The president of Rysavy Research is Peter Rysavy:
Since 1993, Peter has worked as a consultant with numerous clients on projects involving personal and mobile communications. Clients include cellular carriers, communications software companies, network hardware companies, automotive electronics companies, research organizations and universities. He also teaches seminars, leads a standards efforts, and writes articles on wireless communications.
Peter graduated with BSEE and MSEE degrees from Stanford University in 1979, where he was involved in several university/industry collaborations involving statistical and digital signal processing. Joining Fluke Corporation in 1979, he designed communications hardware and software for data acquisition products. From 1981 to 1983 he designed Ethernet networking hardware at Time Office Computers in Australia. He rejoined Fluke, and until 1988 managed the development of a family of communications-oriented touch terminals.
From 1988 to 1993, Peter was VP of Engineering and Technology at Traveling Software (makers of LapLink). In his last major project, he specified and evaluated radio technology for LapLink Wireless. He also managed the development of LapLink and connectivity solutions for a broad variety of mobile platforms.
In December 2000, Peter had this to say about about GSM GPRS in a very good Network Magazine article called "Emerging Technology: Clear Signals for General Packet Radio Service" and he stated:
If you think GPRS will become obsolete once third-generation cellular rolls out, think again. Data services for Wideband Code Division Multiple Access (CDMA, the 3G version of GPRS) use an evolved set of GPRS protocols and infrastructure. ... given GPRS's worldwide dominance, GPRS will be this decade's key wireless data technology.
<snip>
As for speed, you'll see figures quoted all over the map, because operators can flexibly deploy GPRS. Though GPRS' maximum theoretical rate is just over 160Kbits/sec, operators will initially offer speeds in the 26Kbit/sec to 52Kbit/sec range. Although not blazing fast, this speed compares to the speeds road warriors are used to, and works for many applications. QoS will enable applications to specify items such as throughput, latency, and reliability, but don't expect much emphasis on QoS in initial rollouts. Rather, think of QoS as a key feature for enabling future wireless multimedia applications, such as voice and video.
<snip>
So, will all GPRS applications use WAP? Absolutely not. Users can consider GPRS for any IP-based application, so long as the application isn't too bandwidth-hungry. Nevertheless, GPRS carriers are looking to GPRS as a key enabling technology for WAP because GPRS offers the perfect always-on, always-connected transport for WAP. Carriers are interested in WAP for another reason. GPRS could quickly become a victim of its own success if too many people use it for large downloads. Since users contend for a limited number of GPRS radio channels, throughput will go down with an increasing number of active users. WAP addresses this issue by a text orientation and small screens, thus minimizing the network's load. Carriers are likely to push WAP over GPRS vs. general-purpose networking.
