Kahlua et all ***MUST READ***. T/A is bullshit, read about the company. multichannel.com Vendors reported that Sprint and MCI are already shopping for solutions in the fixed-wireless arena at the MMDS 2.5-gigahertz spectrum tier that will allow them to integrate what was once a one-way wireless cable platform into the two-way broadband mesh of the future. This includes a move from the single-transmitter-per-market design to cellularization, in which several transmitters would reuse bandwidth. "We will break the serving areas up into smaller cell sizes," Finch said, acknowledging that this would add substantial costs to the approximately $1 billion that MCI is spending to acquire the wireless cable properties of CAI Wireless Systems Inc. and Prime One. Sprint chief technology officer Marty Kaplan, in an interview, also made it clear that cellularization is a likely step in his company's efforts to maximize the use of the relatively small amount of bandwidth -- about 200 megahertz -- that comes with MMDS, versus the 1.15 GHz used by local multipoint distribution service. "I doubt that we'll put just one stick up in an area," Kaplan said, adding that Sprint is also looking at the use of "intelligent waveguide" technology as a means of expanding bandwidth efficiency. Vendors are responding to the need to maximize the efficiency of MMDS spectrum, and several have introduced sectorized transmitter systems. Sectorization divides the serving area into 90-degree or smaller slices, thereby greatly increasing the total available bandwidth from a given transmitter. Hiram
