There are several factors that govern the selection of coaxial cable for your Machine to Machine (M2M) application: the location of cable runs, either indoor or outdoor, inside or outside an enclosure, maximum bending and the maximum length of the individual cable runs. Today I talk about the bending.<\/p>\n
For coaxial cables inside your enclosure, the bending can be critical. If you bend the coaxial cable to hard, then the Voltage Stand Ratio (VSWR) will rise. The VSWR is the parameter that tells you how many of the transmitted radio energy will run back to the generator. The generator will be your GSM module\u00c2\u00a0 (or any other wireless module). The GSM module will generate a radio wave that will be forwarded to your GSM antenna and from there to GSM base station. Backward the GSM antenna is the generator. The antenna should catch as most as possible radio energy and feed it to the coaxial cable. You can use best GSM module with highest sensitivity and best GSM antenna with optimum antenna efficiency \u00e2\u20ac\u201c Worst case a wrong bended coaxial cable will damage your expected result of your wireless M2M application. Please take care and read the specification of the selected coaxial cable. Please also take care, that you never bend the coaxial to hard during your test of your M2M application. You have no chance to see from outside, that the coaxial cable is already broken and you just will wonder why the performance of your wireless M2M application is so poor.<\/p>\n
Do you still have further questions? Are you not sure which wireless module to select? Are you not sure which antenna will give you best performance? Are you not sure which coaxial cable you have to select?<\/p>\n
