Nokia in MicroWave Radios

• Business operations started in 1960´s

• Strong Global Position achieved via GSM challenger market growth in 1990´s

• Nokia is • No. 2 in cellular transmission • Among 3 top players in global PDH-radio market

• R&D and manufacturing site in Karaportti Espoo





Key trends in mobile network transmission • Capacity need per basestation is increasing

• … but timing is difficult to predict • Networks should have inbuilt flexibility to meet

"unknown“ capacity needs

32 TCM modulation enables doubling the spectrum efficiency

• narrow spectrum - 16x2Mbit/s capacity into 14 MHz frequency channel – currently 28MHz

• capacities 8 x2Mbit/s and 16x2Mbit/s supported

Support of all existing features • All FlexiHopper features • Same antennas, alignment units, mechanics and

indoor units can be used

See the roadmap for availability





Nokia FlexiHopper Plus See the roadmap for availability

Main benefits

• Possibility to double the current transmission capacity within the existing frequency channel

• Savings in operational costs because of lower frequency bandwidth licence fees

• Better availability of free channels, 14 MHz vs

28 MHz

• Selectable modulation and capacity enable optimal and flexible usage of frequency bands

• Built on reliable and proven FlexiHopper platform with backward compatibility

Expansion from 4E1 to 16E1 : traditional radio

-Site visit is a must, expansion not possible remotely from NMS.

- Downtime for expansion can be significant

- More site space may be required – needs prior technical site surveys
