DL10 10GHz DOCSIS BROADBAND WIRELESS

DL10 10GHz DOCSIS BROADBAND WIRELESS

NOTE: We no longer mass produce this equipment. DL10 is available only in low quantities for spares and repairs.

Ogier DL10 offers a cost effective solution for rural areas where ADSL or cable is neither available nor financially viable. The system operates in the 10.5 GHz frequency band and achieves high megabit data rates over ranges up to 10 km.
The system interfaces directly to Data-Over-Cable-Service-Interface-Specification (DOCSIS) equipment (the de facto world standard for IP cable systems).
DL10 allows operators the maximum flexibility in the choice of equipment manufacturers and suppliers. The system is transparent and behaves identically to cable.

Systems have been in operation since 1999 with major cable operators in Brazil, Mexico, Saudi Arabia, Denmark, Ukraine, Spain and Ireland.
The system has been tested successfully with DOCSIS 3 routers and modems.

World Standard – DOCSIS

A key feature is that the system interfaces directly to open standard routers and modems that are in use in almost every country in the world.
Many manufacturers can supply these elements, which means that all their developments are available to the benefit the network. They include upgrades of the DOCSIS specifications, Voice over IP and higher data rate operation.

Proven Turnkey Solution

The equipment has been designed to be simple and straightforward to install.
Should operators so chose, they can undertake all the installation work themselves. Indeed in Denmark, local electricians have installed Base Stations and many subscribers install their own CPEs.

Low Cost

The system is scalable from low data rates as little as 30 Mbps. This means that the infrastructure cost need only be committed when it is needed, which makes it ideally suited to meet the growing needs of a developing market.

The growth in capacity, combined with the low cost of the customer premises equipment, a fraction of that of other proprietary systems operating in the licenced bands, means that the system is so inexpensive it is affordable to residential as well as business users.
Financial models of the payback times show that it can compete head-on with fixed line systems, even if the requirement is to recover all the infrastructure costs within 18 months or less.

Base Station

The base station simply requires a router, an up-converter and a wireless transceiver with its integrated antenna and a power supply unit.  A single transceiver covers a 90-degree sector. Thus four transceivers will be required to provide full 360-degree coverage.
Multiple transceivers can be installed in any given sector if the capacity requirements are high in a particular direction.
Conversely, in rural areas where the capacity requirements can be lower, a single transceiver can be used in a slave/master hub configuration to feed two sectors. In this way only two transceivers are required for the full azimuth coverage.
A single router can provide the data processing for up to 8 transceivers serving up to 7,000 subscribers.

Subscriber Equipment

The standard DOCSIS CPE (Customer Premises Equipment) comprises a wireless module and a wall plug power supply.
The wireless modules are designed for all weather operation on standard wall mount installations. Line of sight is required to the base station.
The alignment can usually be performed by eye in all but the most critical cases.
A single 75 ohm coaxial cable connects the CPE to the power supply and DOCSIS modem.

Backhaul and Last Mile

The system is unique in that it has the capacity and the range to provide the backhaul communications between the primary Base Station and Secondary Hubs, as well as the “last mile” transmission to the subscribers.
The Base Station and the Secondary Hubs have up to four 90 degree sectors for local subscribers, and use the same antennas, transmitters and receivers to provide the backhaul. This arrangement avoids the need for an array of fixed point-to-point microwave links and in so doing, simplifies the complexity, reduces the cost and increases the reliability of the network.
All the commercial operators of the equipment use this unique feature.
