4G – what’s all the hype about?

4G LTE modem (sold separately)
4G is the fourth generation of cellular wireless technology standards and the term is normally used when referring to WiMAX and Long Term Evolution Advanced (4G LTE), with both technologies offering wireless data rates of up to 1 Gbit/s.
Connecting to 4G networks can give your remote broadcast higher bit rates and better audio quality. 4G LTE networks are the natural progression from WCDMA/UMTS 3G networks and are being rolled out in many countries. 4G LTE will start to be rolled out more extensively throughout the next few years in order to achieve nationwide US coverage by 2013.
Metropolitan Area Networks (MANs) using Wi-Fi, and commonly reffered to as WiMAX, are also being rolled out across the globe and offer an alternative to LTE technology for wireless IP broadcasting.

What’s better, 3G or 4G?
Currently, 3G UMTS/HSDPA/HSUPA has much more widespread coverage in nearly all countries and regions, so don’t throw away your 3G gear just yet!
3G wireless networks are quite adequate in terms of available data bandwidth for sending wireless IP audio using algorithms like LC-AAC, HE-AAC, Tieline Music and Tieline MusicPLUS, so your broadcast audio quality certainly won’t suffer using wireless 3G.
Increasingly, as 4G is rolled out you may find it useful to have a 4G data service in your broadcast kitbag to take advantage of 4G wireless coverage when there are holes in 3G wireless coverage. Remember though, because 4G offers significantly higher bit rates, you might be tempted to connect your codecs at bit rates which don’t offer any additional audio quality and just eat up your data allowance much faster.
One big advantage of 4G is the ability to hang multiple services off a single connection. The additional bandwidth available may allow you to connect a PC, a codec and IP based remote control equipment reliably over new generation wireless networks. Keep an eye on your data costs though!
