Understanding the impact of mobile broadband capacity limitations

Written by GoS on . Posted in Blog

Current limitations with mobile broadband capacity effectively constrain application performance – and hence, user experience.

From the user perspective, there are two aspects of bandwidth consumption that are important:

  • Upstream traffic; that generated at subscriber devices; and
  • Downstream traffic; that delivered to client devices.

Quite simply, consumers expect bandwidth capacity for downstream traffic to be sufficient to power the applications they want at an appropriate performance level. Traditionally, MNOs have focused on achieving sufficient downstream traffic performance. However, user-generated traffic can be equally important when addressing capacity concerns, but it is often overlooked by MNOs. In a typical network, greater capacity is available in the downstream direction with the result that upstream bandwidth is more easily saturated.

Increasingly, mobile users are generating greater volumes of traffic, all of which needs to be delivered by the network. This is associated with, among other things, the rise of user-generated content, increased use of Voice over IP (VoIP) clients for communication, and “Peer to Peer” (P2P) traffic. However, this presents an additional problem for MNOs: some of these applications create revenue, while others simply burden the network. In addition, the combination of different traffic sources may cause problems for certain applications. For example, heavy P2P traffic (which does not generate revenue) may limit the effective transmission of revenue-generating services, such as VoIP, or cause disruptions to other real-time services.

The continued rise in downstream and upstream traffic leads to congestion in the network that inhibits the performance of applications in both directions. It’s simply not tenable to continue costly investments in bandwidth. Alternative solutions that use bandwidth more efficiency must be pursued.

Reducing the strain of Video Traffic in Mobile Networks

Streaming video is an application that is experiencing strong growth from mobile users. Deploying GoS in Mobile Dongles can reduce peak load from video traffic by 50%.

Estimates by Cisco and others suggest that half of all traffic in mobile networks is derived from video delivered to mobile broadband clients. That’s an awful lot of traffic, so it’s no wonder it can cause significant downstream congestion when downloading takes place at the maximum possible bandwidth.

Calculations suggest that applying GoS to streaming video traffic could reduce the overall peak load by nearly 50%, which is equivalent to 9.5 months traffic growth at current rates, estimated at 108% CAGR. That’s essentially delaying the CAPEX investment in new infrastructure for three quarters.

Additional calculations based on streaming rates indicate that use of GoS can result in a 20% reduction in the amount of video data consumed.

Mobile Operators can’t keep up with demands

Written by GoS on . Posted in News

Mobile operators are struggling to meet capacity demands, despite continued heavy CAPEX and OPEX investment.

Data from Cisco suggests a CAGR of 108% for mobile data traffic between 2009 and 2014 (Cisco, 2010). MNOs simply cannot upgrade capacity fast enough!

Insufficient bandwidth provision leads to poor network performance which has a negative effect on subscriber experience which leads to dissatisfaction with the network provider which ineviably leads to customer churn.

Is the answer to allocate/ create more bandwidth? Can operators really afford to do that?

The challenge for MNOs is to manage CAPEX and OPEX investments to ensure return on investment is maximised, and to deliver the levels of enhanced performance that are now being demanded by users.
