4G – what’s all the hype about?

4G is the fourth generation of cellular wireless technology standards and the term is normally used when referring to Long Term Evolution Advanced (4G LTE) and WiMAX, with both technologies offering high speed wireless data rates.

4G networks deliver higher bit rates and better audio quality for remotes over wireless data networks when compared with 3G. 4G LTE networks are the natural progression from WCDMA/UMTS 3G networks and have been rolled out in many countries across the globe.

Tieline's 4G module solutions are designed to connect to 4G networks and automatically fail over to 3G/HSPA+ networks when 4G coverage is unavailable. Check with your local Telco to ensure this functionality is available.

The Tieline 4G LTE (7304) module accepts a SIM card and is commonly used in most of Europe, Australasia and some other countries; please visit the 4G LTE page for more details.

Note: Tieline wireless modules for the Americas are currently unavailable. To connect over 4G LTE networks in these regions we recommend using a Cradlepoint wireless router.

IMPORTANT: From April 2015 Tieline no longer sells the USB G3 module.
Tieline also no longer supports the use of the following modems in USB G3 modules:
  • Pantech® 4G LTE USB Modem UML290 (available from Verizon Wireless™)
  • Verizon Wireless™ 4G LTE USB Modem 551L (available from Verizon Wireless™)
  • Telstra™ USB 4G Modem 320U (available from Telstra™ retailers in Australia)
This is due to customers encountering connection problems when using these modems.

What’s better, 3G or 4G?

3G networks maintain widespread coverage in nearly all countries and regions, so don’t throw away your 3G gear just yet!

3G wireless networks are adequate for broadcasting wireless IP audio using algorithms like LC-AAC, HE-AAC, Tieline Music and Opus, however many regions now experience congestion due to large numbers of network subscribers sharing limited available bandwidth.

4G offers significantly higher bit rates and therefore more reliable connectivity. Be careful to not connect your codecs at bit rates which don’t offer any additional audio quality and just eat up your data allowance much faster!
