Wireless Bridges

Businesses looking to create a Local Area Network (LAN) across multiple buildings on one site often face heavy costs. Digging channels to lay fibre in business parks or across public highways or even their own private land can be massively expensive. So whilst terms like Laser Links and Wireless Bridges might sound costly, they are often a very cheap alternative to laying fibre connections.

A typical example of this might be a customer looking to connect three buildings in a business park together so that the three buildings can share the same network and data facilities that are housed in only one of the buildings. The cost to lay fibre between these three sites  can often run in to tens of thousands of pounds and mean huge disruption during the process. A laser communication device on each of the three buildings will create a data link offering up to a massive 10 Gbps with 100 Mbps radio wireless links an effective back up:

The equipment Bluecube use for these Wireless Bridge solutions varies depending on a site survey. However our preferred solution uses the following technology:

LigoWave 180Mbps PTP Wireless Link

LigoWave unleashes its highest capacity, license-free PTP device with the release of the LIGOPTP 5 MIMO series product line. Making use of ground breaking 2x2 MIMO technology, the LigoPTP 5-23/5-N MIMO delivers aggregate TCP throughput capability of up to 200Mbps (100 Mbps full-duplex) combined with high packets-per-second performance.

This product enables carrier-class point-to-point capability, ideal for dedicated access or backhaul applications (including VOIP or other small packet applications). The LigoWave PTP product family couples flexible channel width capability (20 or 40 MHz) and industry-leading proprietary software mechanisms to set the utmost standard in spectral efficiency. The LigoPTP 5-23/5-N MIMO product features an integrated dual-polarized antenna (or 2 N-type connectors for the 5-N product) and is housed in a rugged, cast aluminum enclosure. Combining digital signal processing, dual polarization antennas and proprietary W-Jet protocol these bridges have a high spectral efficiency of 7.5bit/Hz.

The LigoPTP 5-23/5-N MIMO showcases an array of advanced software mechanisms that provide optimal point-to-point connectivity for high-throughput, long distance links. LigoWave’s proprietary PTP mechanisms utilize techniques such as Dynamic Time Division Duplexing (TDD) to dynamically allocate bandwidth in the direction needed, thus increasing link efficiency and greatly decreasing the impact that distance has on throughput of the link. The LigoWave point-to-point products also feature selective repeat ARQ technology, an enhanced error-correction software mechanism that optimizes data traffic to provide very high throughput over high-bandwidth, long-range links even in the presence of interference.

The LigoPTP 5-23/5-N MIMO is also compatible with LigoWave online link calculator and RCMS, a centralized configuration, firmware, and statistics server offered by LigoWave for carrier class diagnostic and configuration. W-jet is Ligowave‘s proprietary wireless protocol that combines special techniques to achieve great performance and reliability even over long distances. The W-jet protocol is the result of years of development and gives Ligowave PTP products the ability to outperform other products on the market while simultaneously optimizing ROI for the customer.
