2. Wimax, Wireless Multimedia
WiMAX is quickly establishing itself as the access medium of choice for ILECs and Mobile Operators for their next generation mobile and fixed IP delivery needs.
The application space supporting the burgeoning WiMAX eco-system is a testament to this – one need only visit the Member’s page of the WiMAX forum and see companies such as Disney, Microsoft, Cisco and a veritable Who’s Who among the international Operator community. WiMAX supported applications are truly only limited by a viable business case, spectrum, and opportunity. True 4G services will include IP-TV, Mobile Data, Security Surveillance, Broadband Internet Access, fixed and mobile Video delivery, and VoIP, to name but a few. The robust capacity, unsurpassed throughput and spectral efficiency, and economics afford profitable infrastructures for these applications. We outline here just a few applications which our early customers are delivering to satisfied end-users on three continents. Broadly speaking, these applications fall under the rubric of “Quadruple Play” services of voice, data, video and mobility.
WiMAX finally delivers the reliable and cost-efficient bandwidth which competitive providers of video services have been asking for. On a per sector basis, WiMAX with beamforming gain, which only PureWave Networks supports, will yield operators over 40mbs of “good-put” on a 5MHz channel – more than adequate for profitable IP-TV and similar offerings. Add to this the exciting developments in FemtoCells and Home Base Stations and we begin to see compelling viability in this application space.
3. Broadband, Voip, Mobility
VoIP and Broadband data for residential and small business users are two key elements of any Service Provider’s WiMAX Business Case. Central to the success of any wireless business plan are optimizing the “Three C’s” – coverage, capacity and cost. PureWave Networks WiMAX solution outscores the competition by any analysis of these metrics.
Beamforming and coherent energy null steering directly add to the link budget of our wireless access solution. Our many customers are finding that the PureWave Networks solution delivers increased coverage (often 2-3 times) with fewer base stations – this directly optimizes the coverage element of the business case.
A Service Provider needs to be able to satisfy the needs of a bandwidth-hungry customer population often with modest licensed spectrum allocations. PureWave Networks WiMAX solution delivery 6X the capacity of competitive systems through perfect frequency re-use of one across all cells and through beamforming gain of multiple antennas. Our customers are demonstrating that the spectral efficiency of a PureWave Networks system is 15+ bits/second/hertz – orders of magnitude beyond non advanced antenna system solutions.
Cost is a critical consideration obviously, and for many years has been the fundamental weakness of multiple antenna solutions given the additional hardware required and the multiple DSP’s required given the inherently computationally intense nature of smart antennas arrays. PureWave Networks has understood this and made smart choices at the design and software level to ensure that we can profitably sell our advanced Base Station infrastructure at a price suited to WiMAX business cases. Our low cost internet base station is 1/3 the price of the competition while delivering on capacity and coverage.
Voice remains the principal application for WiMAX and indeed all access technologies. As they say, voice may not be glamorous, but it still “pays the bills” for most Service Providers. It is estimated that the worldwide Service Provider community adds in excess of 60 million basic voice users annually – and VoIP is beginning to take the lion’s share of these new customers for all obvious reasons associated with the compelling economics of the Internet and IP Switching fabric. One need only look to the phenomenal success of Skype as proof of the disruptive nature of VoIP. The WiMAX 802.16e Standard has been engineered with this is in mind. There are carrier class Quality of Service (QoS) hooks in the standard which, for the first time over wireless IP voice, ensure MOSS scores of 4 and wire-line equivalency in terms of latency, jitter and voice quality. PureWave Networks PureMax solution incorporates these QoS features and our customers are today delivery wire-line equivalent voice services to their customers as a key part of the business offering
Broadband Wireless Access to fixed users has been around for many years and adequately serves a DSL-replacement market with proprietary solutions. As this industry has coalesced around the WiMAX standard, more and more Service Providers have become increasingly comfortable acquiring spectrum and investing in WiMAX as an access technology of choice. With the addition of mobility in the 802.16e-2005 variant of the Standard, an avalanche of interest has arisen around this technology as the true successor to 3G.
PureWave Networks WiMAX solution today supports ranging, doppler and hand-off between base stations and base station sectors – thereby supporting operator business cases which require some portability and nomadicity. True vehicular mobility will be supported, as a central element of the “E” standard, by the end of the year. This coincides with the anticipated launch date by Intel Corporation of WiMAX E chipsets in laptop computing devices for the mass market. PureWave Networks will deliver best-in-breed support for mobile data access – whether for VoIP or Broadband Data users – by leveraging our advanced beamforming and null steering technologies.
