I will be implementing a Point to Multipoint wireless network with nine CPE510s. Need somebody to walk me through the configurations of the TP Link Pharos for optimum performance.
Initially the APs will be setup to link IP Cameras to the NVR. Later,internet sharing, ] file sharing and VoIP (If Possible). The APs will be 50-80 metres apart. The CPE510 offers three modes of wireless 802.11a, 802.11n, 802.11a/n for configuration. Which mode will allow all devices to connect as most laptops and mobile phones are 2.4Ghz.

Thanks in advance

As you wrote, the CPE510 supports 802.11a/n (5 GHz standards), not 802.11b/g/n (2.4 Ghz standards). To support 2.4 GHz you should consider use of a CPE210. For a PtMP setup with as much as 9 CPEs you should be aware that their antenna beamwidth is 65° (CPE210) resp. 45° (CPE510). Depending where the client APs are located, a WBS210/510 with a sector antenna such as the TL-ANT2415MS resp. TL-ANT5819MS would probably the better choice for the serving AP (both antennas have 120° beamwidth).

What also needs to be considered before buying the devices is the distance of the CPEs to each other. Having 9 devices in an area of 50-80 meters distance from the central AP will most likely cause interferences in the 2.4 GHz frequency band. Since in this band you have only 3 non-overlapping channels in 802.11b mode (4 non-overlapping channels in 802.11g/n mode and 20MHz channel width), a setup of 9 devices will require careful configuration to minimize such interferences, which could led to bad throughput and therefore unsatisfying end-user experience. Furthermore, if you plan to use repeater mode on the CPEs in order to distribute the signal to the end-user's devices, you cannot use TP-Link's TDMA technique to avoid such interferences, so the maximum number of end-user's devices is limited purely depending on the overlapping WiFi cells (if they overlap at all).

To give more tips for a possibly suited setup using CPEs, I would need more information on your specific use case, a map with the locations of the APs, distances of the CPEs to each other and distances to the central supplying AP etc.

So it's not backward compatible with 2.4Ghz devices when 802.11n mode is configured? More information regarding your request will be made available soon.

802.11n is a standard for use in a certain frequency band to exchange data, but it has nothing to do with the actual frequency band it is used in. The CPE210's radio works in the 2.4 GHz band, the CPE510's radio uses 5 GHz.
