In August 2013, LiveU officially launched its full range of products based on wireless cellular communication such as 3G and 4G. This includes the well-known LU60 (which has now gradually been replaced by the LU70) and LU40, as well as mobile terminals, enhanced antennas, and solutions for other applications.

In today's world, where 4G/5G live broadcasting equipment is increasingly valued, the 4G news live broadcasting system plays a significant role in more and more fields. However, many potential customers may have a question before purchasing 4G news live broadcasting equipment: Since 4G news live broadcasting devices are wireless and highly mobile, how does the 4G backpack address the power supply issue while ensuring freedom of movement? This is a concern for both current and future users of 4G news live broadcasting equipment.

• At this year's NAB, Israeli company LiveU launched its second-generation fully integrated product line within its compact cellular backpack transmission solution family for live television and online reporting.
• The new LiveU HD series products come with a wealth of features, such as 1080i HD video resolution, and they deliver outstanding performance even with an ultra-low delay of 1 second.

LiveU, a pioneer in portable wireless video backpack solutions, will showcase its enhanced LU60 video uplink series at the 2011 NAB Show in Las Vegas (Booth SU8808). This series achieves sub-second latency and outstanding resilience with multiple bonded 4G/3G connections. With ultra-low latency, LiveU's powerful broadcast-quality video uplink provides customers with a cost-effective alternative to satellite solutions for live two-way interviews on location.

The concept of this solution is to utilize the existing ubiquitous 4G/5G mobile networks, WiFi hotspots, and the internet for live audio and video transmission during on-site reporting. Thanks to the excellent coverage of 4G/5G networks, reporters can roam freely indoors and outdoors without being restricted by cables or line-of-sight between two points, and they are also unaffected by weather factors such as rain fade or snow fade.

The LU700 is a hybrid video system uplink solution for vehicles and fixed locations launched by LiveU.

LiveU's LU² is the world's first modular uplink solution that optimizes the use of existing cellular networks; it can provide additional bandwidth flexibility by combining two LiveU units. With the LU² concept, operators can easily increase the number of connections, pulling up
uplink bandwidth when needed by connecting an additional LiveU unit via a standard Ethernet cable.
