Wireless FAQ

1. • Is there a table with supported tuning ranges or channels (ETSI) with frequencies (TxLow & TxHigh)?We need to know which frequency channels are supported by TERARANGE equipment because of the licensing here.
Using Radio Wizard you can obtain precise Tx and Rx central frequency range in the chosen bandwidth. By the way the working frequencies of TERARANGE devices are :
Licensed : 6 - 7 - 8 - 12 - 13 - 18 - 24 - 36 Ghz
Free license : 2.4 - 5.8 Ghz
You have to consider that you are allowed to use free license radios based on your country/region  regulatory domain and obey the radio radiation power. for more information please visit your country regulatory bureau website.

2. • What are the ways of products delivery, incoterms (regarding TERARANGE)?
The way of product delivery is decided with due consideration of each individual client and order details. According to the price list, we offer standard UPS Budapest delivery.

3. • Is it possible to arrange SOR order?
Yes, new products (one piece per order) can be sold to the client as part of Sales or Return condition, so that the client can evaluate functionality and suitability of products before making bigger orders.

4. • Does TERARANGE sell its products by installments?
Due to some specific configurations on TERARANGE devices, TERARANGE technical staff will do the installment process.

5. • Is it possible to arrange delivery of TERARANGE products to a specified destination?
TERARANGE can arrange delivery of its products to locations covered by the services of our partner transportation companies. Delivery conditions can be defined when a concrete delivery order is received.

6. • Is it possible to arrange TERARANGE presentations locally?
Yes, it is possible to hold presentations upon request. Please contact our sales department.

7. • Do TERARANGE radio links have limitations regarding height over sea level?
The only limitation is operation temperature, which must not exceed -30°C for Full Outdoor Unit / Outdoor Unit (ODU/FODU) and -5°C for Indoor Unit (IDU).

8. • How is it possible to upgrade Skyfiber link capacity?
Capacity of equipment operating at full capacity cannot be increased but anyway the link capacity is not based on license and so you can have as much throughput as your link can has.

9. • What is the difference between FODU and ODU?
Full Outdoor Unit (FODU) comprises management controller, modem, multiplexer and radio in one unit, whereas Outdoor Unit (ODU) comprises only radio part and requires Indoor Unit (IDU) for operation.

10. • Where should lightning arrestors be installed? Are lightning arrestors obligatory?
Lightning arrestors are highly recommended for system stability.
The following lightning arrestors are required for all of the TERARANGE products:
FODUs : power/Ethernet/E1 at user equipment side;
IDU/ODU : on coaxial IDU-ODU cable at ODU and IDU sides;

11. • Is TERARANGE equipment compatible with the equipment from third-party vendors?
In a single link only TERARANGE equipment is interoperable, while outgoing interfaces are compatible with any equipment with appropriate interface support and on SF-5800, SF-2400 you can use any antenna type base on your needs and conditions.

12. • What accessories are required for the link apart from antenna and ODU-IDU/FODU?
Accessories may vary depending on a link configuration planned. Common accessories for any configuration are mounting tools, lightning arrestors, power supplies, appropriate interface cables and connectors.
For any further details please contact sales department

13. • What is the maximum link distance with TERARANGE equipment?
Normally links are installed and used on distances over 10-70 km, though every individual case requires discrete calculation because there are plenty of aspects to take into consideration (required capacity, fade margin, rain/multipath availability, available bandwidth, topography of the region, annual temperature, rain zone, height over sea level, antenna size, etc.). Under favorable conditions distance may be increased up to 150 km, but under unfavorable conditions distance may decrease to 10 km. Please refer to case study examples to assess real world practice.

14. • What is the maximum link capacity with TERARANGE equipment?
SF-MW Series FIDU - 800Mbps ( mixed payload of Ethernet, STM-1, E1 )
SF-5800 Series FODU - 300Mbps ( with protection switching )
SF-3600 Series FODU - 106Mbps ( 100Eth+4E1 )
SF-2400 Series FODU - 200Mbps ( 100Eth )

15. • Is TERARANGE equipment compatible with Network Management Systems from third-party vendors?
No, TERARANGE equipment is compatible only with TERARANGE Network Management System (TRNMS).

16. • Why the price on the equipment for licensed frequency bands is higher than on the equipment for unlicensed frequency bands?
Equipment for unlicensed frequency bands is being broadly produced as consumer goods. Equipment for licensed frequency bands is specific and is not being designed for mass production, which has impact on its costs.

17. • What is the difference between unlicensed and licensed frequency bands?
In most cases unlicensed bands are industrial, scientific and medical (ISM) radio bands which originally were reserved for non-communication purposes. Hence, unlicensed operation needs to be tolerant of interference from other devices and limit output power according to local radio band regulations. Licensed operation guarantees interference-free operation and transmission with necessary output power, which eventually results in much longer link distances.
