Abstract: A toe guard for use on a wheel assembly may include a first and second sidewall, each sidewall including an opening configured to engage with an axle of the wheel assembly. The first and second sidewalls may each further include one or more notches. The toe guard may further include a first locking pin configured to engage with at least one of the notches of the first and second sidewalls. Additionally, the toe guard may include one or more support plates connecting the first and second sidewalls, and a front plate configured to engage with at least one of the support plates or connect with at least one of the sidewalls.

Abstract: Architecture that efficiently adds additional carrier(s) (e.g., UMTS) to a wireless operator's network which allows the additional carrier(s) network to co-exist with other technologies by sharing the spectrum in geographically adjacent sites. When employing UMTS, the UMTS is CDMA-based such that all users utilize the same frequency 5 MHz band. With this innovation, additional carriers (e.g., a 2nd 5 MHz UMTS carrier) can be added when capacity is needed on a site-by-site basis without clearing an additional 5 MHz of spectrum.
