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 compared to 3G. 4G LTE networks are the natural progression from WCDMA/UMTS 3G networks and have been rolled out in many countries across the globe.

WiMAX Metropolitan Area Networks (MANs) using Wi-Fi are also being rolled out across the globe and offer an alternative to LTE technology for wireless IP broadcasting.

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.

Tieline 4G Wireless Module Options

Tieline has you covered with a range of 4G module options to allow Commander G3 and i-Mix G3 codecs to connect over 4G LTE wireless networks.

Two versions of Tieline 4G LTE modules are available to support different wireless networks globally and both modules accept full sized SIM cards. These modules are:

  1. 4G/3G (7304)
  2. 4G/3G (7354)
To find out which one of these modules will work in your region please visit the 4G LTE page.
If you want to connect using Verizon 4G networks in the US you can use the 4G USB module (see text which follows).

The 4G USB module allows your codec to broadcast live over available 4G networks using a third party 4G USB modem (additional purchase). Please check with your Telco to verify your area has coverage.
In the United States the 4G USB module works over the Verizon Wireless™ 4G LTE network using the following modems and supports 4G LTE (700MHz), as per modem specifications:
  • Pantech® 4G LTE USB Modem UML290 (available from Verizon Wireless™)

  • Verizon Wireless™ 4G LTE USB Modem 551L (available from Verizon Wireless™)

In Australia the 4G Wireless Module works over the Telstra™ network using the following modem:

  • Telstra™ USB 4G Modem 320U (available from Telstra™ retailers)

For all other countries please contact Tieline to find out which modems are suitable.

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 Tieline MusicPLUS, 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.
