capacity or over longer distances or using smaller antennas than they would if the traffic consisted of TDM only. The key to reaping these benefits is adaptive modulation.

Semi-protected Operation
Microwave link protection has traditionally come in two flavors: non-protected (1+0) and protected (1+1). Protected systems provide full redundancy in the event of any failure of the primary equipment for a price of 1.6x to 2.1x the price of a non-protected system. In practice, most equipment failures occur in the active electronic components of a radio, not the passive electronic components. That means that 1+1 systems provide redundancy for a lot of components that are unlikely to fail. Exalt's semi-protected "1.5+0" option strikes the perfect compromise between protection and price.

CarrierTDD™
CarrierTDD™ technology enables Exalt time-division duplexing (TDD) radio systems to deliver carrier-class system performance to organizations of all types. For service providers -- which have traditionally relied on frequency-division duplexing (FDD) systems -- CarrierTDD™ delivers true carrier-class operation with system efficiencies possible only with TDD technology. For enterprises that have traditionally relied upon best effort TDD systems based on Wi-Fi™ technology, Exalt's CarrierTDD delivers a whole new level of performance.

CarrierTDD™ includes the following capabilities and features:

  • Guaranteed throughput at any packet size over time for engineered links;
  • Guaranteed throughput at any packet size over distance for engineered links;
  • Low and constant latency for any packet size; and
  • Monitored Hot Standby (MHS).

For a complete description of TDD and FDD, see TDD & FDD Explained.

Interference Management
The presence of potentially interfering signals is a fact of life in all radio communications, whether that communication is occurring over licensed spectrum or over license-exempt spectrum. In addition to installation techniques such as antenna selection and positioning that are used to mitigate the effects of interference, Exalt offers a range of features and capabilities that serve to minimize the likelihood that other RF signals will interfere with the reliable operation of a microwave path.

ExaltSync™
Network designers often face a requirement to collocate multiple radio systems at a single site. Such a configuration is commonplace, for example, in situations where a “hub” location serves as the termination point for multiple microwave paths. Applications such as mobile backhaul, IP backhaul and video surveillance depend on such configurations in order to meet transmission requirements.

Throughput Symmetry Control
Applications such as video surveillance, storage area networking (SAN) and Studio to Transmitter (STL) broadcasting are characterized by highly asymmetric data traffic. For such applications, Exalt’s TDD radio systems are ideal because they optimize the available channel capacity to ensure the best performance.

Software Configurability
Exalt radio systems are fully software configurable, providing the following benefits:
- Unprecedented control
- Pay as you grow capability
- Simplified sparing and operations

TDD and FDD Explained
Frequency-division duplexing (FDD) is a method for establishing a full-duplex communications link that uses two different radio frequencies for transmitter and receiver operation. The transmit direction and receive direction frequencies are separated by a defined frequency offset.
