Point-to-Point Broadband Wireless

Motorola makes it easy to backhaul or extend your network wirelessly.

Motorola's high-performance, point-to-point radio solutions operate in many frequencies, providing reliable connectivity when and where you need it, even in the most challenging environments.

As enterprises extend their networks beyond the confines of walls and buildings, point-to-point, wireless Ethernet systems have become more widely utilized to bridge IP traffic – especially across spaces that are too difficult or too expensive to bridge with wires. Whether the requirement is to link separate loops within individual buildings, communicate between buildings or link networks in a campus setting, enterprises increasingly turn to wireless Ethernet as the preferred solution.

Analog Versus IP

Increasingly, enterprises choose to bridge IP traffic with microwave rather than to lay new cables or incur monthly leased-line charges. They also prefer a native IP infrastructure end-to-end, rather than converting to circuit-switched technology just to cross an air gap. Plus, they favor the speed of digital, multi-megabit performance over T1 data rates on analog networks. This decision to remain digital end-to-end offers several clear-cut advantages:

• Reduced infrastructure complexities
• Lower equipment cost
• Ability to overcome path obstructions
• Higher throughput

Wireless Ethernet in particular offers enterprises reliable, secure multi-megabit speeds with significantly better performance than the T1/E1 data rates of analog networks.

Licensed and Unlicensed Wireless

The decision to adopt a wireless Ethernet bridge brings with it another decision: whether to operate in the licensed or unlicensed space. Both have their advantages. However, the ideal solution would be to enjoy the advantages of both, or what might be called, “licensed performance in the unlicensed space.” Licensed Ethernet operates within the part of the radio spectrum (e.g., 6.0 GHz in the U.S.) designated by government regulators to be reserved for individual license holders. Licensed operators are permitted exclusive use of part of the band over an assigned geographic area. With exclusive rights, an operator should be able to operate without interference or spectrum crowding caused by other operators transmitting in the same frequency band, in the same geographic area. Less interference should translate into higher throughput – i.e., better link performance.

Speeding without a License

Motorola's Point-to-Point Wireless Ethernet Bridges – PTP 400 and PTP 600 Series – were designed with performance and reliability in mind. First, they are very fast bridges with models that can deliver up to 300 Mbps aggregate throughput. However, by itself, speed is not necessarily a solution for spectrum crowding. As an analogy, a runner's ability to run fast may not help much if other racers block the lane.

Orthogonal Architecture

Each Motorola-enabled point-to-point link employs multiple signals between two bridges on opposite ends of the air gap, each of which is connected to two antennas. One antenna on each end is oriented to polarize signals in the vertical plane while the other antenna polarizes signals in the horizontal plane. On the receiving end, each antenna receives two orthogonal signals – i.e., two signals oscillating at right angles to each other.

This architecture, combined with the following technologies, creates a number of mutually reinforcing advantages with respect to performance, reliability and spectrum management:

• Multiple-Input Multiple-Output (MIMO)
• Intelligent Orthogonal Frequency Division Multiplexing (i-OFDM)

Multiple-Input Multiple-Output (MIMO)

Through the use of MIMO technology, the PTP 400 and PTP 600 radios radiate multiple beams from the antenna. Having multiple beams from which to sample data greatly increases the probability that at least one of these beams will succeed. Conversely, the probability of failure is reduced by the same degree; so this technique allows a higher data rate than if only a single path was used. It assumes that the sampling algorithm only makes a simple decision to sample whichever of the four signals happens to be the strongest. An even lower failure rate – and correspondingly higher data rate – is achieved if data from all beams are sampled (even the weakest) and the signal reconstituted. This is what happens in the Motorola PTP 400 and PTP 600 Series bridges.

Motorola provides a comprehensive portfolio of best-of-breed wireless broadband solutions that enable enterprises to deploy the most advantageous system to meet their individual connectivity requirements. Available as stand-alone solutions or integrated with Motorola's point-to-multipoint and Mesh products, the PTP 400 and PTP 600 point-to-point wireless Ethernet bridges deliver the reliable, secure and high-bandwidth data, voice and video traffic that enterprises require for applications, such as:

• Building-to-building connectivity
• Replacing or augmenting T1/E1 lines
• Network redundancy
• High-bandwidth connectivity for Voice-over-IP, distance learning and video surveillance

The success of these products results from Motorola's unique combination of technologies, the overall effect of which is much more powerful than using any of them individually. The key advantages of these technologies include:

• Ability to overcome path obstructions
• Reliable, high-throughput communications
• Multi-layered security
• Reduced infrastructure complexities
• Choice of configurations - 10/100/1000 Base T, 1000 Base SX, single or dual T1/E1, DS3, OC-3
• Fast, easy installation and management
• Fast return on investment – typically less than one year
