Project Description

A Project Manager from COMPUCENTER got in contact with Netkrom Representatives with the need of setting up a WISP system in the city of Abidjan.

In that sense the initial idea was to setup strong and robust Base Stations that could broadcast to mobile users and residential subscribers simultaneously so they could surf the Internet or make calls through Wi-Fi phones.

The project also included enterprise customers who required 100% secured and reliable connections 24 hours a day with the maximum affordable bandwidth.

The base station ISP-BS500 SERIES possesses a robust and advanced design in hardware and software which makes it support both Wi-Fi and WiMAX technologies.

In the case of Enterprise users we considered the 5GHz frequency and the use of the ISP-BS500AH with 4 wide band sector panel antennas. This equipment included 4 radio modules with each one outputting 600mW covering the bands from 4.9 to 6.1GHz, as well as the advanced management software “Netkrom NMS” which provides High control management over the entire Network.

The Base Station will be used to give Internet access to enterprise customers who will use the ISP-CPE500AHP to receive the signal from the Base Station at a distance of 12km. This Base Station will be able to communicate with other relay points which will also give a Wi-Fi connection to customers in 2.4GHz. The wireless relay points are able to redistribute the same flow to end customers as a switch has a feature of providing the same bandwidth to each customer with the relay.

Each relay point is made of the ISP-BS500AGUHP Multiband Base station which is an outdoor radio Access Point with four High Power wireless ports at 2.3-2-7/4.9/5GHz, 802.11a/b/g standard-compliant, future WiMax and 802.11n.

This Base Station with a 1 Watt of maximum output power would broadcast the signal to mobile and residential subscribers in the 2.4GHz band making Internet browsing and IP calls possible.

Three sector panel antennas each one with 16dBi and 120 degrees would provide full wide area coverage, the backhaul port in 5GHz with 400mW of power and a parabolic dish antenna would ensure the bandwidth to support the large number of subscribers.






Benefits:

• Scalable Base Stations that are upgradeable to WiMax. This will increase the bandwidth capacity and the number of subscribers.

• Easy integration between several Base stations through rely points.

• Minimum latency in the VoIP solution thanks to the prioritization over the voice - WMM (Wireless Multimedia).

• Easy equipment installation, mainly with the Wireless Base Station ISP-BS500, which includes three RF ports for broadcast and one RF port for Backhaul.
