Nokia MetroHopper

Nokia MetroHopper Radio is a wireless access link using the 58 GHz frequency for reliable transmission. part of the Nokia MetroSite capacity solution, this radio provides access to Nokia MetroSite base Stations in dense microcellular networks. Compact and unnoticeable, Nokia MetroHopper Radio enables a veriety of new site locations and can eliminate the costly delays associated with traditional cellular transmission.

Nokia MetroHopper Radio enables same-day base station (BTS) access using the 58 GHz frequency band, which does not require coordinated frequency planning. Because the band is self-regulating, delays caused by frequency license applications or waiting for leased lines ate completely eliminated. This allows you to more easily synchronise network roll out and avoid the wasted investment of base stations lying idle on-site clue to transmission delays.

In the Nokia MetroSite solution, the indoor unit of Nokia MetroHopper Radio is fully integrated in the Nokia MetroSite Base Station cabinet and the outdoor radio unit includes a small, flat panel antenna. The radio and BTS ate connected using a single Nokia Flexbus cable, allowing fast and simple installation.

Truly affordable access

The integrated, rectangular flat panel antenna makes the Nokia MetroHopper Radio so bard to spot in the urban environment that it can be deployed in locations unreachable for conventional microwave radios.
And weighing only 3 kg, the outdoor unit is quick and easy to install. Together the unobtrusive design and compact size help to cut the cost of network implementation by contributing to simplified site selection, which may enable mass site acquisition.

Compared to the cost of leased line transmission, Nokia MetroHopper Radio is simple and cost-effective to install and operate, making microcellular network access truly affordable.

Reliable access improves network availability

Because this radio uses the 58 GHz frequency, it takes advantage of the band's unique characteristic of high oxygen absorption. This allows very high reuse of the same frequency, so you can establish hundreds of transmission access points per square kilometer. And because it is based on proven microwave technology, Nokia MetroHopper Radio offers reliable transmission access, regardless of chmate, as well as high mean firne between failure performance and loop protection. The Automatic Channel Selection Procedure selects the best channel for transmission during initial set-up of the radio relay, reducing the need for on- site configuration.

Access service provided by Nokia MetroHopper Radios also can be deployed easily from existing Nokia Talk-family Base Station sites with a base station integrated RRIC indoor unit. This offers a cost-effective way to maxinuse the usage of existing sites. Another option is to use the FIU 19 indoor unit which provides general telecommunications interfaces and mounts to a standard 19" rack.
