Frequency Bands: Sonera Finland, now Telia Finland, uses 2 GSM bands, 2 UMTS bands, and 3 LTE bands.
Name Change: The company changed its name from Sonera to Telia on March 23, 2017, as part of a broader rebranding effort by Telia Company.
Ownership: Telia Finland is owned by Telia Company, a Swedish multinational telecommunications company. The Swedish state holds a 37% stake in Telia Company, while the Finnish state had a 3% stake until it divested in 2018.
Market Position: Telia Finland is the second-largest mobile operator in Finland, accounting for 34% of Finnish mobile subscriptions and 30% of broadband connections as of 2015.
Services: Telia Finland offers a range of services, including mobile internet, which was first launched via Wireless Application Protocol (WAP) in 1999, making it the world's first mobile operator to do so.
Network Deployment: In 2014, Telia Finland and DNA Oyj jointly deployed a shared 4G LTE network using the 800 MHz band in remote Northern and Eastern Finland under the Suomen Yhteisverkko Oy joint venture. Telia Finland owns 51% of this joint venture.
These details provide a comprehensive overview of the mobile network operations of what was formerly known as Sonera Finland.
Frequency Bands
GSM
| Name | Interface | Description |
|---|---|---|
| 900 MHz (E-GSM) | GSM | Sonera Finland uses the GSM 900 MHz (E-GSM) frequency band. The deployment of this frequency band is not specified. |
| 1800 MHz (DCS) | GSM | Sonera Finland uses the GSM 1800 MHz (DCS) frequency band. This band is used for the downlink (base to mobile) and uplink (mobile to base) communications. The specific frequency ranges for this band are 1800 MHz for the downlink and 1800 MHz for the uplink. |
Supported GSM Protocols
| Name | Generation |
|---|---|
| EDGE | 2.5G |
UMTS
| Name | Interface | Description |
|---|---|---|
| B1 (2100 MHz) | UMTS | Sonera Finland uses the UMTS B1 (2100 MHz) frequency band. This band is widely used for 3G services and is supported by various networks. The deployment of UMTS B1 (2100 MHz) in Sonera Finland began in 2001. |
| B8 (900 MHz GSM) | UMTS | Sonera Finland uses the UMTS B8 (900 MHz GSM) frequency band. This band is used for UMTS services. |
Supported UMTS Protocols
| Name | Generation |
|---|---|
| UMTS | 3G |
| HSPA+ | 3.5G (4G speed) |
LTE
| Name | Interface | Description |
|---|---|---|
| B3 (1800 MHz +) | LTE | Sonera Finland uses LTE Band 3 (1800 MHz +) for its LTE network. This band is one of the most widely used frequency bands for LTE deployments globally, facilitating international roaming for mobile broadband services. It supports both FDD (Frequency Division Duplex) and TDD (Time Division Duplex) configurations, offering a balance between network coverage and data capacity, making it suitable for dense urban areas. |
| B7 (2600 MHz) | LTE | Sonera Finland uses LTE band B7 (2600 MHz). |
| B20 (800 MHz DD) | LTE | Sonera Finland uses the LTE B20 (800 MHz DD) frequency band. This band is known for its wide area coverage and deep penetration, making it suitable for regional and rural environments, as well as in-building coverage. It is also popular for IoT applications like eMTC (LTE Cat M1) and NB-IoT (LTE Cat NB1) due to its wide coverage characteristics. The 800 MHz band does not easily support Massive MIMO and beamforming technologies due to its large wavelength. It can be used as a single band or as part of a multi-band network, and it supports carrier aggregation with other bands to enhance bandwidth and performance. |
