Will Mobile Operators Face a Capacity Crunch Soon?By Richard KinderVP of Technology and New Business for Europe Red Bend Software Mobile data has finally arrived. After years of hype, the volume of data on mobile networks is reported to have surpassed that of voice traffic. Whilst the majority of this traffic is driven by people with mobile broadband subscriptions, undoubtedly the new breed of data-intensive mobile devices contributes significantly to this rapid growth. This bandwidth consumption is stressing the edge of the network and backhaul, resulting in a potential field day for providers of optical and microwave infrastructure. I could successfully argue that the capacity crunch is already upon us. A frequently cited answer to congestion problems is to off-load mobile data from the mobile core network. Various techniques may be deployed to achieve this, such as WiFi or Femtocell offload. For the best results, both approaches rely on mobile devices being aware of their network context and acting accordingly. Unfortunately, the majority of handset software platforms have yet to acquire the necessary smarts to make best use of these whilst staying within the strict energy budgets imposed by today’s battery technologies. We should not forget that bandwidth usage is only one metric by which to measure mobile network capacity. As has been highlighted in numerous articles, blogs and elsewhere during and since Mobile World Congress 2010, today’s mobile devices also impose a greater signalling burden on the mobile network. Whilst I am yet to receive a clear explanation of exactly what signalling traffic is generated, one can hypothesise that the desire to preserve battery life results in these devices frequently establishing and tearing down PDP contexts, which in turn creates signalling traffic within the operator’s infrastructure. So what can the industry do about this? 4G standards such as LTE and WiMAX eventually will allow for future growth in mobile data usage – the key word being future! Prior to the halcyon days and unlimited bandwidth of 4G, network operators are committing significant amounts of money to enhancing their existing 3G infrastructure. As developers of device software, we too have a role to play, for example:
We cannot rely solely on network operators’ investments in infrastructure to address the capacity crunch. We have a responsibility to use what they provide as efficiently as possible. Services and platforms that can help operators manage their capacity concerns just may be more appealing to them. To misquote Scott McNealy (he of “the-network-is-the-computer fame”), one day datatone will be as important as dialtone. That day is here.

Device Management Is Essential for Managing a Range of Wirelessly Connected DevicesBy Yoram BerholtzSenior Product Manager, Red Bend Software The demand for constant connectivity is at an all-time high. Consumers want mobile phones that work wherever they are and whenever they need them–at home, in the office, on the road and across geographies. These demands create a big challenge for mobile operators, which want to manage all the devices in their network in a unified way, regardless of the type of device or software platform. As a result, operators globally are harnessing the Open Mobile Alliance Device Management (OMA DM) standard to meet the demands of this increasingly diverse environment and ensure a consistent and satisfying mobile user experience. Ovum recently reported that 36% of global handset shipments support OMA DM. Device management has become especially crucial to open platforms like Android, Brew Mobile Platform, Symbian and LiMo, as these platforms are feature-rich and geared to support rapidly evolving applications. Typical capabilities of DM include subscriber provisioning, connectivity configuration, firmware updating, diagnostics and monitoring, and software installation—all of which can be performed over the air (OTA). These capabilities result in lower support and maintenance costs for OEMs and operators while providing increased consumer satisfaction with their mobile device and service. With DM, operators and handset manufacturers can activate new subscribers on the network, configure parameters including preferred roaming lists, retrieve data such as billing and inventory as well as conduct “lock and wipe”—remotely shutting down the mobile phone and deleting its memory in case it’s lost or stolen. It’s not just mobile phones that require DM. Recent WiMAX deployments in the United States (Clearwire) and Japan (UQ Communications) adopted OMA DM as the main provisioning and management standard. These service providers are actively equipping their mobile devices, such as WiMAX modems and chipsets, with DM client software. By embracing the OMA DM standards, companies can ensure out-of-the-box interoperability in all the major WiMAX networks. As important as OMA DM is to the current phase of WiMAX deployment, it will be even more important as these networks evolve by being able to deliver more advanced applications and services to WiMAX consumers in the future. The prospects for WiMAX are merely up to the imaginations of the operators and their ability to offer attractive services, regardless of the device. The bandwidth capabilities anticipated in WiMAX will likely bring unprecedented access to video, movies and more, driving additional revenue streams to operators, manufacturers and ISVs as new services and applications become available. Machine-to-machine (M2M) is another wireless segment that has adopted OMA DM for two reasons: 1) the nomadic nature of some M2M segments (e.g., automotive and telematics) force the module to engage with several networks and even roam to other countries; thus, the module must be able to work in a multi-server environment, and (2) the cost of adopting standards-based DM is much less expensive than a proprietary environment because the integration with devices and the certification with networks can be quicker. With the inherent functionality that exists in OMA DM, such as provisioning, managing security and the ability to work globally, operators can benefit from lower cost of ownership by using their already deployed OMA DM infrastructure and utilizing it for M2M. Red Bend Software’s vDirect Mobile™ is the leading independent DM client. vDirect Mobile has been adopted by more than 30 manufacturers of wirelessly connected devices in the mobile, WiMAX and M2M markets, and is interoperable with any DM server supporting OMA DM standards. It also uniquely supports the WiMAX Management Object (MO) for managing mobile WiMAX devices according to specifications from the WiMAX Forum. During the next five years, mobile devices will become more advanced and have many integrated features and connectivity standards. Device management is essential for enabling manufacturers and operators to manage such a diverse installed base in a unified way.
