In late 1997 BSWD swung back to the horizontal market with a vengeance staking the future of the business on two-way paging. What do these vertical horizontal buzzwords mean To most people a vertical is application specific perhaps parts order entry from a mobile device transmitted upward to the same company s host computer for processing.

The applications are not generic and do not transfer well from say high-technology medical computer service to truck repair service or to public safety or field sales for that
